When a pharmaceutical company changes an SPC or PIL, a new version is published on medicines.ie. For each version, we show the dates it was published on medicines.ie and the reasons for change.
The update is due to IMB approval of an update to the SmPC according to the recommendations from the Pharmacovigilance Working Party (PhVWP) on somatropin. The wording changes in the SmPC are for harmonisation across somatropin products, and no new data is included.
4.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients. Any evidence of active malignant tumours. Intracranial neoplasm must be inactive and anti-tumour therapy should be completed prior to institution of therapy. Pregnancy and lactation, see 4.6. Somatropin should not be used for longitudinal growth promotion in children with closed epiphyses. Patients with acute critical illness suffering complications following open heart surgery, abdominal surgery, multiple accidental trauma, acute respiratory failure or similar conditions should not be treated with Norditropinsomatropin (, see section 4.4). Hypersensitivity to somatropin or to any of the excipients. In children with chronic renal disease, treatment with Norditropin SimpleXx should be discontinued at renal transplantation. 4.4 Special warnings and precautions for use Children treated with Norditropin SimpleXxsomatropin should be regularly assessed by a specialist in child growth. Norditropin SimpleXxSomatropin treatment should always be instigated by a physician with special knowledge of growth hormone insufficiency and its treatment. This is true also for the management of Turner syndrome, chronic renal disease and SGA. Data of final adult height following the use of Norditropin for children with chronic renal disease are not available. The stimulation of longitudinal growth in children can only be expected until epiphyseal closure. The dosage in children with chronic renal disease is individual and must be adjusted according to the individual response to therapy. The growth disturbance should be clearly established before Norditropin SimpleXx treatment by following growth on optimal treatment for renal disease over one year. Conservative management of uraemia with customary medicinal product and if needed dialysis should be maintained during Norditropin SimpleXx therapy. Patients with chronic renal disease normally experience a decline in renal function as part of the natural course of their illness. However, as a precautionary measure during Norditropin SimpleXx treatment renal function should be monitored for an excessive decline, or increase in the glomerular filtration rate (which could imply hyperfiltration). Treatment of growth hormone deficiency in patients with Prader-Willi syndrome There have been reports of sudden death after initiating growth hormonesomatropin therapy in patients with Prader-Willi syndrome, who had one or more of the following risk factors: severe obesity, history of upper airway obstruction or sleep apnoea, or unidentified respiratory infection. Growth hormone deficiency in adults Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Small for Gestational Age In short children born SGA other medical reasons or treatments that could explain growth disturbance should be ruled out before starting treatment. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Turner syndrome Monitoring of growth of hands and feet in Turner syndrome patients treated with somatropingrowth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, which is why otological evaluation is recommended on at least an annual basis. Chronic renal disease The dosage in children with chronic renal disease is individual and must be adjusted according to the individual response to therapy (see section 4.2). The growth disturbance should be clearly established before somatropinNorditropin SimpleXx treatment by following growth on optimal treatment for renal disease over one year. Conservative management of uraemia with customary medicinal product and if needed dialysis should be maintained during somatropinNorditropin SimpleXx therapy. Patients with chronic renal disease normally experience a decline in renal function as part of the natural course of their illness. However, as a precautionary measure during somatropinNorditropin SimpleXx treatment, renal function should be monitored for an excessive decline, or increase in the glomerular filtration rate (which could imply hyperfiltration). IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Tumours and malignancies In patients in complete remission from tumours or malignant disease, somatropingrowth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Leukaemia Leukaemia has been reported in a small number of growth hormone deficiency patients, some of whom have been treated with somatropin. However, there is no evidence that leukaemia incidence is increased in somatropingrowth hormone recipients without predisposition factors. Benign intracranial hypertension In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the somatropingrowth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If somatropingrowth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Thyroid function SomatropinGrowth hormone increases the extrathyroidal conversion of T4 to T3 and may, as such, unmask incipient hypothyroidism. Monitoring of thyroid function should therefore be conducted in all patients. In patients with hypopituitarism, standard replacement therapy must be closely monitored when somatropin therapy is administered. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to somatropinNorditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome.

In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.

In children with chronic renal disease, treatment with Norditropin SimpleXx should be discontinued at renal transplantation. 4.4 Special warnings and precautions for use Children treated with Norditropin SimpleXxsomatropin should be regularly assessed by a specialist in child growth. Norditropin SimpleXxSomatropin treatment should always be instigated by a physician with special knowledge of growth hormone insufficiency and its treatment. This is true also for the management of Turner syndrome, chronic renal disease and SGA. Data of final adult height following the use of Norditropin for children with chronic renal disease are not available. The stimulation of longitudinal growth in children can only be expected until epiphyseal closure. The dosage in children with chronic renal disease is individual and must be adjusted according to the individual response to therapy. The growth disturbance should be clearly established before Norditropin SimpleXx treatment by following growth on optimal treatment for renal disease over one year. Conservative management of uraemia with customary medicinal product and if needed dialysis should be maintained during Norditropin SimpleXx therapy. Patients with chronic renal disease normally experience a decline in renal function as part of the natural course of their illness. However, as a precautionary measure during Norditropin SimpleXx treatment renal function should be monitored for an excessive decline, or increase in the glomerular filtration rate (which could imply hyperfiltration). Treatment of growth hormone deficiency in patients with Prader-Willi syndrome There have been reports of sudden death after initiating growth hormonesomatropin therapy in patients with Prader-Willi syndrome, who had one or more of the following risk factors: severe obesity, history of upper airway obstruction or sleep apnoea, or unidentified respiratory infection. Growth hormone deficiency in adults Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Small for Gestational Age In short children born SGA other medical reasons or treatments that could explain growth disturbance should be ruled out before starting treatment. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Turner syndrome Monitoring of growth of hands and feet in Turner syndrome patients treated with somatropingrowth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, which is why otological evaluation is recommended on at least an annual basis. Chronic renal disease The dosage in children with chronic renal disease is individual and must be adjusted according to the individual response to therapy (see section 4.2). The growth disturbance should be clearly established before somatropinNorditropin SimpleXx treatment by following growth on optimal treatment for renal disease over one year. Conservative management of uraemia with customary medicinal product and if needed dialysis should be maintained during somatropinNorditropin SimpleXx therapy. Patients with chronic renal disease normally experience a decline in renal function as part of the natural course of their illness. However, as a precautionary measure during somatropinNorditropin SimpleXx treatment, renal function should be monitored for an excessive decline, or increase in the glomerular filtration rate (which could imply hyperfiltration). IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Tumours and malignancies In patients in complete remission from tumours or malignant disease, somatropingrowth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Leukaemia Leukaemia has been reported in a small number of growth hormone deficiency patients, some of whom have been treated with somatropin. However, there is no evidence that leukaemia incidence is increased in somatropingrowth hormone recipients without predisposition factors. Benign intracranial hypertension In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the somatropingrowth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If somatropingrowth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Thyroid function SomatropinGrowth hormone increases the extrathyroidal conversion of T4 to T3 and may, as such, unmask incipient hypothyroidism. Monitoring of thyroid function should therefore be conducted in all patients. In patients with hypopituitarism, standard replacement therapy must be closely monitored when somatropin therapy is administered. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to somatropinNorditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended.

At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome.

In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
Somatropin should not be used for longitudinal growth promotion in children with closed epiphyses. Patients with acute critical illness suffering complications following open heart surgery, abdominal surgery, multiple accidental trauma, acute respiratory failure or similar conditions should not be treated with Norditropinsomatropin (, see section 4.4). Hypersensitivity to somatropin or to any of the excipients.

Treatment of growth hormone deficiency in patients with Prader-Willi syndrome There have been reports of sudden death after initiating growth hormonesomatropin therapy in patients with Prader-Willi syndrome, who had one or more of the following risk factors: severe obesity, history of upper airway obstruction or sleep apnoea, or unidentified respiratory infection. Growth hormone deficiency in adults Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Small for Gestational Age In short children born SGA other medical reasons or treatments that could explain growth disturbance should be ruled out before starting treatment. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Turner syndrome Monitoring of growth of hands and feet in Turner syndrome patients treated with somatropingrowth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, which is why otological evaluation is recommended on at least an annual basis. Chronic renal disease The dosage in children with chronic renal disease is individual and must be adjusted according to the individual response to therapy (see section 4.2). The growth disturbance should be clearly established before somatropinNorditropin SimpleXx treatment by following growth on optimal treatment for renal disease over one year. Conservative management of uraemia with customary medicinal product and if needed dialysis should be maintained during somatropinNorditropin SimpleXx therapy. Patients with chronic renal disease normally experience a decline in renal function as part of the natural course of their illness. However, as a precautionary measure during somatropinNorditropin SimpleXx treatment, renal function should be monitored for an excessive decline, or increase in the glomerular filtration rate (which could imply hyperfiltration). IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Tumours and malignancies In patients in complete remission from tumours or malignant disease, somatropingrowth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Leukaemia Leukaemia has been reported in a small number of growth hormone deficiency patients, some of whom have been treated with somatropin. However, there is no evidence that leukaemia incidence is increased in somatropingrowth hormone recipients without predisposition factors. Benign intracranial hypertension In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the somatropingrowth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If somatropingrowth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Thyroid function SomatropinGrowth hormone increases the extrathyroidal conversion of T4 to T3 and may, as such, unmask incipient hypothyroidism. Monitoring of thyroid function should therefore be conducted in all patients. In patients with hypopituitarism, standard replacement therapy must be closely monitored when somatropin therapy is administered. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to somatropinNorditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended.

At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome.

In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
Patients with acute critical illness suffering complications following open heart surgery, abdominal surgery, multiple accidental trauma, acute respiratory failure or similar conditions should not be treated with Norditropinsomatropin (, see section 4.4).
Hypersensitivity to somatropin or to any of the excipients. In children with chronic renal disease, treatment with Norditropin SimpleXx should be discontinued at renal transplantation. 4.4 Special warnings and precautions for use Children treated with Norditropin SimpleXxsomatropin should be regularly assessed by a specialist in child growth. Norditropin SimpleXxSomatropin treatment should always be instigated by a physician with special knowledge of growth hormone insufficiency and its treatment. This is true also for the management of Turner syndrome, chronic renal disease and SGA. Data of final adult height following the use of Norditropin for children with chronic renal disease are not available. The stimulation of longitudinal growth in children can only be expected until epiphyseal closure. The dosage in children with chronic renal disease is individual and must be adjusted according to the individual response to therapy. The growth disturbance should be clearly established before Norditropin SimpleXx treatment by following growth on optimal treatment for renal disease over one year.

However, as a precautionary measure during somatropinNorditropin SimpleXx treatment, renal function should be monitored for an excessive decline, or increase in the glomerular filtration rate (which could imply hyperfiltration). IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Tumours and malignancies In patients in complete remission from tumours or malignant disease, somatropingrowth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Leukaemia Leukaemia has been reported in a small number of growth hormone deficiency patients, some of whom have been treated with somatropin. However, there is no evidence that leukaemia incidence is increased in somatropingrowth hormone recipients without predisposition factors. Benign intracranial hypertension In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the somatropingrowth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If somatropingrowth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Thyroid function SomatropinGrowth hormone increases the extrathyroidal conversion of T4 to T3 and may, as such, unmask incipient hypothyroidism. Monitoring of thyroid function should therefore be conducted in all patients. In patients with hypopituitarism, standard replacement therapy must be closely monitored when somatropin therapy is administered. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to somatropinNorditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome. In children headache Skin and subcutaneous tissue disorders In adults pruritus In children rash NOS Musculoskeletal, connective tissue and bone disorders In adults arthralgia, joint stiffness and myalgia In adults muscle stiffness In children arthralgia and myalgia General disorders and administration site conditions In adults peripheral oedema (see text above) In adults and children injection site pain. In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
In children with chronic renal disease, treatment with Norditropin SimpleXx should be discontinued at renal transplantation.
4.4 Special warnings and precautions for use
Children treated with Norditropin SimpleXxsomatropin should be regularly assessed by a specialist in child growth. Norditropin SimpleXxSomatropin treatment should always be instigated by a physician with special knowledge of growth hormone insufficiency and its treatment. This is true also for the management of Turner syndrome, chronic renal disease and SGA. Data of final adult height following the use of Norditropin for children with chronic renal disease are not available.
The stimulation of longitudinal growth in children can only be expected until epiphyseal closure.
The dosage in children with chronic renal disease is individual and must be adjusted according to the individual response to therapy. The growth disturbance should be clearly established before Norditropin SimpleXx treatment by following growth on optimal treatment for renal disease over one year. Conservative management of uraemia with customary medicinal product and if needed dialysis should be maintained during Norditropin SimpleXx therapy.
Patients with chronic renal disease normally experience a decline in renal function as part of the natural course of their illness. However, as a precautionary measure during Norditropin SimpleXx treatment renal function should be monitored for an excessive decline, or increase in the glomerular filtration rate (which could imply hyperfiltration).
Treatment of growth hormone deficiency in patients with Prader-Willi syndrome
There have been reports of sudden death after initiating growth hormonesomatropin therapy in patients with Prader-Willi syndrome, who had one or more of the following risk factors: severe obesity, history of upper airway obstruction or sleep apnoea, or unidentified respiratory infection.
Growth hormone deficiency in adults Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Small for Gestational Age In short children born SGA other medical reasons or treatments that could explain growth disturbance should be ruled out before starting treatment. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Turner syndrome Monitoring of growth of hands and feet in Turner syndrome patients treated with somatropingrowth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, which is why otological evaluation is recommended on at least an annual basis. Chronic renal disease The dosage in children with chronic renal disease is individual and must be adjusted according to the individual response to therapy (see section 4.2).

If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome. In children headache Skin and subcutaneous tissue disorders In adults pruritus In children rash NOS Musculoskeletal, connective tissue and bone disorders In adults arthralgia, joint stiffness and myalgia In adults muscle stiffness In children arthralgia and myalgia General disorders and administration site conditions In adults peripheral oedema (see text above) In adults and children injection site pain. In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
Small for Gestational Age
In short children born SGA other medical reasons or treatments that could explain growth disturbance should be ruled out before starting treatment. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Turner syndrome Monitoring of growth of hands and feet in Turner syndrome patients treated with somatropingrowth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, which is why otological evaluation is recommended on at least an annual basis. Chronic renal disease The dosage in children with chronic renal disease is individual and must be adjusted according to the individual response to therapy (see section 4.2). The growth disturbance should be clearly established before somatropinNorditropin SimpleXx treatment by following growth on optimal treatment for renal disease over one year. Conservative management of uraemia with customary medicinal product and if needed dialysis should be maintained during somatropinNorditropin SimpleXx therapy. Patients with chronic renal disease normally experience a decline in renal function as part of the natural course of their illness. However, as a precautionary measure during somatropinNorditropin SimpleXx treatment, renal function should be monitored for an excessive decline, or increase in the glomerular filtration rate (which could imply hyperfiltration). IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Tumours and malignancies In patients in complete remission from tumours or malignant disease, somatropingrowth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Leukaemia Leukaemia has been reported in a small number of growth hormone deficiency patients, some of whom have been treated with somatropin. However, there is no evidence that leukaemia incidence is increased in somatropingrowth hormone recipients without predisposition factors. Benign intracranial hypertension In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the somatropingrowth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If somatropingrowth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Thyroid function SomatropinGrowth hormone increases the extrathyroidal conversion of T4 to T3 and may, as such, unmask incipient hypothyroidism. Monitoring of thyroid function should therefore be conducted in all patients. In patients with hypopituitarism, standard replacement therapy must be closely monitored when somatropin therapy is administered. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to somatropinNorditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy.

In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3.

Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached.

Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome. In children headache Skin and subcutaneous tissue disorders In adults pruritus In children rash NOS Musculoskeletal, connective tissue and bone disorders In adults arthralgia, joint stiffness and myalgia In adults muscle stiffness In children arthralgia and myalgia General disorders and administration site conditions In adults peripheral oedema (see text above) In adults and children injection site pain. In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
Experience with patients with Silver-Russell syndrome is limited. Turner syndrome Monitoring of growth of hands and feet in Turner syndrome patients treated with somatropingrowth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, which is why otological evaluation is recommended on at least an annual basis. Chronic renal disease The dosage in children with chronic renal disease is individual and must be adjusted according to the individual response to therapy (see section 4.2). The growth disturbance should be clearly established before somatropinNorditropin SimpleXx treatment by following growth on optimal treatment for renal disease over one year. Conservative management of uraemia with customary medicinal product and if needed dialysis should be maintained during somatropinNorditropin SimpleXx therapy. Patients with chronic renal disease normally experience a decline in renal function as part of the natural course of their illness. However, as a precautionary measure during somatropinNorditropin SimpleXx treatment, renal function should be monitored for an excessive decline, or increase in the glomerular filtration rate (which could imply hyperfiltration). IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Tumours and malignancies In patients in complete remission from tumours or malignant disease, somatropingrowth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Leukaemia Leukaemia has been reported in a small number of growth hormone deficiency patients, some of whom have been treated with somatropin. However, there is no evidence that leukaemia incidence is increased in somatropingrowth hormone recipients without predisposition factors. Benign intracranial hypertension In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the somatropingrowth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If somatropingrowth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Thyroid function SomatropinGrowth hormone increases the extrathyroidal conversion of T4 to T3 and may, as such, unmask incipient hypothyroidism. Monitoring of thyroid function should therefore be conducted in all patients. In patients with hypopituitarism, standard replacement therapy must be closely monitored when somatropin therapy is administered. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to somatropinNorditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone.

However, there is no evidence that leukaemia incidence is increased in somatropingrowth hormone recipients without predisposition factors. Benign intracranial hypertension In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the somatropingrowth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If somatropingrowth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Thyroid function SomatropinGrowth hormone increases the extrathyroidal conversion of T4 to T3 and may, as such, unmask incipient hypothyroidism. Monitoring of thyroid function should therefore be conducted in all patients. In patients with hypopituitarism, standard replacement therapy must be closely monitored when somatropin therapy is administered. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to somatropinNorditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome. In children headache Skin and subcutaneous tissue disorders In adults pruritus In children rash NOS Musculoskeletal, connective tissue and bone disorders In adults arthralgia, joint stiffness and myalgia In adults muscle stiffness In children arthralgia and myalgia General disorders and administration site conditions In adults peripheral oedema (see text above) In adults and children injection site pain. In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
Girls with Turner syndrome generally have an increased risk of otitis media, which is why otological evaluation is recommended on at least an annual basis. Chronic renal disease The dosage in children with chronic renal disease is individual and must be adjusted according to the individual response to therapy (see section 4.2). The growth disturbance should be clearly established before somatropinNorditropin SimpleXx treatment by following growth on optimal treatment for renal disease over one year. Conservative management of uraemia with customary medicinal product and if needed dialysis should be maintained during somatropinNorditropin SimpleXx therapy. Patients with chronic renal disease normally experience a decline in renal function as part of the natural course of their illness. However, as a precautionary measure during somatropinNorditropin SimpleXx treatment, renal function should be monitored for an excessive decline, or increase in the glomerular filtration rate (which could imply hyperfiltration). IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached.

Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome. In children headache Skin and subcutaneous tissue disorders In adults pruritus In children rash NOS Musculoskeletal, connective tissue and bone disorders In adults arthralgia, joint stiffness and myalgia In adults muscle stiffness In children arthralgia and myalgia General disorders and administration site conditions In adults peripheral oedema (see text above) In adults and children injection site pain. In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
Chronic renal disease
The dosage in children with chronic renal disease is individual and must be adjusted according to the individual response to therapy (see section 4.2). The growth disturbance should be clearly established before somatropinNorditropin SimpleXx treatment by following growth on optimal treatment for renal disease over one year. Conservative management of uraemia with customary medicinal product and if needed dialysis should be maintained during somatropinNorditropin SimpleXx therapy. Patients with chronic renal disease normally experience a decline in renal function as part of the natural course of their illness. However, as a precautionary measure during somatropinNorditropin SimpleXx treatment, renal function should be monitored for an excessive decline, or increase in the glomerular filtration rate (which could imply hyperfiltration). IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Tumours and malignancies In patients in complete remission from tumours or malignant disease, somatropingrowth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Leukaemia Leukaemia has been reported in a small number of growth hormone deficiency patients, some of whom have been treated with somatropin. However, there is no evidence that leukaemia incidence is increased in somatropingrowth hormone recipients without predisposition factors. Benign intracranial hypertension In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the somatropingrowth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If somatropingrowth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Thyroid function SomatropinGrowth hormone increases the extrathyroidal conversion of T4 to T3 and may, as such, unmask incipient hypothyroidism. Monitoring of thyroid function should therefore be conducted in all patients. In patients with hypopituitarism, standard replacement therapy must be closely monitored when somatropin therapy is administered. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to somatropinNorditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis.

If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the somatropingrowth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If somatropingrowth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Thyroid function SomatropinGrowth hormone increases the extrathyroidal conversion of T4 to T3 and may, as such, unmask incipient hypothyroidism. Monitoring of thyroid function should therefore be conducted in all patients. In patients with hypopituitarism, standard replacement therapy must be closely monitored when somatropin therapy is administered. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to somatropinNorditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome. In children headache Skin and subcutaneous tissue disorders In adults pruritus In children rash NOS Musculoskeletal, connective tissue and bone disorders In adults arthralgia, joint stiffness and myalgia In adults muscle stiffness In children arthralgia and myalgia General disorders and administration site conditions In adults peripheral oedema (see text above) In adults and children injection site pain. In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
IGF-I
In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range.
Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached.
Tumours and malignancies
In patients in complete remission from tumours or malignant disease, somatropingrowth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy.

The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare.

In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4).

Leukaemia
Leukaemia has been reported in a small number of growth hormone deficiency patients, some of whom have been treated with somatropin. However, there is no evidence that leukaemia incidence is increased in somatropingrowth hormone recipients without predisposition factors. Benign intracranial hypertension In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the somatropingrowth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If somatropingrowth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Thyroid function SomatropinGrowth hormone increases the extrathyroidal conversion of T4 to T3 and may, as such, unmask incipient hypothyroidism. Monitoring of thyroid function should therefore be conducted in all patients. In patients with hypopituitarism, standard replacement therapy must be closely monitored when somatropin therapy is administered. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to somatropinNorditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy.

One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome. In children headache Skin and subcutaneous tissue disorders In adults pruritus In children rash NOS Musculoskeletal, connective tissue and bone disorders In adults arthralgia, joint stiffness and myalgia In adults muscle stiffness In children arthralgia and myalgia General disorders and administration site conditions In adults peripheral oedema (see text above) In adults and children injection site pain. In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If somatropingrowth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Thyroid function SomatropinGrowth hormone increases the extrathyroidal conversion of T4 to T3 and may, as such, unmask incipient hypothyroidism. Monitoring of thyroid function should therefore be conducted in all patients. In patients with hypopituitarism, standard replacement therapy must be closely monitored when somatropin therapy is administered. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to somatropinNorditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk.

Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome. In children headache Skin and subcutaneous tissue disorders In adults pruritus In children rash NOS Musculoskeletal, connective tissue and bone disorders In adults arthralgia, joint stiffness and myalgia In adults muscle stiffness In children arthralgia and myalgia General disorders and administration site conditions In adults peripheral oedema (see text above) In adults and children injection site pain. In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
Thyroid function
SomatropinGrowth hormone increases the extrathyroidal conversion of T4 to T3 and may, as such, unmask incipient hypothyroidism. Monitoring of thyroid function should therefore be conducted in all patients. In patients with hypopituitarism, standard replacement therapy must be closely monitored when somatropin therapy is administered. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to somatropinNorditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited.

One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome. In children headache Skin and subcutaneous tissue disorders In adults pruritus In children rash NOS Musculoskeletal, connective tissue and bone disorders In adults arthralgia, joint stiffness and myalgia In adults muscle stiffness In children arthralgia and myalgia General disorders and administration site conditions In adults peripheral oedema (see text above) In adults and children injection site pain. In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
Scoliosis Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, somatropingrowth hormone treatment has not been shown to increase the incidence or severity of scoliosis. Insulin sensitivity Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk.

Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome. In children headache Skin and subcutaneous tissue disorders In adults pruritus In children rash NOS Musculoskeletal, connective tissue and bone disorders In adults arthralgia, joint stiffness and myalgia In adults muscle stiffness In children arthralgia and myalgia General disorders and administration site conditions In adults peripheral oedema (see text above) In adults and children injection site pain. In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
Insulin sensitivity
Because somatropin may reduce insulin sensitivity, patients should be monitored for evidence of glucose intolerance (see section 4.5). For patients with diabetes mellitus, the insulin dose may require adjustment after somatropin containing product therapy is instituted. Patients with diabetes or glucose intolerance should be monitored closely during somatropin therapy. Blood glucose and insulin In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk of diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, somatropingrowth hormone should not be administered. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. IGF-I In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk.

If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-I level within the normal range. Some of the height gain obtained with treating short children born SGA with somatropin may be lost if treatment is stopped before final height is reached. Antibodies As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare.

In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.

The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome.

In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
Antibodies
As with all somatropin containing products, a small percentage of patients may develop antibodies to somatropin. The binding capacity of these antibodies is low and there is no effect on growth rate. Testing for antibodies to somatropin should be carried out in any patient who fails to respond to therapy. Somatropin has been found to influence carbohydrate metabolism, therefore, patients should be observed for evidence of glucose intolerance. In Turner syndrome and SGA children it is recommended to measure fasting insulin and blood glucose before start of treatment and annually thereafter. In patients with increased risk for diabetes mellitus (e.g. familial history of diabetes, obesity, severe insulin resistance, acanthosis nigricans) oral glucose tolerance testing (OGTT) should be performed. If overt diabetes occurs, growth hormone should not be administered. In Turner syndrome and SGA children it is recommended to measure the IGF-I level before start of treatment and twice a year thereafter. If on repeated measurements IGF-I levels exceed +2 SD compared to references for age and pubertal status, the dose should be reduced to achieve an IGF-1 level within the normal range. Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary. Growth hormone deficiency in adults is a lifelong disease and needs to be treated accordingly, however, experience in patients older than 60 years and in patients with more than five years of treatment in adult growth hormone deficiency is still limited. Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes.

Clinical trial experience Two placebo-controlled clinical trials of patients in intensive care units have demonstrated an increased mortality among patients suffering from acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma or acute respiratory failure, who were treated with somatropin in high doses (5.3-8 mg/day). The safety of continuing somatropingrowth hormone treatment in patients receiving replacement doses for approved indications who concurrently develop these illnesses has not been established. Therefore, the potential benefit of treatment continuation with somatropingrowth hormone in patients having acute critical illnesses should be weighed against the potential risk. One open-label, randomised clinical trial (dose range 45-90 µg/kg/day) with patients with Turner syndrome indicated a tendency for a dose-dependent risk of otitis externa and otitis media. The increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. 4.5 Interaction with other medicinal products and other forms of interaction Concomitant treatment with glucocorticoids inhibits the growth-promoting effects of somatropin containing products. Patients with ACTH deficiency should have their glucocorticoid replacement therapy carefully adjusted to avoid any inhibitory effect on somatropingrowth hormone.Concomitant glucocorticoid therapy may inhibit growth and thereby oppose the growth promoting effect of Norditropin SimpleXx. The effect of growth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown. The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare. Clinical trial experience: System organ classes Very common (≥> 1/10) Common (≥> 1/100; to << 1/10) Uncommon (≥> 1/1,000; to << 1/100) Rare (≥> 1/10,000; to << 1/1,000) Metabolism and nutrition disorders In adults Diabetes mellitus type 2 (See Post-marketing experience) Nervous system disorders In adults headache and paraesthesia In adults carpal tunnel syndrome. In children headache Skin and subcutaneous tissue disorders In adults pruritus In children rash NOS Musculoskeletal, connective tissue and bone disorders In adults arthralgia, joint stiffness and myalgia In adults muscle stiffness In children arthralgia and myalgia General disorders and administration site conditions In adults peripheral oedema (see text above) In adults and children injection site pain. In children injection site reaction NOS In children peripheral oedema In children with Turner syndrome increased growth of hands and feet has been reported during somatropinGH therapy. A tendency for increased incidence of otitis media in Turner syndrome patients treated with high doses of Norditropin has been observed in one open-label randomised clinical trial. However, the increase in ear infections did not result in more ear operations/ tube insertions compared to the lower dose group in the trial. Post-marketing experience: In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported and are by an overall judgement considered possibly related to Norditropin treatment. Neoplasms benign and malignant (inluding cysts and polyps) Leukaemia has been reported in a small number of growth hormone deficiency patients (see section 4.4). Immune system disorders Hypersensitivity (see section 4.3). Formation of antibodies directed against somatropin. The titres and binding capacities of these antibodies have been very low and have not interfered with the growth response to Norditropin administration. Endocrine disorders Hypothyroidism. Decrease in serum thyroxin levels (please refer tosee section 4.4). Metabolism and nutrition disorders Hyperglycemia, (see section 4.4). Nervous system disorders Benign intracranial hypertension (see section 4.4). Musculoskeletal and connective tissue disorders Slipped capital femoral epiphysis. Slipped capital femoral epiphysis may occur more frequently in patients with endocrine disorders. Legg-Calvé-Perthes disease. Legg-Calvé-Perthes disease may occur more frequently in patients with short stature. Investigations Increase in blood alkaline phosphatase level.
Experience in initiating treatment in SGA patients near onset of puberty is limited. It is therefore not recommended to initiate treatment near onset of puberty. Experience with patients with Silver-Russell syndrome is limited. Some of the height gain obtained with treating short children born SGA with growth hormone may be lost if treatment is stopped before final height is reached. Serum thyroxine levels may fall during treatment with Norditropin SimpleXx due to the increased peripheral deiodination of T4 to T3. In patients with a pituitary disease in progression, hypothyroidism may develop. Patients with Turner syndrome have an increased risk of developing primary hypothyroidism associated with anti-thyroid antibodies. As hypothyroidism interferes with the response to Norditropin SimpleXx therapy patients should have their thyroid function tested regularly, and should receive replacement therapy with thyroid hormone when indicated. Monitoring of growth of hands and feet in Turner syndrome patients treated with growth hormone is recommended and a dose reduction to the lower part of the dose range should be considered if increased growth is observed. Girls with Turner syndrome generally have an increased risk of otitis media, why otological evaluation is recommended on at least an annual basis. In insulin treated patients adjustment of insulin dose may be needed after initiation of Norditropin SimpleXx treatment. Patients with growth hormone deficiency secondary to an intracranial lesion should be examined frequently for progression or recurrence of the underlying disease process. Leukaemia has been reported in a small number of growth hormone deficient patients some of whom have been treated with somatropin. Based on 10 years global assessment there is no increased risk of development of leukaemia during somatropin treatment. In patients in complete remission from tumours or malignant disease, growth hormone therapy has not been associated with an increased relapse rate. Nevertheless, patients who have achieved complete remission of malignant disease should be followed closely for relapse after commencement of Norditropin SimpleXx therapy. Scoliosis may progress in any child during rapid growth. Signs of scoliosis should be monitored during treatment. However, growth hormone treatment has not been shown to increase the incidence or severity of scoliosis. In the event of severe or recurrent headache, visual problems, nausea, and/or vomiting, a funduscopy for papilloedema is recommended. If papilloedema is confirmed, a diagnosis of benign intracranial hypertension should be considered and if appropriate the growth hormone treatment should be discontinued. At present there is insufficient evidence to guide clinical decision making in patients with resolved intracranial hypertension. If growth hormone treatment is restarted, careful monitoring for symptoms of intracranial hypertension is necessary.

Data from an interaction study performed in growth hormone deficient adults, suggests that somatropin administration may increase the clearance of compounds known to be metabolised by cytochrome P450 isoenzymes. The clearance of compounds metabolised by cytochrome P450 3A4 (e.g. sex steroids, corticosteroids, anticonvulsants and cyclosporine) may be especially increased resulting in lower plasma levels of these compounds. The clinical significance of this is unknown.
The effect of somatropingrowth hormone on final height can also be influenced by additional therapy with other hormones, e.g. gonadotrophin, anabolic steroids, estrogen and thyroid hormone. In insulin treated patients adjustment of insulin dose may be needed after initiation of somatropin treatment (see section 4.4). 4.6 Fertility, Ppregnancy and lactation Animal studies are insufficient with regard to effects on pregnancy, embryofoetal development, parturition or postnatal development. No clinical data on exposed pregnancies are available. Therefore, somatropin containing products are not recommended during pregnancy and in woman of childbearing potential not using contraception. There have been no clinical studies conducted with somatropin containing products in breast-feeding women. It is not known whether somatropin is excreted in human milk. Therefore caution should be exercised when somatropin containing products are administered to breast-feeding women.Currently there is insufficient evidence of safety of somatropin therapy during pregnancy. The possibility that somatropin is secreted in breast milk cannot be discounted. 4.7 Effects on ability to drive and use machines No influence on the ability to drive and use machines. 4.8 Undesirable effects Growth hormone deficient patients are characterised by extracellular volume deficit. When treatment with somatropin is initiated, this deficit is corrected. Fluid retention with peripheral oedema may occur especially in adults. Carpal tunnel syndrome is uncommon, but may be seen in adults. The symptoms are usually transient, dose dependeant and may require transient dose reduction. Mild arthralgia, muscle pain and paresthesia may also occur, but are usually self-limiting. Adverse reactions in children are uncommon or rare.

4.1 Therapeutic indications
Children:
Growth failure due to growth hormone deficiency (
GHD) Adults:
Adults:
Childhood onset growth hormone deficiency:
Patients with childhood onset GHD should be re-evaluated for growth hormone secretory capacity after growth completion. Testing is not required for those with more than three pituitary hormone deficits, with severe GHD due to a defined genetic cause, due to structural hypothalamic pituitary abnormalities, due to central nervous system tumours or due to high-dose cranial irradiation, or with GHD secondary to a pituitary/hypothalamic disease or insult, if measurements of IGF-I is < -2 SDS after at least four weeks off growth hormone treatment.
In all other patients an IGF-I measurement and one growth hormone stimulation test is required.
Adult onset growth hormone deficiency:
Pronounced
growth hormone deficiency GHD in known hypothalamic-pituitary disease, cranial irradiation and traumatic brain injury. GHD should be associated with (one other deficient axis, other than prolactin). GHD should be demonstrated by one provocative test after institution of adequate replacement therapy for any other deficient axis.
Childhood onset growth hormone insufficiency, reconfirmed by two provocative tests.
4.2 Posology and method of administration
Growth hormone insufficiency
25-35
μg/kg/day or 0.7-1.0 mg/m2/day Equal to: 0.07-0.1 IU/kg/day (2-3 IU/m2/day) When GHD persists after growth completion, growth hormone treatment should be continued to achieve full somatic adult development including lean body mass and bone mineral accrual (for guidance on dosing, see Replacement therapy in adults). Turner syndrome 45-67 μg/kg/day or 1.3-2.0 mg/m2/day Equal to: 0.13-0.2 IU/kg/day (3.9-6 IU/m2/day) Chronic Renal Disease 50 μg/kg/day or 1.4 mg/m2/day Equal to: 0.14 IU/kg/day (4.3 IU/m2/day) Small for Gestational Age 35 μg/kg/day or 1.0 mg/m2/day Equal to: 0.1 IU/kg/day (3 IU/m2/day) Adults: Replacement therapy in adults The dosage must be adjusted to the need of the individual patient. In patients with childhood onset GHD, the recommended dose to restart is 0.2-0.5 mg/day with subsequent dose adjustment on the basis of IGF-I concentration determination. In patients with adult onset GHD, i t is recommended to start treatment with a low dose: 0.1-0.3 mg/day (equal to 0.3-0.9 IU/day). It is recommended to increase the dosage gradually at monthly intervals based on the clinical response and the patient’s experience of adverse events. Serum insulin-like growth factor I (IGF-I) can be used as guidance for the dose titration. Women may require higher doses than men, with men showing an increasing IGF-I sensitivity over time. This means that there is a risk that women, especially those on oral oestrogen replacement are under-treated while men are over treated. Dose requirements decline with age. Maintenance dosages vary considerably from person to person, but seldom exceed 1.0 mg/day (equal to 3 IU/day). 4.4 Special warnings and precautions for use The stimulation of skeletal longitudinal growth in children can only be expected until epiphyseal closure.
Equal to: 0.07-0.1 IU/kg/day (2-3 IU/m2/day)
When GHD persists after growth completion, growth hormone treatment should be continued to achieve full somatic adult development including lean body mass and bone mineral accrual (for guidance on dosing, see Replacement therapy in adults).
45-67
μg/kg/day or 1.3-2.0 mg/m2/day Equal to: 0.13-0.2 IU/kg/day (3.9-6 IU/m2/day) Chronic Renal Disease 50 μg/kg/day or 1.4 mg/m2/day Equal to: 0.14 IU/kg/day (4.3 IU/m2/day) Small for Gestational Age 35 μg/kg/day or 1.0 mg/m2/day Equal to: 0.1 IU/kg/day (3 IU/m2/day) Adults: Replacement therapy in adults The dosage must be adjusted to the need of the individual patient. In patients with childhood onset GHD, the recommended dose to restart is 0.2-0.5 mg/day with subsequent dose adjustment on the basis of IGF-I concentration determination. In patients with adult onset GHD, i t is recommended to start treatment with a low dose: 0.1-0.3 mg/day (equal to 0.3-0.9 IU/day).

Maintenance dosages vary considerably from person to person, but seldom exceed 1.0 mg/day (equal to 3 IU/day). 4.4 Special warnings and precautions for use The stimulation of skeletal longitudinal growth in children can only be expected until epiphyseal closure.

The change concerns the number of stimulation (provocative) tests from two to one, as follows:
4.1. Therapeutic Indications
Pronounced growth hormone deficiency in known hypothalamic-pituitary disease (one other deficient axis, other than prolactin), demonstrated by one provocative test after institution of adequate replacement therapy for any other deficient axis.
The amended SmPC should be used with immediate effect and previous versions destroyed. The amended SmPC is version 5 revision date (SmPC section 10) April 2008.
The primary purpose of the update is to implement revised standard requirements for SPCs so the majority of the changes are editorial. The principal changes are:
Section 1
Section 2
The content of somatropin per ml is now given in full.
A reference to excipients is now included.
Section 4.1
Growth hormone insufficiency has been changed to growth hormone deficiency.
Section 4.2
Reference to prescribing by specialist moved to beginning of section.
Reference to sc administration in evening moved to end of section.
'Prescription only' deleted.
Small for gestational age dosage changed from 1 mg/m2/day to 1.0 mg/m2/day.
Starting dose for adults changed from 0.15-0.3 mg/day (equal to 0.45-0.9 IU/day) to 0.1-0.3 mg/day (equal to 0.3-0.9 IU/day).
Section 4.4
Second paragraph: "…until the epiphyseal discs are closed" changed to "…until epiphyseal closure".
The paragraph concerning slipped capital femoral epiphysis has been moved to section 4.8 (with some amendment).
Section 4.7
"No effects" changed to "No influence on the ability to drive and use machines".
Section 4.8
In the first paragraph, the word 'transient' has been introduced with regard to possible dose reduction in respect of oedema and carpal tunnel syndrome in adults.
The listing of adverse reactions seen in clinical trials has been put into tabular format.
The amended text from section 4.4 concerning slipped capital femoral epiphysis has been included under the sub-section 'Post marketing experience'.
Section 6.5
Reworded but with exactly same meaning.
Section 6.6
Reference to instructions for use of NordiPen deleted.
Section 10
