What is the Injection?

The contraceptive injection protects you against pregnancy for 8 weeks or 12 weeks; depending on the type you use.

There are two versions:

Depo-Provera; which lasts for 12 weeks and is the most popular;
Noristerat; which lasts for 8 weeks.


How it works

The injection contains progestogen. Progestogen thickens the mucus in the neck of the womb; which stops sperm reaching an egg. It also thins the lining of the womb so that an egg cannot implant itself there.

In most women; the injection stops ovulation (the release of an egg).
