    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 resistance.

    Serious cutaneous reactions such as drug reaction with eosinophilia and systemic symptoms syndrome (DRESS), toxic epidermal necrolysis and Steven-Johnson syndrome have occurred with systemic sodium fusidate treatment. Patients should monitor for signs and symptoms of serious cutaneous reactions, which usually occur in first week of therapy.

    Permanently discontinue if systemic sodium fusidate serious cutaneous reactions occur.

    Pregnancy and Lactation


    Sodium fusidate should be used with caution in pregnancy.

    Sodium fusidate may only be used during pregnancy if the potential benefits outweigh the potential risks to the foetus.

    At the time of writing there was inadequate evidence regarding use during human pregnancy. Animal studies plus many years of clinical experience suggest that there are no teratogenic effects. Fusidic acid is believed to cross the placental barrier when fusidic acid is administered systemically.

    The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame. Further advice may be available from the UK National Teratology Information Service (NTIS) and through ToxBase, available via password on the internet ( ) or if this is unavailable at the backup site ( ).


    Sodium fusidate should be used with caution in breastfeeding.

    Safety has not been established, although levels have been detected in breast milk when fusidic acid (as the sodium salt) has been administered systemically.

    Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
