CONTRACEPTIVE INJECTION
WHEN and HOW?
The contraceptive injection is injected every 1, 2 or 3 months (every 4 , every 8 or every 12 weeks), depending on the type. The contraceptive injection has an efficacy of 96-97% with typical use.
The timing of injections is not based on the monthly bleeding. It works similarly to the pill or the ring, except that you don't have to remember to take it every day or every week.
As with most contraceptives, they aren’t the ideal choice for everyone so getting advice from a professional is something we always recommend.

- Some injections must be given by a healthcare provider. The physician injects the contraceptive into the upper arm with a syringe.
- Also, there is a type of injectable contraceptive which you can inject yourself after you have been shown how to do it by a healthcare professional.

All important details about the contraceptive injection
The contraceptive injection is a shot that contains hormones, either a progestin alone, or a progestin and an estrogen together, that stop your body from releasing eggs and thickens the mucus at the cervix. You need one shot either once every month, once every two months or once every three months from a healthcare provider. However once injected, it is not reversible, i.e. in case of side effects it cannot be stopped.
The way it works is similar to the pill, or the ring, except you don’t have to remember to take it every day or week, but it probably isn’t the best choice for those scared of needles.
Firstly, you’re going to need to talk to your healthcare provider. As with most contraceptives, they aren’t the ideal choice for everyone so getting advice from a professional is something we always recommend. If you decide the contraceptive injection is a method, you’re interested in your healthcare provider will do it for you. Then, depending on the type of shot you get, you’ll just need to go back every 1, 2 or 3 months for another top up and you’ll be highly protected in between.
