Depo-Provera® is a hormonal birth control method that contains a progestin. It does not contain estrogen. It is administered by a needle in the muscle of the arm or buttocks every 12-13 weeks. It is 99.7% effective in preventing pregnancy, but causes loss of bone density. Because of this, Depo-Provera® is usually only recommended for people who are unable to take other contraceptive methods. The injection should be used with condoms to prevent sexually transmitted infections (STIs). 1vial 1ml 150mg
