Product Description

Why is this medication prescribed?

Nevirapine is used along with other medications to treat human immunodeficiency virus (HIV) infection. Nevirapine is in a class of medications called non-nucleoside reverse transcriptase inhibitors (NNRTIs). It works by decreasing the amount of HIV in the blood. Although nevirapine does not cure HIV, it may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other life-style changes may decrease the risk of transmitting (spreading) the HIV virus to other people.

How should this medicine be used?

Nevirapine comes as a tablet and a suspension (liquid) to take by mouth. It is usually taken with or without food once a day for 2 weeks and twice a day after the first 2 weeks. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take nevirapine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow nevirapine with liquids such as water, milk, or soda.

Shake the liquid gently before each use to mix the medication evenly. Use an oral dosing cup or dosing syringe to measure your dose. It is best to use a syringe, especially if your dose is less than 5 mL (1 teaspoon). If you use a dosing cup, first drink all of the medication that you measured in the dosing cup. Then fill the dosing cup with water and drink the water to be sure that you get your full dose.

Nevirapine may control HIV but will not cure it. Continue to take nevirapine even if you feel well. Do not stop taking nevirapine or any of the other medications that you are taking to treat HIV or AIDS without talking to your doctor.Your doctor will probably tell you to stop taking your medications in a certain order. If you miss doses or stop taking nevirapine, your condition may become more difficult to treat.

If you do not take nevirapine for 7 days or longer, do not start taking it again without talking to your doctor. Your doctor will start you on a low dose of nevirapine, and increase your dose after 2 weeks.

Other uses for this medicine

Nevirapine is also sometimes used to prevent unborn babies whose mothers have HIV or AIDS from becoming infected with HIV during birth.
