What is nevirapine, and how does it work (mechanism of action)?
Nevirapine is an oral medication that is used for the treatment of infections with the human immunodeficiency virus (HIV). It is in a class of drugs called reverse transcriptase inhibitors that also includes zalcitabine (Hivid), zidovudine (Retrovir), didanosine (Videx), and lamivudine (Epivir). It is in a subclass of protease inhibitors called nonnucleoside protease inhibitors that includes efavirenz (Sustiva) and delavirdine (Rescriptor). During infection with HIV, the HIV virus multiplies within the body's cells. The newly-formed viruses then are released from the cells and spread throughout the body where they infect other cells. In this manner, the infection spreads to new, uninfected cells that the body is continually producing, and HIV infection is perpetuated. When producing new viruses, the HIV virus must manufacture new DNA for each virus. Reverse transcriptase is the enzyme that the virus uses to form this new DNA. Nevirapine directly inhibits the activity of reverse transcriptase and blocks the production of DNA and new viruses. Nevirapine does not kill existing HIV virus and it is not a cure for HIV. The FDA approved nevirapine in September 1996.
What brand names are available for nevirapine?

Is nevirapine available as a generic drug?
GENERIC AVAILABLE: Yes

What are the side effects of nevirapine?
The most common side effects of nevirapine are:
The most serious side effects of nevirapine are:
- liver failure,
- severe skin reactions,
- decreased white blood cells, and
- muscle breakdown (rhabdomyolysis).
Like other antiretroviral drugs, use of nevirapine is associated with redistribution or accumulation of body fat. Immune reconstitution syndrome which is an inflammatory response to infection may occur in patients treated with combination anti-HIV therapy.
What is the dosage for nevirapine?
The starting dose for adults is 200 mg daily (lead-in period). After 14 days the dose should be increased to 200 mg every 12 hours or 400 mg of extended release once daily. The 14 day lead-in period must be observed in order to reduce the incidence of rash, and it should not be longer than 28 days. Any patient who develops a rash during the lead-in period should not receive twice daily treatment or extended release tablets until the rash has resolved. Nevirapine must be administered in combination with other anti-HIV drugs because the HIV virus quickly becomes resistant nevirapine when it is used alone. Nevirapine may be administered without regard to meals since food does not reduce its absorption.
What drugs or supplements interact with nevirapine?
Many drugs can interact with nevirapine, or make it less effective. Not all possible interactions are listed here.
Avoid drinking alcohol, which may increase your risk of liver damage.
Tell your doctor about all your current medicines and any you start or stop using, especially:
- antiviral medication to treat hepatitis C;
- antibiotics or antifungal medicine;
- birth control pills;
- blood thinners (warfarin and others);
- ergot medicine (dihydroergotamine, ergonovine, and others);
- heart or blood pressure medication;
- medicine to prevent organ transplant rejection; or
- seizure medication.
This list is not complete, and many other drugs can interact with nevirapine. Give a list of all your medicines to any health care professional who treats you. This includes prescription and over-the-counter medicines, vitamins, and herbal products.
Is nevirapine safe to take if I'm pregnant or breastfeeding?
Nevirapine is excreted in human breast milk. Nursing should be discontinued during nevirapine therapy. In addition, HIV infected mothers should not nurse because of the risk of transmitting HIV to an infant that is not infected.
What else should I know about nevirapine?
What preparations of nevirapine are available?
Tablets: 200 mg; Suspension: 10 mg/ml. Tablets (extended release): 400 mg.
How should I keep nevirapine stored?
Tablets and suspension should be stored at room temperature, 15 C to 30 C (59 F to 86 F).

AIDS (Acquired Immunodeficiency Syndrome)
AIDS is the advanced stage of HIV infection. Symptoms and signs of AIDS include pneumonia due to Pneumocystis jiroveci, tuberculosis, toxoplasmosis, seizures, weakness, meningitis, yeast infection of the esophagus, and Kaposi's sarcoma. Anti-retroviral therapy (HAART) is used in the treatment of AIDS.
Human Immunodeficiency Virus (HIV)
HIV (human immunodeficiency virus) infection left untreated causes AIDS (acquired immunodeficiency syndrome). Still incurable, AIDS describes immune system collapse that opens the way for opportunistic infections and cancers to kill the patient. Early symptoms and signs of HIV infection include flu-like symptoms and fungal infections, but some people may not show any symptoms for years. Highly active antiretroviral therapy (ART) is the standard treatment for HIV infection. These combination drug regimens have made HIV much less deadly, but a cure or vaccine for the pandemic remains out of reach. HIV is usually transmitted through sexual contact or sharing IV drug needles, but can also infect someone through contact with infected blood. Sexual abstinence, safe sex practices, quitting IV drugs (or at least using clean needles), and proper safety equipment by clinicians and first responders can drastically reduce transmission rates for HIV/AIDS.
