Antiviral: Antivirals are best taken right when u feel the herpes blister (most often the cause of mouth/lip cold sore). Otherwise otc abreva is pretty good.

Bacitracin: If it is just a traumatic wound then the best treatment is keep it clean and well coated with Bacitracin ointment. If it is actually a "cold sore" then you probably need an anti-viral medication as well.
