ESTROGENS INCREASE THE RISK OF ENDOMETRIAL CANCER
Close clinical surveillance of all women taking estrogens is
important. Adequate diagnostic
measures, including endometrial sampling when indicated, should be
undertaken to rule out
malignancy in all cases of undiagnosed persistent or recurring
abnormal vaginal bleeding. There
is no evidence that the use of "natural" estrogens results in a
different endometrial risk profile
than "synthetic" estrogens at equivalent estrogen doses. (See
_WARNINGS , MALIGNANT_
_NEOPLASMS , ENDOMETRIAL CANCER .)_
CARDIOVASCULAR AND OTHER RISKS
Estrogens with or without progestins should not be used for the
prevention of cardiovascular
disease. (See WARNINGS, CARDIOVASCULAR DISORDERS.)
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 of age) during 5 years of treatment with oral
conjugated estrogens (CE
0.625 mg) combined with medroxyprogesterone acetate (MPA 2.5 mg)
relative to placebo.
(See CLINICAL PHARMACOLOGY, CLINICAL STUDIES.)
The Women’s Health Initiative Memory Study (WHIMS), a substudy of
WHI, reported increased
risk of developing probable dementia in postmenopausal women 65 years
of age or older during 4
years of treatment with oral conjugated estrogens plus
medroxyprogesterone acetate relative to
placebo. It is unknown whether this finding applies to younger
postmenopausal women or to
women taking estrogen alone therapy. (See CLINICAL PHARMACOLOGY,
CLINICALSTUDIES.)
Other doses of oral conjugated estrogens with medroxyprogesterone
acetate, and other
combinations and dosage forms of estrogens and progestins were not
studied in the WHI clinical
trials and, in the absence of comparable data, these risks should be
assumed to be similar. Because
of these risks, estrogens with or without progestins should be
prescribed at t
