Consumer Information

Information about the product including what the product is used for, dosage, warnings, proper use and side effects. This summary will not tell you everything about the product. Contact your healthcare professional if you have any questions about the product.


What the medication is used for
  • Hormonal Replacement Therapy for Menopause –
    TEVA-MEDROXYPROGESTERONE is used for women with intact uteri who are also receiving estrogen therapy.
  • To Treat Menstrual Disorders due to Hormonal Imbalance -
    In non-pregnant women, TEVA-MEDROXYPROGESTERONE helps to balance the effect of estrogen.
  • To Treat Cancer:
    - To treat and relieve symptoms associated with endometrial cancer.
    - To treat and relieve symptoms of breast cancer in postmenopausal women.

TEVA-MEDROXYPROGESTERONE should be used only under the supervision of a doctor, with regular follow-up at least once a year to identify the side effects associated with its use. Your first follow-up visit should be within 3 to 6 months of starting treatment. Your visit may include a blood pressure check, a breast exam, a Pap smear and pelvic exam. You should have a mammogram before starting treatment and at regular intervals as recommended by your doctor. Your doctor may recommend some blood tests.

Progestin, when used with estrogen therapy, have important benefits but also some risks. You should carefully discuss the risks and benefits of hormone replacement therapy (HRT) with your doctor. If you use progestin with estrogen therapy, check with your doctor to be sure you are using the lowest possible dose that works, and that you don’t use them longer than necessary. How long you need to use HRT will depend on the reason for use. You should regularly talk with your doctor about whether you still need treatment with HRT.

If you have any questions about this medication or your condition, please ask your doctor or pharmacist.

What it does

TEVA-MEDROXYPROGESTERONE (medroxyprogesterone acetate) is a hormone replacement therapy (HRT) that contains a manufactured progesterone hormone, progestin, that is similar to the progesterone produced by a woman’s ovaries. When given with an appropriate dose of estrogen hormone, TEVA-MEDROXYPROGESTERONE significantly reduces the risk of developing endometrial hyperplasia (overgrowth of the uterus lining) and the risk of cancer of the uterus. Seven (7) days after stopping TEVA-MEDROXYPROGESTERONE treatment, you should have withdrawal bleeding. If bleeding occurs during the TEVA-MEDROXYPROGESTERONE treatment, talk to your doctor, as the dose may need to be modified.

Progesterone therapy regulates bleeding patterns. When given to non-pregnant women to treat menstrual disorders, the endometrium (inner lining of the uterus) does not grow as much and bleeding decreases. This is because TEVA-MEDROXYPROGESTERONE helps to balance the effect of estrogen. You will know that TEVA-MEDROXYPROGESTERONE is effective if it induces a period (any bleeding more than light spotting) within 2 weeks after TEVA-MEDROXYPROGESTERONE is given. This bleeding will usually occur 2-7 days after the TEVA-MEDROXYPROGESTERONE is finished.

For Oncology:
When used to treat cancer, TEVA-MEDROXYPROGESTERONE is thought to work two-ways: it decreases hormone release and it prevents the cancer cells from multiplying by balancing out high levels of estrogen. The response to hormonal therapy for endometrial or breast cancer may not be evident until 8 to 10 weeks of therapy.

When it should not be used

You should not take TEVA-MEDROXYPROGESTERONE if you have any of the following conditions:

  • In the presence of liver disease;
  • If you have had or have cancer of the breast or uterus, unless TEVA-MEDROXYPROGESTERONE is being used to treat and relieve the symptoms associated with these cancers;
  • If you have abnormal vaginal bleeding;
  • If you are pregnant;
  • If you have had or have any blood circulation problems, such as blood clots, stroke, blindness or migraine headaches;
  • If you have had a stroke or heart attack;
  • If you have had an unusual allergic response to progestin or to any of the ingredients in the tablet.

Do not take TEVA-MEDROXYPROGESTERONE for conditions for which it was not prescribed. Do not give TEVA-MEDROXYPROGESTERONE to other people, even if they have the same symptoms you have. It may harm them.

Warnings and precautions

Serious Warnings and Precautions

The Women’s Health Initiative (WHI) trial is a large clinical study that assessed the benefits and risks of oral combined estrogen plus progestin therapy and oral estrogen-alone therapy compared with placebo (a pill with no active ingredients) in postmenopausal women.

The WHI trial indicated an increased risk of myocardial infarction (heart attack), stroke, breast cancer, pulmonary emboli (blood clots in the lungs) and deep vein thrombosis (blood clots in the large veins) in postmenopausal women taking oral combined estrogen plus progestin.

The WHI trial indicated an increased risk of stroke and deep vein thrombosis in postmenopausal women with prior hysterectomy (surgical removal of the uterus) taking oral estrogen-alone.

Therefore, you should highly consider the following:

  • There is an increased risk of developing invasive breast cancer, heart attack, stroke and blood clots in both lungs and large veins with the use of estrogen plus progestin therapy.
  • There is an increased risk of stroke and blood clots in the large veins with the use of estrogen-alone therapy.
  • Estrogens with or without progestins should not be used for the prevention of heart disease or stroke.
  • Estrogens with or without progestins should be used at the lowest effective dose and for the shortest period of time possible. Regular medical followup is advised.

Breast Cancer

The results of the WHI trial indicated an increased risk of breast cancer in post-menopausal women taking combined estrogen plus progestin compared to women taking placebo. The results of the WHI trial indicated no difference in the risk of breast cancer in postmenopausal women with prior hysterectomy taking estrogen-alone compared to women taking placebo.

Estrogens with or without progestins should not be taken by women who have a personal history of breast cancer.

In addition, women with a family history of breast cancer or women with a history of breast lumps, breast biopsies or abnormal mammograms (breast x-rays) should consult with their doctor before starting HRT.

Women should have a mammogram before starting HRT and at regular intervals during treatment as recommended by their doctor. Regular breast examinations by a doctor and regular breast self-examinations are recommended for all women. You should review technique for breast self-examination with your doctor.

Overgrowth of the lining of the uterus and cancer of the uterus

The use of estrogen-alone therapy by post menopausal women who still have a uterus increases the risk of developing endometrial hyperplasia (overgrowth of the lining of the uterus), which increases the risk of endometrial cancer (cancer of the lining of the uterus).

The purpose of adding a progestin medication to estrogen therapy is to reduce the risk of endometrial hyperplasia.

You should discuss progestin therapy and risk factors for endometrial hyperplasia and endometrial carcinoma with your doctor. You should also report any unexpected or unusual vaginal bleeding to your doctor.

If you have had your uterus removed, you are not at risk of developing endometrial hyperplasia or endometrial carcinoma. Progestin therapy is therefore not generally required in women who have had a hysterectomy.

Ovarian Cancer

In some studies, the use of estrogen-alone and estrogen plus progestin therapies for 5 or more years has been associated with an increased risk of ovarian cancer.

Heart Disease and Stroke

The results of the WHI trial indicated an increased risk of stroke and coronary heart disease in post-menopausal women taking combined estrogen plus progestin compared to women taking placebo.

The results of the WHI trial indicated an increased risk of stroke, but no difference in the risk of coronary heart disease in post-menopausal women with prior hysterectomy taking estrogen alone compared to women taking placebo.

Abnormal Blood Clotting

The results of the WHI trial indicated an increased risk of blood clots in the lungs and large veins in post-menopausal women taking combined estrogen plus progestin compared to women taking placebo.

The results of the WHI trial indicated an increased risk of blood clots in the large veins, but no difference in the risk of blood clots in the lungs in post-menopausal women with prior hysterectomy taking estrogen-alone compared to women taking placebo.
The risk of blood clots also increases with age, if you or a family member has had blood clots, if you smoke or if you are severely overweight. The risk of blood clots is also temporarily increased if you are immobilized for long periods of time and following major surgery. You should discuss risk factors for blood clots with your doctor since blood clots can be life threatening or cause serious disability.

Gallbladder Disease

The use of estrogens by postmenopausal women has been associated with an increased risk of gallbladder disease requiring surgery.

Dementia The Women’s Health Initiative Memory Study (WHIMS) was a substudy of the WHI trial and indicated an increased risk of dementia (loss of memory and intellectual function) in postmenopausal women age 65 and over taking oral combined estrogen plus progestin compared to women taking placebo.

The WHIMS indicated no difference in the risk of dementia in postmenopausal women age 65 and over with prior hysterectomy taking oral estrogen-alone compared to women taking placebo.
