Depo-Provera® (depot medroxyprogesterone acetate) is an injectable birth control method for women. Commonly called the depo shot or birth control shot, this medication is injected into your arm or buttocks. It contains a type of progesterone hormone Depo-Provera® shots provide protection against pregnancy for up to 14 weeks — though you typically need to receive one shot every 12 weeks.
Although Depo-Provera® is effective at preventing pregnancy, it does not protect against sexually transmitted infections (STIs). It’s important to still use barrier protection (condoms) to prevent STIs.
The Depo-Provera® shot works by impacting ovulation — the part of the reproductive cycle when an egg is released from a woman’s ovary — and thickening your cervical mucus, which prevents sperm from successfully getting to the egg.
The shot is injected into your muscle (often your arm or buttocks) and needs to be provided on a schedule of approximately every 12 weeks or three months.
