Depo-Provera has a lab-made hormone and is a medication similar to the female hormone progesterone. Also known as a birth control shot, it’s in injection form given to women to prevent pregnancy and works as birth control.  This shot works for 90 days, unlike oral contraceptives, but the medication remains in the bloodstream for longer. It needs to be taken after every 90 days to prevent pregnancy, and it’s injected either in the upper arm or buttock, which is quite different from other types of birth control. If you’re pregnant, you shouldn’t take this drug because it can result in congenital disabilities.
