Mupirocin is a topical antibiotic medication used to treat bacterial skin infections such as impetigo and to eliminate nasal carriage of certain bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). It works by inhibiting bacterial protein synthesis, effectively stopping the growth of susceptible bacteria.

Mupirocin is primarily used to treat impetigo and other minor skin infections caused by Staphylococcus aureus and Streptococcus pyogenes. It is also available as a nasal ointment for eradication of nasal MRSA colonization in healthcare settings.
Mupirocin inhibits bacterial RNA synthetase (specifically isoleucyl-tRNA synthetase), which prevents the incorporation of isoleucine into bacterial proteins. This inhibition of protein synthesis is bactericidal against susceptible organisms.
For topical use only; avoid contact with eyes. The nasal ointment should not be used alongside other nasal products. Resistance may develop with prolonged use. Apply a small amount to the affected area 2-3 times daily as directed. Discontinue if sensitization or severe irritation occurs.
