Why is FAMTREX (Famvir, Famciclovir) prescribed?
FAMTREX (Famvir, Famciclovir) 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,
FAMTREX (Famvir, Famciclovir) works best in people age 50 or over.
FAMTREX (Famvir, Famciclovir) 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 FAMTREX (Famvir, Famciclovir) without prescriptions
FAMTREX (Famvir, Famciclovir) 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. FAMTREX (Famvir, Famciclovir) 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.

often or for a longer time than your doctor directs.
