Temixys

Generic name: Lamivudine And Tenofovir
Drug class: Antiviral combinations

Usage of Temixys

Lamivudine and Tenofovir combination is used together with other antiviral medicines to treat human immunodeficiency virus (HIV) infection. HIV is the virus that causes acquired immune deficiency syndrome (AIDS).

This medicine does not cure or prevent HIV 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 problems that usually result from AIDS or HIV disease. It will not keep you from spreading HIV to other people. People who receive this medicine may continue to have some of the problems usually related to AIDS or HIV disease.

This medicine is available only with your doctor's prescription.

Pediatric
