Estrogen Alone TherapyEndometrial Cancer - There is an increased risk of cancer in a woman with a uterus who uses unopposed estrogens. Adding a progestin to estrogen therapy has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer. Perform adequate diagnostic measures, including directed or random endometrial sampling when indicated, to rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding.Cardiovascular Disorders and Probable Dementia - The Women's Health Initiative (WHI) estrogen-alone substudy reported increased risks of stroke and deep vein thrombosis (DVT) in postmenopausal women (50 to 79 years of age) during 7.1 years of treatment with daily oral conjugated estrogens (CE) [0.625 mg]-alone, relative to placebo.Cardiovascular Disorders and Probable Dementia - The WHI Memory Study (WHIMS) estrogen-alone ancillary study of WHI reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 5.2 years of treatment with daily CE (0.625 mg)-alone, relative to placebo. It is unknown whether this finding applies to younger postmenopausal women.Cardiovascular Disorders and Probable Dementia - Do not use estrogen and progestin therapy for the prevention of cardiovascular disease or dementia.Cardiovascular Disorders and Probable Dementia - Only daily oral 0.625 mg CE was studied in the estrogen -alone substudy of the WHI. Therefore, thee relevance of the WHI findings regarding adverse cardiovascular events and dementia to lower CE doses, other routes of administration, or other estrogen-alone products is not known. Without such data, it is not possible to definitively exclude these risks or determine the extent of these risks for other products. Discuss with your patient the benefits and risks of estrogen-alone therapy, taking into account her individual risk profile.Cardiovascular Disorders and Probable Dementia - In the absence of comparable data, these risks should be assumed to be similar for other doses of CE and other dosage forms of estrogens.Cardiovascular Disorders and Probable Dementia - Prescribe estrogens with or without progestins at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.Estrogen Plus Progestin TherapyCardiovascular 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 combined medroxyprogesterone acetate (MPA) [2.5 mg], relative to placebo.Cardiovascular Disorders and Probable Dementia - 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. It is unknown whether this finding applies to younger postmenopausal women.Cardiovascular Disorders and Probable Dementia - Do not use estrogen and progestin therapy for the prevention of cardiovascular disease or dementia.Breast Cancer - The WHI estrogen plus progestin substudy also demonstrated an increased risk of invasive breast cancer.Breast Cancer - Only daily oral 0.625 mg CE and 2.5 mg MPA were studied in the estrogen plus progestin substudy of the WHI. Therefore, the relevance of the WHI findings regarding adverse cardiovascular events, dementia, and breast cancer to lower CE plus other MPA doses, other routes of administration, or other estrogen plus progestogen products is not known. Without such data, it is not possible to definitively exclude these risks or determine the extent of these risks for other products. Discuss with your patient the benefits and risks of estrogen plus progestogen therapy, taking into account her individual risk profile.Breast Cancer - Prescribe estrogens with or without progestins at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.
Vaginal route (Insert, Extended Release)
Use of unopposed estrogens increases the risk of endometrial cancer, while addition of a progestin decreases the risk of endometrial hyperplasia. Rule out malignancy if abnormal vaginal bleeding develops. Do not use estrogen alone or in combination with progestin to prevent cardiovascular disease or dementia. There is an increased risk of cardiovascular disorders (ie, DVT, pulmonary embolism, stroke, myocardial infarction) with combination therapy in women 50 years or older, and an increased risk of dementia in women 65 years or older with estrogen monotherapy or combination therapy. Combination therapy also increases the risk of invasive breast cancer. Prescribe estrogens with or without progestins at the lowest effective dose and for the shortest duration consistent with risks and treatment goals.
