What is Intelence?

Intelence (etravirine) is an antiviral medication that prevents human immunodeficiency virus (HIV) cells from multiplying in your body.

Intelence is used with other medications 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.

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

Important information

In rare cases, Intelence 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.
