O que dizem as bulas da FDA
Da bula de Estrogênios conjugados (Premarin) · em vigor desde 2025-05-30
Adding a progestin to estrogen therapy has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer.
Estrogens with or without progestins should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.
Estrogen Plus Progestin Therapy Cardiovascular Disorders and Probable Dementia Estrogen plus progestin therapy should not be used for the prevention of cardiovascular disease or dementia.
(See CLINICAL STUDIES and WARNINGS, Cardiovascular disorders and Probable Dementia .) The WHI estrogen plus progestin substudy reported increased risks of DVT, pulmonary embolism (PE), stroke and myocardial infarction (MI) in postmenopausal women (50 to 79 years of age) during 5.6 years of treatment with daily oral CE (0.625 mg) combined with medroxyprogesterone…
(See CLINICAL STUDIES and WARNINGS, Cardiovascular disorders .) The WHIMS estrogen plus progestin ancillary study of the WHI reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 4 years of treatment with daily CE (0.625 mg) combined with MPA (2.5 mg), relative to placebo.

Coronary Heart Disease In women 50 to 59 years of age, the WHI estrogen plus progestin trial reported a relative risk for coronary heart disease (CHD) events (defined as nonfatal MI, silent MI, or CHD death) of 1.34 (95% CI, 0.82, 2.19) for CE/MPA compared placebo, with a risk difference of 5 per 10,000 WYs (23 versus 17).
Breast Cancer Progesterone is contraindicated in women with breast cancer, a history of breast cancer, or estrogen-dependent neoplasia (see CONTRAINDICATIONS).
The Women’s Health Initiative Study In the Women’s Health Initiative (WHI) estrogen plus progestin substudy (daily CE [0.625 mg] plus MPA [2.5 mg] versus placebo), there was a higher relative risk of nonfatal stroke and invasive breast cancer in women greater than 65 years of age (see CLINICAL STUDIES and WARNINGS, Cardiovascular disorders and Malignant neoplasms…
The Women’s Health Initiative (WHI) estrogen plus progestin trial reported increased risks of PE, DVT, stroke, and MI in postmenopausal women (50 to 79 years of age, average age 63.4 years) during 5.6 years of treatment with daily oral conjugated estrogens (CE) [0.625 mg] combined with medroxyprogesterone acetate (MPA) [2.5 mg], relative to placebo.
Therefore, the relevance of the WHI findings regarding adverse cardiovascular events to lower CE plus other MPA doses, other routes of administration, or other estrogen plus progestogen products is not known.
