How does the Contraceptive Injection work?

Depot medroxyprogesterone acetate (DPMA) is a 150mg dose of the hormone progestogen. It works by preventing the ovaries from releasing an egg and thickens the cervical mucous, preventing sperm from accessing the uterus. Once you’ve had the Injection, it cannot be reversed. This means that if you experience negative side effects, you need to wait for it to wear off. It can also take up to 18 months for fertility levels to return to pre-injection levels.

Tip: Want to try depo, but scared of needles? Try listening to music through headphones before and during the injection; it helps keep your mind off the needle.
