DEPO-PROVERA®
Medroxyprogesterone acetate
Aqueous suspension injection 150 mg/mL
What Depo-Provera is used for
The active ingredient of Depo-Provera, medroxyprogesterone acetate, is a chemical similar to the natural hormone progesterone. Progesterone is produced by your ovaries during the second half of your monthly cycle.
There are several reasons why your doctor may have prescribed Depo-Provera for you.
Depo-Provera is used for the following reasons:
- Contraception - Depo-Provera is an injectable form of contraception. Each injection protects you from pregnancy for 3 months. Depo-Provera works by inhibiting the hormones that are needed for the release of the eggs from the ovaries.
- Endometriosis - Endometriosis is a condition in which cells from the lining of the uterus (womb) grow in places outside the uterus. During your period, these cells may grow and break down in the same way as those in the lining of the uterus. This causes pain and discomfort. Depo-Provera helps to stop the growth of the cells found outside the uterus.
- Cancer - Depo-Provera is also used in the treatment of certain types of cancer including cancer of the breast, kidney and endometrium (lining of the uterus). It works by inhibiting the growth of these types of cancer cells. Depo-Provera is not a cure for cancer.
Your doctor may have prescribed Depo-Provera for another purpose. Ask your doctor if you have any questions about why Depo-Provera has been prescribed for you.

How Depo-Provera is given
The amount of Depo-Provera and the number of injections that you receive will depend on the reason that your doctor has prescribed it.
The dose for contraception and for endometriosis is a lot less than for cancer.
Contraception
The recommended dose of Depo-Provera for effective contraception is 150mg every three months. This is given as an injection into the muscle of your upper arm or buttocks. Your doctor or a trained nurse will give the injection. The contraceptive protection of Depo-Provera starts as soon as you have the first injection. It is important that you make arrangements to return to your doctor every three months, for your injections, to ensure that pregnancy is prevented. If you are using Depo-Provera as a contraceptive for the first time, your first injection should only be given during the first 5 days after the start of your normal monthly period. If you are using Depo-Provera as a form of contraception after the birth of your baby and if you are not breast-feeding, the first injection should be given within 5 days after the baby is born. If you are breast-feeding the first injection should be given 6 weeks after the baby was born, after your doctor has checked that you are not pregnant. If the time between your injections is greater than 13 weeks, your doctor will need to check that you are not pregnant before they give you another injection.
Endometriosis
The usual dosage is either 50mg weekly or 100mg every two weeks. This is given as an injection into the muscle of your upper arm or buttocks. Treatment for endometriosis is usually for at least 6 months.
Endometrial and Renal Cancer
The initial dose range of Depo-Provera is 500 to 1000mg. This is given as a weekly injection into the muscle of your upper arm or buttocks. There may be further treatment with an injection of 500mg a week or less. Your doctor will determine how much you will receive and how long you should continue to receive the injections.
Breast Cancer
The usual dosage for breast cancer is 500mg every day for 4 weeks. This is given as an injection into the muscle of your upper arm or buttocks. After the first 4 weeks, Depo-Provera is then given as a twice-weekly injection of 500mg. Your doctor will determine how much you will receive and how long you should continue to receive the injections.
Overdose
Overdose is unlikely as treatment will be given by your doctor or a health professional. Ask your doctor or pharmacist if you have any concerns.
While you are using Depo-Provera
Things you must do
If you become pregnant while using Depo-Provera, tell your doctor. (The chance of falling pregnant while using Depo-Provera, as a contraceptive, is very low).
If you have a sudden partial or complete loss of vision or sudden onset of double vision or migraine while you are taking Depo-Provera, tell your doctor immediately.
Tell all doctors, dentists, and pharmacists who are treating you that you are using Depo-Provera, particularly if you are about to have any pathology tests (e.g. blood or urine tests). Depo-Provera may interfere with the results.
If you are about to be started on any new medicine, tell your doctor or pharmacist that you are using Depo-Provera.
Things to be careful of
Be careful driving or operating machinery until you know how Depo-Provera affects you. Depo-Provera generally does not cause any problems with your ability to drive a car or operate machinery, However, Depo-Provera may cause dizziness, drowsiness or fatigue in some people.

Side effects

Most women using Depo-Provera for contraception experience changes in their normal monthly period. This includes irregular or unpredictable bleeding or spotting, or rarely, heavy or continuous bleeding. If abnormal bleeding continues or is severe, see your doctor immediately.
With continued use of Depo-Provera, it is usual for vaginal bleeding to decrease. Your periods may stop completely.
When you stop using Depo-Provera, your periods will return. However, this may take up to 18 months. Most women find that it takes about 10 months after their last injection to become pregnant. The length of time that you use Depo-Provera does not affect the time it takes for you to become pregnant.
