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.
