AIDS Home > Lamivudine Dosing
The recommended lamivudine dosage for adults with hepatitis B is 100 mg once daily. For the treatment of HIV or AIDS, the usual starting dosage is 150 mg twice daily or 200 mg once daily. Lamivudine dosing for children is determined by weight, about 1.36 mg per pound once a day (for hepatitis B) or 1.8 mg per pound twice daily (for HIV or AIDS).
The dose of lamivudine (Epivir®) that your healthcare provider recommends will vary depending on a number of factors, including:
- Whether you have HIV or hepatitis B
- Your age
- Whether you develop bothersome or dangerous side effects of lamivudine
- Other medical conditions you may have
- Other medications you may currently be taking.
As always, do not adjust your lamivudine dose unless your healthcare provider specifically instructs you to do so.
The recommended lamivudine dose for treating hepatitis B in adults is lamivudine (Epivir-HBV) 100 mg once daily. For children 2 to 17 years old, lamivudine dosing is based on weight, about 1.36 mg per pound once daily (up to a maximum of 100 mg per day).
A lower lamivudine dosage may be recommended for people with kidney disease (such as kidney failure).
The recommended lamivudine dose for treating HIV or AIDS in adults is 150 mg twice daily or 300 mg once daily. For children age 3 months to 16 years old, the recommended dose is based on weight, about 1.8 mg per pound twice daily (up to a maximum of 150 mg twice daily). A lower lamivudine dosage may be recommended for people with kidney problems.
For people with both hepatitis B and HIV or AIDS, the dose for HIV or AIDS (which is higher) should be used.
