Fusidic acid, sold under the brand name Fucidin among others, is a steroid antibiotic that is often used topically in creams or ointments and eyedrops but may also be given systemically as tablets or injections. As of October 2008, the global problem of advancing antimicrobial resistance has led to a renewed interest in its use.
