Birth control is a way for men and women to prevent pregnancy. There are many different methods of birth control; some types also protect against sexually transmitted diseases, or STDs. Depo-Provera does not protect against STDs.
Depo-Provera is a birth control method for women. It is made up of a hormone similar to progesterone and is given as an injection by a doctor into the woman's arm or buttocks. Each shot provides protection against pregnancy for up to 14 weeks, but the shot must be received once every 12 weeks to remain fully protected.
Birth control with Depo-Provera begins immediately after the first shot if given within the first five days of your menstrual period.
How Effective Is Depo-Provera?
Depo-Provera is 99% effective in preventing pregnancy. Again, it does not prevent spreading of STDs. To help protect yourself from STDs, use a latex male condom each time you and your partner have sex.
Can Any Woman Use Depo-Provera?
Most women can use Depo-Provera. However, it is not recommended for women who have:
Unexplained vaginal bleeding
Are There Side Effects Associated With Depo-Provera?
Depo-Provera can cause a number of side effects, including:
Irregular menstrual periods, or no periods at all
Changes in appetite
Excessive growth of facial and body hair
Loss of bone mineral density
Most of the side effects are not common. Change in the menstrual cycle is the most common side effect. You may experience irregular bleeding or spotting. After a year of use, about 50% of women will stop getting their periods. Their periods usually return when they discontinue the shots.
Prolonged use of Depo-Provera may result in loss of significant bone mineral density, increasing the risk of osteoporosis. This risk is more likely for those who have been taking it for longer than two years, particularly when other risk factors for osteoporosis exist, such as family history and chronic alcohol and/or tobacco use. Although there are no studies to benefit its use, it is advised that all women on Depo-Provera get adequate calcium and Vitamin D (through diet and/or supplements) to help prevent osteoporosis.
Can I Become Pregnant After I Stop Using Depo-Provera?
With Depo-Provera, you could become pregnant as soon as three to four months after your last shot. However, it may take some women up to a year or two to conceive after they stop using this type of birth control. This time frame seems unrelated to how long you had been using Depo-Provera.
What Are the Advantages of Using Depo-Provera?
There are several advantages to using Depo-Provera:
You don't have to remember to take it every day or use it before sex.
It provides long-term protection as long as you get the shot every three months.
It doesn't interfere with sexual activity.
It's over 99% effective.
It's less expensive than the Pill.
What Are the Disadvantages of Using Depo-Provera?

You need to stop taking Depo-Provera several months ahead of time if you plan to become pregnant.
