Etravirine Overview
-
Etravirine is used along with other medications to treat human immunodeficiency virus (HIV) infection in adults and children 2 years of age and older who no longer benefit from taking other HIV medications. Etravirine is in a class of medications called non-nucleoside reverse transcriptase inhibitors (NNRTIs). It works by decreasing the amount of HIV in the blood. Although etravirine does not cure HIV, it may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other lifestyle changes may decrease the risk of transmitting (spreading) the HIV virus to other people.
