Contraceptive patches

Contraceptive patches are small, adhesive patches worn on the skin that release hormones to prevent pregnancy. They work by delivering estrogen and progestin, which stop ovulation (the release of eggs) and make it harder for sperm to fertilize any eggs that may be released. Patches are typically replaced weekly for three weeks, followed by a week without a patch to allow for a menstrual-like withdrawal bleed. They are a convenient and effective form of birth control, suitable for many women. However, it's important to use them as directed for maximum effectiveness.
