Famciclovir is an antiviral drug. It slows the growth and spread of the herpes virus so that the
body can fight off the infection. Famciclovir will not cure herpes, but it can lessen the symptoms of the
infections.
Famciclovir is used to treat infections caused by herpes viruses, including genital herpes, cold
sores, shingles, and chicken pox.
There is no cure for herpes and famciclovir will not prevent you from developing symptoms in
the future.
Famciclovir may also be used for other purposes not listed in this medication guide.
