Ortho Evra is a contraceptive skin patch containing a combination of female hormones (ethinyl estradiol and norelgestromin) that prevent ovulation (the release of an egg from an ovary). This medicine also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.

Ortho Evra skin patches are used as contraception to prevent pregnancy.
