Important Warning
Famciclovir is not a cure for herpes infections. It will not prevent the spread of the virus to others and may not prevent recurrent infections. To reduce the risk of transmission, always practice safe sex, including the use of latex or polyurethane condoms, even during symptom-free periods.

Uses for Famciclovir
Famciclovir is an antiviral medication used to treat herpes virus infections, including:

Shingles (herpes zoster)
Genital herpes (initial outbreaks and recurrent episodes)
Cold sores (herpes labialis)
Suppression of recurrent herpes in individuals with a healthy immune system
Famciclovir works by slowing the growth and spread of the herpes virus, allowing the immune system to control the infection more effectively.
