What are nevirapine tablets?
NEVIRAPINE (Viramune®) is an antiviral drug called a nonnucleoside reverse transcriptase inhibitor or NNRTI. Nevirapine is used to treat human immunodeficiency virus (HIV) infection. Nevirapine may reduce the amount of HIV in the blood and increase the number of CD4 cells (T-cells) in the blood. Nevirapine is used in combination with other drugs to treat the HIV virus. Nevirapine will not cure or prevent HIV infection or AIDS. You may still develop other infections or conditions associated with HIV. Generic nevirapine tablets are not yet available.

What should I watch for while taking nevirapine?
Severe liver reactions or skin rashes may be seen with nevirapine therapy. The risk of these reactions is greatest during the first 18 weeks of treatment, but can also occur later. If you develop a rash at any time while you are taking nevirapine, call your health care provider immediately. You must visit your prescriber or health care professional for regular checks on your progress and to watch for possible reactions. You will need to have your blood drawn regularly to monitor your therapy and your liver function. Discuss any new symptoms with your prescriber or health care professional.
Nevirapine will not cure HIV infection and you can still get other illnesses or complications associated with your health condition. Taking nevirapine does not reduce the risk of passing HIV infection to others through sexual or blood contact. It is best to avoid sexual contact so that you do not spread the disease to others. For any sexual contact, use a condom. Be careful about cuts, abrasions, and other possible sources of blood contact. Never share a needle or syringe with anyone.
If you are a women of childbearing age and are using hormone contraceptives, then you should use another form of birth control while taking nevirapine. Nevirapine may decrease the effectiveness of hormone birth control agents, including oral contraceptives.
