Estrostep , a combination chemically known as norethindrone, ethinyl and ferrous fumarate, is a combination of estrogen, progestin and iron that is used to prevent pregnancy or treat moderate to severe acne.

This birth control pill works by preventing the full development of a womans egg every month. As a result, the egg and sperm fail to meet and fertilization is avoided.

Estrostep comes as tablets in a disposable package, to be taken by mouth once a day, at the same time.

Common side effects from Estrostep are decreased or prolonged bleeding at menses, breast tenderness, vomiting, nausea and changes of weight.

Estrostep is also used to regulate the menstrual cycle and other medical conditions, as suggested by your doctor.
