Famciclovir is used to deal with 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 round the mouth, sores around the rectum, and genital herpes. In people with frequent outbreaks of genital herpes, famciclovir is used to help reduce the true number of future episodes.
Famciclovir is an drug that is antiviral. 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 new sores from forming, and decreases pain/itching. This medication also may help reduce exactly how pain that is long after the sores heal. In addition, in people with a weakened system that is immune famciclovir can decrease the risk of the virus spreading to other parts of the body and causing severe infections.
