Important Safety Information

Indications and Usage

  • As an adjunct to diet in patients with primary non-familial hyperlipidemia to reduce low-density lipoprotein cholesterol (LDL-C).

  • Alone or as an adjunct to other LDL-C-lowering therapies in patients with homozygous familial hypercholesterolemia (HoFH) to reduce LDL-C.

Important Safety Information

Contraindications: ROSZET is contraindicated in patients with active liver disease or decompensated cirrhosis, and hypersensitivity to any component of this product.
Myopathy and Rhabdomyolysis: ROSZET may cause myopathy (muscle pain, tenderness, or weakness with creatine kinase [CK] above ten times the upper limit of normal) and rhabdomyolysis. Acute kidney injury secondary to myoglobinuria and rare fatalities have occurred as a result of rhabdomyolysis with statins, including rosuvastatin.

Risk factors for myopathy include age 65 years or greater, uncontrolled hypothyroidism, renal impairment, concomitant use with certain other drugs including other lipid-lowering therapies, and higher ROSZET dosage; Asian patients on ROSZET may be at higher risk for myopathy. The myopathy risk is greater in patients taking ROSZET 40 mg/10 mg daily compared with lower ROSZET dosages.
The concomitant use of ROSZET with cyclosporine or gemfibrozil is not recommended. ROSZET dosage modifications are recommended for patients taking certain anti-viral medications, darolutamide, and regorafenib. Niacin, fibrates, and colchicine may also increase the risk of myopathy and rhabdomyolysis.
Discontinue ROSZET if markedly elevated CK levels occur or myopathy is diagnosed or suspected. Muscle symptoms and CK increases may resolve if ROSZET is discontinued. 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. IMNM is characterized by: proximal muscle weakness and elevated serum creatine kinase, which persist despite discontinuation of statin treatment; positive anti-HMG CoA reductase antibody; muscle biopsy showing necrotizing myopathy; and improvement with immunosuppressive agents. Treatment with immunosuppressive agents may be required. Consider risk of IMNM carefully prior to initiation of a different statin. If therapy is initiated with a different statin, monitor for signs and symptoms of IMNM.

Hepatic Dysfunction: Increases in serum transaminases have occurred with rosuvastatin. Consider liver enzyme testing before ROSZET initiation and thereafter, when clinically indicated. There have been rare post marketing reports of fatal and non-fatal hepatic failure in patients taking statins, including rosuvastatin. Patients who consume substantial quantities of alcohol and/or have a history of liver disease may be at increased risk for hepatic injury. If serious hepatic injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs, promptly discontinue ROSZET.

Proteinuria and Hematuria: Dipstick-positive proteinuria and microscopic hematuria were observed among rosuvastatin treated patients. These findings were more frequent in patients taking rosuvastatin 40 mg, when compared to lower doses of rosuvastatin or comparator statins, though it was generally transient and was not associated with worsening renal function. Although the clinical significance of this finding is unknown, consider a dose reduction for patients on ROSZET therapy with unexplained persistent proteinuria and/or hematuria during routine urinalysis testing.

HbA1c and Fasting Serum Glucose: Increases in HbA1c and fasting serum glucose levels have been reported with statins, including rosuvastatin. Based on clinical trial data with rosuvastatin, in some instances these increases may exceed the threshold for the diagnosis of diabetes mellitus.

Adverse Reactions: Most frequent adverse reactions (incidence >2% and greater than placebo) for rosuvastatin in clinical trials are: headache, nausea, myalgia, asthenia, dizziness, asthenia, constipation, and abdominal pain. Other adverse reactions reported in clinical studies were hypersensitivity (including rash, pruritus, urticaria, and angioedema), and pancreatitis. For ezetimibe co-administered with a statin most frequent adverse reactions (incidence >2% and greater than statin alone) are nasopharyngitis, myalgia, upper respiratory tract infection, arthralgia, diarrhea, back pain, influenza, pain in extremity, and fatigue. For ezetimibe monotherapy most frequent adverse reactions (incidence >2% and greater than placebo) are upper respiratory tract infection, diarrhea, arthralgia, sinusitis, pain in extremity, fatigue and influenza.
There have been rare post marketing reports of cognitive impairment (e.g., memory loss, forgetfulness, amnesia, memory impairment, confusion) associated with statin use, including ROSZET. These cognitive issues have been reported for all statins. The reports are generally nonserious, and reversible upon statin discontinuation.

Drug Interactions:
Gemfibrozil or Cyclosporin: Avoid concomitant use with ROSZET.
Antivirals: Avoid concomitant use or adjust dose of ROSZET.
Darolutamide: Do not exceed ROSZET 5 mg/10 mg once daily.
Regorafenib: Do not exceed ROSZET 10 mg/10 mg once daily.
Fenofibrates, Niacin, Colchicine: Consider risks and benefits of concomitant use with ROSZET.

Warfarin: Obtain INR before ROSZET initiation and monitor INR during ROSZET initiation or dosage adjustment.

Use in Specific Populations: Discontinue ROSZET when pregnancy is recognized as it may cause fetal harm. Breastfeeding is not recommended during treatment with ROSZET.
