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.
