Why is Ortho Evra prescribed?

Ortho Evra is a contraceptive skin patch. It contains estrogen and progestin, the same hormones found in many birth control pills. Fertility depends on regular fluctuations in the levels of these hormones. Contraceptives such as Ortho Evra reduce fertility by eliminating the fluctuations. Once applied to the skin, the Ortho Evra patch releases a steady supply of estrogen and progestin through the skin and into the bloodstream.
