What the FDA labels say about taking them together

Ethinyl estradiol/norelgestromin's FDA label of April 16, 2026 names nevirapine in its drug interactions section; the nevirapine label PlainMeds reads does not name ethinyl estradiol/norelgestromin. The ethinyl estradiol/norelgestromin label: “… inhibitors, and some non-nucleoside reverse transcriptase inhibitors (e.g., nevirapine).”
