Depo-Provera contains only the hormone progestin. It prevents pregnancy in the same way as birth control pills.

How it works
Depo-Provera prevents ovulation, and thins the lining of the uterus and thickens the cervical mucous to block the sperm from entering.

How to use it
A syringe is injected into a large muscle, usually in the buttocks, every three months. If more than three months pass between two injections, you are not protected against pregnancy. You’ll have to use a condom until one week after the new syringe has been injected.

If the syringe is injected on the first or second day of a menstrual period, you are safe from day one. When starting outside of this time frame, you must wait until the eighth day before you are protected from pregnancy. The first week you will have to use an additional contraceptive.

Side effects
Depo-Provera does not increase the risk of blood clots and can be used by women who can’t use contraceptives containing estrogen. The syringe increases the risk of osteoporosis as an adult. It should therefore not be your first choice if you’re still growing.

Uncomfortable but harmless side effects:

  • Bleeding disorder/irregular periods
  • Headache
  • Dizziness
  • Mood swings
  • Pimples
  • Tender breasts
  • Decreased sex drive

Effectiveness
Used correctly, it is 99.7% effective against pregnancy.
