• Myopathy and Rhabdomyolysis : Risk factors include age 65 years or greater, uncontrolled hypothyroidism, renal impairment, and concomitant use with certain other drugs. Discontinue LESCOL XL if markedly elevated creatine kinase (CK) levels occur, or myopathy is diagnosed or suspected. Temporarily discontinue LESCOL XL 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 LESCOL XL dosage. Instruct patients to promptly report unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever. • Immune-Mediated Necrotizing Myopathy (IMNM) : Rare reports of IMNM, an autoimmune myopathy, have been reported with statin use. Discontinue LESCOL XL 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 LESCOL XL 5.1 Myopathy and Rhabdomyolysis LESCOL XL 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 with statins, including LESCOL XL. Myopathy, defined as muscle aching or muscle weakness in conjunction with increases in CK, values to greater than 10 times the upper limit of normal (ULN) was < 0.1% in fluvastatin clinical trials . Risk Factors for Myopathy Risk factors for myopathy include age 65 years or greater, uncontrolled hypothyroidism, renal impairment, and concomitant use with certain other drugs (including other lipid-lowering therapies) . Steps to Prevent or Reduce the Risk of Myopathy and Rhabdomyolysis Avoid concomitant use of LESCOL XL with gemfibrozil, cyclosporin, and fluconazole. When used concomitantly with LESCOL XL, lipid modifying doses (≥ 1 g/day) of niacin, fibrates, and colchicine may also increase the risk of myopathy and rhabdomyolysis . Discontinue LESCOL XL if markedly elevated CK levels occur or if myopathy is either diagnosed or suspected. Muscle symptoms and CK increases may resolve if LESCOL XL is discontinued. Temporarily discontinue LESCOL XL in patients experiencing an acute or serious condition at high risk of developing renal failure secondary to rhabdomyolysis, e.g., sepsis, shock, severe hypovolemia, major surgery, trauma, severe metabolic, endocrine, or electrolyte disorders, or uncontrolled epilepsy. Inform patients of the risk of myopathy and rhabdomyolysis when starting LESCOL XL. Instruct patients to promptly report any unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever

Immune-Mediated Necrotizing Myopathy There have been rare reports of immune-mediated necrotizing myopathy (IMNM), an autoimmune myopathy, associated with statin use, including reports of recurrence when the same or a different statin was administered. IMNM is characterized by proximal muscle weakness and elevated serum CK, which persist despite discontinuation of statin treatment; positive anti-HMG CoA reductase antibody, muscle biopsy showing necrotizing myopathy, and improvement with immunosuppressive agents. Additional neuromuscular and serologic testing may be necessary. Treatment with immunosuppressive agents may be required. Discontinue LESCOL XL if IMNM is suspected

Hepatic Dysfunction Increases in serum transaminases have been reported with use of LESCOL XL . In most cases, these changes appeared soon after initiation, were transient, were not accompanied by symptoms, and resolved or improved on continued therapy or after a brief interruption in therapy. Persistent increases to more than three times the ULN in serum transaminases have occurred in approximately 1.1% of patients receiving fluvastatin in clinical trials. Marked persistent increases of hepatic transaminases have also occurred with fluvastatin. There have been rare post-marketing reports of fatal and non-fatal hepatic failure in patients taking statins, including LESCOL XL. Patients who consume substantial quantities of alcohol and/or have a history of liver disease may be at increased risk for hepatic injury. Consider liver enzyme testing before LESCOL XL initiation and thereafter, when clinically indicated. LESCOL XL is contraindicated in patients with acute liver failure or decompensated cirrhosis . If serious hepatic injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs, promptly discontinue LESCOL XL

Increases in HbA1c and Fasting Serum Glucose Levels Increases in HbA1c and fasting serum glucose levels have been reported with statins, including LESCOL XL. Optimize lifestyle measures, including regular exercise, maintaining a healthy body weight, and making healthy food choices.

• Gemfibrozil : Avoid use with LESCOL XL. • Cyclosporine and Fluconazole : Avoid use with LESCOL XL. • Fibrates, Lipid-modifying doses (≥ 1 g/day) of Niacin, and Colchicine : Consider if the benefit of concomitant use with LESCOL XL outweighs the increased risk of myopathy and rhabdomyolysis. If concomitant use is decided, monitor patients for signs and symptoms of myopathy, particularly during initiation of therapy and during upward dose titration. • Warfarin : Obtain an International Normalized Ratio (INR) before starting and frequently enough after initiation or discontinuation to ensure that no significant alteration in INR occurs. Once the INR is stable, monitor INR at regular intervals. • Glyburide : Monitor blood glucose levels when LESCOL XL is initiated. • Phenytoin : Monitor plasma phenytoin levels when LESCOL XL treatment is initiated

Drug Interactions that Increase the Risk of Myopathy and Rhabdomyolysis with LESCOL XL Table 3 includes a list of drugs that increase the risk of myopathy and rhabdomyolysis when used concomitantly with fluvastatin and instructions for preventing or managing them . Table 3. Drug Interactions That Increase the Risk of Myopathy and Rhabdomyolysis with LESCOL XL Gemfibrozil Clinical impact There is an increased risk of myopathy/rhabdomyolysis when LESCOL XL is administered with gemfibrozil Intervention Avoid concomitant use of gemfibrozil with LESCOL XL. Cyclosporine Clinical impact Cyclosporine coadministration increases fluvastatin exposure. The risk of myopathy and rhabdomyolysis may be increased with concomitant use of cyclosporine with LESCOL XL. Intervention Avoid concomitant use of cyclosporine with LESCOL XL. Fluconazole Clinical impact Fluconazole coadministration increases fluvastatin exposure. The risk of myopathy and rhabdomyolysis may be increased with concomitant use of fluconazole with LESCOL XL. Intervention Avoid concomitant use of fluconazole with LESCOL XL Niacin Clinical impact Risk of myopathy and rhabdomyolysis may be enhanced with concomitant use with lipid-modifying doses (≥ 1 g/day) of niacin with LESCOL XL. Intervention Consider if the benefit of using lipid-modifying doses (≥ 1 g/day) of niacin concomitantly with LESCOL XL outweighs the increased risk of myopathy and rhabdomyolysis. If concomitant use is decided, monitor patients for signs and symptoms of myopathy, particularly during initiation of therapy and during upward dose titration. Fibrates Clinical impact Fibrates may cause myopathy when given alone. The risk of myopathy and rhabdomyolysis may be increased with concomitant use of fibrates with LESCOL XL. Intervention Consider if the benefit of using fibrates concomitantly with LESCOL XL outweighs the increased risk of myopathy and rhabdomyolysis. If concomitant use is decided, monitor patients for signs and symptoms of myopathy, particularly during initiation of therapy and during upward dose titration. Colchicine Clinical impact Cases of myopathy and rhabdomyolysis have been reported with concomitant use of colchicine with fluvastatin. Intervention Consider if the benefit of using colchicine concomitantly with LESCOL XL outweighs the increased risk of myopathy and rhabdomyolysis. If concomitant use is decided, monitor patients for signs and symptoms of myopathy, particularly during initiation of therapy and during upward dose titration
