warnings and cautions
5 WARNINGS AND PRECAUTIONS Myopathy and Rhabdomyolysis: Risk factors include age 65 or greater, uncontrolled hypothyroidism, renal impairment, concomitant use with certain other drugs, and higher ZYPITAMAG dosage. Discontinue ZYPITAMAG if markedly elevated CK levels occur or myopathy is diagnosed or suspected. Temporarily discontinue ZYPITAMAG in patients experiencing an acute or serious condition at high risk of developing renal failure secondary to rhabdomyolysis. Inform patients of the risk of myopathy and rhabdomyolysis when starting or increasing the ZYPITAMAG dosage. Instruct patients to promptly report unexplained muscle pain, tenderness or weakness particularly if accompanied by malaise or fever ( 5.1 , 7 , 8.5 , 8.6 ). Immune-Mediated Necrotizing Myopathy (IMNM): Rare reports of IMNM, an autoimmune myopathy, have been reported. Discontinue ZYPITAMAG if IMNM is suspected. ( 5.2 ). Hepatic Dysfunction: Increases in serum transaminases have occurred, some persistent. Rare reports of fatal and non-fatal hepatic failure have occurred. Consider testing liver enzyme before initiating therapy and as clinically indicated thereafter. If serious hepatic injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs, promptly discontinue ZYPITAMAG. ( 5.3 ) 5.1 Myopathy and Rhabdomyolysis ZYPITAMAG may cause myopathy (muscle pain, tenderness, or weakness associated with elevated creatine kinase [CK]) and rhabdomyolysis. Acute kidney injury secondary to myoglobinuria and rare fatalities have occurred as a result of rhabdomyolysis in patients treated with statins, including pitavastatin. Risk Factors for Myopathy Risk factors for myopathy include age 65 years or greater, uncontrolled hypothyroidism, renal impairment, concomitant use of certain drugs (including other lipid-lowering therapies), and higher ZYPITAMAG dosage [see Dosage and Administration ( 2.2 ), Drug Interactions ( 7 ), and Use in Specific Populations ( 8.5 , 8.6 )] . Dosages of pitavastatin greater than 4 mg once daily were associated with an increased risk for severe myopathy in premarketing clinical studies. The maximum recommended dose of ZYPITAMAG is 4 mg once daily. Steps to Prevent or Reduce the Risk of Myopathy and Rhabdomyolysis ZYPITAMAG is contraindicated in patients taking cyclosporine and not recommended in patients taking gemfibrozil [see Contraindications ( 4 ) and Drug ...

adverse reactions
6 ADVERSE REACTIONS The following serious adverse reactions are discussed in other sections of the labeling: Myopathy and Rhabdomyolysis [see Warnings and Precautions ( 5.1 )]. Immune-Mediated Necrotizing Myopathy [see Warnings and Precautions ( 5.2 )] Hepatic Dysfunction [see Warnings and Precautions ( 5.3 )] Increases in HbA1c and Fasting Serum Glucose Levels [see Warnings and Precautions ( 5.4 )] . The most frequent adverse reactions (rate ≥ 2%) were myalgia, constipation, diarrhea, back pain, and pain in extremity. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Medicure at 1-800-509-0544 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Studies Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of one drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Adverse Reactions in Adults with Primary Hyperlipidemia In 10 controlled clinical studies and 4 subsequent open-label extension studies, 3,291 adult patients with primary hyperlipidemia were administered pitavastatin 1 mg to 4 mg daily. The mean continuous exposure of pitavastatin (1 mg to 4 mg) was 36.7 weeks (median 51.1 weeks). The mean age of the patients was 60.9 years (range; 18 years – 89 years) and 52% females. Approximately 93% of the patients were White 7% were Asian/Indian, 0.2% were African American and 0.3% were Hispanic and other. In controlled clinical studies and their open-label extensions, 3.9% (1 mg), 3.3% (2 mg), and 3.7% (4 mg) of pitavastatin-treated patients were discontinued due to adverse reactions. The most common adverse reactions that led to treatment discontinuation were: elevated creatine phosphokinase (0.6% on 4 mg) and myalgia (0.5% on 4 mg). Adverse reactions reported in ≥ 2% of patients in controlled clinical studies and at a rate greater than or equal to placebo are shown in Table 1. These studies had treatment duration of up to 12 weeks. Table 1.
