Famciclovir is used to deal with infections caused by certain kinds of viruses. It treats shingles caused by herpes zoster. It treats outbreaks of herpes simplex that cause cold sores across 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 quantity 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 severity and length of these outbreaks. It helps the sores heal faster, keeps sores that are new forming, and decreases pain/itching. This medication also may help reduce just how long pain remains after the sores heal. In addition, in people with a weakened system that is immune famciclovir can reduce steadily the threat of the virus spreading with other parts of the body and causing severe infections.
