Description: The contraceptive patch looks like a square 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.

Considerations: It offers no protection from sexually transmitted infections and or HIV/AIDS

Availability: It must be prescribed by a doctor or a family planning clinic.

Effectiveness: When used correctly, the contraceptive patch is about 99% effective as birth control except for women weighing 198 pounds or more, where it is only about 92% effective.
