Severe, life-threatening, in some cases fatal, hepatotoxicity and skin reactions (eg, Stevens-Johnson syndrome; toxic epidermal necrolysis; and hypersensitivity reactions characterized by rash, constitutional findings, and organ dysfunction) have been reported. Women, including pregnant women, and/or patients with higher CD4+ cell counts are at higher risk of hepatotoxicity. Permanently discontinue nevirapine following severe hepatic, skin, or hypersensitivity reactions. Monitor patients intensively during the first 18 weeks of therapy with nevirapine to detect potentially life-threatening hepatotoxicity or skin reactions. Strictly follow the 14-day lead-in period with immediate-release nevirapine 200 mg daily dosing .
Non-Nucleoside Reverse Transcriptase Inhibitor
Nevirapine is used in combination with other medicines for the treatment of the infection caused by the 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.
