🩺What it's for
The Estradiol Transdermal System is indicated for:
💊How to take it
Generally, when estrogen is prescribed for a postmenopausal woman with a uterus, consider addition of a progestogen to reduce the risk of endometrial cancer. Generally, a woman without a uterus does not need to use a progestogen in addition to her estrogen therapy. In some cases, however, hysterectomized women who have a history of endometriosis may need a progestogen [see Warnings and Precautions (5.2, 5.14)].
ℹ️Common side effects
The following serious adverse reactions are discussed elsewhere in the labeling: Cardiovascular Disorders [see Boxed Warning, and Warnings and Precautions (5.1)] Malignant Neoplasms [see Boxed Warning, and Warnings and Precautions (5.2)] The most common adverse reactions ( 10 percent) with the Estradiol Transdermal System are: breast pain, upper respiratory tract infections, headaches, abdominal pain, pain, and edema.
⚠️Serious risks
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.
📋Interactions & cautions
Accelerated prothrombin time, partial thromboplastin time, and platelet aggregation time; increased platelet count; increased factors II, VII antigen, VIII antigen, VIII coagulant activity, IX, X, XII, VII-X complex, II-VII-X complex, and beta-thromboglobulin; decreased levels of antifactor Xa and antithrombin III, decreased antithrombin III activity; increased levels of fibrinogen and fibrinogen activity; increased plasminogen antigen and activity.
📦Storage & missed dose
Store at 20 C to 25 C (66 F to 77 F); excursions permitted between 15 C and 30 C (59 F and 86 F). Do not store above 86 F (30 C). Do not store unpouched. Apply immediately upon removal from the protective pouch. Used transdermal systems still contain active hormone. To discard, fold the sticky side of the transdermal system together, place it in a sturdy child-proof container, and place this container in the trash. Used transdermal systems should not be flushed in the toilet.

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 to rule out malignancy in postmenopausal women with undiagnosed, persistent or recurring abnormal genital bleeding [see Warnings and Precautions (5.2)]. 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 [see Warnings and Precautions (5.1), and Clinical Studies (14.3)]. The WHI Memory Study (WHIMS) estrogen-alone ancillary study of the WHI reported an increased risk of developing probable dementia in postmenopausal women 65 years of age and 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 [see Warnings and Precautions (5.3), Use in Specific Populations (8.5), and Clinical Studies (14.4)]. Do not use estrogen-alone therapy for the prevention of cardiovascular disease or dementia [see Warnings and Precautions (5.1, 5.3), and Clinical Studies (14.3, 14.4)]. 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. Estrogen Plus Progestin Therapy 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 acetate (MPA) [2.5 mg], relative to placebo [see Warnings and Precautions (5.1), and Clinical Studies (14.3)]. 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 and 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 [see Warnings and Precautions (5.3), Use in Specific Populations (8.5), and Clinical Studies (14.4)]. Do not use estrogen plus progestogen therapy for the prevention of cardiovascular disease or dementia [see Warnings and Precautions (5.1, 5.3), and Clinical Studies (14.3, 14.4)]. Breast Cancer The WHI estrogen plus progestin substudy also demonstrated an increased risk of invasive breast cancer [see Warnings and Precautions (5.2), and Clinical Studies (14.3)]. 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. 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.

The WHI estrogen plus progestin substudy was stopped early. According to the predefined stopping rule, after an average follow-up of 5.6 years of treatment, the increased risk of invasive breast cancer and cardiovascular events exceeded the specified benefits included in the "global index". The absolute excess risk of events included in the global index was 19 per 10,000 women-years. For those outcomes included in the WHI global index that reached statistical significance after 5.6 years of follow-up, the absolute excess risks per 10,000 women-years in the group treated with CE plus MPA were 7 more CHD events, 8 more strokes, 10 more PEs, and 8 more invasive breast cancers, while the absolute risk reduction per 10,000 women-years were 6 fewer colorectal cancers and 5 fewer hip fractures. Results of the CE plus MPA substudy, which included 16,608 women (average 63 years of age, range 50 to 79; 83.9 percent White, 6.5 percent Black, 5.4 percent Hispanic, 3.9 percent Other), are presented in Table 5 . These results reflect centrally adjudicated data after an average follow-up of 5.6 years.

Generally, when estrogen is prescribed for a postmenopausal woman with a uterus, consider addition of a progestogen to reduce the risk of endometrial cancer. Generally, a woman without a uterus does not need to use a progestogen in addition to her estrogen therapy. In some cases, however, hysterectomized women who have a history of endometriosis may need a progestogen [see Warnings and Precautions (5.2, 5.14)]. Use estrogen-alone, or in combination with a progestogen at the lowest effective dose and for the shortest duration consistent with treatment goals and risks for the individual woman. Reevaluate postmenopausal women periodically as clinically appropriate to determine if treatment is still necessary. Start therapy with the Estradiol Transdermal System 0.025 mg per day applied to the skin once-weekly. Dosage adjustment should be guided by the clinical response (2.1) Place the Estradiol Transdermal System on a clean, dry area of the lower abdomen (below the umbilicus) or upper quadrant of the buttock. Do not apply the Estradiol Transdermal System to the breasts (2.5)
Start therapy with Estradiol Transdermal System 0.025 mg per day applied to the skin once weekly. Make dosage adjustments based on the clinical response. Attempt to taper or discontinue Estradiol Transdermal System at 3 to 6 month intervals.

Start therapy with Estradiol Transdermal System 0.025 mg per day applied to the skin once weekly.
Remove Estradiol Transdermal System carefully and slowly to avoid irritation of the skin. If any adhesive remains on the skin after removal of Estradiol Transdermal System, allow the area to dry for 15 minutes and then gently rub the area with an oil-based cream or lotion to remove the adhesive residue. Used patches still contain some active hormones. Carefully fold each patch in half so that it sticks to itself before throwing it away.
Estradiol Transdermal System, 0.025 mg per day each 6.5 cm2 system contains 2 mg of estradiol Estradiol Transdermal System, 0.0375 mg per day each 9.375 cm2 system contains 2.85 mg of estradiol Estradiol Transdermal System, 0.05 mg per day each 12.5 cm2 system contains 3.8 mg of estradiol Estradiol Transdermal System, 0.060 mg per day each 15 cm2 system contains 4.55 mg of estradiol Estradiol Transdermal System, 0.075 mg per day each 18.75 cm2 system contains 5.7 mg of estradiol Estradiol Transdermal System, 0.1 mg per day each 25.0 cm2 system contains 7.6 mg of estradiol Transdermal system 0.025 mg per day, 0.0375 mg per day, 0.05 mg per day, 0.06 mg per day, 0.075 mg per day and 0.1 mg per day (3)
Estradiol Transdermal System is contraindicated in women with any of the following conditions: Undiagnosed abnormal genital bleeding [see Warnings and Precautions (5.2)] Breast cancer or history of breast cancer [see Warnings and Precautions (5.2)] Estrogen-dependent neoplasia [see Warnings and Precautions (5.2)] Active DVT, PE, or a history of these conditions [see Warnings and Precautions (5.1)] Active arterial thromboembolic disease (for example, stroke or MI), or a history of these conditions [see Warnings and Precautions (5.1)] Known anaphylactic reaction, or angioedema, or hypersensitivity to Estradiol Transdermal System Hepatic impairment or disease Protein C, protein S, or antithrombin deficiency, or other known thrombophilic disorders Undiagnosed abnormal genital bleeding (4, 5.2) Breast cancer or a history of breast cancer (4, 5.2) Estrogen-dependent neoplasia (4, 5.2) Active DVT, PE or a history of these conditions (4, 5.1) Active arterial thromboembolic disease (for example, stroke or MI), or a history of these conditions (4, 5.1) Known anaphylactic reaction, or angioedema, or hypersensitivity to Estradiol Transdermal System (4) Hepatic impairment or disease (4, 5.10) Protein C, protein S, or antithrombin deficiency, or other known thrombophilic disorders (4)
Estrogens increase the risk of gallbladder disease (5.4) Discontinue estrogen if severe hypercalcemia, loss of vision, severe hypertriglyceridemia or cholestatic jaundice occurs (5.5, 5.6, 5.9, 5.10) Monitor thyroid function in women on thyroid hormone replacement therapy (5.11, 5.18)
Increased risks of stroke and DVT are reported with estrogen-alone therapy. Increased risks of PE, DVT, stroke and MI are reported with estrogen plus progestin therapy. Immediately discontinue estrogen with or without progestogen therapy if any of these occur or are suspected. Manage appropriately any risk factors for arterial vascular disease (for example, hypertension, diabetes mellitus, tobacco use, hypercholesterolemia, and obesity) and/or venous thromboembolism (VTE) (for example, personal history or family history of VTE, obesity, and systemic lupus erythematosus).
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. After an average follow-up of 5.2 years, 28 women in the estrogen-alone group and 19 women in the placebo group were diagnosed with probable dementia. The relative risk of probable dementia for CE-alone versus placebo was 1.49 (95 percent CI, 0.83-2.66). The absolute risk of probable dementia for CE-alone versus placebo was 37 versus 25 cases per 10,000 women-years8 [see Use in Specific Populations (8.5), and Clinical Studies (14.4)]. In the WHIMS estrogen plus progestin ancillary study, a population of 4,532 postmenopausal women 65 to 79 years of age was randomized to daily CE (0.625 mg) plus MPA (2.5 mg) or placebo. After an average follow-up of 4 years, 40 women in the CE plus MPA group and 21 women in the placebo group were diagnosed with probable dementia.The relative risk of probable dementia for CE plus MPA versus placebo was 2.05 (95 percent CI, 1.21-3.48). The absolute risk of probable dementia for CE plus MPA versus placebo was 45 versus 22 cases per 10,000 women-years8 [see Use in Specific Populations (8.5), and Clinical Studies (14.4)]. When data from the two populations in the WHIMS estrogen-alone and estrogen plus progestin ancillary studies were pooled as planned in the WHIMS protocol, the reported overall relative risk for probable dementia was 1.76 (95 percent CI, 1.19-2.60). Since both ancillary studies were conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women8 [see Use in Specific Populations (8.5), and Clinical Studies (14.4)].
A 2- to 4-fold increase in the risk of gallbladder disease requiring surgery in postmenopausal women receiving estrogens has been reported.
Estrogen administration may lead to severe hypercalcemia in women with breast cancer and bone metastases. Discontinue estrogens, including the Estradiol Transdermal System if hypercalcemia occurs, and take appropriate measures to reduce the serum calcium level.
Retinal vascular thrombosis has been reported in women receiving estrogens. Discontinue The Estradiol Transdermal System pending examination if there is sudden partial or complete loss of vision, or a sudden onset of proptosis, diplopia, or migraine. Permanently discontinue estrogens, including The Estradiol Transdermal System, if examination reveals papilledema or retinal vascular lesions.
Studies of the addition of a progestogen for 10 or more days of a cycle of estrogen administration, or daily with estrogen in a continuous regimen, have reported a lowered incidence of endometrial hyperplasia than would be induced by estrogen treatment alone. Endometrial hyperplasia may be a precursor to endometrial cancer. There are, however, possible risks that may be associated with the use of progestogens with estrogens compared to estrogen-alone regimens. These include an increased risk of breast cancer.
In a small number of case reports, substantial increases in blood pressure have been attributed to idiosyncratic reactions to estrogens. In a large, randomized, placebo-controlled clinical trial, a generalized effect of estrogens on blood pressure was not seen.
In women with pre-existing hypertriglyceridemia, estrogen therapy may be associated with elevations of plasma triglycerides leading to pancreatitis. Discontinue the Estradiol Transdermal System if pancreatitis occurs.
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, discontinue The Estradiol Transdermal System.
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 the Estradiol Transdermal System to maintain their free thyroid hormone levels in an acceptable range.
Estrogens may cause some degree of fluid retention. Monitor any woman with a condition(s) that might predispose her to fluid retention, such as a cardiac or renal impairment. Discontinue estrogen-alone therapy, including the Estradiol Transdermal System, with evidence of medically concerning fluid retention.
Estrogen-induced hypocalcemia may occur in women with hypoparathyroidism. Consider whether the benefits of estrogen therapy, including the Estradiol Transdermal System, outweigh the risks in such women.
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 progestogen therapy for women known to have residual endometriosis post-hysterectomy.
Exogenous estrogens may exacerbate symptoms of angioedema in women with hereditary angioedema. Consider whether the benefits of estrogen therapy, including the Estradiol Transdermal System, outweigh the risks in such women.
Estrogen therapy, including the Estradiol Transdermal System, 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.
Serum follicle stimulating hormone (FSH) and estradiol levels have not been shown to be useful in the management of postmenopausal women with moderate to severe vasomotor symptoms and moderate to severe symptoms of vulvar and vaginal atrophy. Laboratory parameters may be useful in guiding the Estradiol Transdermal System dosage for the treatment of hypoestrogenism due to hypogonadism, castration and primary ovarian failure.
Accelerated prothrombin time, partial thromboplastin time, and platelet aggregation time; increased platelet count; increased factors II, VII antigen, VIII antigen, VIII coagulant activity, IX, X, XII, VII-X complex, II-VII-X complex, and beta-thromboglobulin; decreased levels of antifactor Xa and antithrombin III, decreased antithrombin III activity; increased levels of fibrinogen and fibrinogen activity; increased plasminogen antigen and activity. Increased TBG levels leading to increased circulating total thyroid hormone, as measured by protein-bound iodine (PBI), T4 levels (by column or by radioimmunoassay) or T3 levels by radioimmunoassay. T3 resin uptake is decreased, reflecting the elevated TBG. Free T4 and free T3 concentrations are unaltered. Women on thyroid replacement therapy may require higher doses of thyroid hormone. Other binding proteins may be elevated in serum, for example, corticosteroid binding globulin (CBG), sex hormone-binding globulin (SHBG), leading to increased total circulating corticosteroids and sex steroids, respectively. Free hormone concentrations, such as testosterone and estradiol, may be decreased. Other plasma proteins may be increased (angiotensinogen/renin substrate, alpha-l-antitrypsin, ceruloplasmin). Increased plasma high-density lipoprotein (HDL) and HDL2 cholesterol subfraction concentrations, reduced low-density lipoprotein (LDL) cholesterol concentration, and increased triglyceride levels. Impaired glucose tolerance.
The following serious adverse reactions are discussed elsewhere in the labeling: Cardiovascular Disorders [see Boxed Warning, and Warnings and Precautions (5.1)] Malignant Neoplasms [see Boxed Warning, and Warnings and Precautions (5.2)] The most common adverse reactions ( 10 percent) with the Estradiol Transdermal System are: breast pain, upper respiratory tract infections, headaches, abdominal pain, pain, and edema.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data described below reflect pooled data from 5 clinical trials of the Estradiol Transdermal System. A total of 614 women were exposed to the Estradiol Transdermal System for 3 months (193 women at 0.025 mg per day, 201 women at 0.05 mg per day, 194 women at 0.1 mg per day) in randomized, double-blind trials of clinical efficacy versus placebo and versus active comparator. All women were postmenopausal, had a serum estradiol level of less than 20 pg/mL, and a minimum of five moderate to severe hot flushes per week or a minimum of 15 hot flushes per week of any severity at baseline. Included in this table are an additional 25 postmenopausal hysterectomized women exposed to the Estradiol Transdermal System 0.025 mg per day for 6 to 24 months (N=16 at 24 months) in a randomized, double-blind, placebo-controlled study of the Estradiol Transdermal System for the prevention of osteoporosis.

The following adverse reactions have been identified during post-approval use of the Estradiol Transdermal System. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
In vitro and in vivo studies have shown that estrogens are metabolized partially by cytochrome P450 3A4 (CYP3A4). Therefore, inducers or inhibitors of CYP3A4 may affect estrogen drug metabolism. Inducers of CYP3A4 such as St. John s wort (hypericum perforatum) preparations, phenobarbital, carbamazepine, and rifampin may reduce plasma concentrations of estrogens, possibly resulting in a decrease in therapeutic effects and/or changes in the uterine bleeding profile. Inhibitors of CYP3A4 such as erythromycin, clarithromycin, ketoconazole, itraconazole, ritonavir and grapefruit juice may increase plasma concentrations of estrogens and may result in adverse reactions. Inducers and/or inhibitors of CYP3A4 may affect estrogen drug metabolism and decrease or increase the estrogen plasma concentration. (7)
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 breastfeeding should be considered along with the mother s clinical need for the Estradiol Transdermal System and any potential adverse effects on the breastfed child from the Estradiol Transdermal System or from the underlying maternal condition.
In general, the Estradiol Transdermal System is not indicated for use in pediatric patients. Clinical studies have not been conducted in the pediatric population. If estrogen is administered to patients whose bone growth is not complete, periodic monitoring of bone metabolism and effects on epiphyseal centers is recommended during estrogen administration.
There have not been sufficient numbers of geriatric women involved in clinical studies utilizing the Estradiol Transdermal System to determine whether those over 65 years of age differ from younger subjects in their response to the Estradiol Transdermal System.
Overdosage of estrogen may cause nausea, vomiting, breast tenderness, abdominal pain, drowsiness and fatigue, and withdrawal bleeding in women. Treatment of overdose consists of discontinuation of the Estradiol Transdermal System therapy with institution of appropriate symptomatic care.
The Estradiol Transdermal System (estradiol transdermal system), is designed to release estradiol continuously upon application to intact skin. Six (6.5, 9.375, 12.5, 15, 18.75 and 25 cm2) systems are available to provide nominal in vivo delivery of 0.025, 0.0375, 0.05, 0.06, 0.075 or 0.1 mg respectively of estradiol per day. The period of use is 7 days. Each system has a contact surface area of either 6.5, 9.375, 12.5, 15, 18.75 or 25 cm2, and contains 2, 2.85, 3.8, 4.55, 5.7 or 7.6 mg of estradiol USP respectively. The composition of the systems per unit area is identical. Estradiol USP is a white, crystalline powder, chemically described as estra-1,3,5(10)-triene-3, 17 -diol. It has an empirical formula of C18 H24 O2 and molecular weight of 272.38. The structural formula is: The Estradiol Transdermal System transdermal system comprises three layers. Proceeding from the visible surface toward the surface attached to the skin, these layers are: 1.A translucent polyethylene film. 2.An acrylate adhesive matrix containing estradiol USP. 3.A protective liner of siliconized or fluoropolymer-coated polyester film is attached to the adhesive surface and must be removed before the system can be used. The active component of the transdermal system is estradiol. The remaining components of the transdermal system (acrylate copolymer adhesive, fatty acid esters, and polyethylene backing) are pharmacologically inactive.
Endogenous estrogens are largely responsible for the development and maintenance of the female reproductive system and secondary sexual characteristics. Although circulating estrogens exist in a dynamic equilibrium of metabolic interconversions, estradiol is the principal intracellular human estrogen and is substantially more potent than its metabolites, estrone and estriol at the receptor level. The primary source of estrogen in normally cycling adult women is the ovarian follicle, which secretes 70 to 500 mcg of estradiol daily, depending on the phase of the menstrual cycle. After menopause, most endogenous estrogen is produced by conversion of androstenedione, which is secreted by the adrenal cortex, to estrone in the peripheral tissues. Thus, estrone and the sulfate conjugated form, estrone sulfate, are the most abundant circulating estrogens in postmenopausal women. Estrogens act through binding to nuclear receptors in estrogen-responsive tissues. To date, two estrogen receptors have been identified. These vary in proportion from tissue to tissue. Circulating estrogens modulate the pituitary secretion of the gonadotropins, luteinizing hormone (LH) and FSH, through a negative feedback mechanism. Estrogens act to reduce the elevated levels of these hormones seen in postmenopausal women.
Generally, a serum estrogen concentration does not predict an individual woman s therapeutic response to the Estradiol Transdermal System nor her risk for adverse outcomes. Likewise, exposure comparisons across different estrogen products to infer efficacy or safety for the individual woman may not be valid.
Long-term continuous administration of natural and synthetic estrogens in certain animal species increases the frequency of carcinomas of the breast, uterus, cervix, vagina, testis, and liver.
A study of 214 women 25 to 74 years of age met the qualification criteria and were randomly assigned to one of the three treatment groups: 72 to the 0.05 mg estradiol patch, 70 to the 0.1 mg estradiol patch, and 72 to placebo. Potential participants were postmenopausal women in good general health who experienced vasomotor symptoms. Natural menopause patients had not menstruated for at least 12 months and surgical menopause patients had undergone bilateral oophorectomy at least 4 weeks before evaluation for study entry. In order to enter the 11-week treatment phase of the study, potential participants must have experienced a minimum of five moderate to severe hot flushes per week, or a minimum of 15 hot flushes of any severity per week, for 2 consecutive weeks. Women wore the patches in a cyclical fashion (three weeks on and one week off). During treatment, all women used diaries to record the number and severity of hot flushes. Women were monitored by clinic visits at the end of weeks 1, 3, 7, and 11 and by telephone at the end of weeks 4, 5, 8, and 9. Adequate data for the analysis of efficacy was available from 191 subjects. The results are presented as the mean SD number of flushes in each of the 3 treatment weeks of each 4-week cycle. In the 0.05 mg estradiol group, the mean weekly hot flush rate across all treatment cycles decreased from 46 6.5 at baseline to 20 3 (-67 percent). The 0.1 mg estradiol group had a decline in the mean weekly hot flush rate from 52 4.4 at baseline to 16 2.4 (-72 percent). In the placebo group, the mean weekly hot flush rate declined from 53 4.5 at baseline to 46 6.5 (-18.1 percent). Compared with placebo, the 0.05 mg and 0.1 mg estradiol groups showed a statistically significantly larger mean decrease in hot flushes across all treatment cycles (P<0.05). When the response to treatment was analyzed for each of the three cycles of therapy, similar statistically significant differences were observed between both estradiol treatment groups and the placebo group during all treatment cycles. In a double-blind, placebo-controlled, randomized study of 187 women receiving estradiol 0.025 mg per day or placebo continuously for up to three 28-day cycles, the estradiol 0.025 mg per day dosage was shown to be statistically better than placebo at weeks 4 and 12 for relief of both the frequency and severity of moderate to severe vasomotor symptoms.

A two-year clinical trial enrolled a total of 175 healthy, hysterectomized, postmenopausal, non-osteoporotic (that is, lumbar spine bone mineral density >0.9 gm/cm2) women at 10 study centers in the United States. A total of 129 participating women were allocated to receive active treatment with 4 different doses of estradiol patches (6.5, 12.5, 15, 25 cm2) and 46 participating women were allocated to receive placebo patches. Seventy-seven percent of the randomized women (100 on active drug and 34 on placebo) contributed data to the analysis of percent change of anterior-posterior (A-P) spine BMD, the primary efficacy variable (see Figure 3). A statistically significant overall treatment effect at each timepoint was noted, implying bone preservation for all active treatment groups at all timepoints, as opposed to bone loss for placebo at all timepoints. Figure 3: Mean Percent Change from Baseline in Lumbar Spine (A-P View) Bone Mineral Density By Treatment and Time Last Observation Carried Forward Figure 3: Mean Percent Change from Baseline in Lumbar Spine (A-P View) Bone Mineral Density By Treatment and Time Last Observation Carried Forward Percent change in BMD of the total hip (see Figure 4) was also statistically significantly different from placebo for all active treatment groups. This figure is based on 74 percent of the randomized women (95 on active drug and 34 on placebo).

The WHI enrolled approximately 27,000 predominantly healthy postmenopausal women in two substudies to assess the risks and benefits of daily oral CE (0.625 mg)-alone or in combination with MPA (2.5 mg) compared to placebo in the prevention of certain chronic diseases. The primary endpoint was the incidence of CHD (defined as nonfatal MI, silent MI and CHD death), with invasive breast cancer as the primary adverse outcome. A "global index" included the earliest occurrence of CHD, invasive breast cancer, stroke, PE, endometrial cancer (only in the CE plus MPA substudy), colorectal cancer, hip fracture, or death due to other causes. These substudies did not evaluate the effects of CE-alone or CE plus MPA on menopausal symptoms.
The WHIMS estrogen-alone ancillary study of WHI enrolled 2,947 predominantly healthy hysterectomized postmenopausal women 65 to 79 years of age and older (45 percent were 65 to 69 years of age; 36 percent were 70 to 74 years of age; 19 percent were 75 years of age and older) to evaluate the effects of daily CE (0.625 mg)-alone on the incidence of probable dementia (primary outcome) compared to placebo. After an average follow-up of 5.2 years, the relative risk of probable dementia for CE-alone versus placebo was 1.49 (95 percent CI, 0.83-2.66). The absolute risk of probable dementia for CE-alone versus placebo was 37 versus 25 cases per 10,000 women-years. Probable dementia as defined in the study included Alzheimer s disease (AD), vascular dementia (VaD) and mixed types (having features of both AD and VaD). The most common classification of probable dementia in the treatment group and the placebo group was AD. Since the ancillary study was conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women [see Warnings and Precautions (5.3), and Use in Specific Populations (8.5)]. The WHIMS estrogen plus progestin ancillary study enrolled 4,532 predominantly healthy postmenopausal women 65 years of age and older (47 percent were 65 to 69 years of age; 35 percent were 70 to 74 years of age; and 18 percent were 75 years of age and older) to evaluate the effects of daily CE (0.625 mg) plus MPA (2.5 mg) on the incidence of probable dementia (primary outcome) compared to placebo. After an average follow-up of 4 years, the relative risk of probable dementia for CE plus MPA versus placebo was 2.05 (95 percent CI, 1.21-3.48). The absolute risk of probable dementia for CE plus MPA versus placebo was 45 versus 22 cases per 10,000 women-years. Probable dementia as defined in the study included AD, VaD and mixed types (having features of both AD and VaD). The most common classification of probable dementia in the treatment group and the placebo group was AD. Since the ancillary study was conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women [see Warnings and Precautions (5.3), and Use in Specific Populations (8.5)]. When data from the two populations were pooled as planned in the WHIMS protocol, the reported overall relative risk for probable dementia was 1.76 (95 percent CI, 1.19-2.60). Differences between groups became apparent in the first year of treatment. It is unknown whether these findings apply to younger postmenopausal women [see Warnings and Precautions (5.3), and Use in Specific Populations (8.5)]

Patient Information Estradiol Transdermal System Read this Patient Information before you start using Estradiol Transdermal System and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your menopausal symptoms or your treatment. What is the most important information I should know about the Estradiol Transdermal System (an estrogen hormone)? Using estrogen-alone may increase your chance of getting cancer of the uterus (womb). Report any unusual vaginal bleeding right away while you are using the Estradiol Transdermal System. Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause. Do not use estrogen-alone to prevent heart disease, heart attacks, strokes, or dementia (decline in brain function). Using estrogen-alone may increase your chances of getting strokes or blood clots. Using estrogen-alone may increase your chance of getting dementia, based on a study of women age 65 years of age and older. Do not use estrogens with progestogens to prevent heart disease, heart attacks, strokes or dementia. Using estrogens with progestogens may increase your chances of getting heart attacks, strokes, breast cancer, or blood clots. Using estrogens with progestogens may increase your chance of getting dementia, based on a study of women age 65 years of age and older. Only one estrogen-alone product and dose have been shown to increase your chances of getting strokes, blood clots, and dementia. Only one estrogen with progestogen product and dose have been shown to increase your chances of getting heart attacks, strokes, breast cancer, blood clots, and dementia. Because other products and doses have not been studied in the same way, it is not known how the use of the Estradiol Transdermal System will affect your chances of these conditions. You and your healthcare provider should talk regularly about whether you still need treatment with the Estradiol Transdermal System. What is the Estradiol Transdermal System? the Estradiol Transdermal System is a prescription medicine patch (transdermal system) that contains estradiol (an estrogen hormone). What is the Estradiol Transdermal System used for? The Estradiol Transdermal System is used after menopause to: Reduce moderate to severe hot flashes Estrogens are hormones made by a woman s ovaries. The ovaries normally stop making estrogens when a woman is between 45 and 55 years old. This drop in body estrogen levels causes the "change of life" or menopause (the end of monthly menstrual periods). Sometimes, both ovaries are removed during an operation before natural menopause takes place. The sudden drop in estrogen levels causes "surgical menopause." When estrogen levels begin dropping, some women develop very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden intense feelings of heat and sweating ("hot flashes" or "hot flushes"). In some women, the symptoms are mild, and they will not need to use estrogens. In other women, symptoms can be more severe. Treat moderate to severe menopausal changes in and around the vagina You and your healthcare provider should talk regularly about whether you still need treatment with the Estradiol Transdermal System to control these problems. If you use the Estradiol Transdermal System only to treat your menopausal changes in and around your vagina, talk with your healthcare provider about whether a topical vaginal product would be better for you. Treat certain conditions in women before menopause if their ovaries do not produce enough estrogens naturally Help reduce your chances of getting osteoporosis (thin weak bones) Osteoporosis from menopause is a thinning of the bones that makes them weaker and easier to break. If you use the Estradiol Transdermal System only to prevent osteoporosis due to menopause, talk with your healthcare provider about whether a different treatment or medicine without estrogens might be better for you. You and your healthcare provider should talk regularly about whether you still need treatment with the Estradiol Transdermal System. Who should not use the Estradiol Transdermal System? Do not start using the Estradiol Transdermal System if you: have unusual vaginal bleeding Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause. have been diagnosed with a bleeding disorder currently have or have had certain cancers Estrogens may increase the chance of getting certain types of cancers, including cancer of the breast or uterus (womb). If you have or have had cancer, talk with your healthcare provider about whether you should use the Estradiol Transdermal System. had a stroke or heart attack currently have or have had blood clots currently have or have had liver problems are allergic to the Estradiol Transdermal System or any of the ingredients in it. See the list of ingredients in the Estradiol Transdermal System at the end of this leaflet. Before you use the Estradiol Transdermal System, tell your healthcare provider about all of your medical conditions, including if you: have any unusual vaginal bleeding Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause. have any other medical conditions that may become worse while you are using the Estradiol Transdermal System Your healthcare provider may need to check you more carefully if you have certain conditions, such as asthma (wheezing), epilepsy (seizures), diabetes, migraine, endometriosis, lupus, angioedema (swelling of face and tongue), or problems with your heart, liver, thyroid, kidneys, or have high calcium levels in your blood. are going to have surgery or will be on bed rest. Your healthcare provider will let you know if you need to stop using the Estradiol Transdermal System. are pregnant or think you may be pregnant. the Estradiol Transdermal System is not for pregnant women. are breastfeeding The hormone in the Estradiol Transdermal System can pass into your breast milk. Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Some medicines may affect how the Estradiol Transdermal System works. the Estradiol Transdermal System may also affect how your other medicines work. Keep a list of your medicines and show it to your healthcare provider and pharmacist when you get new medicine. How should I use the Estradiol Transdermal System? For detailed instructions, see the step-by-step instructions for using the Estradiol Transdermal System at the end of this Patient Information. Use the Estradiol Transdermal System exactly as your healthcare provider tells you to use it. the Estradiol Transdermal System is for skin use only. Change your Estradiol Transdermal System patch 1 time each week or every 7 days. Apply your Estradiol Transdermal System patch to a clean, dry area on your lower abdomen or buttocks. This area must be clean, dry, and free of powder, oil or lotion for your patch to stick to your skin. Apply your Estradiol Transdermal System patch to a different area of your abdomen or your buttocks each time. Do not use the same application site 2 times in the same week. Do not apply the Estradiol Transdermal System to your breasts. If you forget to apply a new Estradiol Transdermal System patch, apply a new patch as soon as possible. You and your healthcare provider should talk regularly (every 3 to 6 months) about the dose you are using and whether you still need treatment with the Estradiol Transdermal System. How to Change the Estradiol Transdermal System When changing the Estradiol Transdermal System, peel off the used patch slowly from the skin. After removal of the Estradiol Transdermal System if any adhesive residue remains on your skin, allow the area to dry for 15 minutes. Then, gently rub the area with an oil-based cream or lotion to remove the adhesive from your skin. Apply the new patch to a different area of your abdomen or buttocks. This area must be clean, dry, and free of powder, oil or lotion. Do not use the same site again for at least 1 week after removal of an old patch. What are the possible side effects of the Estradiol Transdermal System? Side effects are grouped by how serious they are and how often they happen when you are treated. Serious, but less common side effects include: Call your healthcare provider right away if you get any of the following warning signs or any other unusual symptoms that concern you: new breast lumps unusual vaginal bleeding changes in vision or speech sudden new severe headaches severe pains in your chest or legs with or without shortness of breath, weakness and fatigue Common side effects of the Estradiol Transdermal System include: headache breast tenderness or pain irregular vaginal bleeding or spotting stomach or abdominal cramps, bloating nausea and vomiting hair loss fluid retention vaginal yeast infection redness and/or irritation at the patch placement site These are not all the possible side effects of the Estradiol Transdermal System. For more information, ask your healthcare provider or pharmacist. Tell your healthcare provider if you have any side effects that bother you or do not go away. You may report side effects to FDA at 1-800-FDA-1088. You may report side effects to Bayer Healthcare Pharmaceuticals at 1-888-842-2937. What can I do to lower my chances of a serious side effect with the Estradiol Transdermal System? Talk with your healthcare provider regularly about whether you should continue using the Estradiol Transdermal System. If you have a uterus, talk with your healthcare provider about whether the addition of a progestogen is right for you. In general, the addition of a progestogen is generally recommended for a woman with a uterus to reduce the chance of getting cancer of the uterus (womb). See your healthcare provider right away if you get vaginal bleeding while using the Estradiol Transdermal System. Have a pelvic exam, breast exam and mammogram (breast X-ray) every year unless your healthcare provider tells you something else. If members of your family have had breast cancer or if you have ever had breast lumps or an abnormal mammogram, you may need to have breast exams more often. If you have high blood pressure, high cholesterol (fat in the blood), diabetes, are overweight, or if you use tobacco, you may have higher chances for getting heart disease. Ask your healthcare provider for ways to lower your chances of getting heart disease. How should I store and throw away the used Estradiol Transdermal System? Store the Estradiol Transdermal System at room temperature 68 F to 77 F (20 C to 25 C). Do not store the Estradiol Transdermal System patches outside of their pouches.
