Regimen 1 (Cyclic Combined Estrogen-Progestin Therapy): Conjugated estrogens 0.625 mg orally once a day AND Medroxyprogesterone acetate 5 mg orally once a day for 14 days per month.

-or-

Regimen 2 (Continuous Combined Estrogen-Progestin Therapy): Conjugated estrogens 0.3 mg orally once a day AND Medroxyprogesterone acetate 1.5 mg orally once a day or conjugated estrogens 0.625 mg orally once a day AND Medroxyprogesterone acetate 2.5 mg or 5 mg orally once a day.

Long-term therapy (for more than 5 years) is generally necessary in order to obtain substantive benefits in reducing the risk of bone fracture. Maximal benefits are obtained if estrogen therapy is initiated as soon after menopause as possible. The optimal duration of therapy has not been definitively determined.

In addition to hormonal therapy, adequate calcium intake is important for postmenopausal women who require treatment or prevention of osteoporosis. The average diet of older American women contains 400 to 600 mg of calcium per day. 1500 mg per day has been suggested as optimal intake. If dietary intake is insufficient to achieve 1500 mg per day, dietary supplementation may be useful in women who have no contraindication to calcium supplementation.

Usual Adult Dose for Postmenopausal Symptoms

Renal Dose Adjustments

Data not available

Liver Dose Adjustments

The hepatic metabolism of conjugated estrogens may be impaired in patients with liver disease and caution is recommended if patients with liver disease must receive conjugated estrogen therapy. The use of medroxyprogesterone is considered to be contraindicated for use in patients with liver disease.

Precautions

Regimen 1 and Regimen 2 (the combined regimens) are contraindicated in patients with established hyperlipidemia or ischemic heart disease.

Combined hormone replacement therapy should not be initiated or continued in women for prevention of coronary heart disease because the health risks may exceed the benefits. The Women's Health Initiative (WHI) study was terminated early because a significantly higher risk of invasive breast cancer, stroke and myocardial infarction was associated with long-term use of conjugated estrogens/medroxyprogesterone. In addition, the results of the Heart and Estrogen/progestin Replacement Study Follow-up (HERS II) have indicated that long-term use increases the risk of thromboembolism, heart attacks, and biliary surgery.
