What is medroxyPROGESTERone?

Medroxyprogesterone is a progestin (a form of progesterone), a female hormone that helps regulate ovulation (the release of an egg from an ovary) and menstrual periods.

Medroxyprogesterone is used to treat conditions such as absent or irregular menstrual periods, or abnormal uterine bleeding. Medroxyprogesterone is also used to decrease the risk of endometrial hyperplasia (a condition that may lead to uterine cancer) while taking estrogens.

Medroxyprogesterone is also used to prevent overgrowth in the lining of the uterus in postmenopausal women who are receiving estrogen hormone replacement therapy.

Medroxyprogesterone may also be used for other purposes not listed in this medication guide.

Precautions

FDA pregnancy category X. Medroxyprogesterone can cause birth defects. Do not use if this medication you are pregnant. Tell your doctor right away if you become pregnant during treatment.

You should not use this medication if you are allergic to medroxyprogesterone, or if you have:

  • abnormal vaginal bleeding that has not been diagnosed;
  • a hormone-related cancer such as breast or uterine cancer;
  • liver disease; or
  • a history of stroke or blood clot.

If you have certain conditions, you may need a dose adjustment or special tests to safely take this medication. Before using medroxyprogesterone, tell your doctor if you have:

  • heart disease, congestive heart failure, recent stroke or heart attack
  • high blood pressure;
  • high cholesterol or triglycerides;
  • low levels of calcium in your blood;
  • severe pelvic pain;
  • recent miscarriage or abortion;
  • epilepsy;

Medroxyprogesterone can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

Medroxyprogesterone will not prevent heart disease, breast cancer, or dementia, and may actually increase the risk of developing these conditions in post-menopausal women. Medroxyprogesterone may also increase the risk of uterine or ovarian cancer in some women. Long-term treatment with estrogens and progestins (such as medroxyprogesterone) may also increase your risk of heart attack, blood clot, or stroke.

Talk to your doctor about your specific risks and benefits of taking this medication, especially if you smoke or are overweight. Your doctor should check your progress on a regular basis (every 3 to 6 months) to determine whether you should continue this treatment.

Avoid smoking while you are taking this medication. Smoking greatly increases your risk of blood clots.
