Lamivudine (la mi' vyoo deen) Epivir® Epivir-HBV® Epzicom® (as a combination product containing Abacavir, Lamivudine) 3TC Medications that are similar to lamivudine have caused serious damage to the liver and a life-threatening condition called lactic acidosis (buildup of lactic acid in the blood) when they were used alone or in combination with other medications that treat human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS). The risk that you will develop lactic acidosis may be higher if you are a woman, if you are overweight, or if you have been treated with medications for HIV for a long time. Tell your doctor if you have or have ever had liver disease. If you experience any of the following symptoms, call your doctor immediately: nausea; vomiting; loss of appetite; excessive tiredness; weakness; dizziness; lightheadedness; fast or irregular heartbeat; trouble breathing; dark yellow or brown urine; unusual bleeding or bruising; flu-like symptoms; light-colored bowel movements; yellowing of the skin or eyes; pain in the upper right part of your stomach; feeling cold, especially in the arms or legs; or muscle pain that is different than any muscle pain you usually experience. Tell your doctor if you have or think you may have hepatitis B virus infection (HBV; an ongoing liver infection). Your doctor may test you to see if you have HBV before you begin your treatment with lamivudine. If you have HBV and you take lamivudine, your condition may suddenly worsen when you stop taking lamivudine. Your doctor will examine you and order lab tests regularly for several months after you stop taking lamivudine to see if your HBV has worsened. 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. Keep all appointments with your doctor and the laboratory. Your doctor will order certain tests to check your body's response to lamivudine. Talk to your doctor about the risks of taking lamivudine.

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 or hepatitis B virus to other people.
