Rosuvastatin Dosing for Hyperlipidemia
Start with rosuvastatin 10 mg once daily for most patients with hyperlipidemia, titrating to 20-40 mg daily for high-risk patients requiring high-intensity therapy to achieve LDL-C reductions ≥50%. 1, 2
Standard Dosing Regimen
The FDA-approved dosage range is 5-40 mg orally once daily, taken at any time of day with or without food. 2 The specific dose depends on cardiovascular risk stratification and LDL-C goals:
Primary Prevention (No Established ASCVD)
Moderate-intensity therapy: Rosuvastatin 5-10 mg daily for patients aged 40-75 years without ASCVD, targeting LDL-C reduction ≥30-49% and goal <70 mg/dL 1
High-intensity therapy: Rosuvastatin 20-40 mg daily for patients with additional ASCVD risk factors (including elevated hsCRP ≥2 mg/L), targeting LDL-C reduction ≥50% and goal <70 mg/dL 3, 1
Diabetes mellitus: Moderate-intensity statin (rosuvastatin 5-10 mg) is indicated for patients aged 40-75 years with diabetes for primary prevention 3
Secondary Prevention (Established ASCVD)
High-intensity therapy is recommended: Rosuvastatin 20-40 mg daily to achieve LDL-C reduction ≥50% and goal <55 mg/dL 1
If high-intensity therapy cannot be tolerated, use moderate-intensity therapy with ezetimibe added if LDL-C remains ≥70 mg/dL 3
Severe Hypercholesterolemia (LDL-C ≥190 mg/dL)
Maximally tolerated statin therapy is recommended for patients aged 20-75 years, typically starting with rosuvastatin 20-40 mg daily 3
Add ezetimibe if <50% LDL-C reduction achieved or LDL-C remains ≥100 mg/dL on maximally tolerated statin 3
Special Population Dosing Adjustments
Asian Patients
- Start at 5 mg once daily due to increased rosuvastatin plasma concentrations in this population 1, 2
- Consider risks and benefits when doses >20 mg daily are needed 2
Renal Impairment
- Mild to moderate impairment: No dosage adjustment needed 2
- Severe impairment (CrCl <30 mL/min/1.73 m²): Start at 5 mg daily and do not exceed 10 mg daily 1, 2
Pediatric Patients
- HeFH (ages 8-10 years): 5-10 mg once daily 2
- HeFH (ages ≥10 years): 5-20 mg once daily 2
- HoFH (ages ≥7 years): 20 mg once daily 2
Drug Interaction Dose Modifications
Critical dose limitations apply with specific concomitant medications: 2
- Do not exceed 5 mg daily: Cyclosporine, darolutamide 2
- Do not exceed 10 mg daily: Teriflunomide, enasidenib, capmatinib, regorafenib, gemfibrozil (if concomitant use unavoidable), atazanavir/ritonavir, lopinavir/ritonavir 2
- Do not exceed 20 mg daily: Fostamatinib, febuxostat, tafamidis (if concomitant use unavoidable) 2
- Avoid concomitant use: Gemfibrozil, tafamidis, multiple antiviral medications including sofosbuvir/velpatasvir/voxilaprevir 2
Monitoring and Titration
- Assess LDL-C as early as 4 weeks after initiation and adjust dosage accordingly 2
- The goal is to achieve target LDL-C levels based on risk category, with clinical trials demonstrating 52-63% LDL-C reduction at doses of 10-40 mg 4
- Rosuvastatin 10 mg achieves superior LDL-C reduction compared to atorvastatin 10 mg, simvastatin 10-40 mg, and pravastatin 10-40 mg 5, 6
Common Pitfalls to Avoid
Inadequate dose titration: Many high-risk patients require 20-40 mg daily to achieve LDL-C goals; starting at 10 mg and failing to uptitrate is a common error 1, 7
Ignoring drug interactions: Always review concomitant medications before prescribing, particularly cyclosporine, gemfibrozil, and antivirals which require significant dose restrictions 2
Antacid timing: When using aluminum/magnesium hydroxide antacids, administer rosuvastatin at least 2 hours before the antacid 2
Overlooking Asian ethnicity: Failure to start at 5 mg in Asian patients increases risk of adverse effects 2
Renal dosing errors: Patients with severe renal impairment should never exceed 10 mg daily 2
