Injections
This is an injection that releases the hormone progestogen into your body.
Contraceptive injections do NOT protect against sexually transmitted infections.
The injection works like the pill but lasts for 12 weeks. It is given in your arm or buttock muscles by a GP or nurse. It is usually administered during the first five days of a period and is available on prescription only.
Advantages of Injections:
- It is very reliable and is 98% effective in preventing pregnancy if you get the injections at the right time.
- Injections offer some protection against womb cancer.
- If you are vomiting or have diarrhoea it doesn't affect the contraceptive, unlike the pill.
- Medication doesn't interfere as much with the injection as with the pill.
- There is a lower risk of ectopic pregnancy or ovary cists.
However:
- Injections don't protect against sexually transmitted infections.
- You have to remember to have the injections on time every three months.
- Your periods can become irregular or stop.
- You might have bleeding between periods.
- Fertility and periods can be slow to return when you stop getting the injection.
- There might be side effects such as weight gain.
