Mupirocin, sold under the brand name Bactroban among others, is a topical antibiotic useful against superficial skin infections such as impetigo or folliculitis. It may also be used to get rid of methicillin-resistant S. aureus (MRSA) when present in the nose without symptoms. Out of concerns of developing resistance, use for greater than ten days is not recommended. It is used as a cream or ointment applied to the skin.
