Zovirax

The active ingredient in Zovirax is acyclovir. It belongs to a group of medications called antiviral drugs. It works to slow the growth and spread of herpes viruses in the body and improves symptoms by interfering with DNA polymerase to inhibit DNA replication. It is important to note that Zovirax is not a cure and that the herpes viruses remain in the body even if symptoms are not present.
