What is the contraceptive injection?
The contraceptive injection contains a progestogen hormone. This is injected into a muscle (Depo-Provera® injection) or the skin (Sayana Press® injection) and is released very slowly into your body. It will protect you from pregnancy for 13 weeks.
The main way the injection works is to stop your ovaries releasing an egg (ovulation), thickening of the cervical mucus to prevent sperm reaching an egg and thinning of the lining of the womb to prevent a fertilised egg implanting.
You can get the injection free of charge from your GP or at Sandyford. All our clinics stock injections.
The doctor or nurse will consider your medical history to make sure you can have an injection and tell you about any possible side-effects. If you have any questions ask the doctor or nurse.
The injection protects you from pregnancy but not sexually transmitted infections. You must also use condoms to help protect against infections.
You do not need to have a vaginal examination or a cervical screening test to have a contraceptive injection.
How effective is it?
Contraceptive use can either be perfect (always correct) or typical (more accurate, as it’s sometimes difficult to use contraception correctly every time). With typical use of the combined pill, approximately 3 in 100 people become pregnant within the first year of use.
