Depo-Provera® Birth Control Injection
Convenient, private birth control without a daily pill. Learn how the Depo-Provera injection works, how often you need it, potential benefits and side effects, and whether injectable contraception may be right for you.
Depo-Provera is a progestin-only contraceptive injection designed to help prevent pregnancy for about 13 weeks.
Individual timing and eligibility should be discussed with your healthcare professional.Birth control designed around your schedule
Depo-Provera is a hormonal birth control injection containing depot medroxyprogesterone acetate, commonly called DMPA. Instead of taking a birth control pill every day, the injection provides contraceptive protection for approximately 13 weeks.
The injection is a progestin-only contraceptive. It works primarily by preventing ovulation and also changes cervical mucus and the lining of the uterus in ways that make pregnancy less likely.
For people who prefer not to remember a daily pill, an injectable method may offer a convenient option. Choosing contraception is personal, however, and the best method depends on your health history, preferences, reproductive goals, and individual risk factors.
Depo-Provera quick facts
Here are some of the key things to know before considering the birth control injection.
Progestin-only
Depo-Provera contains depot medroxyprogesterone acetate, a progestin hormone.
About 13 weeks
The injection is designed to provide contraceptive protection for approximately 13 weeks.
No daily pill
You do not need to remember a birth control pill every day while using the injection.
Bleeding may change
Irregular bleeding or spotting can occur, particularly during the first months of use.
How does the Depo-Provera shot prevent pregnancy?
Depo-Provera uses a progestin hormone to prevent pregnancy through several contraceptive effects.
Suppresses ovulation
The primary contraceptive action is suppression of ovulation, meaning an egg is generally not released from the ovary.
Changes cervical mucus
The medication thickens cervical mucus, making it more difficult for sperm to travel through the cervix.
Changes the uterine lining
Progestin also affects the lining of the uterus as part of its contraceptive action.
Why some women choose the birth control injection
Depo-Provera may appeal to people looking for a longer-acting, private contraceptive option without taking medication every day.
No daily pill
You do not have to remember a contraceptive pill every day.
Convenient schedule
The injection is administered approximately every three months rather than every day.
Private contraception
There is no contraceptive device placed in the uterus and no daily medication to manage.
May reduce menstrual bleeding
Some users eventually experience much lighter periods or no menstrual bleeding.
Possible Depo-Provera side effects
Hormonal contraception can affect each person differently. Understanding possible changes can help you make an informed decision with your healthcare professional.
One of the most common considerations with Depo-Provera is a change in menstrual bleeding. Spotting, irregular bleeding, prolonged bleeding, and eventually absent periods can occur.
Irregular bleeding or spotting
Changes in menstrual periods
Headaches
Weight changes
Changes in mood may occur
Bone mineral density can decrease during use
Will Depo-Provera stop my period?
Your menstrual pattern may change after starting Depo-Provera. Irregular bleeding and spotting are common, especially earlier in treatment.
With continued use, some people experience progressively less menstrual bleeding and eventually may have no periods. The American College of Obstetricians and Gynecologists notes that rates of amenorrhea increase with longer use and may approach approximately 68–71% at two years.
Depo-Provera and bone mineral density
Depo-Provera use is associated with a decrease in bone mineral density. This is an important consideration when discussing whether injectable contraception is appropriate for you.
Evidence reviewed by ACOG indicates that bone mineral density generally recovers after discontinuation, although the amount and speed of recovery can vary.
ACOG states that concerns about bone mineral density alone should not automatically prevent prescribing or continuing DMPA, but patients should receive individualized counseling about benefits and risks.

What happens when you stop Depo-Provera?
Depo-Provera is reversible contraception. If you decide that you want to become pregnant, discuss your plans with your healthcare professional.
Unlike an IUD or implant, there is no device that needs to be removed. The medication gradually wears off after the injection, and the return of ovulation can take longer than with some other reversible contraceptive methods.
If pregnancy is something you may want in the near future, timing your contraceptive choice around your reproductive goals is an important part of the conversation.
Does Depo-Provera protect against STIs?
No. Depo-Provera helps prevent pregnancy but does not protect against sexually transmitted infections.
If STI protection is needed, condoms can be used in addition to hormonal contraception.
Depo-Provera vs. other birth control methods
There is no single contraceptive method that is best for everyone. Your healthcare professional can help compare options according to your priorities.
