Contraceptive injection

Contraceptive injection 

  • This is an injection with one hormone.  
  • The contraceptive injection works like the contraceptive pill and makes sure that no eggs ripen. 
  • The contraceptive injection is as reliable as the contraceptive pill.  
  • The contraceptive injection contains sufficient hormone to protect you for three months against pregnancy.
  • If you want to use the contraceptive injection, you need a prescription.  
  • After you buy it at the pharmacist, a doctor can administer the injection.  
  • If you have any complaints or questions, it is best to consult a doctor.


How do you use the contraceptive injection?

  • The contraceptive injection is injected for the first time at the beginning of your period.  
  • Afterwards you get an injection every 3 months. 
  • The injection is always administered by a doctor.  
  • It is given in a muscle in the buttock, and the hormone is released gradually in the blood.

When are you protected against pregnancy?

  • If the first injection is given on one of the first five days of the cycle, the contraceptive injection is immediately reliable.  
  • The injection is repeated every twelve weeks.  
  • To guarantee the reliability, a maximum interval of 89 days is used (twelve weeks plus five days).  After this period the reliability drops quickly. 
  • It is important to get a new injection on time.


What do you notice of the contraceptive injection?

During the first months, your body has to get used to the hormones and there may be some side effects: 

  • nausea
  • headache
  • sore breasts
  • bleeding between periods  
  • mood changes 

These side effects usually disappear spontaneously.  If this is not the case, go and see a doctor. 
Some women gain some weight from the use of the contraceptive injection. 
Mainly in the beginning there can be frequent, irregular and slight loss of blood (bleeding between periods).  Afterwards half of the women stop menstruating.

When you stop with the contraceptive injection, your period will return.  It may take some time before your own cycle starts again and before you can become pregnant.


What are the risks of the contraceptive injection?

Always discuss your medical history with your doctor.  He or she can judge whether this is a suitable form of contraception for you.

  • It is not risky for your health if you use the contraceptive injection.  
  • Because you use hormones, it is better not to smoke.  
  • It is important to take enough calcium (milk, yoghurt, cheese, ...) and vitamin D (sun light).  This is to prevent osteoporosis.


Sickness and medication

Sickness and medication have no influence on the use of the contraceptive injection.
