Birth control pills contain one or two types of synthetic female hormones, estrogen and-or progestin. Similar hormones are normally made by the ovaries. Besides preventing pregnancy, there are other uses of oral contraceptives. Certain pills are also approved for the treatment of acne and premenstrual dysphoric disorder. Oral contraceptives that are only approved for preventing pregnancy can also be used off-label for treating other conditions. Some common off-label oral contraceptive uses include the treatment of polycystic ovarian syndrome, perimenopause, and endometriosis.
