Uses For rilpivirine
Rilpivirine is used together with other medicines to treat human immunodeficiency virus (HIV) infections. HIV is the virus that causes acquired immune deficiency syndrome (AIDS). rilpivirine is usually given to patients who have not received any HIV treatment in the past. Rilpivirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI). It works by lowering the amount of HIV in the blood.
Rilpivirine will not cure HIV infection or AIDS; however, 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. Rilpivirine will not keep you from spreading HIV to other people. People who receive rilpivirine may continue to have some of the problems usually related to AIDS or HIV disease.
rilpivirine is available only with your doctor's prescription.
