Injections
A prick that prevents pregnancy? Find out more here.
What is it?
A hormonal method of contraception that works in the same way as the progestogen-only pill but which also prevents ovulation. There are two brands available in the UK, but each provides pregnancy protection with a single jab. The contraceptive effects of the Depo-Provera injection last for three months, while a Noristerat jab lasts for two months. Both methods are over 99% effective.
How is it taken?
The injection should be carried out by your doctor within five days of menstruation, and is effective immediately.
Benefits
- Safe, effective, and a useful alternative for women who routinely forget to take the combined pill or progestogen-only pill;
- Fuss-free sex;
- Can be used by breastfeeding mothers;
- May help ease pre-menstrual symptoms or period pains;
Drawbacks
- Protects against pregnancy, but not sex infection. Always use a condom for maximum risk reduction;
- Disruption to menstrual bleeding. This can mean longer periods or none at all;
- Small risk of headaches, moodswings, acne and weight gain. If anything like this does kick in, it may last until the contraceptive effects wear off (i.e. two to three months).
- Fertility can take up to a year to return after use.
Not suitable for
- Women who are pregnant;
- Women with breast cancer or undiagnosed breast lump;
- Women with liver disease.
