As an adjunct to diet to reduce LDL-C in adults and pediatric patients 10 years of age and older with heterozygous familial hypercholesterolemia (HeFH) who require 80 mg of fluvastatin daily. Fluvastatin sodium extended-release tablets are indicated ( 1 ): To reduce the risk of undergoing coronary revascularization procedures and slow the progression of coronary atherosclerosis in adults with clinically evident coronary heart disease. As an adjunct to diet to reduce low-density lipoprotein cholesterol (LDL-C) in adults with primary hyperlipidemia. As an adjunct to diet to reduce LDL-C in adults and pediatric patients 10 years of age and older with heterozygous familial hypercholesterolemia (HeFH) who require 80 mg

2 DOSAGE AND ADMINISTRATION Fluvastatin sodium extended-release tablets can be taken with or without food and may be taken at any time of the day. (2.1) Do not break, crush or chew fluvastatin sodium extended-release tablets prior to administration. (2.1) Adults : The recommended starting dose is 80 mg (administered as one 80 mg fluvastatin sodium extended-release tablet once daily). (2.2) Children : The recommended dose is 80 mg once daily in pediatric patients 10 years of age and older who require 80 mg of fluvastatin. Fluvastatin sodium extended-release tablets are not recommended for dosage initiation in pediatric patients because the recommended starting dosage cannot be achieved with the available strength of 80 mg. (2.3) 2.1 Important Dosage Information Take fluvastatin sodium extended-release tablets orally once daily as a single dose, with or without food. Do not break, crush, or chew fluvastatin sodium extended-release tablets. Fluvastatin sodium extended-release tablet is only available as an 80 mg tablet. Fluvastatin sodium extended-release tablets cannot be titrated [see Dosage and Administration (2.2, 2.3)]. For patients that require a high-intensity statin or are unable to achieve their LDL-C goal receiving fluvastatin sodium extended-release tablets 80 mg daily, prescribe alternative LDL-C-lowering treatment. Assess LDL-C when clinically appropriate, as early as 4 weeks after initiating fluvastatin sodium extended-release tablets. 2.2 Recommended Dosage in Adult Patients The recommended dosage for fluvastatin sodium extended-release tablets is 80 mg once daily. 2.3 Recommended Dosage in Pediatric Patients Aged 10 Years of Age and Older with HeFH Fluvastatin sodium extended-release tablets are not recommended for dosage initiation in pediatric patients because the recommended starting dosage cannot be achieved with the available strength of 80 mg. Recommend use of another fluvastatin product to initiate dosing in pediatric patients. The recommended dosage of fluvastatin sodium extended-release tablets is 80 mg once daily in pediatric patients 10 years of age and older who require 80 mg of fluvastatin.

3 DOSAGE FORMS AND STRENGTHS Extended-release tablets: 80 mg of fluvastatin: yellow, round, slightly biconvex film-coated tablets, imprinted with “BS08” and “80” on one side, plain on the other side. Extended-release tablets: 80 mg of fluvastatin ( 3 )

4 CONTRAINDICATIONS Fluvastatin sodium extended-release tablets are contraindicated in patients with: Acute liver failure or decompensated cirrhosis [see Warnings and Precautions (5.3)]. Hypersensitivity to fluvastatin or any of the excipients in fluvastatin sodium extended-release tablets. Hypersensitivity reactions, including anaphylaxis, angioedema, and Stevens-Johnson syndrome have been reported [see Adverse Reactions (6.2)]. Acute liver failure or decompensated cirrhosis (4) Hypersensitivity to fluvastatin or any excipient in fluvastatin sodium extended-release tablets (4)

5 WARNINGS AND PRECAUTIONS Myopathy and Rhabdomyolysis: Risk factors include age 65 years or greater, uncontrolled hypothyroidism, renal impairment, and concomitant use with certain other drugs. Discontinue fluvastatin if markedly elevated creatine kinase (CK) levels occur, or myopathy is diagnosed or suspected. Temporarily discontinue fluvastatin 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 fluvastatin dosage. Instruct patients to promptly report unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever. (5.1) Immune-Mediated Necrotizing Myopathy (IMNM): Rare reports of IMNM, an autoimmune myopathy, have been reported with statin use. Discontinue fluvastatin 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 fluvastatin sodium extended-release tablets (5.3) 5.1 Myopathy and Rhabdomyolysis Fluvastatin 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 fluvastatin. 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 [see Adverse Reactions (6.1)]. 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) [see Drug Interactions (7.1)]. Steps to Prevent or Reduce the Risk of Myopathy and Rhabdomyolysis Avoid concomitant use of fluvastatin with gemfibrozil, cyclosporin, and fluconazole. When used concomitantly with fluvastatin, lipid modifying doses (≥ 1 g/day) of niacin, fibrates, and colchicine may also increase the risk of myopathy and rhabdomyolysis [see Drug Interactions (7.1)]. Discontinue fluvastatin if markedly elevated CK levels occur or if myopathy is either diagnosed or suspected. Muscle symptoms and CK increases may resolve if fluvastatin is discontinued. Temporarily discontinue fluvastatin 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 fluvastatin. Instruct patients to promptly report any unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever. 5.2 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 fluvastatin if IMNM is suspected. 5.3 Hepatic Dysfunction Increases in serum transaminases have been reported with use of fluvastatin [see Adverse Reactions (6.1)]. 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 fluvastatin. 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 fluvastatin initiation and thereafter, when clinically indicated. Fluvastatin sodium extended-release tablets are contraindicated in patients with acute liver failure or decompensated cirrhosis [see Contraindications (4)]. If serious hepatic injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs, promptly discontinue fluvastatin sodium extended-release tablets. 5.4 Increases in HbA1c and Fasting Serum Glucose Levels Increases in HbA1c and fasting serum glucose levels have been reported with statins, including fluvastatin. Optimize lifestyle measures, including regular exercise, maintaining a healthy body weight, and making healthy food choices.

6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the label: 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)] Most frequent adverse reactions occurring in ≥ 2.5% of subjects treated with fluvastatin sodium extended-release tablets and more than placebo are: influenza-like symptoms, sinusitis, dyspepsia, urinary tract infection, bronchitis, and nausea.

In the fluvastatin capsule, clinical trials there were 2,326 patients treated with fluvastatin (age range, 18 to 75 years, 44% women, 94% White, 4% Black or African American, 2% other ethnicities) with a median treatment duration of 24 weeks. The most common adverse reactions that led to treatment discontinuation and occurred at an incidence greater than placebo were: transaminase increased (0.8%), upper abdominal pain (0.3%), dyspepsia (0.3%), fatigue (0.2%), and diarrhea (0.2%). In the fluvastatin sodium extended-release tablets clinical trials there were 912 patients treated with fluvastatin sodium extended-release tablets (age range, 21 to 87 years, 52% women, 91% White, 4% Black of African American, 5% other ethnicities) with a median treatment duration of 24 weeks. The most common adverse reactions that led to treatment discontinuation were abdominal pain (0.7%), diarrhea (0.5%), nausea (0.4%), dyspepsia (0.4%) and chest pain (0.3%). Adverse reactions occurring in the fluvastatin capsules and fluvastatin sodium extended-release tablets controlled trials with a frequency 2% included the following: Table 1.

In the Fluvastatin Capsule Intervention Prevention Study (LIPS), the effect of fluvastatin capsules 40 mg, administered twice daily on the risk of recurrent cardiac events was assessed in 1,677 patients with coronary heart disease who had undergone a percutaneous coronary intervention. This was a multicenter, randomized, double-blind, placebo-controlled trial, patients were treated with dietary/lifestyle counseling and either fluvastatin capsules 40 mg (n = 844) or placebo (n = 833) given twice daily for a median of 3.9 years [see Clinical Studies (14.3)].

Fourteen of these patients (0.6%) were discontinued from therapy. In all clinical trials, a total of 33/2,969 patients (1.1%) had persistent transaminase elevations with an average fluvastatin exposure of approximately 71.2 weeks; 19 of these patients (0.6%) were discontinued. The majority of patients with these abnormal biochemical findings were asymptomatic. In a pooled analysis of all placebo-controlled studies in which fluvastatin capsules were used, persistent transaminase elevations (> 3 times the ULN on two consecutive weekly measurements) occurred in 0.2%, 1.5%, and 2.7% of patients treated with daily doses of 20, 40, and 80 mg (titrated to 40 mg twice daily) fluvastatin capsules, respectively. Ninety-one percent of the cases of persistent ALT/AST increased abnormalities (20 of 22 patients) occurred within 12 weeks of therapy and in all patients with persistent liver function test abnormalities there was an abnormal liver function test present at baseline or by Week 8. In the pooled analysis of 24-week controlled trials, persistent transaminase elevation occurred in 1.9%, 1.8%, and 4.9% of patients treated with fluvastatin sodium extended-release tablets 80 mg, fluvastatin capsules 40 mg and fluvastatin capsules 40 mg twice daily, respectively. In 13 of 16 patients treated with fluvastatin sodium extended-release tablets the abnormality occurred within 12 weeks of initiation of treatment with fluvastatin sodium extended-release tablets 80 mg. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of fluvastatin. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Musculoskeletal: Muscle cramps, myopathy, rhabdomyolysis, arthralgias, muscle spasms, muscle weakness, myositis. There have been rare reports of IMNM associated with statin use [see Warnings and Precautions (5.2)].

There have been rare postmarketing reports of cognitive impairment (e.g., memory loss, forgetfulness, amnesia, memory impairment, confusion) associated with the use of all statins. The reports are generally nonserious, and reversible upon statin discontinuation, with variable times to symptom onset (1 day to years) and symptom resolution (median of 3 weeks). There have been rare reports of new-onset or exacerbation of myasthenia gravis, including ocular myasthenia, and reports of recurrence when the same or a different statin was administered.
