What is Depo-Provera and how is it used?
Depo-Provera is an injectable progestin (hormone) that acts similarly to other progestin-only contraceptives. Depo-Provera works by preventing the ovaries from releasing an egg and by changing the cervical mucus, thus helping to prevent the sperm from reaching the egg. One injection in the arm or buttocks provides 12 weeks of protection so you must return to your health care provider every 12 weeks for another injection. Depo-Provera can be used safely and effectively as a contraceptive by most women. Depo-Provera does not protect against STDs so always use a condom.
