Conventional antivirals are only beneficial early on in the cold sore progression – during the “tingle” phase… Propovir is effective during any of the cold sore stages, from tingle or blister through to healing.
Propovir effectively targets all stages of the cold sore, from the initial tingle or blister right through to the healing stage. The time for the development of a cold sore is variable. The whole episode, from tingle stage to complete healing, usually lasts from 7 to 10 days.
Cold sores are infectious from the time of the first tingle until the scab has dried. The virus is present in the blisters and in the fluid, and can spread.
