Grison Griseofulvin Norgestrel + Ethinyl Estradiol + Ferrous Fumarate
ModerateGriseofulvin can make this pill work less well. It may make your body clear the hormones in the pill (norgestrel and ethinyl estradiol) out of your system faster than usual. With less of the hormones left in your body, the pill may not protect you from pregnancy as well as it should. If you need to take both, talk to your doctor or pharmacist first.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
