Birth control is a way for men and women to prevent pregnancy. There are many different methods of birth control; some types also protect against sexually transmitted diseases, or STDs. Depo-Provera does not protect against STDs.
Depo-Provera is a birth control method for women. It is made up of a hormone similar to progesterone and is given as an injection by a doctor into the woman’s arm or buttocks. Each shot provides protection against pregnancy for up to 14 weeks, but the shot must be received once every 12 weeks to remain fully protected.
How Soon Does Depo-Provera Work?
Birth control with Depo-Provera begins immediately after the first shot if given within the first five days of your menstrual period.
How Effective Is Depo-Provera?
Depo-Provera is 99% effective in preventing pregnancy. Again, it does not prevent spreading of STDs. To help protect yourself from STDs, use a latex male condom each time you and your partner have sex.
