Contraceptive patch What is it? The Contraceptive Patch looks like a square plaster/band-aid. It is applied to the abdomen, buttocks, upper arm, or upper torso. The Patch is changed each week for a schedule of 3 weeks on and 1 week off.
It works by slowly releasing a combination of oestrogen and progestin hormones through the skin. These hormones prevent ovulation (release of an egg from the ovary) and thicken the cervical mucus, creating a barrier to prevent sperm from entering the uterus.
