Why is FAMCICLOVIR prescribed?

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, FAMCICLOVIR works best in people age 50 or over.

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 FAMCICLOVIR without prescriptions

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. 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.
How should you take FAMCICLOVIR?

For maximum benefit, take FAMCICLOVIR for the full time of treatment, even if your symptoms begin to clear up. Do not, however, take FAMCICLOVIR more often or for a longer time than your doctor directs.

You may take FAMCICLOVIR 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.
