Famciclovir (brand name: Famvir) is an antiviral medication used to treat herpes zoster (shingles) and herpes simplex virus (HSV) infections. It is a nucleoside analogue that works by interfering with the DNA synthesis of the virus.
Famciclovir is an effective and well-tolerated medication. It is generally safe for use in adults and children over the age of 12. The most common side effects are headache, nausea, and vomiting. Famciclovir is not a cure for herpes, but it can help to reduce the symptoms and prevent outbreaks.
