The contraceptive injection does what it says on the tin! It’s an injection containing progestogen hormone given into a woman’s muscle which slowly releases into the body. The contraception injection works to stop a woman’s ovaries releasing an egg. Some women are offered a similar injection that they can use at home.
If used correctly (no missed injections) the contraceptive injection is over 99% effective (this means that each year less than one woman in a 100 will get pregnant using this method to prevent pregnancy).
It doesn’t interrupt sex.
The contraceptive injection can give women some protection against cancer of the uterus.
It can help reduce heavy, painful periods.
The contraceptive injection lasts for 12 weeks (3 months).
Some women may experience irregular bleeding.
Once the injection has been given, it cannot be removed from the body.
Some women may experience a small amount of weight gain whilst on the contraceptive injection.
