What are they?

A shot, usually in the upper bottom, with the hormone progesterone  will give you contraceptive cover. 

There are two types of injectable contraceptive - Depo-Provera which lasts for 12 weeks, and Noristerat which lasts for eight weeks.

How they work

The hormone progestogen stops ovulation (release of an egg) and thickens the mucus around the cervix, which makes it difficult for sperm to get into the womb. Not having periods makes the womb lining thin and unfriendly. 

Where can you get them from?

Injections are available from the doctor’s or family planning clinic. Remember to get your next shot!

The contraceptive injection is not suitable for all women. A doctor or nurse will need to know about a woman's medical history and any illnesses suffered by immediate members of her family, to find out if there are any medical reasons why it might not be suitable.

The failure rate

Injectable contraception is 99% effective. Follow-up injections must be given on time. 

Some prescribed and complementary medicines make the injection less effective.

• No periods (yay!)
• Does not interrupt sex - No messing round when it comes to the big moment.
• Women do not have to remember to take a pill.
• May protect against cancer of the womb.

• Can take a year or more after stopping the injection for regular periods to return.
• No protection against STIs.
• Periods may be irregular or stop altogether.
• As the hormone is injected into the body, any side effects may continue for as long as the injection lasts, and sometimes longer.
• Can cause headaches and skin problems.
