Famciclovir is used to treat infections caused by certain kinds of viruses. It treats shingles caused by herpes zoster. It also treats outbreaks of herpes simplex that cause cold sores around the mouth, sores around the anal area, and herpes that are genital. In people with frequent outbreaks of genital herpes, famciclovir is used to help reduce the true amount of future episodes.
Famciclovir is an antiviral drug. However, it is not a cure for these infections. The viruses that cause these infections continue to live in the physical body even between outbreaks. Famciclovir decreases the length and severity of these outbreaks. It helps the sores heal faster, keeps sores that are new forming, and decreases pain/itching. This medicine may also help reduce exactly how long pain remains after the sores heal. In addition, in people with a weakened immune system, famciclovir can reduce steadily the threat of the virus spreading to many other parts of the body and causing serious infections.
