What the FDA labels say about taking them together
Ethinyl estradiol/levonorgestrel and etravirine
Ethinyl estradiol/levonorgestrel's FDA label of August 27, 2026 names etravirine in its drug interactions section; the etravirine label PlainMeds reads does not name ethinyl estradiol/levonorgestrel. The ethinyl estradiol/levonorgestrel label: “… inhibitors and with other non-nucleoside reverse transcriptase inhibitors (e.g., etravirine).”
