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.
Unless your doctor tells you otherwise, apply mupirocin 2-3 times a day for ten days. Your skin may sting a little at first but this should soon pass. Mupirocin is an antibacterial cream/ointment which is used to treat small areas of skin infection. It is sometimes used to treat infections such as impetigo in children.
