Injectable Contraception

Over 99% effective once the injection is given regularly

Description

The injection contains the female hormone progestogen. An injection is given by a health care professional approximately every 12 weeks.

How it Works

The hormone progestogen is released very slowly into the body to prevent ovulation (an egg being released).
