Epivir

Generic name: Lamivudine.

Other brand names: 3-TC.

Epivir is an antiviral. It inhibits the progression of the HIV virus and significantly raises levels of AZT in blood, thus slowing the progression of AIDS. Used in combination with AZT and a protease inhibitor for people who do not respond to single-drug therapy. 

Quick Facts About Epivir

Purpose

Used to slow the progress of the human immunodeficiency virus (HIV) in adults, which can lead to acquired immunodeficiency syndrome (AIDS). Also prescribed to treat HIV-positive children over 3 months.

Take exactly as prescribed. Do not share Epivir, and do not increase prescribed dose.

  • Usual adult dose: 150 milligrams twice per day. For adults weighing under 110 pounds — 1 milligram per pound of body weight twice per day. Doctor will reduce dose as kidney function decreases.
  • Usual child dose: 12 years and older — follow adult dosing instructions. 3 months to 12 years — approximately 2 milligrams per pound of body weight twice per day up to no more than 150 milligrams per dose. Not recommended for children under 3 months.

Special Cautions

Effects of Epivir on pregnant women not known. If pregnant or planning to become pregnant, inform your doctor immediately. Potential benefits may outweigh potential risks. Do not breastfeed; HIV appears in breast milk and could affect a nursing infant.

Seniors may be prescribed a lower dose, depending on kidney function. Otherwise, no special precautions apply to seniors.

Children may experience tingling in the hands and feet. Inform your doctor immediately if your child develops symptoms of pancreatic inflammation, including feinting, fever, general feeling of extreme illness, shallow and rapid breathing, tense abdominal muscles, or very severe abdominal pain.

  • If you have kidney disease, you may need a lower dose.
  • Long-term effects of medication still are not known. Since the HIV virus remains in the body, risk is still present for complications including opportunistic infections such as pneumonia, tuberculosis, and fungal infection. It is important to remain under the care of a doctor and to go to follow-up appointments.
  • Does not reduce risk of transmitting HIV to others through sexual contact or blood contamination. Always use condoms and never share needles or equipment for injections with other people.
  • May affect the results of blood tests. Inform any doctor or dentist you visit while taking medication of Epivir therapy.
