The patch is a combination method containing both progestin and estrogen, similar to many birth control pills and the Nuvaring. This form of birth control only requires weekly action, as opposed to daily with the pill. The patch is a small band aid-like sticker that is very effective if used correctly. Ortho Evra was approved by the FDA in 2002 after extensive testing. More than 70,000 birth control patches were clinically tested worldwide in more than 30,000 people.
