Transdermal route (patch, extended release)

Cardiovascular Disorders, Probable Dementia, Breast Cancer, and Endometrial Cancer. Estrogen Plus Progestin Therapy. Cardiovascular Disorders and Probable Dementia. Estrogens plus progestogen therapy should not be used for the prevention of cardiovascular disease or dementia.The Women's Health Initiative (WHI) estrogen plus progestin substudy reported an increased risk of deep vein thrombosis (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 conjugated estrogens (CE) [0.625 mg] combined with medroxyprogesterone acetate (MPA) [2.5 mg], relative to placebo.The WHI Memory Study (WHIMS) estrogen plus progestin ancillary study of 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.Breast Cancer. The WHI estrogen plus progestin substudy demonstrated an increased risk of invasive breast cancer.Only daily oral 0.625 mg CE and 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.Prescribe estrogens with or without progestogens at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.Estrogen-Alone Therapy. Endometrial Cancer. There is an increased risk of endometrial cancer in a woman with a uterus who uses unopposed estrogens.

Adding a progestogen 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 rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding.Cardiovascular Disorders and Probable Dementia. The WHI estrogen-alone substudy reported increased risks of stroke and DVT in postmenopausal women (50 to 79 years of age) during 7.1 years of treatment with daily oral CE (0.625 mg)-alone, relative to placebo.The 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.Do not use estrogen-alone therapy for the prevention of cardiovascular disease or dementia.Only daily oral 0.625 mg CE was studied in the estrogen-alone substudy of the WHI.

Therefore, the 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.Prescribe estrogens with or without progestogens at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.

General

The most common adverse events were application site reactions, which usually disappeared 2 to 3 days after patch removal.^[Ref]

Cardiovascular

Estrogen plus Progestin:

• Frequency not reported: Cardiovascular disorders

Estradiol / levonorgestrel

• Common (1% to 10%): Hypertension^[Ref]

Cardiovascular disorders described as an increase risk of PE, DVT, stroke, and MI have been reported in the WHI (Women's Health Initiative) estrogen plus progestin substudy. Postmenopausal women 50 to 79 years of age receiving oral conjugated estrogens (0.625 mg) combined with medroxyprogesterone (2.5 mg) showed an increased risk of stroke compared to placebo (33 versus 25 per 10,000 women-years); coronary heart disease defined as nonfatal MI, silent MI or coronary heart disease death (41 versus 34 per 10,000 women-years); venous thromboembolism (35 versus 17 per 10,000 women-years).^[Ref]

Oncologic

Estrogen plus Progestin:

• Frequency not reported: Malignant neoplasms^[Ref]

The Women's Health Initiative (WHI) has shown, after a mean follow-up of 5.6 years, estrogen (0.625 mg) plus progestin (2.5 mg) use increased risk of invasive breast cancer. The relative risk (RR) of invasive breast cancer was reported at 1.24 (absolute risk 41 versus 33 cases per 10,000 women-years) compared with placebo. For women with a prior history of hormone therapy, RR was 1.86 (absolute risk 46 versus 25 cases per 10,000 women-years) compared with placebo. In the same substudy, invasive breast cancers were larger, more likely to be node positive, and diagnosed at a more advanced stage.

Endometrial Cancer has been reported with the use of unopposed estrogen therapy in woman with a uterus; risk is about 2 to 12 times greater without progestin. Most studies show the greatest risk appears associated with prolonged use. Risk has been shown to persist for 8 to 15 years after estrogen therapy is discontinued. Adding a progestin to estrogen therapy in postmenopausal women has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer

A meta-analysis of 17 prospective and 35 retrospective epidemiology studies found that women using hormonal therapy for menopausal symptoms had an increased risk for ovarian cancer. Relative risks associated with current use was calculated at 1.41 (95% confidence interval [CI] 1.32 to 1.50). The relative risk associated with combined current and recent use (discontinued use within 5 years) were comparable and elevated risk was significant for both estrogen-alone and estrogen plus progestin products. It is not possible to determine the exact duration of hormone use associated with an increased risk of ovarian cancer.^[Ref]
