Contraceptive patch

Contraceptive Patch

The Contraceptive Patch (pronounced: /kɒnˈtræsɪptɪv pætʃ/) is a transdermal patch applied to the skin that releases synthetic estrogen and progestin hormones to prevent pregnancy.

Etymology

The term "contraceptive" is derived from the Latin words "contra," meaning against, and "conceptus," meaning conception. The word "patch" comes from the Old French "pache," meaning a piece or a spot.

Usage

The Contraceptive Patch is used by adhering it to the skin once a week for three weeks, with the fourth week being patch-free. This method allows the hormones to be absorbed directly into the bloodstream through the skin.

Effectiveness

When used correctly, the Contraceptive Patch is over 99% effective at preventing pregnancy. However, its effectiveness can decrease if the patch falls off and is not replaced within 24 hours, or if the user is taking certain medications.

Side Effects

Possible side effects of the Contraceptive Patch include skin irritation at the site of application, nausea, headache, and changes in menstrual bleeding.
