What the FDA labels say about taking them together
Ethinyl estradiol/norelgestromin and etravirine
Ethinyl estradiol/norelgestromin's FDA label of April 16, 2026 names etravirine in its drug interactions section; the etravirine label PlainMeds reads does not name ethinyl estradiol/norelgestromin. The ethinyl estradiol/norelgestromin label: “… inhibitors and with other non-nucleoside reverse transcriptase inhibitors (e.g., etravirine).”
