Epivir-Hbv is an antiretroviral (ARV) used in the treatment of chronic hepatitis B virus infection associated with evidence of hepatitis B viral replication and active liver inflammation.

Epivir-Hbv is a nucleoside reverse transcriptase inhibitor (NRTI). It blocks an enzyme (protein) found in HIV and HBV called reverse transcriptase that usually helps the virus make copies of itself. By blocking reverse transcriptase, lamivudine (Epivir) prevents HIV and HBV from making copies of itself and spreading.

Epivir-Hbv is typically dosed as follows:

• Adults: The typical dose is 100 mg by mouth once daily.
• Children ages 2-17 years: Your child’s provider will determine the dose based on your child’s body weight. The typical dose is 3 mg/kg of body weight by mouth daily, up to a maximum of 100 mg.
