ModerateAmpicillin may make birth control pills like Ethinyl Estradiol + Gestodene work less well. If you take them together, the pill may not protect you from pregnancy as reliably as it normally would.
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.
