What is lamivudine (Epivir)?
Lamivudine is an antiviral medication that prevents human immunodeficiency virus (HIV) or hepatitis B virus cells from multiplying in your body.
Epivir is for treating HIV, which causes the acquired immunodeficiency syndrome (AIDS). Epivir is not a cure for HIV or AIDS.
Epivir-HBV is for treating hepatitis B. Epivir-HBV should not be used in people who are infected with both hepatitis B and HIV.
Lamivudine may also be used for purposes not listed in this medication guide.

What is the most important information I should know about lamivudine (Epivir)?
You should not take lamivudine if you are allergic to it.
The Epivir brand of lamivudine (for treating HIV) should not be taken together with any HIV combination medicine that contains lamivudine or emtricitabine. This includes Atripla, Combivir, Complera, Emtriva, Epzicom, Trizivir, and Truvada.
The Epivir-HBV brand of lamivudine (for treating hepatitis B) should not be taken together with any other medication that contains lamivudine, which includes Combivir, Epivir, Epzicom, and Trizivir.
Before taking lamivudine, tell your doctor if you have kidney disease, liver disease, a history of pancreatitis, or if you have used a medicine similar to lamivudine in the past, such as abacavir (Ziagen), didanosine (Videx), emtricitabine (Atripla, Complera, Emtriva, Truvada), stavudine (Zerit), tenofovir (Viread), zalcitabine (Hivid), or zidovudine (Retrovir).
Some people develop lactic acidosis while taking lamivudine. Early symptoms may get worse over time and this condition can be fatal. Get emergency medical help if you have even mild symptoms such as: muscle pain or weakness, numb or cold feeling in your arms and legs, trouble breathing, stomach pain, nausea with vomiting, fast or uneven heart rate, dizziness, or feeling very weak or tired.
If you have hepatitis B you may develop liver symptoms after you stop taking this medication, even months after stopping. Your doctor may want to check your liver function for several months after you stop using lamivudine. Visit your doctor regularly.
Lamivudine can also cause severe or life-threatening effects on your liver or pancreas. Call your doctor at once if you have any of these symptoms while taking lamivudine: severe pain in your upper stomach spreading to your back, nausea and vomiting, fast heart rate, itching, loss of appetite, dark urine, clay-colored stools, or jaundice (yellowing of the skin or eyes).
Epivir tablets and liquid contain a higher dose of lamivudine than Epivir-HBV. Each time you get a refill of this medication, be sure you have received the correct brand to treat your condition.
