Depo Provera – or DMPA – is a reversible method of birth control that is also often referred to as the Depo Shot or the birth control shot.
There are currently two versions of Depo Provera: the Depo Provera injection and the Depo-subQ Povera 104 Injection. Both injections generally work the same – by releasing progestin medroxyprogesterone acetate and protecting you from pregnancy for a period of 11 to 14 weeks. You must receive either shot four times per year to maintain its effective rate.
Depo-subQ Provera 104 is the newer version of the Depo shot, and contains 31% less hormone than the original shot. As such, it’s possible that this newer version leads to fewer progestin-related side effects.
