Famvir is a medication that contains the active substance famciclovir, which belongs to the family of antiviral drugs.

Famvir is mainly used for the treatment of herpes virus infections, including herpes genitalis, herpes zoster (shingles), and cold sores caused by herpes labialis.

Famvir works by stopping the spread of the herpes virus, reducing the severity and duration of symptoms, and preventing the virus from multiplying in the body.

However, it is not a cure for herpes infections and the viruses that cause these infections continue to live in the body even after treatment with Famvir.
