The following serious adverse reactions are discussed in greater detail in other sections of the label: Liver enzyme abnormalities [see Warnings And Precautions ( 5.2 )] Rhabdomyolysis and myopathy [see Warnings And Precautions ( 5.3 )] Common adverse reactions in clinical trials: o Ezetimibe administered alone (incidence ≥2% and greater than placebo): upper respiratory tract infection, diarrhea, arthralgia, sinusitis, pain in extremity, fatigue, and influenza ( 6.1 ) o Ezetimibe tablets coadministered with a statin (incidence ≥2% and greater than statin alone): nasopharyngitis, myalgia, upper respiratory tract infection, arthralgia, diarrhea, back pain, influenza, pain in extremity, and fatigue ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Marlex Pharmaceuticals, Inc. at 1-888-582-1953 or [email protected] or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in clinical practice. Monotherapy In 10 double-blind, placebo-controlled clinical trials, 2396 patients with primary hyperlipidemia (age range 9 to 86 years, 50% female, 90% White, 5% Black or African American, 2% Asians, 3% other races; 3% identified as Hispanic or Latino ethnicity) and elevated LDL-C were treated with ezetimibe 10 mg daily for a median treatment duration of 12 weeks (range 0 to 39 weeks). Adverse reactions reported in ≥2% of patients treated with ezetimibe and at an incidence greater than placebo in placebo-controlled studies of ezetimibere shown in Table 1 . Table 1. Adverse Reactions Occurring ≥2% and Greater than Placebo in Ezetimibe-treated Patients Adverse Reaction Placebo(%) n = 1,159 Ezetimibe 10 mg (%) n = 2,396 Upper respiratory tract infection 2.5 4.3 Diarrhea 3.7 4.1 Arthralgia 2.2 3.0 Sinusitis 2.2 2.8 Pain in extremity 2.5 2.7 Fatigue 1.5 2.4 Influenza 1.5 2.0 Combination with a Statin In 28 double-blind, controlled (placebo or active-controlled) clinical trials, 11,308 patients with primary hyperlipidemia (age range 10 to 93 years, 48% female, 85% White, 7% Black or African American, 3% Asians, 5% other races; 4% identified as Hispanic or Latino ethnicity) and elevated LDL-C were treated with ezetimibe 10 mg/day concurrently with or added to on-going statin therapy for a median treatment duration of 8 weeks (range 0 to 112 weeks). The incidence of consecutive increased transaminases (≥3 × ULN) was higher in patients receiving ezetimibe administered with statins (1.3%) than in patients treated with statins alone (0.4%). Adverse reactions reported in ≥2% of patients treated with ezetimibe + statin and at an incidence greater than statin are shown in Table 2 . Table 2: Adverse Reactions Occurring ≥2% in Ezetimibe-treated Patients Coadministered with a Statin and at an Incidence Greater than Statin Adverse Reaction All Statins (%) n = 9,361 Ezetimibe + All Statins (%) n = 11,308 Nasopharyngitis 3.3 3.7 Myalgia 2.7 3.2 Upper respiratory tract infection 2.8 2.9 Arthralgia 2.4 2.6 Diarrhea 2.2 2.5 Back pain 2.3 2.4 Influenza 2.1 2.2 Pain in extremity 1.9 2.1 Fatigue 1.6 2.0 *All Statins = all doses of all statins Combination with Fenofibrate This clinical trial involving 625 patients with mixed dyslipidemia (age range 20 to 76 years, 44% female, 79% White, 1% Black or African American, 20% other races; 11% identified as Hispanic or Latino ethnicity) treated for up to 12 weeks and 576 patients treated for up to an additional 48 weeks evaluated coadministration of ezetimibe and fenofibrate. Incidence rates for clinically important elevations (≥3 × ULN, consecutive) in hepatic transaminase levels were 4.5% and 2.7% for fenofibrate monotherapy (n=188) and ezetimibe coadministered with fenofibrate (n=183), respectively, adjusted for treatment exposure. Corresponding incidence rates for cholecystectomy were 0.6% and 1.7% for fenofibrate monotherapy and ezetimibe coadministered with fenofibrate, respectively [see Drug Interactions ( 7 )] . 6.2 Post-Marketing Experience Because the reactions below are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following additional adverse reactions have been identified during post-approval use of ezetimibe tablets: Blood Disorders : thrombocytopenia Gastrointestinal Disorders : abdominal pain; pancreatitis; nausea Hepatobiliary Disorders : elevations in liver transaminases; including elevations more than 5 X ULN;hepatitis; cholelithiasis; cholecystitis Immune System Disorders : Hypersensitivity reactions including: anaphylaxis, angioedema, rash, and urticaria Musculoskeletal Disorders : elevated creatine phosphokinase; myopathy/rhabdomyolysis Nervous System Disorders : dizziness; paresthesia; depression; headache Skin and Subcutaneous Tissue Disorders : erythema multiforme

Table 3 includes a list of drugs with clinically important drug interactions when administered concomitantly with Ezetimibe tablets and instructions for preventing or managing them. Table 3: Clinically Important Drug Interactions with Ezetimibe tablets Cyclosporine Clinical Impact: Concomitant use of ezetimibe and cyclosporine increases ezetimibe and cyclosporine concentrations. The degree of increase in ezetimibe exposure may be greater in patients with severe renal insufficiency [ see Clinical Pharmacology ( 12.3 )]. Intervention: Monitor cyclosporine concentrations in patients receiving ezetimibe and cyclosporine. In patients treated with cyclosporine, weigh the potential effects of the increased exposure to ezetimibe from concomitant use against the benefits of alterations in lipid levels provided by ezetimibe. Fibrates Clinical Impact: Both fenofibrate and ezetimibe may increase cholesterol excretion into the bile, leading to cholelithiasis. Co-administration of ezetimibe with fibrates other than fenofibrate is not recommended [ see Adverse Reactions ( 6.1 )]. Intervention: If cholelithiasis is suspected in a patient receiving ezetimibe and fenofibrate, gallbladder studies are indicated, and alternative lipid-lowering therapy should be considered. Bile Acid Sequestrants Clinical Impact: Concomitant cholestyramine administration decreased the mean exposure of total ezetimibe. This may result in a reduction of efficacy [see Clinical Pharmacology ( 12.3 )]. Intervention: In patients taking a bile acid sequestrant, administer ezetimibe at least 2 hours before or 4 hours after the bile acid sequestrant [see Dosage and Administration ( 2 )]. Cyclosporine: Combination increases exposure of ezetimibe and cyclosporine. Cyclosporine concentrations should be monitored in patients taking ezetimibe concomitantly. ( 7 ) Fibrates: Coadministration of ezetimibe with fibrates other than fenofibrate is not recommended until use in patients is adequately studied. If cholelithiasis is suspected in a patient receiving ezetimibe and fenofibrate, gallbladder studies are indicated, and alternative lipid-lowering therapy should be considered. ( 7 ) Bile Acid Sequestrants: Cholestyramine combination decreases exposure of ezetimibe. ( 7 ) See 17 for PATIENT COUNSELING INFORMATION and FDA-approved patient labeling. Revised: 03/2024
