Adverse Reactions

6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling: • Cardiovascular Disorders [see Boxed Warning, Warnings and Precautions (5.1)] • Malignant Neoplasms [see Boxed Warning, Warnings and Precautions (5.2)] The most common adverse reactions (≥ 5 percent) with Evamist are: headache, breast tenderness and nipple pain, nausea, back pain, and nasopharyngitis. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Padagis at 1-866-634-9120 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 clinical practice. In a 12-week, randomized, placebo-controlled trial of Evamist in 454 women, 80 to 90 percent of women randomized to active drug received at least 70 days of therapy and 75 to 85 percent randomized to placebo received at least 70 days of therapy. The adverse reactions that occurred in at least 5 percent of women in any treatment group are shown in Table 1. Table 1.

Description

11 DESCRIPTION Evamist (estradiol transdermal spray) is designed to deliver estradiol to the blood circulation following topical application to the skin of a rapidly drying solution from a metered-dose pump. Evamist is a homogeneous solution of 1.7% estradiol USP (active ingredient) in alcohol USP and octisalate USP formulated to provide sustained release of the active ingredient into the systemic circulation. Estradiol USP is a white crystalline powder, chemically described as estra-1,3,5(10)-triene- 3,17β-diol. It has an empirical formula of C 18 H 24 O 2 •1/2 H 2 O and molecular weight of 281.4. The structural formula is Each metered-dose pump contains 8.1 mL and is designed to deliver 56 sprays of 90 mcL each after priming. One spray of Evamist contains 1.53 mg estradiol. The metered-dose pump should be held upright and vertical for spraying. Before a new applicator is used for the first time, the pump should be primed by spraying 3 times with the cover on. One, two or three sprays are applied daily each morning to adjacent non-overlapping 20 cm 2 areas on the inner surface of the arm between the elbow and the wrist and allowed to dry. Structural Formula

Dosage And Administration

2 DOSAGE AND ADMINISTRATION 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, 5.15)] . 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. Re-evaluate postmenopausal women periodically as clinically appropriate to determine whether treatment is still necessary. • Start therapy with one spray of Evamist once daily each morning to forearm ( 2.1 ) • Dosage adjustment to two or three sprays of Evamist should be guided by the clinical response ( 2.1 ) 2.1 Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause Start Evamist therapy with one spray of Evamist per day. Make dosage adjustment based on the clinical response. Prime the Evamist container by spraying 3 sprays with the cover on before applying the first dose from a new applicator. Hold the container upright and vertical for spraying. Apply one, two or three sprays each morning to adjacent, non-overlapping areas on the inner surface of the forearm, starting near the elbow. Allowed the sprays to dry for approximately 2 minutes before covering the site with clothing. Do not wash the application site for at least one hour. Application of Evamist to other skin surfaces has not been adequately studied. Evamist should not be applied to skin surfaces other than the forearm. Strict adherence to the following precautions is advised in order to minimize the potential for secondary exposure to estradiol from Evamist-treated skin. Cover the Evamist application site with clothing if another person may come into contact with that area of skin after the spray dries. Additional precautions to minimize unintentional secondary exposure are outlined in Patient Counseling Information [see Patient Counseling Information] and in the Patient Information Leaflet at the end of the prescribing information.

Drug Interactions

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 may result in adverse reactions. • Inducers and inhibitors of CYP3A4 may affect estrogen drug metabolism and decrease or increase the estrogen plasma concentration. (7.1)

Clinical Pharmacology

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 Evamist 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 In a multiple-dose study, 72 postmenopausal women were treated for 14 days with Evamist to the inner forearm. Serum concentrations of estradiol appeared to reach steady state after 7 to 8 days of application of one, two, or three 90 mcL sprays of Evamist per day (Figure 1). Figure 1. Mean (±SD) Serum Estradiol Concentrations on Day 14 Following Topical Application for 14 Days of One, Two or Three Sprays of Evamist (Unadjusted for Baseline) Pharmacokinetics parameters for estradiol from one, two, or three 90 mcL sprays of Evamist, as assessed on Day 14 of this study, are described in Table 2.

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 effect of estradiol transfer was evaluated in 20 healthy postmenopausal women who applied three 90-mcL sprays of Evamist to the inner forearm once daily. One hour after applying Evamist, subjects held the dosed forearm against the inner forearm of a non-dosed (recipient) male subject for one 5-minute period of continual contact. A 4% increase in serum estradiol exposure was observed in persons who came in contact with the application site. The possibility of unintentional secondary exposure to Evamist should be brought to the attention of physicians and Evamist users. Effect of Application Site Washing Site washing with warm water and soap one hour after the application of three 90 mcL sprays to the inner forearm did not have a significant effect on average 24-hour serum concentrations of estradiol.

Instructions For Use

Instructions for Use EVAMIST (EE-vuh-mist) (estradiol transdermal spray) Read this Instructions for Use before you start using EVAMIST 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. The parts of your EVAMIST applicator EVAMIST comes in a spray applicator that delivers a measured amount of estradiol to your skin with each spray (see Figure A). Step 1. Priming your EVAMIST • Before you use your EVAMIST applicator for the first time, the applicator must be primed. • Hold the EVAMIST applicator upright. Keep the cover on. Fully press down the pump button 3 times with your thumb or index finger (see Figure B). After priming, the EVAMIST applicator is ready to use. • The EVAMIST applicator should be primed only 1 time when you first start using a new applicator. Do not prime the EVAMIST applicator before your dose each day. Step 2. Using your EVAMIST • Remove the plastic cover. • Apply EVAMIST to a clean, dry, unbroken skin area on the inside of your forearm between the elbow and the wrist (see Figure C). This area must be clean, dry, and the skin must be without open wounds, cuts, abrasions, or rashes. • Hold the EVAMIST applicator upright and rest the plastic cone flat against your skin. You may need to change the position of your arm or the position of the cone on your arm so that the cone is flat against your skin and there are no gaps between the cone and your skin (see Figure C). • Press the pump button down fully 1 time (see Figure C). If your healthcare provider tells you to increase your dose to 2 or 3 sprays, move the cone before applying the second or third spray to an area of your skin next to but not touching the area of the previous spray (see Figure D). • Do not apply EVAMIST to your breasts or in and around your vagina. • Do not massage or rub EVAMIST into your skin. • Let EVAMIST spray dry on your skin for at least: o 2 minutes before you cover your skin with clothing. o 1 hour before you wash your skin. Step 3. After you use EVAMIST • Place the plastic cover back on the EVAMIST applicator cone. • EVAMIST is flammable until dry. Avoid fire, flame, or smoking until the area of your skin where you have applied EVAMIST has completely dried. Step 4. Throwing away used EVAMIST applicators • Your EVAMIST applicator contains enough medicine to allow for initial priming of the pump with 3 sprays and application of 56 sprays. • Do not use your EVAMIST applicator for more than 56 application sprays even though the bottle may not be completely empty. You may not get the correct dose. • Always replace the cover over the cone of your EVAMIST applicator before you throw it away to prevent accidental exposure to other people or pets. This Patient Information and Instructions for Use have been approved by the U.S. Food and Drug Administration.

Patient Information EVAMIST (EE-vuh-mist) (estradiol transdermal spray) Read this Patient Information before you start using EVAMIST 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 EVAMIST (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 EVAMIST. 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 65 years and older. • Do not use estrogens with progestogens to prevent heart disease, heart attack, 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 65 years and older. • The estrogen in EVAMIST spray can transfer from the area of skin where it was sprayed to other people. Do not allow others, especially children, to come into contact with the area of your skin where you sprayed EVAMIST. Young children who are accidentally exposed to estrogen through contact with women using EVAMIST may show signs of puberty that are not expected (for example, breast budding). • 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 EVAMIST will affect your chances of these conditions. You and your healthcare provider should talk regularly about whether you still need treatment with EVAMIST. Report any unusual vaginal bleeding right away while you are using EVAMIST. 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 65 years and older. Do not use estrogens with progestogens to prevent heart disease, heart attack, 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 65 years and older. The estrogen in EVAMIST spray can transfer from the area of skin where it was sprayed to other people. Do not allow others, especially children, to come into contact with the area of your skin where you sprayed EVAMIST. Young children who are accidentally exposed to estrogen through contact with women using EVAMIST may show signs of puberty that are not expected (for example, breast budding). 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 EVAMIST will affect your chances of these conditions. You and your healthcare provider should talk regularly about whether you still need treatment with EVAMIST. What is EVAMIST? EVAMIST is a prescription medicine spray that contains estradiol (an estrogen hormone). What is EVAMIST used for? EVAMIST spray 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 get 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. You and your healthcare provider should talk regularly about whether you still need treatment with EVAMIST. Who should not use EVAMIST? Do not start using EVAMIST 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 EVAMIST. • had a stroke or heart attack. • currently have or have had blood clots. • currently have or have had liver problems. • are allergic to EVAMIST or any of its ingredients. See the list of ingredients in EVAMIST at the end of this leaflet Before you use EVAMIST, 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 vaginal bleeding to find out the cause. • have any other medical conditions that may become worse while you are using EVAMIST. 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 or 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 EVAMIST. • are pregnant or think you may be pregnant. EVAMIST is not for pregnant women. • are breastfeeding. The hormone in EVAMIST 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 EVAMIST works. Some other medicines and food products may increase or decrease the concentration of the hormone in EVAMIST in the blood. EVAMIST may affect how your other medicines work, and other medicines may affect how EVAMIST works. Keep a list of your medicines and show it to your healthcare provider and pharmacist when you get a new medicine. How should I use EVAMIST? For detailed instructions, see the step-by-step instructions for using EVAMIST at the end of this Patient Information. • Use EVAMIST exactly as your healthcare provider tells you to use it. • EVAMIST is for skin use only. • Apply EVAMIST at the same time each day. • If you use sunscreen 1 hour after you use EVAMIST, it may reduce the amount of EVAMIST absorbed by your skin. • The estrogen in EVAMIST spray can transfer from the area of skin where it was sprayed to other people or pets. Do not allow other people, especially children to come into contact with the area of your skin where you have sprayed EVAMIST. • If another person accidentally touches the area of your skin where you have sprayed EVAMIST, that area of their skin should be washed with soap and water right away. • Do not let pets lick or touch your arm where you have sprayed EVAMIST, especially small pets. EVAMIST may harm them. Cover your skin with clothing where you have sprayed EVAMIST if you think a pet could come in contact with that area of your skin. • If a pet accidentally comes in contact with the area of your skin where you have sprayed EVAMIST, the area of the pet’s skin should be washed with soap and water right away. • Young children who are accidentally exposed to estrogen through contact with women using EVAMIST may show signs and symptoms of puberty that are not expected. Signs and symptoms in children of exposure to EVAMIST may include: o breast budding or breast lumps o other signs of abnormal sexual development If a child shows signs and symptoms of accidental exposure to EVAMIST: o have the child checked right away by their healthcare provider. o stop using EVAMIST and call your healthcare provider right away. o talk to your healthcare provider about the correct use of EVAMIST when around children. • Talk to your healthcare provider about other treatments for your menopause symptoms if accidental exposure to EVAMIST cannot be avoided. • 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 EVAMIST. What should I avoid while using EVAMIST? • Do not allow others to make contact with the area of skin where you have applied the EVAMIST spray. • EVAMIST contains alcohol, which is flammable. Avoid fire, flame, or smoking until the area of your skin where you have applied EVAMIST has dried. What are the possible side effects of EVAMIST? 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 • breast cancer • cancer of the lining of the uterus (womb) • cancer of the ovary • dementia • gallbladder disease • high or low calcium levels • changes in vision • high blood pressure • high levels of fat in your blood (triglycerides) • liver problems • changes in thyroid hormone levels • swelling or fluid retention • cancer changes of endometriosis • enlargement of benign tumors of the uterus (“fibroids”) • worsening swelling of face or tongue (angioedema) in women who have a history of angioedema • changes in laboratory test results such as bleeding time and high blood sugar levels 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 EVAMIST include: • headache • breast pain • irregular vaginal bleeding or spotting • stomach or abdominal cramps, bloating • nausea and vomiting • hair loss • fluid retention • vaginal yeast infection Tell your healthcare provider if you have any side effects that bother you or do not go away. These are not all the possible side effects of EVAMIST. Call your doctor for medical advice about side effects. You may also report side effects to Padagis at 1-866-634-9120 or to FDA at 1-800-FDA-1088. What can I do to lower my chances of a serious side effect with EVAMIST? • Talk with your healthcare provider regularly about whether you should continue using EVAMIST. • 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 recommended for women 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 EVAMIST. • 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, weight, or if you use tobacco, you may have a higher chance of getting heart disease. Ask your healthcare provider for ways to lower your chances of getting heart disease. How should I store EVAMIST? • Store EVAMIST at room temperature 68°F to 77°F (20°C to 25°C ) • Do not freeze. • Safely throw away medicine that is out of date or no longer needed. Keep EVAMIST and all medicines out of the reach of children. General information about the safe and effective use of EVAMIST.

    Clinical Studies

    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 clinical practice. In a 12-week, randomized, placebo-controlled trial of Evamist in 454 women, 80 to 90 percent of women randomized to active drug received at least 70 days of therapy and 75 to 85 percent randomized to placebo received at least 70 days of therapy. The adverse reactions that occurred in at least 5 percent of women in any treatment group are shown in Table 1. Table 1.

    Geriatric Use

    8.5 Geriatric Use There have not been sufficient numbers of geriatric women involved in clinical studies utilizing Evamist to determine whether those over 65 years of age differ from younger subjects in their response to Evamist. The Women’s Health Initiative Studies 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

    8.4 Pediatric Use Evamist is not indicated for use in pediatric patients. Clinical studies have not been conducted in the pediatric population.

    Pregnancy

    8.1 Pregnancy Risk Summary Evamist is not indicated for use in pregnancy. There are no data with the use of Evamist in pregnant women; however, epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to combined hormonal contraceptives (estrogens and progestins) before conception or during early pregnancy. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

    Use In Specific Populations

    8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary Evamist is not indicated for use in pregnancy. There are no data with the use of Evamist in pregnant women; however, epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to combined hormonal contraceptives (estrogens and progestins) before conception or during early pregnancy. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. 8.2 Lactation Risk Summary Estrogens are present in human milk and can reduce milk production in breast-feeding females. 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 Evamist and any potential adverse effects on the breastfed child from Evamist or from the underlying maternal condition. 8.4 Pediatric Use Evamist is not indicated for use 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 Evamist to determine whether those over 65 years of age differ from younger subjects in their response to Evamist. The Women’s Health Initiative Studies 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

    WARNING: ENDOMETRIAL CANCER, CARDIOVASCULAR DISORDERS, PROBABLE DEMENTIA, BREAST CANCER, and UNINTENTIONAL SECONDARY EXPOSURE TO ESTROGEN 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 and random endometrial sampling when indicated, to rule out malignancy in all cases of 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 (14.2)] . The WHI Memory Study (WHIMS) estrogen-alone ancillary study of 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 (14.3)]. 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)]. 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 pulmonary embolism (PE), DVT, 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 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 (0.625mg) 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)] . Do not use estrogen plus progestogen therapy for the prevention of cardiovascular disease or dementia [see Warning and Precautions (5.1, 5.3), and Clinical Studies (14.2)] . Breast Cancer The WHI estrogen plus progestin substudy 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 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. Unintentional Secondary Exposure Breast budding and breast masses in prepubertal females and gynecomastia and breast masses in prepubertal males have been reported following unintentional secondary exposure to Evamist by women using this product. In most cases, the condition resolved with removal of Evamist exposure. Women should ensure that children do not come into contact with the site(s) where Evamist is applied. Healthcare providers should advise patients to strictly adhere to recommended instructions for use [ see Warnings and Precautions (5.4)] .
