How an injectable works
The injection is usually administered in the arm, thigh or buttock by a trained provider.
It only takes a few minutes to have the injection. It can take up to 7 days before the injection starts to work if you have not previously used a contraceptive injectable. You can use a condom for those 7 days.
Depending on the type of injectable given, another injection will be required in 2-3 months times to continue being an effective contraceptive method.
If you have your first injectable on day 1 to 5 of a period, it will work straight away. At any other time, extra precautions, such as condoms or abstaining from sex will be required for 7 days.
If you've recently had an abortion, you can have an injectable following your treatment. It will be given to you during your treatment and will work straight away. It will then last a further 12 weeks before another injection is required.
