Contraceptive injections are available as a type of hormonal contraceptive for women. Commonly known as Depo, Depo-Ralovera and Depo-Provera, contraceptive injections are considered as a long-acting option for hormonal control. The injections have artificial progesterone called Depot Medroxyprogesterone Acetate (DMPA). A single contraceptive injection is effective for 12 to 14 weeks.
Contraceptive or progesterone injections are administered either in the gluteus muscle, thigh muscle or the arm. They are normally given during the menstrual cycle in the first five days. The injections can only be administered by a health professional. The injection itself stops the ovaries from the process of ovulation. It also helps increase the thickness of cervical wall so that male discharge cannot enter the uterus during intercourse.
