Contraceptive injection
This contraceptive contains hormones, but is an injection instead of a pill. The injection protects you against pregnancy for 3 months. It is very reliable.
How does it work?
The hormones in the contraceptive injection make sure that you don’t get pregnant. 1 injection protects you against pregnancy for 12 weeks (3 months).
What you need to know
- Ask your doctor if this injection is suitable for you.
- A doctor gives you the injection. So you have to go to a doctor or other healthcare provider for each injection.
- A contraceptive injection protects you for 12 weeks.
Where can you get the contraceptive injection?
