Mupirocin, is an 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.
Due to 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.
Common side effects include itchiness and rash at the site of application, headache, and nausea.
Long term use may result in increased growth of fungi. Use during pregnancy and breastfeeding appear to be safe. Mupirocin is in the carbolic acid class of medications.
It works by blocking the making of protein by the bacteria which usually results in bacterial death.
