What is acyclovir? Acyclovir is an antiviral drug. It slows the
growth and spread of the herpes virus so that the body can fight off the
infection. Acyclovir will not cure herpes, but it can lessen the symptoms of the
infection. Acyclovir is used to treat infections caused by herpes viruses.
Illnesses caused by herpes viruses include genital herpes, cold sores, shingles,
and chicken pox. Acyclovir may also be used for purposes other than those listed
in this medication guide.
