The dosage range is 10 mg-10 mg to 10 mg-40 mg per day. Initiation of therapy with 10 mg-10 mg per day may be considered for patients requiring less aggressive LDL-C reductions. Patients who require a larger reduction in LDL-C (greater than 55%) may be started at 10 mg-40 mg per day in the absence of moderate to severe renal impairment (estimated glomerular filtration rate less than 60 mL/min/1.73 m2). After initiation or titration, lipid levels may be analyzed after 2 or more weeks and dosage adjusted, if needed.
Due to the increased risk of myopathy, including rhabdomyolysis, particularly during the first year of

Patients should be placed on a standard cholesterol-lowering diet before receiving ezetimibe-simvastatin and should continue on this diet during treatment with ezetimibe-simvastatin. The dosage should be individualized according to the baseline LDL-C level, the recommended goal of therapy, and patient response.
As an adjunct to diet to reduce elevated total cholesterol (total-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (Apo B), triglycerides (TG), and non-high-density lipoprotein cholesterol (non-HDL-C), and to increase high-density lipoprotein cholesterol (HDL-C) in patients with primary (heterozygous familial and nonfamilial) hyperlipidemia or mixed hyperlipidemia.
