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.
Before using mupirocin, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients (such as polyethylene glycol found in some brands), which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
