Dosing
For adults with HIV (or children over 12), the dose is 300mg once daily, or 150mg twice a day. Lamivudine is never used on its own in the treatment of HIV.
For the treatment of adults with hepatitis B, the dose is 100mg once daily. If co-infected with HIV, then the dose is as for HIV.
For a child 3 months to 12 years old, about 1.4-2 mg per lb. of body weight twice a day, no more than 150 mg per dose.
