Ortho Evra is a contraceptive that is administered in the form of a skin patch. The active ingredients in Ortho Evra are the hormones estrogen and progestin, the same hormones that comprise a number of birth control pills. Like birth control pills, Ortho Evra can have side effects. People on the Ortho Evra patch may experience these side effects in varying degrees. However, many of the side effects are minor and can be temporary, so they continue to use the patch. That being said, there are certain individuals who have preexisting medical or mental conditions that may be exacerbated by the use of Ortho Evra.
