What is the most important information I should know about etravirine?

In rare cases, etravirine can cause a condition that results in the breakdown of skeletal muscle tissue, leading to kidney failure. Call your doctor right away if you have unexplained muscle pain, tenderness, or weakness especially if you also have fever, unusual tiredness, and dark colored urine.

Etravirine must be taken in combination with other HIV medications. However, some drugs can raise or lower your blood levels of etravirine. Etravirine can also affect blood levels of certain other drugs. This can make your medicines less effective or increase side effects. TELL YOUR DOCTOR ABOUT ALL OTHER MEDICINES YOU USE.

What is etravirine?

Etravirine is an antiviral medicine that prevents human immunodeficiency virus (HIV) from multiplying in your body.

Etravirine is used with other medicines to treat HIV in adults and children who are at least 6 years old. HIV causes the acquired immunodeficiency syndrome (AIDS). Etravirine is not a cure for HIV or AIDS.

Etravirine may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking etravirine?

You should not take etravirine if you are allergic to it.

To make sure you can safely take etravirine, tell your doctor if you have any liver disease, including hepatitis B or C.

Etravirine must be taken in combination with other HIV medications. However, there are certain combinations of medicines that should not be used together with etravirine. Follow your doctor's dosing instructions very carefully.

You SHOULD NOT take etravirine together with:

  • delavirdine;
  • efavirenz;
  • nevirapine;
  • rifabutin, rifapentine, rifampin;
  • rilpivirine;
  • St. John's wort;
  • ritonavir when given with fosamprenavir or tipranavir;
  • ritonavir in doses of more than 600 milligrams twice daily; or
  • seizure medications--carbamazepine, phenytoin, phenobarbital.

You MUST take etravirine together with ritonavir if you are also taking a protease inhibitor, such as atazanavir, dolutegravir, fosamprenavir, indinavir, or nelfinavir.

Tell your doctor if you are pregnant or plan to become pregnant during treatment. HIV can be passed to your baby if you are not properly treated during pregnancy. Take all of your HIV medicines as directed to control your infection.

Women with HIV or AIDS should not breast-feed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.

How should I take etravirine?

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended. Etravirine must be taken in combination with other HIV medications. Follow your doctor's dosing instructions very carefully.

If a child is taking this medication, tell your doctor if the child has any changes in weight. Etravirine doses are based on weight in children.

Etravirine works best if you take it after a meal. Do not take it on an empty stomach.

Do not crush, chew, or break an etravirine tablet. Swallow it whole with liquid such as water.

If you cannot swallow an etravirine tablet whole, place it into a glass of water and allow the tablet to disperse in the liquid. The tablet will not dissolve completely. Drink this mixture right away. To make sure you get the entire dose, add a little more liquid to the same glass, swirl gently and drink right away.

While using etravirine, you may need frequent blood tests at your doctor's office.

Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor's advice. Every person with HIV or AIDS should remain under the care of a doctor.

Store at room temperature away from moisture and heat. Keep the tablets in their original container.

What happens if I miss a dose?

If you are less than 6 hours late in taking your medicine, take the missed dose after your next meal. Then return to your regular dosing schedule. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid while taking etravirine?

Taking this medication will not prevent you from passing HIV to other people. Do not have unprotected sex or share razors or toothbrushes. Talk with your doctor about safe ways to prevent HIV transmission during sex. Sharing drug or medicine needles is never safe, even for a healthy person.

What are the possible side effects of etravirine?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

In rare cases, etravirine can cause a condition that results in the breakdown of skeletal muscle tissue, leading to kidney failure. Call your doctor right away if you have unexplained muscle pain, tenderness, or weakness especially if you also have fever, unusual tiredness, and dark colored urine.
