Prescription Drug Information

Information on Famvir^Ž

Generic name: Famciclovir

USES: 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.

HOW TO TAKE THIS MEDICATION: 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.

CHILDREN

Safety and effectiveness in children under the age of 18 have not been established.

SIDE EFFECTS: Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Famvir.

More common side effects may include:

Constipation, diarrhea, dizziness, fatigue, fever, headache, nausea, vomiting

Less common side effects may include:

Abdominal pain, back pain, chills and fever, gas, indigestion, injury, insomnia, irritated sinuses, itching, joint pain, loss of appetite, pain, prickling or burning sensation of the skin, sleepiness, sore throat, upper respiratory infection

There have been infrequent cases of hallucinations, hives, and rash, and some people---especially older adults---may experience confusion, including delirium and disorientation.

PRECAUTIONS: Famvir speeds healing of shingles and genital herpes, but it is not a cure. It may not prevent transmission of genital herpes to others, so you should avoid sexual intercourse whenever you have symptoms of the disease.

If you have any kidney problems, be sure your doctor knows about them before prescribing Famvir for you.

DRUG INTERACTIONS: If Famvir is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Famvir with probenecid (Benemid), a drug used to treat gout (a type of arthritis).

NOTES: The effects of Famvir during pregnancy have not been adequately studied. If you are pregnant or plan to become pregnant, inform your doctor immediately. Famvir should be used during pregnancy only when the benefit to the mother clearly outweighs the potential risk to the baby. Famvir may appear in breast milk, and could affect a nursing infant. If this drug is essential to your health, your doctor may advise you to discontinue breastfeeding until your treatment with Famvir is finished.

MISSED 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: : Store at room temperature and keep away from moisture and sunlight. Keep this and all medications out of the reach of children.
