What is the dosage and how should it be used?
Lamivudine comes as a tablet and liquid to be taken orally. Lamivudine (Epivir®) is usually taken every 12 hours (twice a day). Lamivudine (Epivir-HBV®) is usually taken once a day.
Take this medication exactly as your doctor has prescribed it for you. Do not use more of the medication than recommended. Do not take lamivudine for longer than your doctor has prescribed.
Lamivudine can be taken with or without food.
To ensure that you get a correct dose, measure the liquid forms of lamivudine with a special dose-measuring spoon or cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
Epivir tablets and liquid contain a higher dose of lamivudine than Epivir-HBV®. Epivir® is for treating HIV and Epivir-HBV® is for treating hepatitis B. Each time you get a refill of this medication, be sure you have received the correct brand to treat your condition.
Furthermore, treatment of HIV/AIDS almost always requires using many medicines together. To best treat your condition, use all of your medications as directed by your doctor. Do not change your doses or medication schedule without advice from your doctor. Every person with HIV or AIDS should remain under the care of a doctor.
Additionally, in order to be sure this medication is helping your condition, your blood will need to be tested on a regular basis. Your kidney or liver function may also need to be tested. It is important that you not miss any scheduled visits to your doctor.
