DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS. In-vitro and in-vivo studies have shown that estrogens and progestins are metabolized partially by cytochrome P450 3A4 (CYP3A4). Therefore, inducers or inhibitors of CYP3A4 may affect estrogen and progestin drug metabolism. Inducers of CYP3A4 such as St. Johns wort (Hypericum perforatum) preparations, phenobarbital, carbamazepine, and rifampin may reduce plasma concentrations of estrogens and progestins, possibly resulting in 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 the estrogen or the progestin or both 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).

PEDIATRIC USE SECTION.

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

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics. Generally, serum estrogen concentration does not predict an individual womans therapeutic response to BIJUVA 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.

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. AbsorptionThe oral absorption of both estradiol and progesterone is subject to first-pass metabolism. After multiple doses of BIJUVA (estradiol and progesterone) capsules, mg/100 mg, the tmax (the time at which the maximum concentration is attained) for estradiol is approximately hours and approximately hours for progesterone (Figure 1, Figure 2, and Table 2, below). Steady state for both estradiol and progesterone components of BIJUVA, as well as estradiols main metabolite, estrone, is achieved within seven days.Figure 1: Mean Steady-State Serum Estradiol Concentrations Following Daily Oral Administration of mg Estradiol/100 mg Progesterone (Baseline Adjusted, at Day 7)Figure 2: Mean Steady-State Serum Progesterone Concentrations Following Daily Oral Administration of mg Estradiol/100 mg Progesterone (Baseline Adjusted, at Day 7)Table 2: Mean (SD) Steady-State Pharmacokinetic Parameters after Administration of Capsules Containing mg Estradiol/100 mg Progesterone in Healthy Postmenopausal Women (Baseline Adjusted, at Day 7) Dosage Strength (estradiol/progesterone)BIJUVA1 mg/100 mg Mean (SD)Effective 1/2 Calculated as 24oln(2)/ ln (accumulation ratio/(accumulation ratio-1)) for subjects with accumulation ratio >1.Abbreviations: AUC0- area under the concentration vs time curve within the dosing interval at steady-state, Cavg average concentration at steady-state, Cmax maximum concentration, SD standard deviation, tmax time to maximum concentration, 1/2 half-lifeEstradiolNAUC0- (pg.h/mL)20772.4 (384.1)Cmax (pg/mL)2042.27 (18.60)Cavg (pg/mL)1933.99 (14.53)tmax (h)194.93 (4.97)t 1/2 (h)1926.47 (14.61)EstroneAUC0- (pg.h/mL)204594 (2138)Cmax (pg/mL)20238.5 (100.4)Cavg (pg/mL)20192.1 (89.43)tmax (h)205.45 (3.47)t 1/2 (h)1922.37 (7.64)ProgesteroneAUC0- (ng.h/mL)2018.05 (15.58)Cmax (ng/mL)2011.31 (23.10)Cavg (ng/mL)200.76 (0.65)tmax (h)202.64 (1.51)t 1/2 (h)189.98 (2.57). Figure 1. Figure 2. Food EffectConcomitant food ingestion increased the AUC and Cmax of the progesterone component of BIJUVA relative to fasting state when administered at dose of 100 mg. In study where BIJUVA was administered to postmenopausal women at dose of mg estradiol/100 mg progesterone within 30 minutes of starting high-fat meal, the Cmax and AUC of progesterone were 162% and 79% higher, respectively, relative to the fasting state. Concomitant food ingestion had no effect on the AUC of the estradiol component of BIJUVA but decreased Cmax by approximately 54% and delayed tmax to 12 hours.. Distribution. EstradiolThe 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 circulating in the blood largely are bound to SHBG and albumin.. ProgesteroneProgesterone is approximately 96% to 99% bound to serum proteins, primarily to serum albumin (50% to 54%) and transcortin (43% to 48%).. EliminationFollowing repeat dosing with BIJUVA (estradiol and progesterone) capsules, mg/100 mg, the half-life of estradiol was approximately 26 hours. The half-life of progesterone, following repeat dosing was approximately 10 hours.. Metabolism. EstradiolExogenous estrogens are metabolized in the same manner as endogenous estrogens. Circulating estrogens exist in 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, the 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, significant portion of the circulating estrogens exist as sulfate conjugates, especially estrone sulfate, which serves as circulating reservoir for the formation of more active estrogens.. ProgesteroneProgesterone is metabolized primarily by the liver largely to pregnanediols and pregnanolones. Pregnanediols and pregnanolones are conjugated in the liver to glucuronide and sulfate metabolites. Progesterone metabolites, which are excreted in the bile, may be deconjugated and may be further metabolized in the intestine via reduction, dehydroxylation, and epimerization.. Excretion. EstradiolEstradiol, estrone, and estriol are excreted in the urine along with glucuronide and sulfate conjugates.. ProgesteroneThe glucuronide and sulfate conjugates of pregnanediol and pregnanolone are excreted in the bile and urine. Progesterone metabolites are eliminated mainly by the kidneys. Progesterone metabolites which are excreted in the bile may undergo enterohepatic recycling or may be excreted in the feces.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Long-term continuous administration of natural and synthetic estrogens in certain animal species increases the frequency of carcinomas of the breast, uterus, cervix, vagina, testis, and liver.Progesterone has not been tested for carcinogenicity in animals by the oral route of administration. When implanted into female mice, progesterone produced mammary carcinomas, ovarian granulosa cell tumors, and endometrial stromal sarcomas. In dogs, long-term intramuscular injections produced nodular hyperplasia and benign and malignant mammary tumors. Subcutaneous or intramuscular injections of progesterone decreased the latency period and increased the incidence of mammary tumors in rats previously treated with chemical carcinogen.Progesterone did not show evidence of genotoxicity in in vitro studies for point mutations or for chromosomal damage. In vivo studies for chromosome damage have yielded positive results in mice at oral doses of 1000 mg/kg and 2000 mg/kg. Exogenously administered progesterone has been shown to inhibit ovulation in number of species and it is expected that high doses given for an extended duration would impair fertility until the cessation of treatment.

CLINICAL PHARMACOLOGY SECTION.

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 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 negative feedback mechanism. Estrogens act to reduce the elevated levels of these hormones seen in postmenopausal women.Endogenous progesterone is secreted by the ovary, placenta, and adrenal gland. In the presence of adequate estrogen, progesterone transforms proliferative endometrium into secretory endometrium.Progesterone enhances cellular differentiation and generally opposes the actions of estrogens by decreasing estrogen receptor levels, increasing local metabolism of estrogens to less active metabolites, or inducing gene products that blunt cellular responses to estrogen. Progesterone exerts its effects in target cells by binding to specific progesterone receptors that interact with progesterone response elements in target genes. Progesterone receptors have been identified in the female reproductive tract, breast, pituitary, hypothalamus, and central nervous system.. 12.2 Pharmacodynamics. Generally, serum estrogen concentration does not predict an individual womans therapeutic response to BIJUVA 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. AbsorptionThe oral absorption of both estradiol and progesterone is subject to first-pass metabolism. After multiple doses of BIJUVA (estradiol and progesterone) capsules, mg/100 mg, the tmax (the time at which the maximum concentration is attained) for estradiol is approximately hours and approximately hours for progesterone (Figure 1, Figure 2, and Table 2, below). Steady state for both estradiol and progesterone components of BIJUVA, as well as estradiols main metabolite, estrone, is achieved within seven days.Figure 1: Mean Steady-State Serum Estradiol Concentrations Following Daily Oral Administration of mg Estradiol/100 mg Progesterone (Baseline Adjusted, at Day 7)Figure 2: Mean Steady-State Serum Progesterone Concentrations Following Daily Oral Administration of mg Estradiol/100 mg Progesterone (Baseline Adjusted, at Day 7)Table 2: Mean (SD) Steady-State Pharmacokinetic Parameters after Administration of Capsules Containing mg Estradiol/100 mg Progesterone in Healthy Postmenopausal Women (Baseline Adjusted, at Day 7) Dosage Strength (estradiol/progesterone)BIJUVA1 mg/100 mg Mean (SD)Effective 1/2 Calculated as 24oln(2)/ ln (accumulation ratio/(accumulation ratio-1)) for subjects with accumulation ratio >1.Abbreviations: AUC0- area under the concentration vs time curve within the dosing interval at steady-state, Cavg average concentration at steady-state, Cmax maximum concentration, SD standard deviation, tmax time to maximum concentration, 1/2 half-lifeEstradiolNAUC0- (pg.h/mL)20772.4 (384.1)Cmax (pg/mL)2042.27 (18.60)Cavg (pg/mL)1933.99 (14.53)tmax (h)194.93 (4.97)t 1/2 (h)1926.47 (14.61)EstroneAUC0- (pg.h/mL)204594 (2138)Cmax (pg/mL)20238.5 (100.4)Cavg (pg/mL)20192.1 (89.43)tmax (h)205.45 (3.47)t 1/2 (h)1922.37 (7.64)ProgesteroneAUC0- (ng.h/mL)2018.05 (15.58)Cmax (ng/mL)2011.31 (23.10)Cavg (ng/mL)200.76 (0.65)tmax (h)202.64 (1.51)t 1/2 (h)189.98 (2.57).

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. 14.1 Effects on Vasomotor Symptoms in Postmenopausal Women. The effectiveness and safety of BIJUVA (estradiol and progesterone) capsules, mg/100 mg, on moderate to severe vasomotor symptoms (hot flushes) due to menopause were examined in 12-week randomized, double-blind, placebo-controlled substudy of single 52-week safety study. total of 726 postmenopausal women were randomized to multiple dose combinations of estradiol and progesterone, and placebo; these women were 40 to 65 years of age (mean 54.6 years) and had at least 50 moderate to severe vasomotor symptoms per week at baseline. The mean number of years since last menstrual period was 5.9 years, with all women undergoing natural menopause. The primary efficacy population consisted of women who self-identified their race as: White (67%), Black/African American (31%), and Other (2.1%). In the substudy evaluating effects on moderate to severe vasomotor symptoms, total of 141 women received BIJUVA (estradiol and progesterone) capsules, mg/100 mg, and 135 women received placebo.The evaluated co-primary efficacy endpoints included: 1) mean weekly reduction in frequency of moderate to severe vasomotor symptoms with BIJUVA compared to placebo at Weeks and 12; clinically meaningful threshold for the reduction in frequency of vasomotor symptoms, defined as 14 vasomotor symptoms per week above placebo, was applied, and 2) mean weekly reduction in severity of moderate to severe vasomotor symptoms with BIJUVA compared to placebo at Weeks and 12.Overall, BIJUVA (estradiol and progesterone) capsules, mg/100 mg, statistically significantly reduced both the frequency and severity of moderate to severe vasomotor symptoms from baseline compared with placebo at Weeks and 12. clinically meaningful threshold of reduction of 14 vasomotor symptoms per week above placebo was not demonstrated for BIJUVA (estradiol and progesterone) capsules, mg/100 mg, until Week 5. The change from baseline in the frequency and severity of vasomotor symptoms observed and the difference from placebo are shown in Table and Table 4, respectively.Table 3: Mean Weekly Change from Baseline and Difference from Placebo in the Frequency of Moderate to Severe Vasomotor SymptomsBIJUVA1 mg/100 mg(N=141)Placebo(N=135)Least square mean difference (SE) from placeboP-value of least square mean difference from placebo using mixed model repeated measures analysesDefinitions: SD standard deviation; SE standard errorWeek 4n=134n=126Baseline72.1 (27.80)72.3 (23.44)Mean (SD) change from baseline-40.6 (30.59)-26.4 (27.05)Difference from placebo-12.81 (3.30)---P-value< 0.001---Week 12n=124n=115Baseline72.2 (25.04)72.2 (22.66)Mean (SD) change from baseline-55.1 (31.36)-40.2 (29.79)Difference from placebo-16.58 (3.44)---P-value<0.001---Table 4: Mean Weekly Change from Baseline and Difference from Placebo in the Severity of Moderate to Severe Vasomotor SymptomsBIJUVA1 mg/100 mg(N=141)Placebo(N=135)Least square mean difference (SE) from placebo P-value of least square mean difference from placebo using mixed model repeated measures analysesDefinitions: SD standard deviation; SE standard errorWeek 4n=134n=126Baseline2.54 (0.325)2.52 (0.249)Mean (SD) change from baseline-0.48 (0.547)-0.34 (0.386)Difference from placebo-0.13 (0.061)---P-value0.031---Week 12n=124n=115Baseline2.55 (0.235)2.52 (0.245)Mean (SD) change from baseline-1.12 (0.963)-0.56 (0.603)Difference from placebo-0.57 (0.100)---P-value<0.001---Adjusting for potential confounders such as BMI, smoking, alcohol use, and baseline estradiol level, treatment with BIJUVA (estradiol and progesterone) capsules, mg/100 mg, did not demonstrate statistically significant reductions in both frequency and severity of moderate to severe vasomotor symptoms by Week 12 in women who self-identified as Black/African Americans (data not shown).. 14.2 Effects on Endometrium in Postmenopausal Women. Effects of BIJUVA (estradiol and progesterone) capsules, mg/100 mg, on endometrial hyperplasia and endometrial malignancy were assessed in the 52-week safety trial. The Endometrial Safety population included women who had taken at least one dose of BIJUVA (estradiol and progesterone) capsules, mg/100 mg, and had baseline and post-baseline endometrial biopsies. During the trial, endometrial biopsy assessments revealed case of endometrial hyperplasia and no cases of endometrial cancer in women who received BIJUVA (estradiol and progesterone) mg/100 mg capsules, and no cases of hyperplasia or endometrial cancer in women who received placebo (see Table 5).Table 5: Incidence of Endometrial Hyperplasia After up to 12 Months of TreatmentBIJUVA1 mg/100 mg(N=281)Placebo(N=92)Hyperplasia incidence rate (n/N)1/281 (0.36)0/92 (0.00)One-sided upper 95% confidence limit1.973.93Four (4) cases of disordered proliferative endometrium were also reported for BIJUVA (estradiol and progesterone) capsules, mg/100 mg, in the 52-week safety trial.. 14.3 Effects on Uterine Bleeding or Spotting in Postmenopausal Women. Uterine bleeding or spotting was evaluated in the 52-week safety study by daily diary. At 52 weeks, cumulative amenorrhea was reported by 56.1% of women who received BIJUVA (estradiol and progesterone) capsules, mg/100 mg, and 78.9% who received placebo.. 14.4 Womens Health Initiative Studies. The WHI enrolled approximately 27,000 predominantly healthy postmenopausal women in two substudies to assess the risks and benefits of daily oral CE (0.625 mg)-alone or in combination with MPA (2.5 mg) compared to placebo in the prevention of certain chronic diseases. The primary endpoint was the incidence of CHD (defined as nonfatal MI, silent MI and CHD death), with invasive breast cancer as the primary adverse outcome. global index included the earliest occurrence of CHD, invasive breast cancer, stroke, PE, endometrial cancer (only in the CE plus MPA substudy), colorectal cancer, hip fracture, or death due to other causes. These substudies did not evaluate the effects of CE plus MPA or CE-alone on menopausal symptoms.WHI Estrogen Plus Progestin SubstudyThe 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 more CHD events, more strokes, 10 more PEs, and more invasive breast cancers, while the absolute risk reductions per 10,000 women-years were fewer colorectal cancers and 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% White, 6.8% Black, 5.4% Hispanic, 3.9% Other) are presented in Table 6.

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 distribution of stroke subtype or severity, including fatal strokes, in women receiving CE-alone compared to placebo. Estrogen-alone increased the risk for ischemic stroke, and this excess risk was present in all subgroups of women examined.10 Timing of the 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 50-59 years of age non-significant trend toward reduced risk for CHD [hazard ratio (HR) 0.63 (95% CI, 0.36 to 1.09)] and overall mortality [HR 0.71 (95% CI, 0.46 to 1.11)].. 14.5 Womens Health Initiative Memory Study. The WHIMS estrogen plus progestin ancillary study of WHI enrolled 4,532 predominantly healthy postmenopausal women 65 years of age and older (47% were 65 to 69 years of age; 35% were 70 to 74 years; 18% 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 years, the relative risk of probable dementia for CE plus MPA versus placebo was 2.05 (95% CI, 1.21 to 3.48). The absolute risk of probable dementia for CE plus MPA versus placebo was 45 versus 22 per 10,000 women-years. Probable dementia as defined in this study included Alzheimers 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-alone ancillary study of WHI enrolled 2,947 predominately healthy hysterectomized postmenopausal women 65 to 79 years of age and older (45% were 65 to 69 years of age; 36% were 70 to 74 years of age; 19% 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% CI, 0.83 to 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 this 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% CI, 1.19 to 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 SECTION.

8.5 Geriatric Use. There have not been sufficient numbers of geriatric women involved in clinical studies utilizing BIJUVA to determine whether those over 65 years of age differ from younger women in their response to BIJUVA.. The Womens Health Initiative StudiesIn the WHI estrogen plus progestin substudy (daily CE [0.625 mg] plus MPA [2.5 mg] versus placebo), there was higher relative risk of nonfatal stroke and invasive breast cancer in women greater than 65 years of age [see Clinical Studies (14.4)].In the WHI estrogen-alone substudy (daily CE [0.625 mg]-alone versus placebo), there was higher relative risk of stroke in women greater than 65 years of age [see Clinical Studies (14.4)].. The Womens Health Initiative Memory StudyIn 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 plus progestin or estrogen-alone when compared to placebo [see Warnings and Precautions (5.3), and Clinical Studies (14.5)].Since both ancillary studies were conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women8 [see Warnings and Precautions (5.3), and Clinical Studies (14.5)].

LABORATORY TESTS SECTION.

5.17 Laboratory Tests. Serum follicle stimulating hormone (FSH) and estradiol levels have not been shown to be useful in the management of moderate to severe vasomotor symptoms.

LACTATION SECTION.

8.2 Lactation. Risk SummaryEstrogens plus progestogens 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 mothers clinical need for BIJUVA and any potential adverse effects on the breastfed child from BIJUVA or from the underlying maternal condition.

MECHANISM OF ACTION SECTION.

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 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 negative feedback mechanism. Estrogens act to reduce the elevated levels of these hormones seen in postmenopausal women.Endogenous progesterone is secreted by the ovary, placenta, and adrenal gland. In the presence of adequate estrogen, progesterone transforms proliferative endometrium into secretory endometrium.Progesterone enhances cellular differentiation and generally opposes the actions of estrogens by decreasing estrogen receptor levels, increasing local metabolism of estrogens to less active metabolites, or inducing gene products that blunt cellular responses to estrogen. Progesterone exerts its effects in target cells by binding to specific progesterone receptors that interact with progesterone response elements in target genes. Progesterone receptors have been identified in the female reproductive tract, breast, pituitary, hypothalamus, and central nervous system.

NONCLINICAL TOXICOLOGY SECTION.

13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Long-term continuous administration of natural and synthetic estrogens in certain animal species increases the frequency of carcinomas of the breast, uterus, cervix, vagina, testis, and liver.Progesterone has not been tested for carcinogenicity in animals by the oral route of administration. When implanted into female mice, progesterone produced mammary carcinomas, ovarian granulosa cell tumors, and endometrial stromal sarcomas. In dogs, long-term intramuscular injections produced nodular hyperplasia and benign and malignant mammary tumors. Subcutaneous or intramuscular injections of progesterone decreased the latency period and increased the incidence of mammary tumors in rats previously treated with chemical carcinogen.Progesterone did not show evidence of genotoxicity in in vitro studies for point mutations or for chromosomal damage. In vivo studies for chromosome damage have yielded positive results in mice at oral doses of 1000 mg/kg and 2000 mg/kg. Exogenously administered progesterone has been shown to inhibit ovulation in number of species and it is expected that high doses given for an extended duration would impair fertility until the cessation of treatment.

OVERDOSAGE SECTION.

10 OVERDOSAGE. Overdosage of estrogen plus progestogen may cause nausea, vomiting, breast tenderness, abdominal pain, drowsiness and fatigue, and withdrawal bleeding may occur in women. Treatment of overdose consists of discontinuation of BIJUVA with institution of appropriate symptomatic care.

POSTMARKETING EXPERIENCE SECTION.

6.2 Postmarketing Experience. The following adverse reactions have been identified during post-approval use of BIJUVA. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.Gastrointestinal disordersAbdominal pain and discomfort, abdominal distention, diarrhea, nausea, vomiting.General disorders and administration site conditionsFatigue, feeling abnormal, malaise.InvestigationsWeight increased.Metabolism and nutrition disordersFluid retention.Musculoskeletal and connective tissue disordersMuscle spasms, pain in extremity.Nervous system disordersDizziness, headache, somnolence.Psychiatric disordersInsomnia, sleep disorder.Reproductive system and breast disordersBreast pain, breast tenderness, uterine bleeding.Skin and subcutaneous tissue disordersNight sweats, pruritus.Vascular disordersHot flush.

PREGNANCY SECTION.

8.1 Pregnancy. Risk SummaryBIJUVA is not indicated for use in pregnancy. There are no data with the use of BIJUVA 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 (estrogen 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.

Because other products and doses have not been studied in the same way, it is not known how the use of BIJUVA will affect your chances of these conditions. You and your healthcare provider should talk regularly about whether you still need treatment with BIJUVA.What is BIJUVABIJUVA is prescription medicine that contains two kinds of hormones, an estrogen and progestogen.What is BIJUVA used forBIJUVA is used after menopause to reduce moderate to severe hot flashes.Estrogens are hormones made by womans ovaries. The ovaries normally stop making estrogens when 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 take estrogens. In other women, symptoms can be more severe.Who should not use BIJUVADo not use BIJUVA if you have had your uterus (womb) removed (hysterectomy).BIJUVA contains progestogen to decrease the chance of getting cancer of the uterus. If you do not have uterus, you do not need progestogen and you should not use BIJUVA.Do not start using BIJUVA if you:have any unusual vaginal bleeding.Vaginal bleeding after menopause may be 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 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. If you have or have had cancer, talk with your healthcare provider about whether you should take BIJUVA.currently have or have had blood clots.had stroke or heart attack.currently have or have had liver problems.are allergic to BIJUVA or any of its ingredients. See the list of ingredients in BIJUVA at the end of this leaflet.Before you use BIJUVA, tell your healthcare provider about all of your medical conditions, including if you:have high levels of fat in your blood (triglycerides).have any unusual vaginal bleeding. Vaginal bleeding after menopause may be 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 BIJUVA. Your healthcare provider may need to check you more carefully if you have certain conditions, such as:asthma (wheezing)diabetesa genetic problem called porphyrialupushypertension (high blood pressure)have high calcium in your bloodepilepsy (seizures)migraineendometriosisangioedema (swelling of face or tongue)problems with your heart, liver, thyroid or kidneyso are going to have surgery or will be on bed rest. Your healthcare provider will let you know if you need to stop using BIJUVA.o are pregnant or think you may be pregnant. BIJUVA is not for pregnant women.o are breastfeeding. The hormones in BIJUVA 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 BIJUVA works. Some other medicines and food products may increase or decrease the concentrations of the hormones in BIJUVA in the blood. BIJUVA may affect how your other medicines work, and other medicines may affect how BIJUVA works. Keep list of your medicines and show it to your healthcare provider and pharmacist when you get new medicine.How should use BIJUVATake BIJUVA exactly as your healthcare provider tells you to take it.Take capsule by mouth each evening with food.If you miss dose of BIJUVA, take the missed dose as soon as possible with food, unless it is within two hours of the next evening dose of BIJUVA.Estrogens 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 to months) about whether you still need treatment with BIJUVA.What are the possible side effects of BIJUVASide 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 attackstrokeblood clotsbreast cancercancer of the lining of the uterus (womb)cancer of the ovarydementiagallbladder diseasehigh or low blood calcium levelschanges in visionhigh blood pressurehigh levels of fat in your blood (triglycerides)liver problemschanges in thyroid hormone levelsswelling or fluid retentioncancer changes of endometriosisenlargement of benign tumors of the uterus (fibroids)worsening swelling of face or tongue (angioedema) in women who have history of angioedemachanges 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 lumpsunusual vaginal bleedingchanges in vision or speechsudden new severe headachessevere pains in your chest or legs with or without shortness of breath, weakness and fatiguevomitingCommon side effects of BIJUVA include:breast tendernessheadachevaginal bleedingvaginal dischargepelvic painTell your healthcare provider if you have any side effect that bothers you or that does not go away.These are not all of the possible side effects of BIJUVA.

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS. 8.1 Pregnancy. Risk SummaryBIJUVA is not indicated for use in pregnancy. There are no data with the use of BIJUVA 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 (estrogen 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 SummaryEstrogens plus progestogens 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 mothers clinical need for BIJUVA and any potential adverse effects on the breastfed child from BIJUVA or from the underlying maternal condition.. 8.4 Pediatric Use. BIJUVA 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 BIJUVA to determine whether those over 65 years of age differ from younger women in their response to BIJUVA.. The Womens Health Initiative StudiesIn the WHI estrogen plus progestin substudy (daily CE [0.625 mg] plus MPA [2.5 mg] versus placebo), there was higher relative risk of nonfatal stroke and invasive breast cancer in women greater than 65 years of age [see Clinical Studies (14.4)].In the WHI estrogen-alone substudy (daily CE [0.625 mg]-alone versus placebo), there was higher relative risk of stroke in women greater than 65 years of age [see Clinical Studies (14.4)].. The Womens Health Initiative Memory StudyIn 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 plus progestin or estrogen-alone when compared to placebo [see Warnings and Precautions (5.3), and Clinical Studies (14.5)].Since both ancillary studies were conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women8 [see Warnings and Precautions (5.3), and Clinical Studies (14.5)].

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS. Estrogens increase the risk of gallbladder disease (5.4)Discontinue estrogen if severe hypercalcemia, loss of vision, severe hypertriglyceridemia, or cholestatic jaundice occurs (5.5, 5.6, 5.9, 5.10)Monitor thyroid function in women on thyroid replacement hormone therapy (5.11, 5.18). Estrogens increase the risk of gallbladder disease (5.4). Discontinue estrogen if severe hypercalcemia, loss of vision, severe hypertriglyceridemia, or cholestatic jaundice occurs (5.5, 5.6, 5.9, 5.10). Monitor thyroid function in women on thyroid replacement hormone therapy (5.11, 5.18). 5.1 Cardiovascular Disorders. Increased risks of PE, DVT, stroke, and MI are reported with estrogen plus progestin therapy. Increased risks of stroke and DVT are reported with estrogen-alone therapy. Immediately discontinue estrogen with or without progestogen therapy if any of these occur or are suspected.Manage appropriately any risk factors for arterial vascular disease (for example, hypertension, diabetes mellitus, tobacco use, hypercholesterolemia, and obesity) and/or venous thromboembolism (VTE) (for example, personal history or family history of VTE, obesity, and systemic lupus erythematosus).. StrokeThe WHI estrogen plus progestin substudy reported statistically significant increased risk of stroke in women 50 to 79 years of age receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women in the same age group receiving placebo (33 versus 25 strokes per 10,000 women-years, respectively) [see Clinical Studies (14.4)]. The increase in risk was demonstrated after the first year and persisted.1 Immediately discontinue estrogen with or without progestogen therapy if stroke occurs or is suspected.The WHI estrogen-alone substudy reported statistically significant increased risk of stroke in women 50 to 79 years of age receiving daily CE (0.625 mg)-alone compared to women in the same age group receiving placebo (45 versus 33 strokes per 10,000 women-years, respectively). The increase in risk was demonstrated in year and persisted [see Clinical Studies (14.4)]. Immediately discontinue estrogen-alone therapy if stroke occurs or is suspected.Subgroup analyses of women 50 to 59 years of age suggest no increased risk of stroke for those women receiving CE (0.625 mg)-alone versus those receiving placebo (18 versus 21 per 10,000 women-years).1 Coronary Heart DiseaseThe WHI estrogen plus progestin substudy reported an increased risk (not statistically significant) of coronary heart disease (CHD) events (defined as nonfatal MI, silent MI, or CHD death) in those women receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women receiving placebo (41 versus 34 per 10,000 women-years).1 An increase in relative risk was demonstrated in year 1, and trend toward decreasing relative risk was reported in years through [see Clinical Studies (14.4)].The WHI estrogen-alone substudy reported no overall effect on CHD events in women receiving estrogen-alone compared to placebo2 [see Clinical Studies (14.4)].Subgroup analysis of women 50 to 59 years of age, who were less than 10 years since menopause, suggests reduction (not statistically significant) of CHD events in those women receiving CE (0.625 mg)-alone compared to placebo (8 versus 16 per 10,000 women-years).1 In postmenopausal women with documented heart disease (n 2,763), average 66.7 years of age, in controlled clinical trial of secondary prevention of cardiovascular disease (Heart and Estrogen/Progestin Replacement Study; HERS), treatment with daily CE (0.625 mg) plus MPA (2.5 mg) demonstrated no cardiovascular benefit. During an average follow-up of 4.1 years, treatment with CE plus MPA did not reduce the overall rate of CHD events in postmenopausal women with established CHD. There were more CHD events in the CE plus MPA-treated group than in the placebo group in year 1, but not during the subsequent years. Two thousand three hundred and twenty-one (2,321) women from the original HERS trial agreed to participate in an open label extension of the original HERS, HERS II. Average follow-up in HERS II was an additional 2.7 years, for total of 6.8 years overall. Rates of CHD events were comparable among women in the CE plus MPA group and the placebo group in HERS, HERS II, and overall.. Venous ThromboembolismThe WHI estrogen plus progestin substudy reported statistically significant 2-fold greater rate of VTE (DVT and PE) in women receiving daily CE (0.625 mg) plus MPA (2.5 mg) compared to women receiving placebo (35 versus 17 per 10,000 women-years). Statistically significant increases in risk for both DVT (26 versus 13 per 10,000 women-years) and PE (18 versus per 10,000 women-years) were also demonstrated. The increase in VTE risk was demonstrated during the first year and persisted3 [see Clinical Studies (14.4)]. Immediately discontinue estrogen plus progestogen therapy if VTE occurs or is suspected.In the WHI estrogen-alone substudy, the risk of VTE was increased for women receiving daily CE (0.625 mg)-alone compared to placebo (30 versus 22 per 10,000 women-years), although only the increased risk of DVT reached statistical significance (23 versus 15 per 10,000 women-years). The increase in VTE risk was demonstrated during the first years4 [see Clinical Studies (14.4)]. Immediately discontinue estrogen-alone therapy if VTE occurs or is suspected.If feasible, discontinue estrogens at least to weeks before surgery of the type associated with an increased risk of thromboembolism, or during periods of prolonged immobilization.. 5.2 Malignant Neoplasm. Breast CancerAfter mean follow-up of 5.6 years, the WHI substudy of daily CE (0.625 mg) plus MPA (2.5 mg) reported an increased risk of invasive breast cancer in women who took daily CE plus MPA compared to placebo. In this substudy, prior use of estrogen-alone or estrogen plus progestin therapy was reported by 26% of the women. The relative risk of invasive breast cancer was 1.24, and the absolute risk was 41 versus 33 cases per 10,000 women-years, for CE plus MPA compared with placebo. Among women who reported prior use of hormone therapy, the relative risk of invasive breast cancer was 1.86, and the absolute risk was 46 versus 25 cases per 10,000 women-years, for CE plus MPA compared with placebo. Among women who reported no prior use of hormone therapy, the relative risk of invasive breast cancer was 1.09, and the absolute risk was 40 versus 36 cases per 10,000 women-years for CE plus MPA compared with placebo. In the same substudy, invasive breast cancers were larger, were more likely to be node positive, and were diagnosed at more advanced stage in the CE (0.625 mg) plus MPA (2.5 mg) group compared with the placebo group. Metastatic disease was rare, with no apparent difference between the two groups. Other prognostic factors, such as histologic subtype, grade and hormone receptor status did not differ between the groups5 [see Clinical Studies (14.4)].The WHI substudy of daily CE (0.625 mg)-alone provided information about breast cancer in estrogen-alone users. In the WHI estrogen-alone substudy, after an average follow-up of 7.1 years, daily CE-alone was not associated with an increased risk of invasive breast cancer [relative risk (RR) 0.80] compared to placebo6 [see Clinical Studies (14.4)].Consistent with the WHI clinical trial, observational studies have also reported an increased risk of breast cancer with estrogen plus progestin therapy, and smaller increase in the risk for breast cancer with estrogen-alone therapy, after several years of use. The risk increased with duration of use, and appeared to return to baseline over about years after stopping treatment (only the observational studies have substantial data on risk after stopping). Observational studies also suggest that the risk of breast cancer was greater, and became apparent earlier, with estrogen plus progestin therapy as compared to estrogen-alone therapy. These studies have not generally found significant variation in the risk of breast cancer among different estrogen plus progestin combinations, doses, or routes of administration.The use of estrogen-alone and estrogen plus progestin therapy has been reported to result in an increase in abnormal mammograms requiring further evaluation.In one-year trial, among 1684 women who received combination of estradiol plus progesterone (1 mg estradiol plus 100 mg progesterone or 0.5 mg estradiol plus 100 mg progesterone or 0.5 mg estradiol plus 50 mg progesterone or 0.25 mg estradiol plus 50 mg progesterone) or placebo (n=151), six new cases of breast cancer were diagnosed, two of which occurred among the group of 415 women treated with BIJUVA (estradiol and progesterone) capsules, mg/100 mg. No new cases of breast cancer were diagnosed in the group of 151 women treated with placebo.All women should receive yearly breast examinations by healthcare provider and perform monthly breast self-examinations. In addition, mammography examinations should be scheduled based on patient age, risk factors, and prior mammogram results.. Endometrial CancerEndometrial hyperplasia (a possible precursor of endometrial cancer) has been reported to occur at rate of approximately percent or less with BIJUVA (estradiol and progesterone) capsules, mg/100 mg.An increased risk of endometrial cancer has been reported with the use of unopposed estrogen therapy in woman with uterus. The reported endometrial cancer risk among unopposed estrogen users is about 2- to 12-fold greater than in non-users, and appears dependent on duration of treatment and on estrogen dose. Most studies show no significant increased risk associated with use of estrogens for less than year. The greatest risk appears associated with prolonged use, with an increased risk of 15- to 24-fold for to 10 years or more, and this risk has been shown to persist for at least to 15 years after estrogen therapy is discontinued.Clinical surveillance of all women using estrogen-alone or estrogen plus progestogen therapy is important. 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 with unknown etiology.There is no evidence that the use of natural estrogens results in different endometrial risk profile than synthetic estrogens of equivalent estrogen dose. Adding progestogen to estrogen therapy in postmenopausal women has been shown to reduce the risk of endometrial hyperplasia, which may be precursor to endometrial cancer.. Ovarian CancerThe CE plus MPA substudy of WHI reported that estrogen plus progestin increased the risk of ovarian cancer. After an average follow-up of 5.6 years, the relative risk for ovarian cancer for CE plus MPA versus placebo was 1.58 (95% confidence interval [CI], 0.77 to 3.24), but it was not statistically significant. The absolute risk for CE plus MPA versus placebo was versus cases per 10,000 women-years.7 meta-analysis of 17 prospective and 35 retrospective epidemiology studies found that women who used hormonal therapy for menopausal symptoms had an increased risk for ovarian cancer. The primary analysis, using case-control comparisons, included 12,110 cancer cases from the 17 prospective studies. The relative risks associated with current use of hormonal therapy was 1.41 (95% CI, 1.32 to 1.50); there was no difference in the risk estimates by duration of the exposure (less than years [median of years] vs. greater than years [median of 10 years] of use before the cancer diagnosis). The relative risk associated with combined current and recent use (discontinued use within years before cancer diagnosis) was 1.37 (95% CI, 1.27 to 1.48), and the elevated risk was significant for both estrogen-alone and estrogen plus progestin products. The exact duration of hormone therapy use associated with an increased risk of ovarian cancer, however, is unknown.. 5.3 Probable Dementia. In the WHI Memory Study (WHIMS) estrogen plus progestin ancillary study, population of 4,532 postmenopausal women 65 to 79 years of age was randomized to daily CE (0.625 mg) plus MPA (2.5 mg) or placebo. After an average follow-up of years, 40 women in the CE plus MPA group and 21 women in the placebo group were diagnosed with probable dementia. The relative risk of probable dementia for CE plus MPA versus placebo was 2.05 (95% CI, 1.21 to 3.48). The absolute risk of probable dementia for CE plus MPA versus placebo was 45 versus 22 cases per 10,000 women-years8 [see Use in Specific Populations (8.5), and Clinical Studies (14.5)].In the WHIMS estrogen-alone ancillary study, population of 2,947 hysterectomized women 65 to 79 years of age was randomized to daily CE (0.625 mg)-alone or placebo. After an average follow-up of 5.2 years, 28 women in the estrogen-alone group and 19 women in the placebo group were diagnosed with probable dementia. The relative risk of probable dementia for CE-alone versus placebo was 1.49 (95% CI, 0.83 to 2.66). The absolute risk of probable dementia for CE-alone versus placebo was 37 versus 25 cases per 10,000 women-years8 [see Use in Specific Populations (8.5), and Clinical Studies (14.5)].When data from the two populations in the WHIMS estrogen-alone and estrogen plus progestin ancillary studies were pooled as planned in the WHIMS protocol, the reported overall relative risk for probable dementia was 1.76 (95% CI, 1.19 to 2.60). Since both ancillary studies were conducted in women 65 to 79 years of age, it is unknown whether these findings apply to younger postmenopausal women8 [see Use in Specific Populations (8.5), and Clinical Studies (14.5)].. 5.4 Gallbladder Disease. 2- to 4-fold increase in the risk of gallbladder disease requiring surgery in postmenopausal women receiving estrogens has been reported.. 5.5 Hypercalcemia. Estrogen administration may lead to severe hypercalcemia in women with breast cancer and bone metastases. Discontinue estrogens, including BIJUVA if hypercalcemia occurs, and take appropriate measures to reduce the serum calcium level.. 5.6 Visual Abnormalities. Retinal vascular thrombosis has been reported in women receiving estrogens. Discontinue BIJUVA pending examination if there is sudden partial or complete loss of vision, or sudden onset of proptosis, diplopia, or migraine. Permanently discontinue estrogens, including BIJUVA, if examination reveals papilledema or retinal vascular lesions.. 5.7 Addition of Progestogen When Woman Has Not Had Hysterectomy. Studies of the addition of progestogen for 10 or more days of cycle of estrogen administration, or daily with estrogen in continuous regimen, have reported lowered incidence of endometrial hyperplasia than would be induced by estrogen treatment alone. Endometrial hyperplasia may be precursor to endometrial cancer.There are, however, possible risks that may be associated with the use of progestogens with estrogens compared to estrogen-alone regimens. These include an increased risk of breast cancer.. 5.8 Elevated Blood Pressure. In small number of case reports, substantial increases in blood pressure have been attributed to idiosyncratic reactions to estrogens. In large, randomized, placebo-controlled clinical trial, generalized effect of estrogens on blood pressure was not seen.. 5.9 Exacerbation of Hypertriglyceridemia. In women with pre-existing hypertriglyceridemia, estrogen therapy may be associated with elevations of plasma triglycerides leading to pancreatitis. Discontinue BIJUVA if pancreatitis occurs.. 5.10 Hepatic Impairment and/or Past History of Cholestatic Jaundice. Estrogens may be poorly metabolized in women with hepatic impairment. Exercise caution in any wormen with history of cholestatic jaundice associated with past estrogen use or with pregnancy. In the case of recurrence of cholestatic jaundice, discontinue BIJUVA.. 5.11 Exacerbation of Hypothyroidism. Estrogen administration leads to increased thyroid-binding globulin (TBG) levels. Women with normal thyroid function can compensate for the increased TBG by making more thyroid hormone, thus maintaining free T4 and T3 serum concentrations in the normal range. Women dependent on thyroid hormone replacement therapy who are also receiving estrogens may require increased doses of their thyroid replacement therapy. Monitor thyroid function in these women during treatment with BIJUVA to maintain their free thyroid hormone levels in an acceptable range.. 5.12 Fluid Retention. Estrogens and progestogens may cause some degree of fluid retention. Monitor any woman with condition(s) that might predispose her to fluid retention, such as cardiac or renal impairment. Discontinue estrogens plus progestogen therapy, including BIJUVA, with evidence of medically concerning fluid retention.. 5.13 Hypocalcemia. Estrogen-induced hypocalcemia may occur in women with hypoparathyroidism. Consider whether the benefits of estrogen therapy, including BIJUVA, outweigh the risks in such women.. 5.14 Exacerbation of Endometriosis. few cases of malignant transformation of residual endometrial implants have been reported in women treated post-hysterectomy with estrogen-alone therapy.. 5.15 Hereditary Angioedema. Exogenous estrogens may exacerbate symptoms of angioedema in women with hereditary angioedema. Consider whether the benefits of estrogen therapy, including BIJUVA, outweigh the risks in such women.. 5.16 Exacerbation of Other Conditions. Estrogen therapy, including BIJUVA, may cause an exacerbation of asthma, diabetes mellitus, epilepsy, migraine, porphyria, systemic lupus erythematosus, and hepatic hemangiomas. Consider whether the benefits of estrogen therapy outweigh the risks in such women.. 5.17 Laboratory Tests. Serum follicle stimulating hormone (FSH) and estradiol levels have not been shown to be useful in the management of moderate to severe vasomotor symptoms.. 5.18 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 antifactor 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 as measured by protein-bound iodine (PBI), T4 levels (by column or by radioimmunoassay) or T3 levels by radioimmunoassay. T3 resin uptake is decreased, reflecting the elevated TBG. Free T4 and free T3 concentrations are unaltered. Women on thyroid replacement therapy may require higher doses of thyroid hormone.Other binding proteins may be elevated in serum, for example, corticosteroid binding globulin (CBG), sex hormone-binding globulin (SHBG), leading to increased total circulating corticosteroids and sex steroids, respectively. Free hormone concentrations, such as testosterone and estradiol, may be decreased. Other plasma proteins may be increased (angiotensinogen/renin substrate, alpha-1-antitrypsin, ceruloplasmin).Increased plasma high-density lipoprotein (HDL) and HDL2 cholesterol subfraction concentrations, reduced low-density lipoprotein (LDL) cholesterol concentrations, increased triglyceride levels.Impaired glucose tolerance..
