Precautions

US BOXED WARNING(S):
CARDIOVASCULAR DISORDERS, BREAST CANCER, ENDOMETRIAL CANCER, AND PROBABLE DEMENTIA
-Estrogens and progestins should not be used for the prevention of cardiovascular disease.
-The Women's Health Initiative (WHI) study reported increased risks of myocardial infarction, stroke, invasive breast cancer, pulmonary emboli, and deep vein thrombosis in postmenopausal women (50 to 79 years old) taking conjugated estrogens (CE) (0.625 mg) combined with medroxyprogesterone acetate (MPA) (2.5 mg) relative to placebo.
-The WHI Memory Study (WHIMS) study reported an increase of developing probable dementia in postmenopausal women 65 years and older treated with daily CE (0.625 mg) with MPA (2.5 mg) during 4 years compared to placebo; it is unknown if this applies to younger postmenopausal women.
-Lacking comparable data, assume the risk is similar for other doses and dosage forms of estrogens.

Recommendation:
-Estrogens, with or without progestins, should be prescribed at the lowest effective dose for the shortest duration consistent with treatment goals and risks.
