Everything you need to know about contraceptive injections

The contraceptive injection or Depo-Provera is an intramuscular injection that is given every three months. It contains only progesterone and is 99.7% effective. What are the advantages, disadvantages, and risks of taking this contraceptive injection?

Advantages of the contraceptive injection

The contraceptive injection is less annoying because it does not require daily tasks. It requires only 4 injections per year. It is a very good method for women who cannot take estrogen. Even if a woman is breastfeeding her child, she can use it. Over time, the contraceptive injection reduces menstrual pain. In some cases, the pain can even be stopped.

Disadvantages of the contraceptive injection

The main disadvantage of this method is that it cannot be stopped abruptly. It is only discontinued when all the side effects have worn off, which is several months. Every three months, the injection must be done by appointment with a professional. A difference of a few days can reduce the effectiveness of the method by up to 94%.
