How is lamivudine dosed?

Several different factors determine the appropriate dose of lamivudine. The most important one is whether the drug is being used to treat hepatitis B infection or human immunodeficiency virus (HIV) infection. In the case of hepatitis B, the drug is usually taken 100 mg. once a day in HIV-negative patients and 300 mg. twice a day in HIV-positive patients. For HIV, the dose is 300 mg. once daily, sometimes split up into two 150 mg. doses each day.
