What is etravirine (and what is it used to treat)?
Etravirine (brand name Intelence) is an antiretroviral medicine used to treat HIV-1 infection. It’s prescribed as part of combination therapy for people who have already taken other HIV medicines and may have drug-resistant virus.
How does etravirine work?
Etravirine belongs to the non-nucleoside reverse transcriptase inhibitor (NNRTI) class. NNRTIs block the HIV reverse transcriptase enzyme, which HIV needs to copy its genetic material. Etravirine is designed to retain activity against some HIV strains that are resistant to earlier NNRTIs.
What are the common side effects patients ask about?
Commonly reported side effects for etravirine include rash and gastrointestinal effects such as nausea and diarrhea. Skin reactions are a key concern with NNRTIs, so clinicians typically advise patients to report new or worsening rash promptly.
Is etravirine ever used with other HIV drugs?
Yes. Like most HIV therapies, etravirine is intended to be taken with other antiretroviral drugs to improve viral suppression and reduce resistance risk. The exact regimen depends on prior treatment history and resistance testing.
How is etravirine taken (and does food matter)?
Etravirine dosing depends on the patient’s regimen and form prescribed. In practice, the medication is taken with food to improve absorption, and dosing schedules are set by the prescribing clinician.
Where does etravirine fit versus newer HIV options?
Etravirine is generally considered in treatment-experienced patients, including those with NNRTI resistance patterns where other options may be less effective. Newer regimens can sometimes replace older NNRTI-based strategies, but clinicians select therapy based on resistance history, drug interactions, and treatment goals.
When do patent and exclusivity issues matter for etravirine?

What drug interactions should people be careful about?
As an NNRTI, etravirine can interact with other medicines that affect liver enzymes involved in drug metabolism (for example, some antiseizure medications, rifamycin antibiotics, and certain HIV drugs). Patients should share their full medication list with their clinician or pharmacist before starting or changing therapy.
Safety red flags and urgent situations
The most urgent issue patients tend to worry about is serious rash. If a rash is severe, widespread, blistering, or accompanied by fever or other symptoms, it needs immediate medical attention.
