Sayana Press Injection

Sayana Press should be injected once every three months (12-13 weeks). Once it has been injected it reduces the chances of pregnancy by preventing an egg from fully developing and being released from the ovaries during your menstrual cycle. If an egg isn’t released, it can’t become fertilised.

Unlike condoms, Sayana Press has no effect on preventing STIs.

Once you’ve used it Sayana Press can prevent pregnancy for up to 13 weeks.

Sayana Press should be suitable for most women who have started their period. However, contraceptive injections can be dangerous depending on your medical history, for example having had blood clots or breast cancer. Make sure to tell us all relevant details during your consultation and we will make sure Sayana Press is right for you.

You will only be allowed a prescription for Sayana Press if:

• You have used Sayana Press before

• You have previously been shown how to use Sayana Press

Remember to keep your pouch at room temperature, shake before use and throw your needle away safely afterwards (use a sharps bin and dispose of it via your local council once it’s full).

When Sayana Press is used it can cause side effects. The most common can include weight gain, mood changes and changes to your period like pains or changes to regularity. Around 60% of women stopped experiencing bleeding during their period after a year.

Contraceptive injections can also negatively affect bone density, though this tends to stabilise as you continue to use it and can recover after you stop taking Sayana Press.

If you are concerned about side effects or begin experiencing them, talk to your GP.
