Depo-Provera Injection

Contraception

The Depo–provera shot contains progesterone which prevents pregnancy by preventing ovulation and by thickening the mucus at the cervix which blocks the sperm from entering.

The shot is given in the office every 12 weeks. The first shot is given when you start your period. Only about 6 women in 100 get pregnant on the shot.


Pros of Depo

  • It lasts for 12 weeks
  • You can use this method without others knowing
  • Your periods may be less painful
  • You may not have a period at all
  • It is safe while breastfeeding

Cons of Depo

  • It causes changes in your periods
  • You may have other side effects that will last the entire 12 weeks until the shot wears off.
  • You have to go back to the Doctors office every 12 weeks for another shot.
  • Some women may gain weight with the shot.

What if I am late for my shot?

Use a backup method such as condoms to prevent pregnancy and talk to your provider to find out when to reinitiate the Depo shot.
