Generic Name: medroxyprogesterone acetate
Product Name: Provera

Indication: What Provera is used for

Provera is used to treat:

  • Endometriosis – a condition in which tissue similar to the lining of the uterus (womb) grows outside the uterus, causing pain and bleeding. Provera helps to stop the growth of this tissue;
  • Secondary amenorrhoea (a lack of menstrual periods not due to pregnancy); Provera, with or without an estrogen, helps to re-establish a regular menstrual cycle;
  • Abnormal bleeding from the uterus, when the lining of the uterus breaks down during the menstrual cycle rather than at the end, resulting in vaginal spotting or bleeding. Provera helps to re-establish a regular menstrual cycle;
  • Certain types of cancer including cancer of the breast, kidney and endometrium;
  • Provera, in combination with an estrogen-containing medicine, is used to relieve symptoms of menopause in women with an intact uterus. This is called hormone replacement therapy (HRT). Provera is used to protect the lining of the uterus while the estrogens relieve the symptoms of menopause. Provera is not suitable as an HRT treatment in women who have undergone a hysterectomy.

Ask your doctor if you have any questions about why Provera has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is available only with a doctor’s prescription.

Action: How Provera works

Provera is a progestogen that comes from progesterone, a natural sex hormone. Provera works in a similar way to progesterone.

Medroxyprogesterone acetate (MPA) is a progestational agent. When administered in recommended doses to women with adequate endogenous estrogen, it transforms proliferative into secretory endometrium. MPA may inhibit gonadotrophin production, which in turn prevents follicular maturation and ovulation.

Like progesterone, MPA is thermogenic. At the very high dosage levels used in the treatment of certain cancers (500 mg daily or more), a corticoid-like activity may be manifest.

The active ingredient in Provera tablets is medroxyprogesterone acetate.

Provera 2.5 mg, 5 mg, 10 mg tablets also contain the inactive ingredients lactose monohydrate, sucrose, maize starch, liquid paraffin, purified talc, calcium stearate, sunset yellow FCF (5mg ), and indigo carmine (5 mg).

Provera 10 mg tablets do not contain colouring agents.

Provera 100 mg, 200 mg, 250 mg, 500 mg tablets also contain the inactive ingredients sodium starch glycollate, microcrystalline cellulose, maize starch, gelatin, docusate sodium, macrogol 400, sodium benzoate, isopropyl alcohol, and magnesium stearate.

Provera 100 mg, 200 mg, 250 mg, 500 mg tablets do not contain colouring agents.

If you are not sure whether you should start taking Provera, contact your doctor.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Before prescribing Provera for you, your doctor may conduct a physical examination which may include breast examinations or a mammogram and a PAP smear.

Tell your doctor if you have or have had any of the following medical conditions:

  • Heart problems;
  • Kidney problems;
  • Migraine;
  • Unusual or irregular vaginal bleeding;
  • Genital or breast cancer;
  • Epilepsy;

If you have not told your doctor about any of the above, tell them before you start taking Provera.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including medicines you buy without a prescription from a pharmacy, supermarket or health food shop.

Some medicines may interfere with Provera. This includes aminoglutethimide, a medicine used to treat breast cancer. This medicine may affect how well Provera works. You may need different amounts of your medicine or you may need to take different medicines. Your doctor will advise you.

Your doctor or pharmacist may have more information on medicines to be careful with or avoid while taking Provera.

How to take Provera

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained here.

If you do not understand the instructions on the label or here, ask your doctor or pharmacist for help.

How much to take

Your doctor will tell you how much Provera to take. This will vary depending on the condition for which you are being treated. Provera should be used at the lowest effective dose to treat your condition.

Your doctor may tell you to take Provera every day or in repeating cycles with a break in between.

How to take Provera

Swallow the tablets whole with a full glass of water.

When to take Provera

Take Provera at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.

How long to take it

Continue taking your medicine for as long as your doctor tells you. Your doctor will prescribe Provera for the shortest duration necessary to effectively treat your condition.

If you forget to take Provera

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking Provera as you would normally.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist. If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at your nearest hospital if you think you or anyone else may have taken too much Provera. Do this even if there are no signs of discomfort or poisoning. You may need medical attention.

While you are taking Provera

Things you must do

Take Provera exactly as your doctor has prescribed.

Tell your doctor if you think you may have become pregnant during treatment. Provera should not be used during pregnancy.

Tell your doctor immediately if you have sudden partial or complete loss of vision or sudden onset of double vision or migraine. You will need to be examined and may need to stop taking your medicine.

Tell all doctors and pharmacists who are treating you that you are taking Provera.

If you are about to start taking any new medicines, tell your doctor and pharmacist that you are taking Provera.

If you are going to have any laboratory tests, tell your doctor that you are taking Provera. Provera may interfere with the results of some tests.

Tell your doctor if you feel that Provera is not helping your condition.

Visit your doctor regularly. Your doctor needs to check your progress and see whether you need to keep taking Provera.

Regularly check your breasts for any lumps and have regular professional breast examinations and mammograms, as recommended by your doctor.

If you use Provera as hormone replacement therapy (HRT) for 5 or more years, your doctor will need to physically check your pelvic organs and conduct blood tests, to rule out the risk of developing ovarian cancer.

The use of Provera may result in a decrease in the amount of calcium in your bones. This could increase your risk of developing brittle bones (osteoporosis), which can lead to bone breakages in later life. This effect can increase with long-term use of Provera. The amount of calcium in your bones will start to increase again once you stop treatment with Provera. The time to recovery depends on the duration of use. Some women may only partially recover the amount of calcium in their bone.

If you are taking Provera for prolonged periods, your doctor may also need to evaluate your bone mineral density (BMD).

Tell your doctor if, for any reason, you have not taken Provera exactly as prescribed.

Always discuss with your doctor any problems or difficulties during or after taking Provera.

Things you must not do

Do not change your dose or stop taking Provera without first checking with your doctor.

Do not take Provera to treat other complaints unless your doctor tells you to.

Do not give Provera to anyone else, even if they have the same condition as you.

Things to be careful of

Provera generally does not cause any problems with your ability to drive a car or operate machinery. However, Provera may cause dizziness, drowsiness or fatigue in some people. Make sure you know how you react to Provera before driving a car or operating machinery.

After taking Provera


Keep your tablets in the pack until it is time to take them. If you take the tablets out of the pack they may not keep well.

Keep Provera in a cool, dry place where the temperature stays below 30°C. Do not store Provera or any other medicine in a bathroom or near a sink. Do not leave it in the car or on windowsills. Heat and dampness can destroy some medicines.

Keep your Provera tablets where children cannot reach them. A locked cupboard at least one and a half metres above the ground is a good place to store medicines.


If your doctor tells you to stop taking Provera, or it has passed its expiry date, ask your pharmacist what to do with any tablets left over.

Schedule of Provera

Provera is an S4 (prescription only) medicine.

Side effects of Provera

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

If you are over 65 years of age you may have an increased chance of getting some side effects.

The use of an estrogen at the same time as Provera may also increase the risk of side effects.
