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.
Antiviral creams can reduce the time it takes a cold sore to heal if applied at the very first sign of a cold sore. Docosanol cream (Abreva) is available over the counter. Acyclovir (Zovirax) cream and penciclovir (Denavir) cream are available by prescription.
