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.
Diclofenac is an anti-inflammatory, sort of a souped-up Ibuprofen. So if you're looking for control of the pain of the cold-sore, it may help. But it's not going to help you with shortening the duration of the cold sore or the area that it spreads to.or that you need a prescription anti-viral, Zovirax (acyclovir), because cold sores are caused by the Herpes virus (HSV-1). Alternatively, you could get Abreva which is a non-prescription ointment that will also shorten the cold sore's lifespan.
