Fucidin Suspension

In the treatment of systemic infections due to micro-organisms sensitive to this anti-infective, such as Staphylococci.

Posology

Adult dose: The usual total daily dose is 1500-2000 mg (30 – 40 ml) each day in 3 equally divided doses.

Paediatric population

Children: The usual daily dose is 20-50 mg/kg (0.4 ml/kg – 1 ml/kg) each day in 3 equally divided doses.

Method of administration

For oral administration. The suspension should be shaken well before use.

Hypersensitivity to the active substance or to any of the excipients.

Concomitant treatment with statins (HMG-CoA reductase inhibitors). (See section 4.4, 4.5).

This medicinal product contains 1.6 mg sodium per ml suspension. To be taken into consideration by patients on a controlled sodium diet.

Statins (HMG-CoA reductase inhibitors) and systemic Fucidin must not be co-administered, (see section 4.3). There have been reports of rhabdomyolysis (including fatalities) in patients receiving this combination. Statin treatment should be discontinued throughout the duration of treatment with systemic Fucidin. The patient should be advised to seek medical advice immediately if they experience any symptoms of muscle weakness, pain or tenderness. Statin therapy may be re-introduced 7 days after the last dose of systemic Fucidin.

In exceptional circumstances, where prolonged systemic Fucidin is needed, e.g. for the treatment of severe infections, the need for co-administration of HMG-CoA reductase inhibitors and systemic Fucidin should only be considered on a case by case basis and under close medical supervision.

In a few cases, serious cutaneous reactions putting life at risk such as Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome, toxic epidermal necrolysis (Lyell's syndrome) and Stevens-Johnson syndrome have been reported with systemic Fucidin. Patients should be advised to monitor cutaneous reactions as well as signs and symptoms suggestive of these reactions which usually appear in the first weeks of therapy. If such reactions are suspected to be due to systemic Fucidin, treatment with systemic Fucidin should be stopped and it is recommended not to reintroduce the therapy.

Fusidic acid is metabolised in the liver and excreted in the bile. Elevated liver enzymes and jaundice have occurred during systemic Fucidin therapy but are usually reversible on discontinuation of the drug.

Systemic Fucidin should be given with caution and liver function should be monitored if used in patients with hepatic dysfunction. Caution is required in patients with biliary disease and biliary tract obstruction. Caution is required in patients treated with HIV-protease inhibitors (see section 4.5). Fusidic acid competitively inhibits binding of bilirubin to albumin. Caution is necessary if systemic Fucidin is administered to patients with impaired transport and metabolism of bilirubin. Particular care is advised in neonates due to the theoretical risk of kernicterus.

Bacterial resistance has been reported to occur with the use of fusidic acid. As with all antibiotics, extended or recurrent use may increase the risk of developing antibiotic resistance.

Patients with rare hereditary problems of fructose intolerance should not take this medicine due to its content of sorbitol (E420).

Patients with rare glucose-galactose malabsorption should not take this medicine due to its content of glucose.

This medicinal product contains 1.6 mg sodium per ml suspension. To be taken into consideration by patients on a controlled sodium diet.

Statins (HMG-CoA reductase inhibitors)

Concomitant treatment with statins (HMG-CoA reductase inhibitors) is contraindicated.

Co-administration of systemic Fucidin and statins may cause possibly fatal rhabdomyolysis. Treatment with statins should therefore be discontinued throughout the duration of the treatment with systemic Fucidin. Statin therapy may be reintroduced 7 days after the last dose of systemic Fucidin (See section 4.3 and 4.4.)

Oral anticoagulants

Systemic Fucidin administered concomitantly with oral anticoagulants such as coumarin derivatives or anticoagulants with similar actions may alter the anticoagulant effect. Adjustment of the oral anticoagulant dose may be necessary in order to maintain the desired level of anticoagulation.

HIV protease inhibitors

Co-administration of systemic Fucidin and HIV protease inhibitors such as ritonavir and saquinavir may cause increased plasma concentrations of both agents which may result in hepatotoxicity.

Concomitant use is not recommended. (See section 4.4).

Pregnancy

There are no or limited data (less than 300 pregnancy outcomes) from the use of fusidic acid in pregnant women. Animal studies do not indicate direct or indirect harmful effect with respect to reproductive toxicity. As a precautionary measure, it is preferable to avoid the use of systemic Fucidin during pregnancy.

Breast-feeding

Physico-chemical data suggest excretion of fusidic acid in human milk. A risk to the suckling child cannot be excluded. A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from systemic Fucidin therapy taking into account the benefit of breast-feeding for the child and the benefit of therapy for the woman.

Fertility

There are no clinical studies with systemic Fucidin regarding fertility. Pre-clinical studies did not show any effect of sodium fusidate on the fertility in rats.

Fucidin has no or negligible influence on the ability to drive or to use machines.

The estimation of the frequency of undesirable effects is based on a pooled analysis of data from clinical trials and from spontaneous reporting.

The most frequently reported undesirable effects of Fucidin administered orally are gastrointestinal disorders like abdominal discomfort and pain, diarrhoea, dyspepsia, nausea and vomiting. Anaphylactic shock has been reported.

Undesirable effects are listed by MedDRA SOC and the individual undesirable effects are listed starting with the most frequently reported. Within each frequency group, adverse reactions are presented in the order of decreasing seriousness.

a) Haematological disorders affecting the white cell line (neutropenia, granulocytopenia and agranulocytosis) have been reported

b) Hepatitis also includes hepatitis cholestatic/cytolytic hepatitis

c) Jaundice also includes jaundice cholestatic

d) Including alanine aminotransferase increased, aspartate aminotransferase increased, blood alkaline phosphatase increased, blood bilirubin increased and gamma-glutamyltransferase increased

e) Rash includes various types of rash reactions such as drug eruption, erythematous and maculo-papular rash

f) These adverse reactions were identified through post-marketing surveillance. Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency (see section 4.4).

g) Rhabdomyolysis may be fatal

h) Renal failure also includes renal failure acute

Paediatric population

Frequency, type and severity of adverse reactions in children are expected to be the same as in adults, based on limited data.

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, Earlsfort Terrace, IRL- Dublin 2; Tel: +353 1 6764971; Fax: +353 1 6762517. Website: www.hpra.ie, E-mail: medsafety@hpra.ie

Acute symptoms of overdose include gastrointestinal disturbances. Management should be directed towards alleviation of symptoms. Dialysis will not increase the clearance of fusidic acid.

An overdose of 4 g/day for a duration of 10 days in an adult has been reported without any adverse events.

An overdose of 1,250 mg/day for a duration of 7 days in a child (3 years old) has been reported without any adverse events.

Pharmacotherapeutic group: Steroid antibacterials, ATC code: J01XC01

Fucidin exerts powerful activity against a number of gram-positive organisms. Staphylococci, including the strains resistant to penicillin and other antibiotics, are particularly susceptible to Fucidin. Concentrations of 0.03-0.12 mcg/ml inhibit nearly all strains of Staphylococcus aureus.

Fucidin readily penetrates the central nervous system when the meninges are inflamed and is widely distributed in the body. Bactericidal levels have been assayed in bone and necrotic tissue. Blood levels are cumulative, reaching concentrations of 50-100 mcg/ml after oral administration of 1.5 g daily for 3 to 4 days. Fucidin is excreted mainly in the bile, little or none being excreted in the urine.

There are no preclinical data of relevance to the prescriber which are additional to that already included in other areas of the SPC.
