Adverse reactions
Information about undesirable effects, reasonably associated with use of the drug, that may occur as part of the pharmacological action of the drug or may be unpredictable in its occurrence. Adverse reactions include those that occur with the drug, and if applicable, with drugs in the same pharmacologically active and chemically related class. There is considerable variation in the listing of adverse reactions. They may be categorized by organ system, by severity of reaction, by frequency, by toxicological mechanism, or by a combination of these.6 ADVERSE REACTIONS 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 (≥ 5 percent) in any ELESTRIN treatment group are: breast tenderness, metrorrhagia, nasopharyngitis, and upper respiratory tract infections. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Meda at 1-877-999-8401 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Trials Experience 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. ELESTRIN was studied in a placebo-controlled trial that included a total of 484 postmenopausal women. The adverse reactions that occurred at a rate greater than 5 percent in any of the treatment groups are summarized in Table 1.

Drug and or laboratory test interactions
Information about any known interference by the drug with laboratory tests.5.21 Drug-Laboratory Test Interactions • 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 anti-factor Xa and antithrombin III, decreased antithrombin III activity; increased levels of fibrinogen and fibrinogen activity; increased plasminogen antigen and activity. • Increased thyroid binding globulin (TBG) levels leading to increased circulating total thyroid hormone levels as measured by protein-bound iodine (PBI), T 4 levels (by column or by radioimmunoassay) or T 3 levels by radioimmunoassay. T 3 resin uptake is decreased, reflecting the elevated TBG. Free T 4 and free T 3 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-1-antitrypsin, ceruloplasmin). • Increased plasma high-density lipoprotein (HDL) and HDL 2 cholesterol subfraction concentrations, reduced low-density lipoprotein (LDL) cholesterol concentration, and increased triglycerides levels. • Impaired glucose tolerance.
ELESTRIN Drug Interactions
Information about and practical guidance on preventing clinically significant drug/drug and drug/food interactions that may occur in people taking the drug.7 DRUG INTERACTIONS 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 result in adverse reactions. • Inducers and/or inhibitors of CYP3A4 may affect estrogen drug metabolism and decrease or increase the estrogen plasma concentrations ( 7 )
Clinical pharmacology
Information about the clinical pharmacology and actions of the drug in humans.12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action 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, 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. 12.2 Pharmacodynamics Generally, a serum estrogen concentration does not predict an individual woman’s therapeutic response to ELESTRIN 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. 12.3 Pharmacokinetics Absorption Steady-state serum concentrations of estradiol are achieved in approximately 3 days following daily application of ELESTRIN to the upper arm. Pharmacokinetic parameters for estradiol on Day 14 following daily application of 0.87 g or 1.7 g of ELESTRIN are summarized in Table 2. Dose dependent PK parameters for ELESTRIN 0.87 g and 1.7 g indicated the dose and serum estradiol (E2) concentrations to be linearly related but not dose-proportional (i.e., doubling in dose led to a 2.5- to 3.0-fold increase in PK parameters). The nominal mean delivery rates of estradiol using the baseline-adjusted average serum concentrations from pharmacokinetic studies using 0.87 g per day and 1.7 g per day are 0.0125 mg per day and 0.0375 mg per day, respectively. TABLE 2 - Summary of Unadjusted PK Parameters for Estradiol after 14 Days of Dosing Pharmacokinetic Parameter 0.87 g ELESTRIN (0.52 mg/d Estradiol) Mean 1.7 g ELESTRIN (1.04 mg/d Estradiol) Mean AUC 0-24 (pg’hr/mL) 335.2 940.2 C max (pg/mL) 21.6 66.7 C ave (pg/mL) 15.4 39.2 C min (pg/mL) 9.4 21.1 T max (h) T max shown as median (range) 18 (1 - 20) 4 (1 - 20) Fluctuation Index 0.80 1.16 E2:E1 E2:E1 (estradiol:estrone) ratio ratio 0.53 0.98 Mean concentrations of estradiol over a 24-hour period on Day 14 are shown in Figure 1. Based on the C ave values at steady state, the E2:E1 ratio was 0.53 for the 0.87 g and 0.98 for the 1.7 g doses. The significance of this finding is that the 1.7 g dose produced an E2:E1 ratio of a premenopausal woman. The 1.7 g dose of ELESTRIN reached the goal of restoring the E2:E1 ratio (~1.0) to that observed in premenopausal women in the early follicular phase of the menstrual cycle. Application of sunscreen 10 minutes before application of ELESTRIN increased the exposure to estradiol by approximately 55 percent. No significant change in estradiol exposure was observed when sunscreen was applied 25 minutes after application of ELESTRIN. In the same study, prolonged (7 days) concomitant application of sunscreen to the site of ELESTRIN application increased exposure to estradiol by about 2-fold, regardless of whether it was applied before or after application of ELESTRIN. elestrin-graph Distribution The distribution of exogenous estrogens is similar to that of endogenous estrogens. Estrogens are widely distributed in the body and are generally found in higher concentrations in the sex hormone target organs. Estrogens circulate in blood largely bound to SHBG and albumin. Metabolism Exogenous estrogens are metabolized in the same manner as endogenous estrogens. Circulating estrogens exist in a dynamic equilibrium of metabolic interconversions. These transformations take place mainly in the liver. Estradiol is converted reversibly to estrone, and both can be converted to estriol, which is a major urinary metabolite. Estrogens also undergo enterohepatic recirculation via sulfate and glucuronide conjugation in the liver, biliary secretion of conjugates into the intestine, and hydrolysis in the intestine followed by reabsorption. In postmenopausal women, a significant proportion of the circulating estrogens exist as sulfate conjugates, especially estrone sulfate, which serves as a circulating reservoir for the formation of more active estrogens. Excretion Estradiol, estrone and estriol are excreted in the urine along with glucuronide and sulfate conjugates. Potential for Estradiol Transfer The potential for estradiol transfer between treated postmenopausal female subjects and their untreated male partners was evaluated. Two and 8 hours after women applied 2.6 g ELESTRIN to one arm (12 women per time point), they engaged in direct arm-to-arm contact with a male partner for 5 minutes. No significant changes in estradiol pharmacokinetic parameters were observed in the male partners after contact. Less than 10 percent of the estradiol dose was measured on the skin at 2 and 8 hours after application. After washing the application site with soap and water at 8 hours after application, about 1 percent of the dose of estradiol was measurable.

Dosage and administration
Information about the drug product’s dosage and administration recommendations, including starting dose, dose range, titration regimens, and any other clinically sigificant information that affects dosing recommendations.2 DOSAGE AND ADMINISTRATION Generally, when estrogen is prescribed for a postmenopausal woman with a uterus, consider addition of a progestin to reduce the risk of endometrial cancer. Generally, a woman without a uterus does not need to take a progestin in addition to her estrogen therapy. In some cases, however, hysterectomized women who have a history of endometriosis may need a progestin [see Warnings and Precautions (5.2) , (5.14) ] . Use estrogen-alone, or in combination with a progestin, 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. ELESTRIN is applied onto the skin in a thin layer. The recommended area of application is the upper arm to shoulder (approximately 320 cm 2 ). Start therapy with daily administration of one pump actuation to deliver 0.87 grams of gel providing 0.52 mg estradiol to the upper arm. Dosage adjustment should be guided by the clinical response ( 2.1 ) 2.1 Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause ELESTRIN is applied once daily to the upper arm for the treatment of moderate to severe vasomotor symptoms due to menopause using a metered-dose pump which delivers 0.87 grams of estradiol gel (0.52 mg estradiol) per actuation (1 pump). Start therapy with one pump per day (0.87 grams per day, which contains 0.52 mg of estradiol). Make dosage adjustments based on clinical response.

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 or older • Do not use estrogens with progestins to prevent heart disease, heart attacks, strokes or dementia • Using estrogens with progestins may increase your chances of getting heart attacks, strokes, breast cancer, or blood clots • Using estrogens with progestins may increase your chance of getting dementia, based on a study of women age 65 years or 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 progestin 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 ELESTRIN will affect your chances of these conditions. You and your healthcare provider should talk regularly about whether you still need treatment with ELESTRIN. What is ELESTRIN? ELESTRIN is a prescription medicine in a colorless gel that contains the estrogen hormone estradiol. When applied to the skin, estradiol is absorbed through the skin into the blood stream. What is ELESTRIN used for? ELESTRIN 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 to 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 estrogens. In other women, symptoms can be more severe. You and your healthcare provider should talk regularly about whether you still need treatment with ELESTRIN. Who should not use ELESTRIN? Do not start ELESTRIN 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 chances 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 ELESTRIN. • had a stroke or heart attack • currently have or have had blood clots • currently have or have had liver problems • are allergic to ELESTRIN or any of its ingredients See the list of ingredients in ELESTRIN at the end of this leaflet Before you use ELESTRIN, 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 ELESTRIN 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), 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 You may need to stop using ELESTRIN. • are pregnant or think you may be pregnant ELESTRIN is not for pregnant women. • are breastfeeding The hormone in ELESTRIN 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 ELESTRIN works. ELESTRIN 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 ELESTRIN? • Start at the lowest dose and talk to your healthcare provider about how well that dose is working for you. • ELESTRIN should be used at the lowest dose possible for your treatment and only as long as needed. You and your healthcare provider should talk regularly (for example, every 3 to 6 months) about the dose you are taking and whether you still need treatment with ELESTRIN. • ELESTRIN comes in a metered-dose pump. One dose of ELESTRIN is released each time the pump is depressed (pressed down). • Use ELESTRIN exactly how your healthcare provider tells you. • The ELESTRIN pump contains enough of the medicine to let you prime the pump (get the pump ready) before you use it the first time. To prime the pump, push the head of the pump down slowly, then remove your finger from the pump head and allow it to spring back automatically (by itself). Repeat this until the gel comes out. Throw away this first amount of gel as it will not be a full dose. Once the pump head has come all the way back up, the pump is now primed and ready to use. With each dose, remember to push the pump head down slowly and allow it to spring back automatically. Let the pump head come all the way back up before you push it down again. If using more than 1 dose, wait 5 seconds before pumping the next dose. This will make sure that the pump works correctly and gives your full dose of ELESTRIN. Use the pump a total of 30 times (30 pushes) as your healthcare provider tells you. After you have initially primed the pump and have used a total of 30 doses of ELESTRIN, you will need to throw the pump away and use a new one. The correct amount of medicine in each dose cannot be assured after 30 doses have been used, even though the pump container is not completely empty. Important things to remember when using ELESTRIN • Wash your hands with soap and water after applying the gel to reduce the chance that the medicine will be spread from your hands to other people. • Allow the gel to dry for five minutes or more before dressing. Try to keep the area dry for as long as possible. • Do not allow others to come in contact with the area of skin where you applied the gel for at least two hours after you apply ELESTRIN. • Always move the spout into locked position and place the cap over the top of the pump after each use. • Never apply ELESTRIN to the breast. Never apply ELESTRIN in or around the vagina. • Do not allow others to apply the gel for you. • Do not apply sunscreen to the area where the gel was applied for at least 25 minutes. • Do not apply sunscreen to the area where the gel was applied for 7 or more consecutive days. • Avoid fire, flame or smoking until the gel has dried. ELESTRIN contains alcohol. Alcohol based gels are flammable. • It is important that you read and follow the detailed “Patient Instructions for Use” at the end of this leaflet on how to use the ELESTRIN pump and apply the dose. What should I do if someone else is exposed to ELESTRIN? If someone else is exposed to ELESTRIN by direct contact with the gel, that person should wash the area of contact with soap and water as soon as possible. The longer the gel is in contact with the skin before washing, the greater is the chance that the other person will absorb some of the estrogen hormone. This is especially important for men and children. What should I do if I get ELESTRIN in my eyes? If you get ELESTRIN in your eyes, rinse your eyes right away with warm clean water to flush out any ELESTRIN. Seek medical attention if needed. What should I do if I miss a dose? If you miss a dose, do not double the dose on the next day to catch up. If your next dose is less than 12 hours away, it is best just to wait and apply your normal dose the next day. If it is more than 12 hours until the next dose, apply the dose you missed and resume your normal dosing the next day. What are the possible side effects of ELESTRIN? 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: • Heart attack • Stroke • Blood clots • Cancer of the lining of the uterus (womb) • Breast cancer • Cancer of the ovary • Dementia • Gallbladder disease • High or low blood calcium • Visual abnormalities • High blood pressure • High levels of fat (triglyceride) in your blood • Liver problems • Changes in your thyroid levels • Fluid retention • Cancer change of endometriosis • Enlargement of benign tumors of the uterus (“fibroids”) • Worsening of swelling of the face and tongue (angioedema) in women with a history of angioedema 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 ELESTRIN include: • Irregular vaginal bleeding or spotting • Nausea and vomiting • Vaginal yeast infection • Headache • Stomach or abdominal cramps, bloating • Breast pain • Hair loss • Fluid retention These are not all the possible side effects of ELESTRIN. For more information, ask your healthcare provider or pharmacist. You may report side effects to Meda Pharmaceuticals Inc. at 1-877-999-8401 or to FDA at 1-800-FDA-1088. What can I do to lower my chances of a serious side effect with ELESTRIN? • Talk with your healthcare provider regularly about whether you should continue using ELESTRIN • If you have a uterus, talk to your healthcare provider about whether the addition of a progestin is right for you. The addition of a progestin 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 ELESTRIN. • 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 a higher chance for getting heart disease Ask your healthcare provider for ways to lower your chances of getting heart disease. General information about safe and effective use of ELESTRIN Medicines are sometimes prescribed for conditions that are not mentioned in patient information leaflets. Do not use ELESTRIN for conditions for which it was not prescribed. Do not give ELESTRIN to other people, even if they have the same symptoms you have. It may harm them. Keep ELESTRIN out of the reach of children This leaflet provides a summary of the most important information about ELESTRIN. If you would like more information, talk with your healthcare provider or pharmacist. You can ask for information about ELESTRIN that is written for health professionals. You can get more information by calling 1-877-999-8401 (toll free). What are the ingredients in ELESTRIN? Active ingredient: estradiol. Inactive ingredients: purified water, ethanol, propylene glycol, diethylene glycol monoethyl ether, carbomer homopolymer type C, triethanolamine, and edetate disodium.

Clinical studies
This field may contain references to clinical studies in place of detailed discussion in other sections of the labeling.14 CLINICAL STUDIES 14.1 Effects on Vasomotor Symptoms in Postmenopausal Women A randomized, double-blind, placebo-controlled clinical trial evaluated the efficacy of 12-week treatment with three different daily doses of ELESTRIN for the treatment of vasomotor symptoms in 484 postmenopausal women between 28 and 74 years of age (mean 54 years; 83-88 percent Caucasian per group) who had at least 60 moderate-to-severe hot flushes per week at baseline. At baseline, mean hot flushes is 13 per day, mean serum estradiol is 11.2-13.2 pg/mL, and prior hormone/estrogen therapy is 75.7-84.5 percent. Participants applied placebo, 1.7 g (1.04 mg estradiol), or 2.6 g (1.56 mg estradiol) once daily to the upper arm. The study was amended to identify the lowest effective dose of ELESTRIN and limit the number of women exposed to the 2.6 g dose. After the study amendment, ELESTRIN 0.87 g (0.52 mg estradiol) was added and the 2.6 g was discontinued from further enrollment. Reduction in both the frequency and severity of moderate to severe hot flushes was statistically significant for the ELESTRIN 1.7 g per day dose compared to placebo at week 4. Statistically significant reductions in both the frequency and severity of moderate to severe hot flushes when compared to placebo were delayed for the ELESTRIN 0.87 g per day dose to week 5. Both the 0.87 g per day and 1.7 g per day doses were statistically significant compared to placebo at week 12. Statistically significant reductions in the frequency and severity of daily moderate-to-severe hot flush rate compared to placebo were noted beginning at week 3 for the 1.7 g per day ELESTRIN treatment (data on file). The reductions in frequency and severity are shown in Table 3.

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 cause. These substudies did not evaluate the effects of CE-alone or CE plus MPA on menopausal symptoms. WHI Estrogen-Alone Substudy The WHI estrogen-alone substudy was stopped early because an increased risk of stroke was observed, and it was deemed that no further information would be obtained regarding the risk and benefits of estrogen-alone in predetermined endpoints. Results of the estrogen-alone substudy, which included 10,739 women (average 63 years of age, range 50 to 79; 75.3 percent White, 15.1 percent Black, 6.1 percent Hispanic, 3.6 percent Other), after an average follow-up of 7.1 years are presented in Table 4.

There was no difference between the groups in terms of all-cause mortality. No overall difference for primary CHD events (nonfatal MI, silent MI and CHD death) and invasive breast cancer incidence in women receiving CE-alone compared with placebo was reported in final centrally adjudicated results from the estrogen-alone substudy, after an average follow-up of 7.1 years. Centrally adjudicated results for stroke events from the estrogen-alone substudy, after an average follow-up of 7.1 years, reported no significant difference in the distribution of stroke subtype and severity, including fatal strokes, in women receiving estrogen-alone compared to placebo. Estrogen-alone therapy increased the risk of ischemic stroke, and this excess risk was present in all subgroups of women examined. 10 Timing of initiation of estrogen-alone therapy relative to the start of menopause may affect the overall risk benefit profile. The WHI estrogen-alone substudy stratified by age showed in women 50 to 59 years of age a non-significant trend toward reduced risk for CHD [ hazard ratio (HR) 0.63 (95 percent CI, 0.36-1.09) ] and overall mortality [ HR 0.71 (95 percent CI, 0.46–1.11) ]. WHI Estrogen Plus Progestin Substudy 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, 6.8 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.

The WHI estrogen plus progestin substudy stratified by age showed in women 50 to 59 years of age a non-significant trend toward reduced risk for overall mortality [ HR 0.69 (95 percent CI, 0.44-1.07) ]. 14.3 Women’s Health Initiative Memory Study The WHIMS estrogen-alone ancillary study of WHI enrolled 2,947 predominantly healthy hysterectomized postmenopausal women 65 to 79 years of age (45 percent were 65 to 69 years of age, 36 percent were 70 to 74 years of age, and 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 type (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) ].

Geriatric use
Information about any limitations on any geriatric indications, needs for specific monitoring, hazards associated with use of the drug in the geriatric population.8.5 Geriatric Use There have not been sufficient numbers of geriatric women involved in clinical studies utilizing ELESTRIN to determine whether those over 65 years of age differ from younger subjects in their response to ELESTRIN. The Women’s Health Initiative Study In the WHI estrogen-alone substudy (daily CE [0.625 mg]-alone versus placebo), there was a higher relative risk of stroke in women greater than 65 years of age [see Clinical Studies (14.2) ] . In the WHI estrogen plus progestin substudy (daily CE [0.625 mg] plus MPA [2.5 mg] versus placebo), there was a higher relative risk of nonfatal stroke and invasive breast cancer in women greater than 65 years of age [see Clinical Studies (14.2) ] . The Women’s Health Initiative Memory Study In the WHIMS ancillary studies of postmenopausal women 65 to 79 years of age, there was an increased risk of developing probable dementia in women receiving estrogen-alone or estrogen plus progestin when compared to placebo [see Warnings and Precautions (5.3) , and Clinical Studies (14.3) ] . Since both ancillary studies were conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women 8 [see Warnings and Precautions (5.3) , and Clinical Studies (14.3) ] .
Pediatric use
Information about any limitations on any pediatric indications, needs for specific monitoring, hazards associated with use of the drug in any subsets of the pediatric population (such as neonates, infants, children, or adolescents), differences between pediatric and adult responses to the drug, and other information related to the safe and effective pediatric use of the drug.8.4 Pediatric Use ELESTRIN is not indicated in pediatric patients. Clinical studies have not been conducted in the pediatric population.
Pregnancy
Information about effects the drug may have on pregnant women or on a fetus. This field may be ommitted if the drug is not absorbed systemically and the drug is not known to have a potential for indirect harm to the fetus. It may contain information about the established pregnancy category classification for the drug. (That information is nominally listed in the teratogenic_effects field, but may be listed here instead.)8.1 Pregnancy 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.
Use in specific populations
Information about use of the drug by patients in specific populations, including pregnant women and nursing mothers, pediatric patients, and geriatric patients.8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy 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 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 ELESTRIN is not indicated in pediatric patients. Clinical studies have not been conducted in the pediatric population. 8.5 Geriatric Use There have not been sufficient numbers of geriatric women involved in clinical studies utilizing ELESTRIN to determine whether those over 65 years of age differ from younger subjects in their response to ELESTRIN. The Women’s Health Initiative Study In the WHI estrogen-alone substudy (daily CE [0.625 mg]-alone versus placebo), there was a higher relative risk of stroke in women greater than 65 years of age [see Clinical Studies (14.2) ] . In the WHI estrogen plus progestin substudy (daily CE [0.625 mg] plus MPA [2.5 mg] versus placebo), there was a higher relative risk of nonfatal stroke and invasive breast cancer in women greater than 65 years of age [see Clinical Studies (14.2) ] . The Women’s Health Initiative Memory Study In the WHIMS ancillary studies of postmenopausal women 65 to 79 years of age, there was an increased risk of developing probable dementia in women receiving estrogen-alone or estrogen plus progestin when compared to placebo [see Warnings and Precautions (5.3) , and Clinical Studies (14.3) ] . Since both ancillary studies were conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women 8 [see Warnings and Precautions (5.3) , and Clinical Studies (14.3) ] .

Boxed warning
Information about contraindications or serious warnings, particularly those that may lead to death or serious injury.WARNING: ENDOMETRIAL CANCER, CARDIOVASCULAR DISORDERS, PROBABLE DEMENTIA and BREAST CANCER 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 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 [see Warnings and Precautions (5.2) ] . Cardiovascular Disorders and Probable Dementia 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 (14.2 , 14.3) ] . 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 (14.2) ] . 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 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 [see Warnings and Precautions (5.3) , Use in Specific Populations (8.5) , and Clinical Studies (14.3) ] . Only daily oral 0.625 mg CE was studied in the estrogen-alone substudy of 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 progestins 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 Do not use estrogen plus progestin therapy for the prevention of cardiovascular disease or dementia [see Warnings and Precautions (5.1 , 5.3) , and Clinical Studies (14.2 , 14.3) ] . 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 (14.2) ] . 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 [ see Warnings and Precautions (5.3) , Use in Specific Populations (8.5) , and Clinical Studies (14.3) ] . 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 (14.2) ]. Only daily oral 0.625 mg CE and 2.5 mg MPA were studied in the estrogen plus progestin substudy of 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 progestin 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 progestin therapy, taking into account her individual risk profile. 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.
