What Is the Birth Control Shot?
The contraceptive shot that clinics now give is called Depo-Provera. It is a shot that the woman gets every 12 weeks to keep from getting pregnant. The shot only has progestin in it, no estrogen.
The shot works well to prevent pregnancy. But it does not protect against HIV or other STDs. If you are having sex with someone who might give you an STD, use a condom.
