Mupirocin, sold under the brand name Bactroban among others, is a topical antibiotic useful against superficial skin infections such as impetigo or folliculitis.[5][6][7] It may also be used to get rid of methicillin-resistant S. aureus (MRSA) when present in the nose without symptoms.[6] Due to concerns of developing resistance, use for greater than ten days is not recommended.[7] It is used as a cream or ointment applied to the skin.[6]

Common side effects include itchiness and rash at the site of application, headache, and nausea.[6] Long term use may result in increased growth of fungi.[6] Use during pregnancy and breastfeeding appears to be safe.[6] Mupirocin is chemically a carboxylic acid.[8] It works by blocking a bacteria's ability to make protein, which usually results in bacterial death.[6]

Mupirocin was initially isolated in 1971 from Pseudomonas fluorescens.[9] It is on the World Health Organization's List of Essential Medicines.[10] In 2021, it was the 203rd most commonly prescribed medication in the United States, with more than 2 million prescriptions.[11][12] It is available as a generic medication.[13]
