THE CONTRACEPTIVE INJECTION

One injection to cover you for up to three months.

IT JUST TAKES A MOMENT

the injection

The contraceptive injection is a shot of progestogen that thickens the cervical mucus to make it harder for sperm to move. It works much in the same way as other hormonal contraception methods, such as the progestogen-only pill, except one shot will have an effect for 8-13 weeks, depending on the type. This means, however, that its effects are not reversible once it has been administered.

 

Once you have decided that the contraceptive injection is right for you, your doctor or nurse will administer it. All you have to do is remember to return on time to get the next shot, every 8-13 weeks, to make sure the injection is at its most effective. Your normal level of fertility should return when the effect of the injection has worn off. But this can take a different amount of time in different women. So if you decide that you want to become pregnant it would be worth speaking with a healthcare professional.

HOW IT MEASURES UP

Typical use means how well the method works in real life and perfect use means how well a method works under 'perfect' or ideal conditions for example when there is no user error at any time.

EFFICACY WITH PERFECT USE

Given with a prescription and administered by a doctor or nurse, the contraceptive injection is very effective if it is administered on time every 8-13 weeks.
