What the FDA labels say about taking them together

Acetaminophen and ethinyl estradiol/levonorgestrel

Ethinyl estradiol/levonorgestrel's FDA label of August 27, 2026 names acetaminophen in its drug interactions section; the acetaminophen labels PlainMeds reads (4) do not name ethinyl estradiol/levonorgestrel. The ethinyl estradiol/levonorgestrel label: “Ascorbic acid and acetaminophen may increase plasma EE concentrations, possibly by inhibition of conjugation.”
