Mupirocin is an antibacterial cream so is used to treat bacterial infection so it will not help a cold sore, which is a viral infection. However, sometimes days after the cold sore has started it may become bacterially infected when the mupirocin will help clear the bacterial infection.
I swear by this stuff! I have suffered with cold sores my whole life! I get it very bad and it can sometimes break out all over my face. My doctor gave me this about 4 years ago and I have used this ever since! Abreva has nothing on this stuff! 3 days and it's like it was never there! It will never fully allow it to break out if you get it right away!
