How long does it take for zovirax (acyclovir) to work? help please
A doctor has provided 1 answer
Slowly: Zovirax (acyclovir) will only speed up the healing of a cold sore by a day or two compared to how long it would have taken to heal without zovirax (acyclovir). Healing will take 4-5 days instead of 5-6 days.
