Estrogens increase the risk of endometrial cancer in postmenopausal women. (See Endometrial Cancer under Cautions.)
Do not use estrogens with or without progestins for prevention of cardiovascular disease (see Cardiovascular Risk Reduction under Uses and Cardiovascular Disorders under Cautions) or dementia (see Alzheimer’s Disease under Uses).
The Women’s Health Initiative (WHI) study of estrogen alone reported increased risks of stroke and DVT in postmenopausal women receiving approximately 7 years of therapy with conjugated estrogens 0.625 mg daily.
The WHI study of estrogen plus progestin reported increased risks of MI, stroke, invasive breast cancer, pulmonary embolism, and DVT in postmenopausal women receiving ≥5 years of therapy with conjugated estrogens 0.625 mg in conjunction with medroxyprogesterone acetate 2.5 mg daily.
The WHI Memory Study (WHIMS) reported increased risk of developing probable dementia in postmenopausal women ≥65 years of age receiving long-term therapy (4–5 years) with conjugated estrogens in conjunction with medroxyprogesterone acetate or conjugated estrogens alone. Not known whether this finding also applies to younger postmenopausal women.
Other dosages of conjugated estrogens with medroxyprogesterone and other combinations or dosage forms of estrogens with progestin not studied in WHI trials; in the absence of comparable data, assume risks are similar.
Prescribe estrogens (with or without progestins) at the lowest effective dose and for the shortest duration consistent with treatment goals and risks for the individual woman.

This medicine can increase the risk of developing a condition (endometrial hyperplasia) that may lead to cancer of the lining of the uterus. Taking progestins, another hormone drug, with this medicine lowers the risk of developing this condition. Therefore, if your uterus has not been removed (by a hysterectomy), your doctor may prescribe a progestin for you to take together with your estrogen. You should know, however, that taking estrogens with progestins may have additional health risks. You should discuss the use of estrogens and progestins with your health care professional to determine the benefits and risks for you.
