Overdosage of Menostar
Information about signs, symptoms, and laboratory findings of acute ovedosage and the general principles of overdose treatment.10 OVERDOSAGE Overdosage of estrogen may cause nausea and vomiting, breast tenderness, abdominal pain, drowsiness and fatigue, and withdrawal bleeding in women. Treatment of overdose consists of discontinuation of Menostar therapy with institution of appropriate symptomatic care.
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, Warnings and Precautions ( 5.1 )] • Malignant Neoplasms [see Boxed Warning, Warnings and Precautions ( 5.2 )] The most common adverse reactions (≥ 10 percent) with Menostar are: upper respiratory tract infections, pain, arthralgia, and leukorrhea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Bayer HealthCare Pharmaceuticals Inc. at 1-888-84-BAYER (1-888-842-2937) 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. Menostar was investigated in a 2-year double blind, placebo-controlled, multicenter study in the United States. A total of 417 postmenopausal women (208 women on Menostar, 209 on placebo) 60 to 80 years old, with an intact uterus were enrolled in the study. At 24 months, 189 women remained in the Menostar group and 186 remained in the placebo group. Adverse events with an incidence of ≥5 percent in the Menostar 14 mcg group and greater than those reported in the placebo group are listed in Table 1.

Menostar 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 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 )
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, 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 follicle stimulating hormone (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 Menostar 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 The bioavailability of estradiol following application of a Menostar transdermal system, relative to that of a transdermal system delivering 25 mcg per day, was investigated in 18 healthy postmenopausal women, mean age 66 years (range 60 to 80 years). The mean serum estradiol concentrations upon administration of the two patches to the lower abdomen are shown in Figure 1. Transdermal administration of Menostar produced geometric mean serum concentration (C avg ) of estradiol of 13.7 pg/mL. No patches failed to adhere during the one week application period of both transdermal systems. Following application of the Menostar transdermal system to the abdomen, it is estimated to provide an average nominal in-vivo daily delivery of 14 mcg estradiol per day. The Menostar transdermal delivery system continuously releases estradiol which is transported across intact skin leading to sustained circulating levels of estradiol during a 7-day treatment period. The systemic availability of estradiol after transdermal administration is about 20 times higher than that after oral administration. This difference is due to the absence of first pass metabolism when estradiol is given by the transdermal route. Figure 1: Mean Uncorrected Serum 17ß-Estradiol Concentrations vs. Time Profile Following Application of the Menostar Transdermal System and the Climara® 6.5 cm2 Transdermal System Table 2 provides a summary of estradiol pharmacokinetic parameters determined during evaluation of the Menostar transdermal system using baseline uncorrected serum concentrations. Table 2: Summary of Estradiol Pharmacokinetic Parameters (Abdomen Application) Product Estradiol Daily Delivery Rate, mcg/day AUC (0-t last ) pg•h/mL C max pg/mL C avg pg/mL T max h C min pg/mL Menostar 14 2296 20.6 13.7 42 12.6 Climara 6.5 cm 2 25 4151 37.2 24.7 42 20.4 Pharmacokinetic parameters are expressed in geometric means except for the T max which represents the median estimate and the C min which is expressed as the arithmetic mean. The estimated estradiol daily delivery rate for Climara 6.5 cm 2 is quoted from the Climara labeling. 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 the blood largely bound to SHBG and albumin. In the clinical study with 208 patients on Menostar, SHBG concentration (mean ± SD) remained essentially unchanged over the 2 year period (baseline 45.1 ± 20.1 nmol/L, 24-month visit 46.4 ± 20.9 nmol/L). 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. Adhesion In a Menostar transdermal system pharmacokinetic study with 18 postmenopausal women, no patches failed to adhere during the one-week application period. Figure 1

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 progestogen to reduce the risk of endometrial cancer. Generally a woman without a uterus does not need to take 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. • Apply Menostar once-weekly to the lower abdomen. Do not apply Menostar to the breast. ( 2.1 ) 2.1 Prevention of Postmenopausal Osteoporosis Apply Menostar 14 mcg per day to a clean dry area of the lower abdomen once weekly. 2.2 Application of the Menostar Transdermal System Site Selection • Place the adhesive side of Menostar on a clean, dry area of the lower abdomen or the upper quadrant of the buttock. • Do not apply Menostar to or near the breasts. • Rotate the sites of application with an interval of at least 1-week allowed between applications to a same site. • Select an area that is not oily, damaged, or irritated. Avoid the waistline, since tight clothing may rub the transdermal system off. • Avoid application to areas where sitting would dislodge Menostar. Application • Apply Menostar immediately after opening the pouch and removing the protective liner. • Press Menostar firmly in place with the fingers for at least 10 seconds, making sure there is good contact, especially around the edges. • If the system lifts, apply pressure to maintain adhesion. • In the event that a system falls off, reapply it to a different location. If the old system cannot be reapplied, apply a new system for the remainder of the 7-day dosing interval. • Wear only one system at any one time during the 7-day dosing interval. • Swimming, bathing, or using a sauna while using Menostar has not been studied, and these activities may decrease the adhesion of the system and the delivery of estradiol. 2.3 Removal of the Menostar Transdermal System • Remove Menostar carefully and slowly to avoid irritation of the skin. • If any adhesive remains on the skin after removal of Menostar, 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.

Information necessary for patients to use the drug safely and effectively.Patient Package Insert Patient Information MENOSTAR (Mĕn-ō-stär) (estradiol transdermal system) Read this Patient Information before you start using MENOSTAR 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 MENOSTAR (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 MENOSTAR. 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 MENOSTAR will affect your chances of these conditions. You and your healthcare provider should talk regularly about whether you still need treatment with MENOSTAR. What is MENOSTAR? MENOSTAR is a prescription medicine patch (transdermal system) that contains estradiol (an estrogen hormone). What is MENOSTAR used for? MENOSTAR is used after menopause to: • 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 MENOSTAR 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 Menostar. Who should not use MENOSTAR? Do not start using MENOSTAR 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 MENOSTAR. • had a stroke or heart attack • currently have or have had blood clots • currently have or have had liver problems • are allergic to MENOSTAR or any of the ingredients in it. See the list of ingredients in MENOSTAR at the end of this leaflet. Before you use MENOSTAR, 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 MENOSTAR 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 MENOSTAR. • are pregnant or think you may be pregnant MENOSTAR is not for pregnant women. • are breastfeeding The hormone in MENOSTAR 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 MENOSTAR works. MENOSTAR 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 MENOSTAR? For detailed instructions, see the step-by-step instructions for using MENOSTAR at the end of this Patient Information. • Use MENOSTAR exactly as your healthcare provider tells you to use it. • MENOSTAR is for skin use only. • Change your MENOSTAR patch 1 time each week or every 7 days. • Apply your MENOSTAR 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 MENOSTAR 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 MENOSTAR to your breasts. • If you forget to apply a new MENOSTAR 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 MENOSTAR. How to Change MENOSTAR. • When changing MENOSTAR, peel off the used patch slowly from the skin. • After removal of MENOSTAR 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 MENOSTAR? 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 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 MENOSTAR. 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 MENOSTAR? • Talk with your healthcare provider regularly about whether you should continue using MENOSTAR. • If you have a uterus, talk with your healthcare provider about whether MENOSTAR 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 MENOSTAR. • 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 of getting heart disease. Ask your healthcare provider for ways to lower your chances of getting heart disease. How should I store and throw away used MENOSTAR? • Store MENOSTAR at room temperature 68°F to 77°F (20°C to 25°C). • Do not store MENOSTAR patches outside of their pouches. Apply immediately upon removal from the protective pouch. • Used patches still contain estrogen. To throw away the patch, fold the sticky side of the patch together, place it in a sturdy child-proof container, and place this container in the trash. Used patches should not be flushed in the toilet. Keep MENOSTAR and all medicines out of the reach of children. General information about the safe and effective use of MENOSTAR.

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 Bone Mineral Density in Postmenopausal Women The efficacy of Menostar in the prevention of postmenopausal osteoporosis was investigated in a 2-year double blind, placebo-controlled, multicenter study in the United States. A total of 417 postmenopausal women, 60 to 80 years of age, with an intact uterus were enrolled in the study. All participants received supplemental calcium and vitamin D. At the lumbar spine Menostar increased BMD by 2.3 percent after 1 year and 3 percent after 2 years compared with a 0.5 percent increase after 1 and 2 years of treatment with placebo. At the hip Menostar increased BMD by 0.9 percent after one year and 0.84 percent after two years compared with a mean decrease of 0.22 percent after 1 year and 0.71 percent after 2 years of placebo treatment. The changes in BMD from baseline were statistically significantly (p <0.001) greater during treatment with Menostar than during treatment with placebo for both the spine and hip after 1 and 2 years (Table 3). Table 3: Mean Percent BMD Change from Baseline in Lumbar Spine and Total Hip (Full Analysis Set) Lumbar spine Total hip Time points Menostar Na = 208 Placebo Na = 209 p-value Time points Menostar Na = 208 Placebo Na = 209 p-value nb = 189 nb = 186 nb = 189 nb =184 12-month Endpoint +2.29 +0.51 < 0.001 12-month Endpoint +0.90 -0.22 < 0.001 nb = 189 nb = 186 nb = 189 nb = 185 24-month Endpoint +2.99 +0.54 < 0.001 24-month Endpoint +0.84 -0.71 < 0.001 a) N = total number of patients. b) n = number of patients with data available for each variable. The BMD data of the study were analyzed according to baseline estradiol levels of the patients. Overall, estimated treatment effects on lumbar spine and total hip BMD after 2 years were approximately twice as large in the subgroup with baseline estradiol levels < 5 pg/mL than in the subgroup with baseline estradiol levels ≥ 5 pg/mL (Table 4).

For those outcomes included in the WHI "global index" that reached statistical significance, the absolute excess risks per 10,000 women-years in the group treated with CE-alone was 12 more strokes, while the absolute risk reduction per 10,000 women-years was 7 fewer hip fractures. 9 The absolute excess risk of events included in the "global index" was a non-significant 5 events per 10,000 women-years. 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. See Table 5. 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 increased the risk of ischemic stroke, and this excess risk was present in all subgroups of women examined. 10 See Table 5. 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, 6.5 percent Black, 5.4 percent Hispanic, 3.9 percent Other), are presented in Table 6.

Timing of initiation of estrogen plus progestin therapy relative to the start of menopause may affect the overall risk benefit profile. 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 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 )] .

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 A total of 417 postmenopausal women 61 to 79 years old, with an intact uterus, participated in the osteoporosis trial. More than 50 percent of women receiving study drug, were 65 years of age or older. Efficacy in older (≥ 65 years of age) and younger (<65 years of age) postmenopausal women in the osteoporosis treatment trial was comparable both at 12 and 24 months. Safety in older (≥ 65 years of age) and younger (<65 years of age) postmenopausal women in the osteoporosis treatment trial was also comparable throughout the study. 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
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 Menostar is not indicated for use 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 Menostar is not indicated for use in pregnancy. There are no data with the use of Menostar in pregnant women, however, epidemiologic studies and meta-analyses have not found an increased risk of genital or non-genital 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
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 Menostar is not indicated for use in pregnancy. There are no data with the use of Menostar in pregnant women, however, epidemiologic studies and meta-analyses have not found an increased risk of genital or non-genital 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 Menostar and any potential adverse effects on the breastfed child from Menostar or from the underlying maternal condition. 8.4 Pediatric Use Menostar is not indicated for use in pediatric patients. Clinical studies have not been conducted in the pediatric population. 8.5 Geriatric Use A total of 417 postmenopausal women 61 to 79 years old, with an intact uterus, participated in the osteoporosis trial. More than 50 percent of women receiving study drug, were 65 years of age or older. Efficacy in older (≥ 65 years of age) and younger (<65 years of age) postmenopausal women in the osteoporosis treatment trial was comparable both at 12 and 24 months. Safety in older (≥ 65 years of age) and younger (<65 years of age) postmenopausal women in the osteoporosis treatment trial was also comparable throughout the study. 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
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 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 ( 14.2 )] . 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 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 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 ( 14.3 )] . 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 ( 14.2 , 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 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.
