Injectable hormonal contraceptive

Depo Provera® and Depo Ralovera® are brand names of synthetic hormones (progestogen) that can be given by injection every 3 months to prevent pregnancy. The hormone is slowly released into the body, and works in 3 ways:

• it stops the body releasing an egg each month
• it changes the lining of the uterus so a fertilised egg cannot grow
• it makes the mucous in the cervix thicker so sperm cannot get through

Things to consider

• It is very convenient as you only need 1 injection every 3 months.
• You need to go to your doctor or health service to have the injection.
• You need to remember to book regular appointments so that your injections are given in time.
• Once given, the injections cannot be reversed or cancelled – you just have to wait for the hormone to reduce over time.
• It contains no oestrogen, so may be safer for some people, including smokers and people who cannot take the pill.
• body weight, stomach upsets or medications do not reduce its effectiveness
• Many people stop getting periods after the first couple of injections.
• Irregular bleeding may occur after the first few injections.
• most people start having periods and become fertile again 4 to 8 months after their last injection, but it can take longer for some people.
• it does not protect against STIs.
