What is Depo-Provera®?
Depo-Provera® is a birth control method for women. It is made up of a hormone similar to progesterone and is given as a shot into the woman's arm or buttocks. Each shot provides protection against pregnancy for up to 14 weeks, but the shot should be received once every 12 weeks. Depo-Provera does not protect against sexually transmitted diseases.
Where can I get Depo-Provera?
This is a prescription medication and must be ordered by a doctor or nurse practitioner. The injection is usually given in the office by a nurse. There is a different brand that can be administered by patients at home, called Depo-subQ Provera 104. Patients will need teaching on how to give themselves the shots before they can start doing this on their own.
How is Depo-Provera used?
The first injection is often given within 5 days of the beginning of your menstrual period. However, it can be given at another time if you and your doctor can be confident that you are not pregnant. Once the shot has been given, no additional steps are needed to prevent pregnancy. With Depo-Provera, you must receive another shot once every three months (12 weeks) to remain fully protected. You should not be more than 2 weeks late coming in for the Depo-Provera shot, otherwise you can get pregnant. However you can come in earlier than 12 weeks if needed.
How soon does it work?
Protection begins immediately after the first shot if given during a menstrual period. If given at another time in the cycle, wait a week to ten days before having intercourse without a condom.
How effective is Depo-Provera?
Although it used to be quoted that Depo-Provera is 99% effective in preventing pregnancy, it turns out that there can be anywhere between 6-12 accidental pregnancies in every 100 Depo users each year. Women at greatest risk of accidental pregnancy include younger women such as adolescents. Much of this may have to do with human error, such as forgetting to come in for the shots on time. IUDs (brand names ParaGard®, Mirena®, Skyla®) and implants placed in the upper arm (Nexplanon®) are considered to be the most effective forms of contraception, and are 99% effective.
