The Depo-Provera shot is a highly effective birth control method. Women who use it correctly have a risk of pregnancy thatâs less than 1 percent. However, this percentage increases when a woman doesnât receive the shot at the recommended times.
A Stacy Wiegman, PharmD , Pharmacy, answered. The Depo-Provera birth control shot works extremely well, as long as you keep getting your shots every three months. Depo-Provera is more than 99% effective, which means that it is more reliable than most other types of birth control. On average, only one woman in 100 who uses Depo-Provera gets pregnant. Talk with your doctor or pharmacist about the safety and effectiveness of this and other types of birth control.
