Epivir solution

Pronunciation

Generic Name: lamivudine (la-MIV-ue-deen)
Brand Name: Epivir

Epivir solution may cause severe and sometimes fatal liver problems or high blood acid levels (lactic acidosis). Contact your doctor right away if you develop yellowing of the skin or eyes; dark urine; pale stools; stomach pain; nausea; vomiting; diarrhea; persistent loss of appetite; fast or difficult breathing; slow or irregular heartbeat; unusual weakness or tiredness; muscle pain or tenderness; unusual feeling of cold (eg, in arms or legs); or unusual drowsiness, dizziness, or lightheadedness.

Some patients with both hepatitis B virus (HBV) and HIV infection who took Epivir solution experienced severe worsening of HBV infection after they stopped it. Patients who have both HBV and HIV infection need close medical follow-up to check for worsening liver problems for at least several months after they stop Epivir solution. Keep all doctor and lab appointments. Do not stop taking Epivir solution without checking with your doctor.

Epivir solution contains a higher dose of the same ingredient found in Epivir-HBV. Do not switch between Epivir and Epivir-HBV without checking with your doctor. Epivir-HBV does not contain the correct amount of medicine to treat HIV infection.


Epivir solution is used for:

Treating HIV infection in combination with other medicines.

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

Do NOT use Epivir solution if:

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

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

Before using Epivir solution:

Some medical conditions may interact with Epivir solution. 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), lactic acidosis, kidney problems, diabetes, or a nerve disorder
  • if you are very overweight

Some MEDICINES MAY INTERACT with Epivir solution. 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 Epivir solution's side effects
  • Zalcitabine because it may decrease Epivir solution's effectiveness

This may not be a complete list of all interactions that may occur. Ask your health care provider if Epivir solution 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 Epivir solution:

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

  • Take Epivir solution by mouth with or without food.
  • Use a measuring device marked for medicine dosing. Ask your pharmacist for help if you are unsure of how to measure your dose.
  • Continue to take Epivir solution even if you feel well. Do not miss any doses.
  • Taking Epivir solution at the same time each day will help you remember to take it.
  • If you miss a dose of Epivir solution, 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 Epivir solution.

Important safety information:

  • Epivir solution may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Epivir solution with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
  • When your medicine supply is low, get more from your doctor or pharmacist as soon as you can. Do not stop taking Epivir solution, even for a short period of time. If you do, the virus may grow resistant to the medicine and become harder to treat.
  • Epivir solution is not a cure for HIV infection. Patients may still get illnesses and infections associated with HIV. Remain under the care of your doctor.
  • Epivir solution 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.
  • Epivir solution 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 Epivir solution.
  • Cases of worsening liver disease have been reported when Epivir solution 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 Epivir solution. Some patients have had worsening HBV after stopping use of Epivir solution. Tell your doctor about any new or unusual symptoms that you notice after stopping treatment.
  • Diabetes patients - Epivir solution contains sucrose and 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 Epivir solution. The cause and long-term effects of these changes are unknown. Discuss any concerns with your doctor.
  • Lab tests, including liver and kidney function tests, may be performed while you use Epivir solution. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
  • Use Epivir solution with caution in the ELDERLY; they may be more sensitive to its effects.
  • Use Epivir solution 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.
  • Epivir solution should be used with extreme caution in CHILDREN who are younger than 3 months old or who weigh less than 31 pounds; safety and effectiveness in these children have not been confirmed.
  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Epivir solution while you are pregnant. Epivir solution is found in breast milk. Do not breast-feed while taking Epivir solution. Mothers infected with HIV should not breast-feed. There is a risk of passing the HIV infection or Epivir solution to the baby.
