Zovirax is used in the treatment of certain infections with herpes viruses. These include genital herpes, shingles, and chickenpox.
The active ingredient in Zovirax is Aciclovir (or acyclovir). Aciclovir (acyclovir) is an antiviral agent that is highly active against Herpes Simplex (HSV) type 1 and 2 viruses.
Cold sores are usually proceeded by a feeling of tingling, burning, itching, or numbness in the spot where the Cold sore is developing. Zovirax, when applied at this stage, will inhibit the development of the cold sore to the skin.
