A Depo injection is primarily a type of contraceptive injection. The most well-known brand name is Depo-Provera, which contains the hormone progestin, specifically medroxyprogesterone acetate. This injection is administered every three months and works by suppressing ovulation, preventing the ovaries from releasing an egg.
