An Overview of Viramune (Nevirapine)

May 6, 2015

 < Prev  |  1  |  2 

What Should I Do if I Forget a Dose?

If you miss a dose of nevirapine, take the missed dose as soon as you remember it. But if it is almost time for your next dose, skip the missed dose and just take your next dose at the regular time. Do not take two doses at the same time to make up for a missed dose. If you stop taking nevirapine for more than 7 days, ask your health care provider how much to take before you start taking it again.

What Side Effects Can Nevirapine Cause?

Nevirapine can cause serious, life-threatening side effects. These include severe liver problems, skin rash, and skin reactions. The liver and skin problems can happen at any time during treatment, but the time of greatest risk is during the first 18 weeks of treatment. (See the WARNING above.)

Other possible side effects of nevirapine include:

  • Immune reconstitution inflammatory syndrome (IRIS), a condition that sometimes occurs when the immune system begins to recover after treatment with an HIV medicine. As the immune system gets stronger, it may have an increased response to a previously hidden infection. Tell your health care provider if you start having new symptoms after starting your HIV medicine.
  • Redistribution, loss, or gain of body fat (lipodystrophy).

Tell your health care provider if you have any side effect that bothers you or that does not go away.

These are not all the possible side effects of nevirapine. To learn more about possible side effects of nevirapine, read the drug label or package insert or talk to your health care provider or pharmacist.

The AIDSinfo fact sheet on HIV Medicines and Side Effects also includes information that may apply to nevirapine.

You can also report side effects to FDA at 1-800-FDA-1088 (1-800-332-1088) or online at

How Should Nevirapine Be Stored?

  • Store nevirapine between 59°F and 86°F (15°C to 30°C).
  • Do not use nevirapine if the original seal over the bottle opening is broken or missing.
  • Throw away nevirapine that is no longer needed or expired (out of date). Follow FDA guidelines on how to safely dispose of unused medicine.
  • Keep nevirapine and all medicines out of reach of children.
