Mupirocin is a topical antibiotic used to treat skin infections caused by certain bacteria. It works by inhibiting bacterial protein synthesis, effectively stopping the growth of the bacteria. Commonly prescribed for conditions like impetigo and folliculitis, it is applied directly to the affected area. This medication is available in ointment and cream forms and is typically used two to three times a day. While generally safe, some people may experience mild side effects such as itching or burning at the application site. It is important to use Mupirocin as directed by a healthcare professional.
