Famvir is manufactured by Novartis Pharmaceuticals Inc. This medicine is an antiviral used to treat herpes zoster (shingles) and genital herpes. It may also be used to treat other conditions as determined by your doctor.
Why is Famvir prescribed?
Famvir tablets are used to treat herpes zoster, commonly referred to as ""shingles," in adults. Shingles is a painful rash with raised, red pimples on the trunk of the body, usually the back. Because it is caused by the same virus that causes chickenpox, only people who have had chickenpox can get shingles. When prescribed for shingles, Famvir works best in people age 50 or over.
Famvir is also prescribed to treat attacks of genital herpes and to prevent future flare-ups. For people with HIV infections, it is used as a treatment for both genital and oral herpes.

Most important fact about Famvir
Famvir is most effective if started within the first 48 hours after shingles first appears; treatment should be started at the first sign or symptom of genital herpes. Famvir treatment may not be effective if it is delayed more than 72 hours after the herpes zoster rash first appears or more than 6 hours after genital herpes becomes evident. Thus, it is important to see your doctor as soon as possible after symptoms appear.
How should you take Famvir?
For maximum benefit, take Famvir for the full time of treatment, even if your symptoms begin to clear up. Do not, however, take Famvir more often or for a longer time than your doctor directs. You may take Famvir with meals or in between. --If you miss a dose...Take the forgotten dose as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never take two doses at the same time. --Storage instructions...
