Responses (2) Mupirocin is an antibacterial so it won't work on cold sores, which is a viral infection. For what its worth i had a cold sore the size of a dime last week and after 4 days of mupirocin it almost completely vanished. I have never got rid of a cold sore so quickly.
Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered. This medicine is not for long-term use. This medicine is for use only in the nose. Do not get any of it in your eyes or on your skin. If it does get on these areas, rinse well with water right away. To help clear up your skin infection completely, keep using mupirocin for the full time of treatment, even if your symptoms have disappeared.
