I know that oral contraceptives are metabolized by P450 enzymes, so P450 inducers decrease the efficacy of the contraceptives, but I just read that "combined oral contraceptives (presumably the estrogen component) can impair the hepatic metabolism of several drugs, prednisone and glucocorticoids among them." Therefore, taking oral contraceptives with prednisone leads to increased prednisone side effects.
I never heard of contraceptives also being P450 inhibitors.. can someone please clarify?
