Table of contents:

Epivir HBV is an antiviral medication that is used to treat chronic hepatitis B virus infection associated with evidence of hepatitis B viral replication and active liver inflammation. It contains an active ingredient called lamivudine. Lamivudine is in a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). It works by preventing the virus from multiplying in the body, which can slow down or stop the damage to the liver.

Epivir HBV can be used along with other medications to treat human immunodeficiency virus (HIV) infection in adults and children 3 months of age and older. It is not a cure for hepatitis B, but it can help slow the progression of the disease and improve liver health. Epivir HBV is not effective against other forms of viral hepatitis, such as hepatitis C.

Use and Dosage

Lamivudine is typically taken once or twice a day in tablet form, with or without food, as directed by your doctor or pharmacist. Carefully follow the instructions on your prescription label and ask your healthcare provider to clarify any questions you may have. Never take more or less of lamivudine than directed by your doctor.

While lamivudine can help manage and control HIV and hepatitis B, it is not a cure for either condition. You should continue taking lamivudine even if you feel well, and never stop taking it without first discussing it with your healthcare provider. If you miss a dose of lamivudine or need more, contact your doctor or pharmacist. Stopping or missing doses of lamivudine could make it more difficult to effectively treat your condition.

  • Exacerbations of Hepatitis B: Discontinuation of Epivir HBV can cause severe acute exacerbations of hepatitis B in patients co-infected with hepatitis B virus (HBV) and HIV-1 (Human Immunodeficiency Virus 1). Therefore, patients should be closely monitored for several months after stopping Epivir HBV.
  • Risk of Lactic Acidosis: Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogs alone or in combination with antiretrovirals.
  • Risk of HIV-1 Resistance: Epivir HBV should not be used for the treatment of HIV-1 infection because the dose of lamivudine in Epivir HBV is not sufficient to treat HIV-1 infection.
  • Use with Sorbitol: When possible, avoid concomitant use of sorbitol-containing medicines with lamivudine, which may interfere with the absorption of the medication.
  • Risk of Hepatic Decompensation: Discontinuation of Epivir HBV may lead to severe acute exacerbations of hepatitis B associated with liver decompensation and/or liver failure.
  • Use in Pregnant Women: The safety of Epivir HBV in pregnant women has not been established. Therefore, pregnant women should use Epivir HBV only if the potential benefit justifies the potential risk to the fetus.
  • Use in Breastfeeding Women: It is not known whether lamivudine is excreted in human milk. Therefore, caution should be exercised when Epivir HBV is administered to a nursing woman.
