Injection

THE BIRTH CONTROL INJECTION

ONE SHOT TO COVER YOU FOR UP TO THREE MONTHS.

IT JUST TAKES A MOMENT

The birth control injection is a shot of hormones – either a progestin alone, or a progestin and estrogen – that stop the ovaries from releasing eggs and thicken the cervical mucus to make it harder for sperm to move. It works much in the same way as other hormonal birth control methods, such as the pill, except one shot will have an effect for one to three months, depending on the type. This means, however, that its effects are not reversible once it has been administered.

Once you have decided that the birth control 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 – either every month, every two months or every three months – to make sure the injection is at its most effective. If and when you want to return to fertility, it’s worth consulting your doctor or nurse as it may be some time before you can get pregnant.

Is It Okay?

CONSIDER THIS

It’s not uncommon to be fearful about having a needle. But as the injection must be re-administered monthly or quarterly, this contraceptive is best for individuals who are comfortable with committing to the procedure. 

CONSIDER THIS

This approach is entirely self-directed, and requires a lot of planning and tracking. Those who wish to avoid unplanned pregnancy should use a hormone-free barrier method when ovulating, or if menstrual cycles are irregular. For protection from STIs, condoms must be used.
