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.
Mupirocin dried my cold sore up in a few days , better than Abreva...
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!
