Description
Nevirapine is used in combination with other medicines to treat human immunodeficiency virus (HIV). HIV is the virus that causes acquired immune deficiency syndrome (AIDS).
Nevirapine is a non-nucleoside reverse transcriptase inhibitor (NNRTI). It works by lowering the amount of HIV in the blood.
Nevirapine 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. Nevirapine 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.
This product is available in the following dosage forms:
- Tablet, Extended Release
