Severe, potentially life-threatening, and fatal skin reactions have occurred. Hypersensitivity reactions (characterized by rash, constitutional findings, and sometimes organ dysfunction, including liver failure) have also been reported. Rash most commonly occurred within 6 weeks of treatment initiation. If signs or symptoms of skin reactions or hypersensitivity reactions develop, etravirine therapy should be discontinued at once, clinical status (including liver transaminases) should be monitored, and appropriate treatment should be started. Delay in discontinuing etravirine following the onset of severe rash may result in a life-threatening reaction.
Etravirine may potentially interact with many drugs resulting in altered plasma levels of the other drugs or of etravirine. Patients should be advised to report all concurrent medications they are taking, including nonprescription medications and nutritional/herbal supplements; especially St. John's wort.
Immune reconstitution syndrome has occurred during combination antiretroviral therapy. Patients responding to therapy may develop an inflammatory response to indolent or residual opportunistic infections and require evaluation and treatment.
The potential for HIV cross-resistance among nonnucleoside reverse transcriptase inhibitors (NNRTI) exists but has not been fully explored. Cross-resistance to other NNRTIs is expected following virologic failure with an etravirine-containing regimen for the virologic failure isolates. Selection of antiretroviral agents for a patient's medication regimen should be done carefully.
Use in combination with other active antiretroviral agents will increase the likelihood of treatment response. Patients who have experienced virologic failure on an NNRTI-containing regimen should not use etravirine in combination with only nucleoside/nucleotide reverse transcriptase inhibitors.
Safety and efficacy have not been established in treatment-naive patients.
Special attention should be given to accurate dose selection, transcription of the medication order, dispensing information, and dosing instructions to reduce the risk of medication errors, overdosing, and underdosing.
Safety and efficacy have not been established in pediatric patients less than 6 years of age.
No adjustment recommended.
Etravirine should be taken after a meal. The type of food does not affect the exposure to etravirine.
The etravirine tablet(s) should be swallowed whole with a liquid (such as water). Patients unable to swallow the etravirine tablet(s) whole may disperse the tablet(s) in a glass of water. The following instructions are recommended:
1. Place the tablet(s) in 5 mL of water, or at least enough liquid to cover the medication.
2. Stir well until the water looks milky.
3. If desired, add more water or alternatively orange juice or milk; the tablet(s) should not be placed in orange juice or milk without first adding water. Grapefruit juice, warm beverages (greater than 40 degrees Celsius), and carbonated beverages should be avoided.
4. Drink it immediately.
5. The glass should be rinsed with water, orange juice, or milk several times and each rinse should be completely swallowed to ensure the entire dose is consumed.
Etravirine should always be used in combination with other antiretroviral agents.
