Ortho-Novum 10/11 (ethinyl estradiol and norethindrone) is a progestin/estrogen combined oral contraceptive used by women to prevent unwanted pregnancy.
It works mainly by preventing the release of an egg during your menstrual cycle. It also makes vaginal fluid thicker, which makes it impossible for sperm to reach an egg and changes the lining of the uterus to prevent attachment of a fertilized egg. As a result, it just passes out of the body.
Besides, this medicine may make your periods more regular, light and less painful, decrease the risk of ovarian cysts. It can also treat acne.
