What is it?

The hormonal injection contains the hormone progestogen. It is given by a doctor or nurse once every 12 weeks.

How reliable is it?

With “perfect use” the injection is more than 99% effective meaning that less than one woman in every 100 who use it will get pregnant in a year.1

However, because with every day “typical use” it is not always used perfectly, up to 6 women out of 100 in a year will become pregnant.1
