Also known as: Lamivudine
Lamivudine is used in combination with other medicines for the treatment of the infection caused by the human immunodeficiency virus (HIV). HIV is the virus that causes acquired immune deficiency syndrome (AIDS).
Lamivudine will not cure or prevent HIV infection or AIDS. It helps keep HIV from reproducing and appears to slow down the destruction of the immune system. This may help delay the development of serious health problems usually related to AIDS or HIV disease from occurring. Lamivudine will not keep you from spreading HIV to other people. People who receive this medicine may continue to have other problems usually related to AIDS or HIV disease.
Lamivudine is also used to treat chronic (long-term) hepatitis B virus (HBV) infection.
This medicine is available only with your doctor's prescription.
