The Contraceptive Injection

The contraceptive injection is a highly effective form of contraception if it is given regularly and is classed as a long-acting contraception or LARC. There are 2 types of injection which are both made from a very similar drug which is a type of progesterone and needs to be given every 13 weeks. One is called depo-provera (or depo for short) which requires a nurse of doctor to give it to you and the other is sayana press which you can give yourself. They work by stopping you producing and egg so work well at preventing pregnancy and with perfect use only 1 in 500 women get pregnant, sometimes we might forget to come on time for our injection so with typical use 6 in 100 might get pregnant using this method.

Advantages of taking the contraceptive injection

  • You do not have to remember to take something every day.
  • They are not affected by diarrhoea or vomiting or some medications that break down drugs quickly (enzyme inducers).
  • They can thin the lining down of the womb so that you periods may be lighter or stop.
  • They do not increase your risk of bloods clots or strokes so can be used if you smoke, are very over weight or have certain types of migraines.


  • Irregular or unpredictable bleeding.
  • Can increase weight.
  • Might affect skin, mood, sex drive and cause headaches but may also improve them.
  • May reduce thickness of bones whilst you are on it.
  • Can take a while for periods to return when the injection is stopped so you may not wish to use it if you are planning pregnancy soon.
