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, mupirocin is usually 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, as directed by a healthcare provider. While mupirocin is effective for many skin infections, it is important to use it only as prescribed to avoid antibiotic resistance.
