Zovirax cream (Acyclovir cream) is an antiviral medication that is used to treat cold sores, which are caused by herpes simplex viruses. The prescription medication helps the body fight the infection by preventing the virus from multiplying. Although Zovirax cream cannot prevent an outbreak, it can help cold sores to heal quicker when applied at the first signs of an outbreak.

Generic Zovirax Cream may also be marketed as: Acylovir
