5 Warnings and Precautions
5.2 Malignant NeoplasmsAdditions and/or revisions underlined:
…
Breast Cancer
…
One large meta-analysis of prospective cohort studies reported increased risks that were dependent upon duration of use and could last up to > 10 years after discontinuation of estrogen plus progestin therapy and estrogen- alone therapy. Extension of WHI trials also demonstrated increased breast cancer risk associated with estrogen plus progestin therapy.

4 Contraindications
(Additions and/or revisions underlined)
ELESTRIN is contraindicated in women with any of the following conditions:
Undiagnosed abnormal genital bleeding [see Warnings and Precautions (5.2)].
Breast cancer or a history of breast cancer [see Warnings and precautions (5.2)].
Estrogen-dependent neoplasia [see Warnings and Precautions (5.2)].
Active DVT, PE, or history of these conditions [see Warnings and Precautions (5.1)].
Active arterial thromboembolic disease (for example, stroke and MI) or a history of these conditions [see warnings and Precautions (5.1)].
Known anaphylactic reaction, or angioedema, or hypersensitivity to ELESTRIN.
Hepatic impairment or disease.
Protein C, protein S, or antithrombin deficiency, or other known thrombophilic disorders.
5 Warnings and Precautions
5.1 Cardiovascular Disorders(Extensive changes; please refer to label)
(Additions and/or revisions underlined)
Estrogens may be poorly metabolized in women with hepatic impairment. Exercise caution in any woman with a history of cholestatic jaundice associated with past estrogen use or with pregnancy. In the case of recurrence of cholestatic jaundice, discontinued ELESTRIN.
(Additions and/or revisions underlined)
Estrogen administration leads to increased thyroid-binding globulin (TBG) levels. Women with normal thyroid function can compensate for the increased TBG by making more thyroid hormone, thus maintaining free T4 and T3 serum concentrations in the normal range. Women dependent on thyroid hormone replacement therapy who are also receiving estrogens may require increased doses of their thyroid replacement therapy. Monitor thyroid function in these women during treatment with ELESTRIN to maintain their free thyroid hormone levels in an acceptable range.
(Additions and/or revisions underlined)
Estrogens may cause some degree of fluid retention. Monitor any woman with a condition(s) that might predispose her to fluid retention, such as cardiac or renal impairment. Discontinue estrogen-alone therapy, including ELESTRIN, with evidence of medically concerning fluid retention.
(Additions and/or revisions underlined)
Estrogen-induced hypocalcemia may occur in women with hypoparathyroidism. Consider whether the benefits of estrogen therapy, including ELESTRIN, outweigh the risks in such women.
(Additions and/or revisions underlined)
A few cases of malignant transformation of residual endometrial implants have been reported in women treated post-hysterectomy with estrogen-alone therapy. Consider the addition of a progestin for women known to have residual endometriosis post-hysterectomy.
(Additions and/or revisions underlined)
Exogenous estrogens may exacerbate symptoms of angioedema in women with hereditary angioedema. Consider whether the benefits of estrogen therapy outweigh the risks in such women.
(Additions and/or revisions underlined)
Estrogen therapy, including ELESTRIN, may cause an exacerbation of asthma, diabetes mellitus, epilepsy, migraine, porphyria, systemic lupus erythematosus, and hepatic hemangiomas.
Consider whether the benefits of estrogen therapy outweigh the risks in such women.
(Additions and/or revisions underlined)
Estradiol absorption was increased when sunscreen was applied 10 minutes before ELESTRIN application. Do not apply sunscreen to the application site of ELESTRIN until at least 25 minutes after the application of ELESTRIN.
(Additions and/or revisions underlined)
Endometrial Cancer
Clinical surveillance of all women using estrogen-alone or estrogen/progestin combinations is important. Perform adequate diagnostic measures, including directed or random endometrial sampling when indicated, to rule out malignancy in postmenopausal women with persistent or recurring abnormal vaginal bleeding with unknown etiology.
There is no evidence that the use of natural estrogens results in a different endometrial risk profile than synthetic estrogens of equivalent estrogen dose. Adding a progestin to estrogen therapy has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer.
In a 12-week clinical trial, one case of complex hyperplasia with atypia was reported in the ELESTRIN 1.7 g per day dose.
Breast Cancer
The WHI substudy of daily CE (0.625 mg)-alone provided information about breast cancer in estrogen-alone users. In the WHI estrogen-alone substudy, after an average of follow-up of 7.1 years, daily CE-alone was not associated with an increased risk of invasive breast cancer [relative risk (RR) 0.80] compared to placebo [see Clinical Studies (14.2)].
After a mean follow-up of 5.6 years, the WHI substudy of daily CE (0.625 mg) plus MPA (2.5 mg) reported an increased risk of invasive breast cancer in women who took daily CE plus MPA compared to placebo.
Consistent with the WHI clinical trial, observational studies have also reported an increased risk of breast cancer with estrogen plus progestin therapy, and a smaller increase in the risk for breast cancer with estrogen-alone therapy, after several years of use.
Ovarian Cancer
The CE plus MPA substudy of WHI reported that estrogen plus progestin increased the risk of ovarian cancer. After an average follow-up of 5.6 years, the relative risk for ovarian cancer for CE plus MPA versus placebo was 1.58 [95 percent CI, 0.77-3.24] but it was not statistically significant. The absolute risk for CE plus MPA versus placebo was 4 versus 3 cases per 10,000 women-years.
(Additions and/or revisions underlined)
In the WHI Memory Study (WHIMS) estrogen-alone ancillary study, a population of 2,947 hysterectomized women 65 to 79 years of age was randomized to daily CE (0.625 mg)-alone or placebo.
(Additions and/or revisions underlined)
Estrogen administration may lead to severe hypercalcemia in women with breast cancer and bone metastases. Discontinue estrogens, including ELESTRIN if hypercalcemia occurs, and take appropriate measures to reduce the serum calcium level.
(Additions and/or revisions underlined)
Retinal vascular thrombosis has been reported in women receiving estrogens. Discontinue ELESTRIN pending examination if there is sudden partial or complete loss of vision, or a sudden onset of proptosis, diplopia, or migraine. Discontinue estrogens, including ELESTRIN, if examination reveals papilledema or retinal vascular lesions(Additions and/or revisions underlined)
In women with pre-existing hypertriglyceridemia, estrogen therapy may be associated with elevations of plasma triglycerides leading to pancreatitis. Consider discontinuation of ELESTRIN if pancreatitis occurs.
8 Use in Specific Populations
8.1 Pregnancy
(Pregnancy and Lactation Labeling Rule (PLLR) conversion; additions and/or revisions underlined)
Risk Summary
ELESTRIN is not indicated for use in pregnancy. There are no data with the use of ELESTRIN in pregnant women; however, epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies or limb-reduction defects) following exposure to combined hormonal contraceptives (estrogen and progestins) before conception or during early pregnancy. Animal studies to evaluate embryo/fetal toxicity were not conducted with ELESTRIN.
8.2 Lactation
(Pregnancy and Lactation Labeling Rule (PLLR) conversion; additions and/or revisions underlined)
Risk Summary
Estrogens are present in human milk and can reduce milk production in breast-feeding women. This reduction can occur at any time but is less likely to occur once breast-feeding is well- established. The developmental and health benefits of breast-feeding should be considered along with the mother’s clinical need for ELESTRIN and any potential adverse effects on the breast- fed child from ELESTRIN or from the underlying maternal condition.
8.4 Pediatric Use
(Additions and/or revisions underlined)
ELESTRIN is not indicated in pediatric patients. Clinical studies have not been conducted in the pediatric population.

(Additions and/or revisions underlined)
Estrogen-induced hypocalcemia may occur in women with hypoparathyroidism. Consider whether the benefits of estrogen therapy, including ELESTRIN, outweigh the risks in such women.
5.14 Exacerbation of Endometriosis
(Additions and/or revisions underlined)
A few cases of malignant transformation of residual endometrial implants have been reported in women treated post-hysterectomy with estrogen-alone therapy. Consider the addition of a progestin for women known to have residual endometriosis post-hysterectomy.
5.15 Hereditary Angioedema
(Additions and/or revisions underlined)
Exogenous estrogens may exacerbate symptoms of angioedema in women with hereditary angioedema. Consider whether the benefits of estrogen therapy outweigh the risks in such women.
5.16 Exacerbation of Other Conditions
(Additions and/or revisions underlined)
Estrogen therapy, including ELESTRIN, may cause an exacerbation of asthma, diabetes mellitus, epilepsy, migraine, porphyria, systemic lupus erythematosus, and hepatic hemangiomas.
Consider whether the benefits of estrogen therapy outweigh the risks in such women.
(Additions and/or revisions underlined)
Estradiol absorption was increased when sunscreen was applied 10 minutes before ELESTRIN application. Do not apply sunscreen to the application site of ELESTRIN until at least 25 minutes after the application of ELESTRIN.
5.19 Miscellaneous
(Additions and/or revisions underlined)
Alcohol based gels, including ELESTRIN, are potentially flammable. Avoid fire, flame, or smoking until ELESTRIN has dried.
5.3 Probable Dementia
(Additions and/or revisions underlined)
In the WHI Memory Study (WHIMS) estrogen-alone ancillary study, a population of 2,947 hysterectomized women 65 to 79 years of age was randomized to daily CE (0.625 mg)-alone or placebo.

5 Warnings and Precautions
5.2 Malignant NeoplasmsOvarian Cancer
Additions and/or revisions underlined:
… A meta-analysis of 17 prospective and 35 retrospective epidemiology studies found that women who used hormonal therapy for menopausal symptoms had an increased risk for ovarian cancer. The primary analysis, using case-control comparisons, included 12,110 cancer cases from the 17 prospective studies. The relative risks associated with current use of hormonal therapy was 1.41 (95% confidence interval [CI] 1.32 to 1.50); there was no difference in the risk estimates by duration of the exposure (less than 5 years [median of 3 years] vs. greater than 5 years [median of 10 years] of use before the cancer diagnosis). The relative risk associated with combined current and recent use (discontinued use within 5 years before cancer diagnosis) was 1.37 (95% CI 1.27-1.48), and the elevated risk was significant for both estrogen-alone and estrogen plus progestin products. The exact duration of hormone therapy use associated with an increased risk of ovarian cancer, however, is unknown.
