Etravirine will not cure or prevent HIV infection or AIDS; however, it helps keep the HIV virus from reproducing and appears to slow the destruction of the immune system. This may help delay some of the problems related to AIDS or HIV disease. Etravirine will not keep you from spreading HIV to other people. People who take this medicine may continue to have other problems related to AIDS or HIV disease.

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