How long should mupirocin ointment be used for bacterial infection on skin?

5 Days: Normally this medicine is used topically twice daily for 5 days. If the infection is not clear after 5 days return to your physician for repeat exam. Good luck.

Typically you should: use it for approximately 2 weeks. But if your skin infection isn't better after 2-3 days of use, you may need oral medications. See dermatologist if not improving in 2-3 days
