Nevirapine ER is the generic extended-release formulation of the medication. It is manufactured by several companies, including Mylan, Aurobindo, Sciegen, and Apotex. The original brand-name product is called Viramune XR. Information and potential savings offers for both the generic and brand-name versions can be found through various pharmacy information and savings websites.

Nevirapine ER is an extended-release antiviral medication used as part of a combination regimen to control HIV-1, the virus that causes AIDS. HIV weakens the immune system by destroying cells that fight disease, leaving the body vulnerable to serious infections and cancers. Nevirapine ER works by inhibiting an enzyme HIV needs to replicate, thereby reducing the amount of virus in the body and allowing the immune system to recover. The standard adult maintenance dose is a 400 mg tablet taken once daily, with or without food. This can be taken as one 400 mg tablet or as four 100 mg tablets. A critical safety step requires a 14-day lead-in period with immediate-release nevirapine (200 mg once daily) before starting the extended-release formulation.

Common side effects of Nevirapine ER include rash, diarrhea, headache, and abdominal pain. The medication carries a boxed warning for the risk of severe, life-threatening liver toxicity (hepatotoxicity), which occurs in roughly 5% of patients. Serious skin reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, are also possible, with severe rashes occurring in about 1% of patients. Any signs of an allergic reaction (e.g., rash, swelling, difficulty breathing) or symptoms of liver problems (e.g., fatigue, nausea, jaundice) require immediate medical attention and discontinuation of the drug. This is not an exhaustive list; your prescribing doctor is the best source for discussing all potential risks and side effects relevant to your health.
