Lamivudine, when used alone or in combination with other antiviral medications, can cause serious damage to the liver and a condition called lactic acidosis. If you experience any of the following symptoms, call your doctor immediately: nausea, loss of appetite, excessive tiredness, weakness, dark yellow or brown urine, unusual bleeding or bruising, flu-like symptoms, yellowing of the skin or eyes, and pain in the upper right part of your stomach. Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to lamivudine.
Epivir tablets and liquid (used to treat human immunodeficiency virus [HIV]) are not interchangeable with Epivir-HBV tablets and liquid (used to treat hepatitis B infection). Epivir contains a higher dose of lamivudine than Epivir-HBV. Treatment with Epivir-HBV in patients infected with HIV may cause the HIV virus to be less treatable with lamivudine and other medicines. If you have both HIV and hepatitis B, you should take only Epivir. If you are taking Epivir-HBV for hepatitis B infection, talk to your doctor about your risks for HIV infection.
WHY is this medicine prescribed?
Lamivudine (Epivir) is used along with other medications to treat human immunodeficiency virus (HIV) infection. Lamivudine (Epivir-HBV) is used to treat hepatitis B infection. Lamivudine is in a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). It works by decreasing the amount of HIV and hepatitis B in the blood. Although lamivudine does not cure HIV, it may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other life-style changes may decrease the risk of transmitting (spreading) the HIV virus to other people.
HOW should this medicine be used?
Lamivudine comes as a tablet and liquid to take by mouth. Lamivudine (Epivir) is usually taken every 12 hours (twice a day). Lamivudine (Epivir-HBV) is usually taken once a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take lamivudine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Continue to take lamivudine even if you feel well. Do not stop taking lamivudine without talking to your doctor.
Are there OTHER USES for this medicine?
Lamivudine is also used sometimes in combination with zidovudine (Retrovir, AZT) to treat healthcare workers or other individuals exposed to HIV infection after accidental contact with HIV-contaminated blood, tissues, or other body fluids. Talk to your doctor about the possible risks of using this drug for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
