Sayana Press injection

The contraception injection is the only form of injection which may cause weight gain in some women. Whilst this might sound alarming, it's important to note that this doesn't happen for most women. Take a look at our user's reviews above to find out how our community report on how the Sayana Press injection affects their weight. You can also find out more in our guide to contraception and weight.

The time it takes to fall pregnant after the Sayana Press injection varies for different women. This is because many factors affect fertility. According to research, 80% of women will get pregnant within a year of stopping Sayana Press. Find out more in our guide to contraception and return to fertility.

Sayana Press does not cause infertility. It can however impact your return to fertility after stopping, with delays of up to a year for some women. When we talk about a ‘return of fertility’ what we really mean is a return to a woman’s ‘usual’ fertility. This does not automatically mean that a year after stopping the injection a woman will be fertile or easily able to get pregnant. Her fertility will still depend on her age, genetics and any underlying medical problems. Find out more in our guide to Sayana Press and fertility.

Sayana Press is injected beneath the skin at the front of the thigh or abdomen and the first injection is typically done by your doctor. It’s possible for you to be taught how to inject Sayana Press yourself at home but not all GPs and clinics currently offer this. You'll need to have Sayana Press injected once every 13 weeks to stay protected against pregnancy. After the injection has been given you only need to go back to your doctor or nurse if you have any problems, or annually because you will be given one year supply. The injection can’t be removed from your body. If you have any side effects, you have to be prepared for them to continue during the 13 week period, and possibly afterwards.

The Sayana Press injection is very safe. There are however some small risks associated with the injection. The injection can cause thinning of the bones because it affects your natural oestrogen levels. Thinning of the bones may be more of a problem if you already have risk factors for osteoporosis – if this is the case your doctor or nurse will probably advise you against the injection. In very rare cases you can have an allergic reaction to the injection and there is also a small risk of a reaction at the site the injection is given, which may cause irritation, swelling or a scar. Evidence has also shown that the Sayana Press injection is associated with an increase in weight in some people. For more information on this, you can read our guide to contraception and weight. It's important to remember that it does not protect you from STIs.;
