4.4 Special warnings and precautions for use
[…]
Interference with serological testing
Interference with Coombs tests may occur, as Rocephin may lead to false-positive test results. Rocephin can also lead to false-positive test results for galactosaemia (see section 4.8).
Non-enzymatic methods for the glucose determination in urine may give false-positive results. Urine glucose determination during therapy with Rocephin should be done enzymatically (see section 4.8).
The presence of ceftriaxone may falsely lower estimated blood glucose values obtained with some blood glucose monitoring systems. Please refer to instructions for use for each system. Alternative testing methods should be used if necessary.
[…]
4.8 Undesirable effects
[…]
Description of selected adverse reactions
Infections and infestations
Reports of diarrhoea following the use of ceftriaxone may be associated with Clostridium difficile. Appropriate fluid and electrolyte management should be instituted (see section 4.4).
Ceftriaxone-calcium salt precipitation
Rarely, severe, and in some cases, fatal, adverse reactions have been reported in pre-term and full-term neonates (aged < 28 days) who had been treated with intravenous ceftriaxone and calcium. Precipitations of ceftriaxone-calcium salt have been observed in lung and kidneys post-mortem. The high risk of precipitation in neonates is a result of their low blood volume and the longer half-life of ceftriaxone compared with adults (see sections 4.3, 4.4, and 5.2).
Cases of renal precipitation have been reported, primarily in children older than 3 years of age and who have been treated with either high daily doses (e.g. ³ 80 mg/kg/day) or total doses exceeding 10 grams and who presented with other risk factors (e.g. fluid restrictions or confinement to bed). The risk of precipitate formation is increased in immobilized or dehydrated patients. This event may be symptomatic or asymptomatic, may lead to renal insufficiency and anuria, and is reversible upon discontinuation of ceftriaxone (see section 4.4).
Cases of ceftriaxone precipitation in the urinary tract have been reported, mostly in children treated with high doses (e.g. ≥ 80 mg/kg/day or total doses exceeding 10 grams) and who have other risk factors (e.g. dehydration, confinement to bed). This event may be asymptomatic or symptomatic, and may lead to ureteric obstruction and postrenal acute renal failure, but is usually reversible upon discontinuation of ceftriaxone (see section 4.4).

Duration of therapy
The duration of therapy varies according to the course of the disease. As with antibiotic therapy in general, administration of ceftriaxone should be continued for 48 - 72 hours after the patient has become afebrile or evidence of bacterial eradication has been achieved.
Older people
The dosages recommended for adults require no modification in older people provided that renal and hepatic function is satisfactory.
Patients with hepatic impairment
Available data do not indicate the need for dose adjustment in mild or moderate liver function impairment provided renal function is not impaired.
There are no study data in patients with severe hepatic impairment (see section 5.2).
Patients with renal impairment
In patients with impaired renal function, there is no need to reduce the dosage of ceftriaxone provided hepatic function is not impaired. Only in cases of preterminal renal failure (creatinine clearance < 10 ml/min) should the ceftriaxone dosage not exceed 2 g daily.
In patients undergoing dialysis no additional supplementary dosing is required following the dialysis. Ceftriaxone is not removed by peritoneal- or haemodialysis. Close clinical monitoring for safety and efficacy is advised.
Patients with severe hepatic and renal impairment
In patients with both severe renal and hepatic dysfunction, close clinical monitoring for safety and efficacy is advised.
Method of administration
Rocephin can be administered by intravenous infusion over at least 30 minutes (preferred route) or by slow intravenous injection over 5 minutes, or by deep intramuscular injection. Intravenous intermittent injection should be given over 5 minutes preferably in larger veins. Intravenous doses of 50 mg/kg or more in infants and children up to 12 years of age should be given by infusion. In neonates, intravenous doses should be given over 60 minutes to reduce the potential risk of bilirubin encephalopathy (see section 4.3 and 4.4).Intramuscular injections should be injected well within the bulk of a relatively large muscle and not more than 1 g should be injected at one site. Intramuscular administration should be considered when the intravenous route is not possible or less appropriate for the patient. For doses greater than 2 g intravenous administration should be used.
IfAs the lidocaine is used as a solvent used is lidocaine, the resulting solution should never be administered intravenously (see section 4.3). The information in the Summary of Product Characteristics of lidocaine should be considered.
Ceftriaxone is contraindicated in neonates (≤ 28 days) if they require (or are expected to require) treatment with calcium-containing intravenous solutions, including continuous calcium-containing infusions such as parenteral nutrition, because of the risk of precipitation of ceftriaxone-calcium (see section 4.3).
Diluents containing calcium, (e.g. Ringer’s solution or Hartmann’s solution), should not be used to reconstitute ceftriaxone vials or to further dilute a reconstituted vial for intravenous administration because a precipitate can form. Precipitation of ceftriaxone-calcium can also occur when ceftriaxone is mixed with calcium-containing solutions in the same intravenous administration line. Therefore, ceftriaxone and calcium-containing solutions must not be mixed or administered simultaneously (see sections 4.3, 4.4 and 6.2).
For pre-operative prophylaxis of surgical site infections, ceftriaxone should be administered 30‑90 minutes prior to surgery.
For instructions on reconstitution of the medicinal product before administration, see section 6.6.
Rocephin may be administered by deep intramuscular injection only after reconstitution of the solution according to the directions given below. For instructions on reconstitution of the product before administration, see section 6.6.
Dosage and mode of administration should be determined by the severity of the infection, susceptibility of the causative organism and the patient's condition. Under most circumstances a once-daily dose - or, in the specified indications, a single dose - will give satisfactory therapeutic results.
Adults and children 12 years and over
Standard therapeutic dosage: 1g once daily.
Severe infections: 2 - 4g daily, normally as a single dose every 24 hours.
The duration of therapy varies according to the course of the disease. As with antibiotic therapy in general, administration of Rocephin should be continued for a minimum of 48 to 72 hours after the patient has become afebrile or evidence of bacterial eradication has been obtained.
Acute, uncomplicated gonorrhoea: A single dose of 250mg intramuscularly should be administered. Simultaneous administration of probenecid is not indicated.
Peri-operative prophylaxis: Usually 1g as a single intramuscular dose 30-90 minutes prior to surgery. In colorectal surgery, 2g should be given intramuscularly, in conjunction with a suitable agent against anaerobic bacteria.
Elderly
These dosages do not require modification in elderly patients provided that renal and hepatic function are satisfactory (see below).
Children under 12 years
Standard therapeutic dosage: 20 - 50mg/kg body-weight once daily.
Up to 80mg/kg body-weight daily may be given in severe infections, except in neonates where a daily dosage of 50mg/kg should not be exceeded. For children with body weights of 50 kg or more, the usual adult dosage should be used.
In patients with impaired renal function, there is no need to reduce the dosage of Rocephin provided liver function is intact. Only in cases of pre-terminal renal failure (creatinine clearance < 10ml per minute) should the daily dosage be limited to 2g or less.
In patients with liver damage there is no need for the dosage to be reduced provided renal function is intact.
In severe renal impairment accompanied by hepatic insufficiency, the plasma concentration of Rocephin should be determined at regular intervals in order to ensure that the plasma level is in excess of the minimum inhibitory concentration of the causative organism(s), assuming this is sensitive, and dosage adjusted so that accumulation of Rocephin does not occur.
In patients undergoing dialysis, no additional supplementary dosing is required following the dialysis. Serum concentrations should be monitored, however, to determine whether dosage adjustments are necessary, since the elimination rate in these patients may be reduced.
4.3 Contraindications
Hypersensitivity to ceftriaxone, to any other cephalosporin or to any of the excipients listed in section 6.1.
History of severe hypersensitivity (e.g. anaphylactic reaction) to any other type of beta-lactam antibacterial agent (penicillins, monobactams and carbapenems).
Ceftriaxone is contraindicated in:
Premature neonates up to a postmenstrual age of 41 weeks (gestational age + chronological age)*
Full-term neonates (up to 28 days of age):
- with hyperbilirubinaemia, jaundice, or who are hypoalbuminaemic or acidotic because these are conditions in which bilirubin binding is likely to be impaired*
- if they require (or are expected to require) intravenous calcium treatment, or calcium-containing infusions due to the risk of precipitation of a ceftriaxone-calcium salt (see sections 4.4, 4.8 and 6.2).
* In vitro studies have shown that ceftriaxone can displace bilirubin from its serum albumin binding sites leading to a possible risk of bilirubin encephalopathy in these patients.
Contraindications to lidocaine must be excluded before intramuscular injection of ceftriaxone when lidocaine solution is used as a solvent (see section 4.4). See information in the Summary of Product Characteristics of lidocaine, especially contraindications.
Ceftriaxone solutions containing lidocaine should never be administered intravenously.
Rocephin is contraindicated in patients with known hypersensitivity to beta-lactam antibiotics.
In patients hypersensitive to penicillin, the possibility of allergic cross-reactions should be borne in mind.
Hyperbilirubinaemic newborns and preterm newborns should not be treated with ceftriaxone. In vitro studies have shown that ceftriaxone can displace bilirubin from its binding to serum albumin and bilirubin encephalopathy can possibly develop in these patients.
Ceftriaxone is contraindicated in:
· Premature newborns up to a corrected age of 41 weeks (weeks of gestation + weeks of life),
· Full-term newborns (up to 28 days of age)
· with jaundice, or who are hypoalbuminaemic or acidotic because these are conditions in which bilirubin binding is likely to be impaired
· if they require (or are expected to require) IV calcium treatment, or calcium-containing infusions because of the risk of precipitation of ceftriaxone-calcium (see sections 4.4, 4.8 and 6.2).
Contraindications of lidocaine must be excluded before intramuscular injection of ceftriaxone when lidocaine is used as a solvent.
4.4 Special warnings and precautions for use
Hypersensitivity reactions
As with all beta-lactam antibacterial agents, serious and occasionally fatal hypersensitivity reactions have been reported (see section 4.8). In case of severe hypersensitivity reactions, treatment with ceftriaxone must be discontinued immediately and adequate emergency measures must be initiated. Before beginning treatment, it should be established whether the patient has a history of severe hypersensitivity reactions to ceftriaxone, to other cephalosporins or to any other type of beta-lactam agent. Caution should be used if ceftriaxone is given to patients with a history of non-severe hypersensitivity to other beta-lactam agents.
Severe cutaneous adverse reactions (Stevens Johnson syndrome or Lyell’s syndrome/toxic epidermal necrolysis) have been reported; however, the frequency of these events is not known (see section 4.8).
Interaction with calcium containing products
Cases of fatal reactions with calcium-ceftriaxone precipitates in lungs and kidneys in premature and full-term neonates aged less than 1 month have been described. At least one of them had received ceftriaxone and calcium at different times and through different intravenous lines. In the available scientific data, there are no reports of confirmed intravascular precipitations in patients, other than neonates, treated with ceftriaxone and calcium-containing solutions or any other calcium-containing products. In vitro studies demonstrated that neonates have an increased risk of precipitation of ceftriaxone-calcium compared to other age groups.
In patients of any age ceftriaxone must not be mixed or administered simultaneously with any calcium-containing intravenous solutions, even via different infusion lines or at different infusion sites. However, in patients older than 28 days of age ceftriaxone and calcium-containing solutions may be administered sequentially one after another if infusion lines at different sites are used or if the infusion lines are replaced or thoroughly flushed between infusions with physiological salt-solution to avoid precipitation. In patients requiring continuous infusion with calcium-containing total parenteral nutrition (TPN) solutions, healthcare professionals may wish to consider the use of alternative antibacterial treatments which do not carry a similar risk of precipitation. If the use of ceftriaxone is considered necessary in patients requiring continuous nutrition, TPN solutions and ceftriaxone can be administered simultaneously, albeit via different infusion lines at different sites. Alternatively, infusion of TPN solution could be stopped for the period of ceftriaxone infusion and the infusion lines flushed between solutions (see sections 4.3, 4.8, 5.2 and 6.2).
Paediatric population
Safety and effectiveness of Rocephin in neonates, infants and children have been established for the dosages described under Posology and Method of Administration (see section 4.2). Studies have shown that ceftriaxone, like some other cephalosporins, can displace bilirubin from serum albumin.
Rocephin is contraindicated in premature and full-term neonates at risk of developing bilirubin encephalopathy (see section 4.3).
Immune mediated haemolytic anaemia
An immune mediated haemolytic anaemia has been observed in patients receiving cephalosporin class antibacterials including Rocephin (see section 4.8). Severe cases of haemolytic anaemia, including fatalities, have been reported during Rocephin treatment in both adults and children.
If a patient develops anaemia while on ceftriaxone, the diagnosis of a cephalosporin-associated anaemia should be considered and ceftriaxone discontinued until the aetiology is determined.
Long term treatment
During prolonged treatment complete blood count should be performed at regular intervals.
Colitis/Overgrowth of non-susceptible microorganisms
Antibacterial agent-associated colitis and pseudo-membranous colitis have been reported with nearly all antibacterial agents, including ceftriaxone, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhoea during or subsequent to the administration of ceftriaxone (see section 4.8). Discontinuation of therapy with ceftriaxone and the administration of specific treatment for Clostridium difficile should be considered. Medicinal products that inhibit peristalsis should not be given.
Superinfections with non-susceptible micro-organisms may occur as with other antibacterial agents.
Severe renal and hepatic insufficiency
In severe renal and hepatic insufficiency, close clinical monitoring for safety and efficacy is advised (see section 4.2).
Interference with serological testing
Interference with Coombs tests may occur, as Rocephin may lead to false-positive test results. Rocephin can also lead to false-positive test results for galactosaemia (see section 4.8).
Non-enzymatic methods for the glucose determination in urine may give false-positive results. Urine glucose determination during therapy with Rocephin should be done enzymatically (see section 4.8).
Sodium
Each gram of Rocephin contains 3.6 mmol sodium. This should be taken into consideration in patients on a controlled sodium diet.
Antibacterial spectrum
Ceftriaxone has a limited spectrum of antibacterial activity and may not be suitable for use as a single agent for the treatment of some types of infections unless the pathogen has already been confirmed (see section 4.2). In polymicrobial infections, where suspected pathogens include organisms resistant to ceftriaxone, administration of an additional antibiotic should be considered.
Use of lidocaine
In case a lidocaine solution is used as a solvent, ceftriaxone solutions must only be used for intramuscular injection. Contraindications to lidocaine, warnings and other relevant information as detailed in the Summary of Product Characteristics of lidocaine must be considered before use (see section 4.3). The lidocaine solution should never be administered intravenously.
Biliary lithiasis
When shadows are observed on sonograms, consideration should be given to the possibility of precipitates of calcium ceftriaxone. Shadows, which have been mistaken for gallstones, have been detected on sonograms of the gallbladder and have been observed more frequently at ceftriaxone doses of 1 g per day and above. Caution should be particularly considered in the paediatric population. Such precipitates disappear after discontinuation of ceftriaxone therapy. Rarely precipitates of calcium ceftriaxone have been associated with symptoms. In symptomatic cases, conservative nonsurgical management is recommended and discontinuation of ceftriaxone treatment should be considered by the physician based on specific benefit risk assessment (see section 4.8).
Biliary stasis
Cases of pancreatitis, possibly of biliary obstruction aetiology, have been reported in patients treated with Rocephin (see section 4.8). Most patients presented with risk factors for biliary stasis and biliary sludge e.g. preceding major therapy, severe illness and total parenteral nutrition. A trigger or cofactor of Rocephin-related biliary precipitation cannot be ruled out.
Renal lithiasis
Cases of renal lithiasis have been reported, which is reversible upon discontinuation of ceftriaxone (see section 4.8). In symptomatic cases, sonography should be performed. Use in patients with history of renal lithiasis or with hypercalciuria should be considered by the physician based on specific benefit risk assessment.
The stated dosage should not be exceeded.
As with other cephalosporins, anaphylactic reactions with fatal outcome were also reported, even if a patient is not known to be allergic or previously exposed.
Before therapy with ceftriaxone is instituted, careful inquiry should be made to determine whether the patient has had any previous hypersensitivity reactions to ceftriaxone, any other cephalosporin, or to any penicillin or other beta-lactam drug. Ceftriaxone is contraindicated in patients who have had a previous hypersensitivity reaction to any cephalosporin. It is also contraindicated in patients who have had a previous immediate and/or any severe hypersensitivity reaction to any penicillin or to any other beta lactam drug. Ceftriaxone should be given with caution to patients who have had any other type of hypersensitivity reaction to a penicillin or any other beta-lactam drug.
Ceftriaxone should be given with caution to patients who have other allergic diatheses.
In severe renal impairment accompanied by hepatic insufficiency, dosage reduction is required as outlined under section 4.2.
An immune mediated haemolytic anaemia has been observed in patients receiving cephalosporin class antibacterials including Rocephin. Severe cases of haemolytic anaemia, including fatalities, have been reported during treatment in both adults and children. If a patient develops anaemia while on ceftriaxone, the diagnosis of a cephalosporin associated anaemia should be considered and ceftriaxone discontinued until the aetiology is determined.
Clostridium difficile associated diarrhoea (CDAD) has been reported with use of nearly all antibacterial agents, including Rocephin, and may range in severity from mild diarrhoea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.
C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhoea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.
If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.
Superinfections with non-susceptible micro-organisms may occur as with other antibacterial agents.
Pseudomembranous colitis has been reported with nearly all antibacterial agents, including ceftriaxone. Therefore, it is important to consider this diagnosis in patients who present with diarrhoea subsequent to administration of antibacterial agents (see section 4.8).
As with other cephalosporins, prolonged use of ceftriaxone may result in the overgrowth of non-susceptible organisms, such as enterococci and Candida spp.
Interaction with Calcium-Containing Products
Cases of fatal reactions with calcium-ceftriaxone precipitates in lungs and kidneys in premature and full-term newborns aged less than 1 month have been described. At least one of them had received ceftriaxone and calcium at different times and through different intravenous lines. In the available scientific data, there are no reports of confirmed intravascular precipitations in patients, other than newborns, treated with ceftriaxone and calcium-containing solutions or any other calcium-containing products. In vitro studies demonstrated that newborns have an increased risk of precipitation of ceftriaxone-calcium compared to other age groups.
In patients of any age ceftriaxone must not be mixed or administered simultaneously with any calcium-containing IV solutions, even via different infusion lines or at different infusion sites. However, in patients older than 28 days of age ceftriaxone and calcium-containing solutions may be administered sequentially one after another if infusion lines at different sites are used, or if the infusion lines are replaced or thoroughly flushed between infusions with physiological salt-solution to avoid precipitation. In patients requiring continuous infusion with calcium-containing TPN solutions, healthcare professionals may wish to consider the use of alternative antibacterial treatments which do not carry a similar risk of precipitation. If use of ceftriaxone is considered necessary in patients requiring continuous nutrition, TPN solutions and ceftriaxone can be administered simultaneously, albeit via different infusion lines at different sites. Alternatively, infusion of TPN solution could be stopped for the period of ceftriaxone infusion, considering the advice to flush infusion lines between solutions. (See sections 4.3, 4.8, 5.2 and 6.2).
Shadows which have been mistaken for gallstones have been detected by sonograms of the gallbladder, usually following doses higher than the standard recommended dose. These shadows are, however, precipitates of calcium ceftriaxone which disappear on completion or discontinuation of Rocephin therapy. Rarely, have these findings been associated with symptoms. In symptomatic cases, conservative non-surgical management is recommended. Discontinuation of Rocephin treatment in symptomatic cases should be at the discretion of the clinician (see section 4.8).
Cases of pancreatitis, possibly of biliary obstruction aetiology, have been rarely reported in patients treated with Rocephin. Most patients presented with risk factors for biliary stasis and biliary sludge, e.g. preceding major therapy, severe illness and total parenteral nutrition. A trigger or cofactor role of Rocephin-related biliary precipitation cannot be ruled out.
Safety and effectiveness of Rocephin in neonates, infants and children have been established for the dosages in section 4.2.
During prolonged treatment, the blood cell count should be checked regularly.
Each gram of Rocephin contains approximately 3.6mmol sodium. To be taken into consideration by patients on a controlled sodium diet.
For intramuscular injection, only the lidocaine solvent provided should be used.
4.5 Interaction with other medicinal products and other forms of interaction
Calcium-containing diluents, such as Ringer’s solution or Hartmann’s solution, should not be used to reconstitute Rocephin vials or to further dilute a reconstituted vial for intravenous administration because a precipitate can form. Precipitation of ceftriaxone-calcium can also occur when ceftriaxone is mixed with calcium-containing solutions in the same intravenous administration line. Ceftriaxone must not be administered simultaneously with calcium-containing intravenous solutions, including continuous calcium-containing infusions such as parenteral nutrition via a Y-site. However, in patients other than neonates, ceftriaxone and calcium-containing solutions may be administered sequentially of one another if the infusion lines are thoroughly flushed between infusions with a compatible fluid. In vitro studies using adult and neonatal plasma from umbilical cord blood demonstrated that neonates have an increased risk of precipitation of ceftriaxone-calcium (see sections 4.2, 4.3, 4.4, 4.8 and 6.2).
Concomitant use with oral anticoagulants may increase the anti-vitamin K effect and the risk of bleeding. It is recommended that the International Normalised Ratio (INR) is monitored frequently and the posology of the anti-vitamin K drug adjusted accordingly, both during and after treatment with ceftriaxone (see section 4.8).
There is conflicting evidence regarding a potential increase in renal toxicity of aminoglycosides when used with cephalosporins. The recommended monitoring of aminoglycoside levels (and renal function) in clinical practice should be closely adhered to in such cases.
In an in-vitro study antagonistic effects have been observed with the combination of chloramphenicol and ceftriaxone. The clinical relevance of this finding is unknown.
There have been no reports of an interaction between ceftriaxone and oral calcium-containing products or interaction between intramuscular ceftriaxone and calcium-containing products (intravenous or oral).
In patients treated with ceftriaxone, the Coombs' test may lead to false-positive test results.
Ceftriaxone, like other antibiotics, may result in false-positive tests for galactosaemia.
Likewise, non-enzymatic methods for glucose determination in urine may yield false-positive results. For this reason, glucose level determination in urine during therapy with ceftriaxone should be carried out enzymatically.
No impairment of renal function has been observed after concurrent administration of large doses of ceftriaxone and potent diuretics (e.g. furosemide).
Simultaneous administration of probenecid does not reduce the elimination of ceftriaxone.
No impairment of renal function has so far been observed after concurrent administration of large doses of Rocephin and potent diuretics (e.g. furosemide).
No interference with the action or increase in nephrotoxicity of aminoglycosides has been observed during simultaneous administration with Rocephin.
No effect similar to that of disulfiram has been demonstrated after ingestion of alcohol subsequent to the administration of Rocephin. Ceftriaxone does not contain an N-methylthiotetrazole moiety associated with possible ethanol intolerance and bleeding problems of certain other cephalosporins.
Simultaneous administration of probenecid does not reduce the elimination of Rocephin and its use with Rocephin is not indicated.
In vitro, chloramphenicol has been shown to be antagonistic with respect to ceftriaxone and other cephalosporins. The clinical relevance of this finding is unknown, but caution is advised if concurrent administration of ceftriaxone with chloramphenicol is proposed.
Based on literature reports ceftriaxone is incompatible with amsacrine, vancomycin, fluconazole and aminoglycosides (see section 6.2).
In patients treated with Rocephin, the Coombs’ test may rarely become false-positive. Rocephin, like other antibiotics, may result in false-positive tests for galactosaemia. Likewise, non-enzymatic methods for glucose determination in urine may give false-positive results. For this reason, urine-glucose determination during therapy with Rocephin should be done enzymatically.
Ceftriaxone may adversely affect the efficacy of oral hormonal contraceptives. Consequently, it is advisable to use supplementary (non-hormonal) contraceptive measures during treatment and in the month following treatment.
4.6 Fertility, Ppregnancy and lactation
Pregnancy
Ceftriaxone crosses the placental barrier. There are limited amounts of data from the use of ceftriaxone in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to embryonal/foetal, perinatal and postnatal development (see section 5.3). Ceftriaxone should only be administered during pregnancy and in particular in the first trimester of pregnancy if the benefit outweighs the risk.
Breastfeeding
Ceftriaxone is excreted into human milk in low concentrations but at therapeutic doses of ceftriaxone no effects on the breastfed infants are anticipated. However, a risk of diarrhoea and fungal infection of the mucous membranes cannot be excluded. The possibility of sensitisation should be taken into account. A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from ceftriaxone therapy, taking into account the benefit of breast feeding for the child and the benefit of therapy for the woman.
Fertility
Reproductive studies have shown no evidence of adverse effects on male or female fertility.
Pregnancy
For ceftriaxone limited clinical data on exposed pregnancies are available. Ceftriaxone crosses the placental barrier. Reproductive studies in animals have shown no evidence of embryotoxicity, foetotoxicity, teratogenicity or adverse effects on male or female fertility, birth or perinatal and postnatal development. In primates, no embryotoxicity or teratogenicity has been observed. Since safety in human pregnancy is not established ceftriaxone should not be used unless absolutely indicated.
Lactation
Low concentrations of ceftriaxone are excreted in human milk. Caution should be exercised when ceftriaxone is administered to a nursing woman.
4.7 Effects on ability to drive and use machines
During treatment with ceftriaxone, undesirable effects may occur (e.g. dizziness), which may influence the ability to drive and use machines (see section 4.8). Patients should be cautious when driving or operating machinery.
Since Rocephin sometimes induces dizziness the ability to drive and use machines can be impaired.
4.8 Undesirable Eeffects
The most frequently reported adverse reactions for ceftriaxone are eosinophilia, leucopenia, thrombocytopenia, diarrhoea, rash, and hepatic enzymes increased.
Data to determine the frequency of ceftriaxone ADRs was derived from clinical trials.
The following convention has been used for the classification of frequency:
Very common (≥ 1/10)
Common (≥ 1/100 ‑ < 1/10)
Uncommon (≥ 1/1000 ‑ < 1/100)

a Based on post-marketing reports. Since these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency which is therefore categorised as not known.
b See section 4.4
Infections and infestations
Reports of diarrhoea following the use of ceftriaxone may be associated with Clostridium difficile. Appropriate fluid and electrolyte management should be instituted (see section 4.4).
Ceftriaxone-calcium salt precipitation
Rarely, severe, and in some cases, fatal, adverse reactions have been reported in pre-term and full-term neonates (aged < 28 days) who had been treated with intravenous ceftriaxone and calcium. Precipitations of ceftriaxone-calcium salt have been observed in lung and kidneys post-mortem. The high risk of precipitation in neonates is a result of their low blood volume and the longer half-life of ceftriaxone compared with adults (see sections 4.3, 4.4, and 5.2).
Cases of renal precipitation have been reported, primarily in children older than 3 years of age and who have been treated with either high daily doses (e.g. ³ 80 mg/kg/day) or total doses exceeding 10 grams and who presented with other risk factors (e.g. fluid restrictions or confinement to bed). The risk of precipitate formation is increased in immobilized or dehydrated patients. This event may be symptomatic or asymptomatic, may lead to renal insufficiency and anuria, and is reversible upon discontinuation of ceftriaxone (see section 4.4).
Precipitation of ceftriaxone calcium salt in the gallbladder has been observed, primarily in patients treated with doses higher than the recommended standard dose. In children, prospective studies have shown a variable incidence of precipitation with intravenous application - above 30 % in some studies. The incidence appears to be lower with slow infusion (20 - 30 minutes). This effect is usually asymptomatic, but the precipitations have been accompanied by clinical symptoms such as pain, nausea and vomiting in rare cases. Symptomatic treatment is recommended in these cases. Precipitation is usually reversible upon discontinuation of ceftriaxone (see section 4.4).
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via HPRA Pharmacovigilance,

Rarely severe adverse reactions have been reported in preterm and full-term newborns (aged <28 days). These reactions have caused death in some cases. These newborns had been treated with intravenous ceftriaxone and calcium. Some of them had received ceftriaxone and calcium at different times and on different intravenous lines. Precipitations of ceftriaxone – calcium salt have been observed in lungs and kidneys of these dead preterm newborns. The high risk of precipitation is due to the low blood volume of the newborns. Moreover the half life is longer than in adults (see sections 4.3, 4.4 and 5.2).
The most frequently reported adverse events for ceftriaxone are diarrhoea, nausea and vomiting. Other reported adverse events include hypersensitivity reactions such as allergic skin reactions and anaphylactic reactions, secondary infections with yeast, fungi or resistant organisms as well as changes in blood cell counts.
Infections and infestations
Rare (³ 0.01 % - < 0.1 %): Mycosis of the genital tract.
Superinfections of various sites with yeasts, fungi or other resistant microorganisms are possible.
Pseudomembraneous colitis is a rare undesirable effect caused by infection with Clostridium difficile during treatment with Rocephin. Therefore, the possibility of the disease should be considered in patients who present with diarrhoea following antibacterial agent use (see section 4.4).
Blood and lymphatic system disorders
Rare (³ 0.01 % - < 0.1 %): Neutropenia, leucopenia, eosinophilia, thrombocytopenia, anaemia (including haemolytic anaemia), slight prolongation of prothrombin time.
Very rare (< 0.01 %) including isolated reports: Positive Coombs’ test, coagulation disorders, agranulocytosis (< 500/m3), mostly after 10 days of treatment and following total doses of 20g ceftriaxone and more.
Immune system disorders
Rare (³ 0.01 % - < 0.1 %): Anaphylactic (e.g. bronchospasm) and anaphylactoid reactions (see section 4.4).
Nervous system disorders
Rare (³ 0.01 % - < 0.1 %): Headache, dizziness.
Gastrointestinal disorders
Common (³ 1% - < 10%): Loose stools or diarrhoea, nausea, vomiting.
Rare (³ 0.01 % - < 0.1 %): Stomatitis, glossitis. These side effects are usually mild and commonly disappear during treatment or after discontinuation of treatment.
Very rare (< 0.01 %) including isolated reports: Pseudomembranous colitis (mostly caused by Clostridium difficile), pancreatitis (possibly caused by obstruction of bile ducts).
Hepato-biliary disorders
Rare (³ 0.01 % - < 0.1 %): Increase in serum liver enzymes (AST, ALT, alkaline phosphatase), jaundice.
Precipitation of ceftriaxone calcium salt in the gallbladder has been observed (see section 4.4), mostly in patients treated with doses higher than the recommended standard dose. In children, prospective studies have shown a variable incidence of precipitation with intravenous application, in some studies to above 30%. The incidence seems to be lower with slow infusion (20-30 minutes). This effect is usually asymptomatic, but in rare cases, the precipitations have been accompanied by clinical symptoms such as pain, nausea and vomiting. Symptomatic treatment is recommended in these cases. Precipitation is usually reversible upon discontinuation of ceftriaxone.
Skin and subcutaneous tissue disorders
Uncommon (³ 0.1 % - < 1 %): Allergic skin reactions such as maculopapular rash or exanthema, urticaria, dermatitis, pruritis, oedema.
Very rare (< 0.01 %) including isolated reports: Erythema multiforme, Stevens Johnson Syndrome, Lyell’s Syndrome/toxic epidermal necrolysis.
Renal and urinary disorders
Rare (³ 0.01 % - < 0.1 %): Increase in serum creatinine, oliguria, glycosuria, haematuria.
Very rare (< 0.01 %) including isolated reports: Renal precipitation, mostly in children older than 3 years who have been treated with either high daily doses (e.g. ≥ 80 mg/kg/day) or total doses exceeding 10g and with other risk factors such as dehydration or immobilisation. Renal precipitation is reversible upon discontinuation of ceftriaxone. Anuria and renal impairment have been reported in association.
General disorders and administration site conditions
Rare (³ 0.01 % - < 0.1 %): Phlebitis and injection site pain following intravenous administration. This can be minimised by slow injection over at least 2-4 minutes. Rigors, pyrexia.
An intramuscular injection without lidocaine solution is painful.
4.9 Overdosage
In overdose, the symptoms of nausea, vomiting and diarrhoea can occur. Ceftriaxone concentrations cannot be reduced by haemodialysis or peritoneal dialysis. There is no specific antidote. Treatment of overdose should be symptomatic.
In the case of overdosage, nausea, vomiting, diarrhoea can occur. Ceftriaxone concentrations would not be reduced by haemodialysis or peritoneal dialysis. There is no specific antidote. Treatment should be symptomatic.
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antibacterials for systemic use, Third-generation cephalosporins, ATC code: J01DD04.
Mode of action
Ceftriaxone inhibits bacterial cell wall synthesis following attachment to penicillin binding proteins (PBPs). This results in the interruption of cell wall (peptidoglycan) biosynthesis, which leads to bacterial cell lysis and death.
Resistance
Bacterial resistance to ceftriaxone may be due to one or more of the following mechanisms:
· hydrolysis by beta-lactamases, including extended-spectrum beta-lactamases (ESBLs), carbapenemases and Amp C enzymes that may be induced or stably derepressed in certain aerobic Gram-negative bacterial species.
· reduced affinity of penicillin-binding proteins for ceftriaxone.
· outer membrane impermeability in Gram-negative organisms.
· bacterial efflux pumps.

Clinical efficacy against specific pathogens
The prevalence of acquired resistance may vary geographically and with time for selected species and local information on resistance is desirable, particularly when treating severe infections. As necessary, expert advice should be sought when the local prevalence of resistance is such that the utility of ceftriaxone in at least some types of infections is questionable.

Ceftriaxone is a long-acting, broad spectrum cephalosporin antibiotic for parenteral use.
The bactericidal activity of ceftriaxone results from inhibition of cell wall synthesis. Ceftriaxone exerts in vitro activity against a wide range of Gram-negative and Gram-positive organisms including both aerobic and anaerobic species. Ceftriaxone is highly stable to most beta-lactamases, both penicillinases and cephalosporinases, of Gram-positive and Gram-negative bacteria.
The outstanding feature of Rocephin is its relatively long plasma elimination half-life of approximately 8 hours, which makes single or once-daily dosage of the drug appropriate for most patients.
Microbiology
Ceftriaxone is usually active against the following micro-organisms in vitro and in clinical infections (see section 4.1). The list is not exhaustive and focuses on those organisms of particular clinical interest.
Gram-positive aerobes
Staphylococcus aureus (including penicillinase-producing strains)
Staphylococcus epidermidis
Streptococcus pneumoniae
Streptococcus group A (Streptococcus pyogenes)
Streptococcus group B (Streptococcus agalactiae)
Streptococcus viridans
Streptococcus bovis
Note
Methicillin-resistant Staphylococcus spp. are resistant to cephalosporins, including ceftriaxone. In general, Enterococcus faecalis, Enterococcus faecium and Listeria monocytogenes are resistant.
Gram-negative aerobes
Aeromonas spp.
Alcaligenes spp.
Moraxella catarrhalis (beta-lactamase negative and positive)
Citrobacter spp.
Enterobacter spp. (some strains are resistant)
Escherichia coli
Haemophilus ducreyi
Haemophilus influenzae (including penicillinase-producing strains)
Haemophilus parainfluenzae
Klebsiella spp. (including K. pneumoniae)
Moraxella spp.
Morganella morganii (= Proteus morganii)
Neisseria gonorrhoeae (including penicillinase-producing strains)
Neisseria meningitidis
Plesiomonas shigelloides
Proteus mirabilis
Proteus vulgaris
Providencia spp.
Pseudomonas spp. (some strains are resistant)
Salmonella spp. (including S. typhi)
Serratia spp. (including S. marcescens)
Shigella spp.
Vibrio spp. (including V. cholerae)
Yersinia spp. (including Y. enterocolitica)
Note
Many strains of the above organisms that are multiply resistant to other antibiotics, e.g. penicillins, older cephalosporins and aminoglycosides, are susceptible to ceftriaxone. Treponema pallidum is sensitive in vitro and in animal experiments. Clinical investigations indicate that primary and secondary syphilis respond well to ceftriaxone therapy. With a few exceptions clinical P. aeruginosa isolates are resistant to ceftriaxone.
Synergy between Rocephin and aminoglycosides has been demonstrated with many Gram-negative bacilli under experimental conditions. Although enhanced activity of such combinations is not always predictable, it should be considered in severe, life-threatening infections due to organisms such as Pseudomonas aeruginosa. Because of physical incompatibility the two drugs must be administered separately at the recommended dosages.
Anaerobic organisms
Bacteroides spp. (many strains notably B. fragilis are resistant)
Clostridium spp. (except C. difficile)
Fusobacterium spp. (except F. mortiferum and F. varium)
Gaffkia anaerobica (formerly peptococcus)
Peptostreptococcus spp.
Susceptibility to ceftriaxone can be determined by the disc diffusion test or by the agar or broth dilution test using standardised techniques for susceptibility testing such as those recommended by the National Committee for Clinical Laboratory Standards (NCCLS). The NCCLS issued the following interpretative breakpoints for ceftriaxone:
Dilution susceptibility testing: Susceptible £ 8mg/litre; moderately susceptible 16 - 32mg/litre; resistant ≥ 64mg/litre.
Diffusion susceptibility testing using a 30 microgram ceftriaxone disc: Susceptible ≥ 21mm; moderately susceptible 20 - 14mm; resistant £ 13mm.
Organisms should be tested with the ceftriaxone disc since it has been shown by in vitro tests to be active against certain strains resistant to cephalosporin class discs.
Where NCCLS recommendations are not in daily use, alternative, well standardised, susceptibility interpretative guidelines such as those issued by DIN, ICS and others may be substituted.
5.2 Pharmacokinetic properties
Absorption
After intravenous bolus administration of ceftriaxone 500 mg and 1 g, mean peak plasma ceftriaxone levels are approximately 120 and 200 mg/l respectively. After intravenous infusion of ceftriaxone 500 mg, 1 g and 2 g, the plasma ceftriaxone levels are approximately 80, 150 and 250 mg/l respectively. Following intramuscular injection, mean peak plasma ceftriaxone levels are approximately half those observed after intravenous administration of an equivalent dose. The maximum plasma concentration after a single intramuscular dose of 1 g is about 81 mg/l and is reached in 2 - 3 hours after administration.
The area under the plasma concentration-time curve after intramuscular administration is equivalent to that after intravenous administration of an equivalent dose.
Distribution
The volume of distribution of ceftriaxone is 7 – 12 l. Concentrations well above the minimal inhibitory concentrations of most relevant pathogens are detectable in tissue including lung, heart, biliary tract/liver, tonsil, middle ear and nasal mucosa, bone, and in cerebrospinal, pleural, prostatic and synovial fluids. An 8 - 15 % increase in mean peak plasma concentration (Cmax) is seen on repeated administration; steady state is reached in most cases within 48 - 72 hours depending on the route of administration.
Penetration into particular tissues
Ceftriaxone penetrates the meninges. Penetration is greatest when the meninges are inflamed. Mean peak ceftriaxone concentrations in CSF in patients with bacterial meningitis are reported to be up to 25 % of plasma levels compared to 2 % of plasma levels in patients with uninflamed meninges. Peak ceftriaxone concentrations in CSF are reached approximately 4‑6 hours after intravenous injection. Ceftriaxone crosses the placental barrier and is excreted in the breast milk at low concentrations (see section 4.6).
Protein binding
Ceftriaxone is reversibly bound to albumin. Plasma protein binding is about 95 % at plasma concentrations below 100 mg/l. Binding is saturable and the bound portion decreases with rising concentration (up to 85 % at a plasma concentration of 300 mg/l).
Biotransformation
Ceftriaxone is not metabolised systemically; but is converted to inactive metabolites by the gut flora.
Elimination
Plasma clearance of total ceftriaxone (bound and unbound) is 10 - 22 ml/min. Renal clearance is 5 - 12 ml/min. 50 - 60 % of ceftriaxone is excreted unchanged in the urine, primarily by glomerular filtration, while 40 - 50 % is excreted unchanged in the bile. The elimination half-life of total ceftriaxone in adults is about 8 hours.
Patients with renal or hepatic impairment
In patients with renal or hepatic dysfunction, the pharmacokinetics of ceftriaxone are only minimally altered with the half-life slightly increased (less than two fold), even in patients with severely impaired renal function.
The relatively modest increase in half-life in renal impairment is explained by a compensatory increase in non-renal clearance, resulting from a decrease in protein binding and corresponding increase in non-renal clearance of total ceftriaxone.
In patients with hepatic impairment, the elimination half-life of ceftriaxone is not increased, due to a compensatory increase in renal clearance. This is also due to an increase in plasma free fraction of ceftriaxone contributing to the observed paradoxical increase in total drug clearance, with an increase in volume of distribution paralleling that of total clearance.
