What is Depo-Provera (Medroxyprogesterone Acetate) used for?

Depo-Provera (Medroxyprogesterone Acetate) is a hormonal injection which is used to prevent pregnancy. It may be effective for up to 3 months. The active ingredient in this injection is similar to a naturally produced hormone known as progesterone. It works by preventing the release of an egg, while also making it more difficult for a fertilized egg to attach itself to the wall of the womb, and making fertilization of an egg more difficult.

How should I use Depo-Provera (Medroxyprogesterone Acetate)?

Depo-Provera (Medroxyprogesterone Acetate) is injected intramuscularly (into a muscle), by a physician or other health care professional, in a physician's office or other health care facility. This injection is normally administered at the start of a menstrual period. It is normally considered to be effective 24 hours after it has been administered. Your physician may tell you that it is effective in preventing pregnancy for 13 weeks after it has been injected. You may be told to schedule your next medical appointment earlier than necessary, as if you are unable to attend your appointment to receive your injection, you may still have time to receive your next shot. Patients who are more than one week late for their injection should be aware that a pregnancy may occur if they have unprotected sex.

  • Stomach cramps, nausea
