- More Information
Ortho Evra (Norelgestromin and ethinyl estradiol transdermal system) is used to prevent pregnancy. It is a small patch that can be worn on the belly, chest, buttocks, chest, or upper arm. Norelgestromin is a progestin and ethinyl estradiol is an estrogen. Estrogen and progestin are two female sex hormones. Norelgestromin and ethinyl estradiol contraceptive patch works by preventing the release of eggs from the ovaries (ovulation) and changing the cervical mucus and the lining of the uterus. The contraceptive patch is a very effective method of birth control, but it does not prevent the spread of AIDS and other sexually transmitted diseases.
