Contraception by Injection


How it works

An injection containing the female hormone progestogen. An injection is given by a health care professional approximately every 12 weeks. The hormone progestogen is released very slowly into the body to prevent ovulation (an egg being released)


This method is very effective once taken correctly at the correct time intervals.

Does not interrupt sex Doesn't protect from STIs
Suitable for those who can't take other hormonal contraception Can only be used for 2years as it is associated with osteoporosis if used long term.
Don't need to remember pills Periods can take a while to come back after stopping the injections
