Wording differs between labels, and the full indications section on this page takes precedence when it is present.

1 INDICATIONS AND USAGE DUAVEE is indicated in women with a uterus for: DUAVEE is a combination of conjugated estrogens with an estrogen agonist/antagonist indicated for treatment of the following conditions in women with a uterus: • Treatment of moderate to severe vasomotor symptoms associated with menopause ( 1.1 ) • Prevention of postmenopausal osteoporosis ( 1.2 ) Limitation of Use : DUAVEE should be used for the shortest duration consistent with treatment goals and risks for the individual woman ( 1.3 ) 1.1 Treatment of Moderate to Severe Vasomotor Symptoms Associated with Menopause 1.2 Prevention of Postmenopausal Osteoporosis 1.3 Important Limitations of Use • Use DUAVEE for the shortest duration consistent with treatment goals and risks for the individual woman. Postmenopausal women should be re-evaluated periodically as clinically appropriate to determine if treatment is still necessary. • When prescribing solely for the prevention of postmenopausal osteoporosis, therapy should only be considered for women at significant risk of osteoporosis and non-estrogen medication should be carefully considered.

2 DOSAGE AND ADMINISTRATION • Take one tablet orally once daily ( 2 ) 2.1 Treatment of Moderate to Severe Vasomotor Symptoms Associated with Menopause The recommended dosage is one DUAVEE tablet daily. 2.2 Prevention of Postmenopausal Osteoporosis The recommended dosage is one DUAVEE tablet daily. 2.3 General Dosing Information Take DUAVEE once daily, without regard to meals. Tablets should be swallowed whole. 2.4 Recommendations for Calcium and Vitamin D Supplementation Women taking DUAVEE for prevention of postmenopausal osteoporosis should add supplemental calcium and/or vitamin D to their diet if daily intake is inadequate. 2.5 Administration Instructions for Missed Doses If a dose of DUAVEE is missed, instruct patients to take it as soon as remembered unless it is almost time for the next scheduled dose. They should not take two doses at the same time. 2.6 Use in Patients with Renal Impairment The pharmacokinetics of DUAVEE have not been evaluated in patients with renal impairment. Use in patients with renal impairment is not recommended [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) ] . 2.7 Use in the Elderly DUAVEE has not been studied in women over 75 years of age. Use in women over 75 years of age is not recommended.

4 CONTRAINDICATIONS DUAVEE is contraindicated in women with any of the following conditions: • Undiagnosed abnormal uterine bleeding • Known, suspected, or past history of breast cancer • Known or suspected estrogen-dependent neoplasia • Active deep venous thrombosis, pulmonary embolism, or history of these conditions • Active arterial thromboembolic disease (for example, stroke, myocardial infarction) or history of these conditions • Hypersensitivity (for example, anaphylaxis, angioedema) to estrogens, bazedoxifene, or any ingredients • Known hepatic impairment or disease • Known protein C, protein S, or antithrombin deficiency or other known thrombophilic disorders • Pregnancy, as DUAVEE may cause fetal harm [see pregnancy (8.1) ] . • Undiagnosed abnormal uterine bleeding ( 4 , 5.3 ) • Known, suspected, or past history of breast cancer ( 4 , 5.3 ) • Known or suspected estrogen-dependent neoplasia ( 4 , 5.3 ) • Active or past history of venous thromboembolism ( 4 , 5.2 ) • Active or past history of arterial thromboembolism ( 4 , 5.2 ) • Hypersensitivity (angioedema, anaphylaxis) to estrogens, bazedoxifene, or any ingredients ( 4 ) • Known hepatic impairment or disease ( 4 , 5.9 , 8.7, 12.3 ) • Known protein C, protein S, or antithrombin deficiency or other known thrombophilic disorders ( 4 ) • Pregnancy ( 1 , 4 , 8.1 )

6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the label: • Cardiovascular Disorders [see Warnings and Precautions (5.2) ] • Malignant Neoplasms [see Warnings and Precautions (5.3) ] • Gallbladder Disease [see Warnings and Precautions (5.5) ] • Hypertriglyceridemia [see Warnings and Precautions (5.8) ] In four prospective, randomized, placebo-controlled trials the common adverse reactions (incidence ≥ 5%) were muscle spasms, nausea, diarrhea, dyspepsia, abdominal pain upper, oropharyngeal pain, dizziness, and neck pain ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Pfizer Inc. at 1-800-438-1985 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The safety of conjugated estrogens/bazedoxifene was evaluated in four Phase 3 clinical trials ranging from 12 weeks to 24 months in duration and enrolling 6,210 postmenopausal women age 40 to 75 years (mean age 55 years). A total of 1,224 patients were treated with DUAVEE and 1,069 patients received placebo. Women enrolled in Studies 1 and 2 received calcium (600–1200 mg) and vitamin D (200–400 IU) daily, while women in Studies 3 and 4 received no calcium and vitamin D supplementation as part of the protocol. The incidence of all-cause mortality was 0.0% in the DUAVEE group and 0.2% in the placebo group. The incidence of serious adverse reactions was 3.5% in the DUAVEE group and 4.8% in the placebo group. The percentage of patients who withdrew from treatment due to adverse reactions was 7.5% in the DUAVEE group and 10.0% in the placebo group. The most common adverse reactions leading to discontinuation were hot flush, abdominal pain upper, and nausea. The most commonly observed adverse reactions (incidence ≥ 5%) more frequently reported in women treated with DUAVEE than placebo are presented in Table 1. Table 1: Adverse Reactions (Incidence ≥ 5%) More Common in the DUAVEE Treatment Group in Placebo-controlled Trials DUAVEE (N=1224) n (%) Placebo (N=1069) n (%) Gastrointestinal disorders Nausea 100 (8) 58 (5) Diarrhea 96 (8) 57 (5) Dyspepsia 84 (7) 59 (6) Abdominal pain upper 81 (7) 58 (5) Musculoskeletal and connective tissue disorders Muscle spasms 110 (9) 63 (6) Neck pain 62 (5) 46 (4) Nervous system disorders Dizziness 65 (5) 37 (3) Respiratory, thoracic, and mediastinal disorders Oropharyngeal pain 80 (7) 61 (6) Venous thromboembolism : In the clinical studies with DUAVEE, the reporting rates for venous thromboembolism (deep venous thrombosis, pulmonary embolism, and retinal vein thrombosis) were low in all treatment groups. Adverse reactions of venous thromboembolism were reported in 0.0% of patients treated with DUAVEE and 0.1% of patients treated with placebo. Due to the low rate of events in both groups, it is not possible to conclude that the risk of venous thromboembolism with DUAVEE is different from that seen with other estrogen therapies [see Warnings and Precautions (5.2) ] .
