The birth control drug Ortho Evra®
(norelgestromin/ethinyl estradiol) is unique in that it comes in patch form, rather than the pill that many women are used to. It works just like oral contraceptives
, however, preventing pregnancy by stopping ovulation and changing the cervical mucus and uterine lining.
When using Ortho Evra, a new patch is applied once a week for the first three weeks of a cycle; no patches are worn during the last week, which allows for a menstrual period. You can wear the patch on the upper outer arm, the upper torso (not on the breasts), the stomach, or the buttocks.
