General Information

Famvir is an oral antiviral prescription medication. The generic name of the medicine is famciclovir. Famciclovir is used to treat the symptoms of herpes zoster, a herpes virus infection of the skin. The dose of famciclovir will be different for different patients. Famciclovir will not prevent the spread of genital herpes. It is not known whether famciclovir passes into the breast milk of humans; however, it does pass into the milk of rats. Famciclovir is not recommended during breast-feeding because it may cause unwanted effects in nursing babies. This medicine is also used to treat recurrent herpes virus infections of the mucous membranes and genitals in HIV-infected patients. Famciclovir is best used within 48 hours after the symptoms of shingles (for example, pain, burning, blisters) begin to appear, or within 6 hours after the symptoms of recurrent genital herpes (for example, pain, blisters) begin to appear. Famciclovir itself does not kill the virus, but by stopping it from reproducing the virus is present in lower numbers. The lower numbers mean that the body's immune system can more easily overcome the virus.
