Zovirax is used to treat infections caused by herpes viruses. Illnesses caused by herpes viruses include herpes infections of the skin, herpes on lips, genital herpes, cold sores, shingles, and chicken pox and others. Sometimes acyclovir is given to help prevent the infection from coming back.
Zovirax is an antiviral drug. It slows the growth and spread of the herpes virus so that the body can fight off the infection. Zovirax will not cure herpes infections, but it can lessen the symptoms of the infection. It makes symptoms of the infection less painful and irritating.
