Precautions
US BOXED WARNING(S): CARDIOVASCULAR DISORDERS, BREAST CANCER, AND PROBABLE DEMENTIA
Estrogen plus progestin therapy:
- Estrogen plus progestin therapy should not be used for prevention of cardiovascular disease or dementia.
- Estrogen plus progestin increased risks of stroke, deep vein thrombosis (DVT), pulmonary embolism (PE), and myocardial infarction (MI) in postmenopausal women (50 to 79 years old) in the Women's Health Initiative (WHI) substudy.
- Estrogen plus progestin increased the risk of invasive breast cancer in the WHI substudy.
- Estrogen plus progestin therapy increased the risk of probable dementia in postmenopausal women 65 years and older in the WHI Memory Study (WHIMS) study.
- In the absence of comparable data, these risks should be assumed to be similar for other doses and combinations of estrogens and progestins.
- Prescribe at the lowest effective dose for the shortest duration consistent with treatment goals and individual risks.
Estrogen Only Therapy:
- There is an increased risk of endometrial cancer in women with uteruses using unopposed estrogens.
- Adding a progestin to estrogen therapy reduced the risk of endometrial hyperplasia, a possible precursor to endometrial cancer.
- The WHI estrogen alone substudy reported increased risk of stroke and deep vein thrombosis (DVT).
- The WHI Memory Study (WHIMS) reported an increased risk of probable dementia in postmenopausal women 65 years and older on estrogen-alone therapy.
- Estrogen alone therapy should not be used for prevention of cardiovascular disease or dementia.
