{{#invoke:redirect hatnote|redirect}} {{#invoke:Infobox|infobox}} A contraceptive patch is a transdermal patch applied to the skin that releases synthetic estrogen and progestin hormones to prevent pregnancy. They have been shown to be as effective as the combined oral contraceptive pill with perfect use, and the patch may be more effective in typical use.<ref name=CT>{{#invoke:citation/CS1|citation |CitationClass=book }}</ref><ref>Contraceptive Technology, Chapter 12, Contraceptive Patch and Vaginal Contraceptive Ring, by Kavita Nanda, page 272</ref>

The only currently available contraceptive patches are Ortho Evra, marketed in the United States by Ortho-McNeil, and Evra, marketed in Canada by Janssen-Ortho and in the United Kingdom and other countries by Janssen-Cilag. The patches are packaged in boxes of three and are only available by prescription. The contraceptive patch is often informally referred to as "the Patch."
