  • Product overview

Treating HIV infection in combination with other medicines.

Lamivudine is a nucleoside analogue. It works by blocking the growth of HIV.

Do NOT use lamivudine if:

  • you are allergic to any ingredient in lamivudine
  • you have an enlarged liver, abnormal liver function tests, or high levels of lactic acid in the blood (lactic acidosis)
  • you are taking emtricitabine, zalcitabine, or another medicine containing lamivudine

Contact your doctor or health care provider right away if any of these apply to you.

Before using lamivudine:

Some medical conditions may interact with lamivudine. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

  • if you are pregnant, planning to become pregnant, or are breast-feeding
  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
  • if you have allergies to medicines, foods, or other substances
  • if you have a history of muscle problems, pancreas problems, abnormal blood cell counts, liver disease (eg, hepatitis) or other liver problems (eg, abnormal liver function tests), kidney problems, diabetes, lactic acidosis, or a nerve disorder
  • if you are very overweight
  • if the patient is a child who has a history of pancreas problems or who has previously taken other medicine for HIV infection

Some MEDICINES MAY INTERACT with lamivudine. Tell your health care provider if you are taking any other medicines, especially any of the following:

  • Interferon alfa or ribavirin because severe liver problems may occur
  • Emtricitabine, other medicines that contain lamivudine, or trimethoprim because they may increase the risk of lamivudine's side effects
  • Zalcitabine because it may decrease lamivudine's effectiveness

This may not be a complete list of all interactions that may occur. Ask your health care provider if lamivudine may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.


How to use lamivudine:

Use lamivudine as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • An extra patient leaflet is available with lamivudine. Talk to your pharmacist if you have questions about this information.
  • Take lamivudine by mouth with or without food.
  • Continue to take lamivudine even if you feel well. Do not miss any doses.
  • Taking lamivudine at the same time each day will help you remember to take it.
  • If you miss a dose of lamivudine, take it as soon as possible. If it is within 2 hours of your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use lamivudine.

Important safety information:

  • Tell your doctor or dentist that you take lamivudine before you receive any medical or dental care, emergency care, or surgery.
  • When your medicine supply is low, get more from your doctor or pharmacist as soon as you can. Do not stop taking lamivudine, even for a short period of time. If you do, the virus may grow resistant to the medicine and become harder to treat.
  • Lamivudine is not a cure for HIV infection. Patients may still get illnesses and infections associated with HIV. Remain under the care of your doctor.
  • Lamivudine does not stop the spread of HIV to others through blood or sexual contact. Use barrier methods of birth control (eg, condoms) if you have HIV infection. Do not share needles, injection supplies, or items like toothbrushes or razors.
  • Lamivudine may improve immune system function. This may reveal hidden infections in some patients. Tell your doctor right away if you notice symptoms of infection (eg, fever, sore throat, weakness, cough, shortness of breath) after you start lamivudine.
  • Cases of worsening liver disease have been reported when lamivudine is stopped in patients with both HIV and HBV infection. Discuss any medicine changes with your doctor.
  • If you have HBV infection, your doctor will perform lab tests for several months after you stop taking lamivudine. Some patients have had worsening HBV after stopping use of lamivudine. Tell your doctor about any new or unusual symptoms that you notice after stopping treatment.
  • Diabetes patients - Lamivudine may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
  • Changes in body fat (eg, an increased amount of fat in the upper back, neck, breast, and trunk, and loss of fat from the legs, arms, and face) may occur in some patients taking lamivudine. The cause and long-term effects of these changes are unknown. Discuss any concerns with your doctor.
  • Lab tests may be performed while you use lamivudine. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
  • Use lamivudine with caution in CHILDREN; they may be more likely to experience certain side effects, including pancreas problems, wheezing, ear pain or swelling, or swollen lymph nodes.
  • If your child is taking lamivudine, the dose may need to be changed as your child's weight changes. Have your child's weight checked often. Talk with the doctor before changing your child's dose.
  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using lamivudine while you are pregnant. Lamivudine is found in breast milk. Do not breast-feed while taking lamivudine. Mothers infected with HIV should not breast-feed. There is a risk of passing the HIV infection or lamivudine to the baby.
