What is the recommended dose of fenofibrate for an adult patient with hypertriglyceridemia?

Recommended Fenofibrate Dosing for Hypertriglyceridemia

For adults with hypertriglyceridemia, initiate fenofibrate at 54-160 mg once daily with meals, with the specific dose determined by triglyceride severity and renal function. 1, 2

Dosing Algorithm by Triglyceride Level

Severe to Very Severe Hypertriglyceridemia (≥500 mg/dL)

• Start fenofibrate 54-160 mg once daily immediately to prevent acute pancreatitis, regardless of LDL-C levels or cardiovascular risk 1, 2
• The FDA-approved dosing range is 54-160 mg once daily, with 160 mg as the maximum dose 2
• This represents first-line therapy before addressing LDL cholesterol, as statins provide only 10-30% triglyceride reduction—insufficient for pancreatitis prevention at this level 1
• Fenofibrate reduces triglycerides by 30-50% 1, 3

Moderate Hypertriglyceridemia (200-499 mg/dL)

• Consider fenofibrate 54-160 mg once daily if triglycerides remain elevated after 3 months of optimized lifestyle modifications and statin therapy 1
• Statins should be first-line pharmacologic therapy if the patient has elevated LDL-C or 10-year ASCVD risk ≥7.5%, as they provide proven cardiovascular benefit 1
• Fenofibrate is appropriate as add-on therapy or as monotherapy in patients with isolated hypertriglyceridemia and low HDL cholesterol 1, 3

Mild Hypertriglyceridemia (150-199 mg/dL)

• Fenofibrate is generally not indicated at this level unless other specific circumstances exist 1
• Focus on lifestyle modifications and statin therapy if cardiovascular risk warrants treatment 1

Critical Dose Adjustments Based on Renal Function

Renal function determines the maximum safe fenofibrate dose and is the most important safety consideration. 1, 3, 2

Normal Renal Function (eGFR ≥60 mL/min/1.73 m²)

• Start fenofibrate 54 mg daily, with option to titrate up to 160 mg daily based on response at 4-8 week intervals 1
• The FDA label indicates 160 mg once daily as the initial dose for primary hypercholesterolemia or mixed dyslipidemia 2

Mild to Moderate Renal Impairment (eGFR 30-59 mL/min/1.73 m²)

• Start fenofibrate 54 mg daily and do NOT exceed this dose 1, 3, 2
• Monitor renal function within 3 months after initiation and every 6 months thereafter 1

Severe Renal Impairment (eGFR <30 mL/min/1.73 m²)

• Fenofibrate is contraindicated, including in dialysis patients 2
• If eGFR persistently decreases to <30 mL/min/1.73 m² during treatment, discontinue fenofibrate immediately 1

Administration and Monitoring

Timing and Administration

• Take fenofibrate with meals to optimize absorption 2
• When combining with statins, take fenofibrate in the morning and statins in the evening to minimize peak dose concentrations 1

Essential Monitoring Parameters

• Baseline assessment: Obtain serum creatinine, eGFR, liver function tests (AST, ALT, total bilirubin), creatine kinase, and lipid panel 1, 2
• Follow-up monitoring:
  • Recheck lipid panel in 4-8 weeks after initiation or dose adjustment 1
  • Monitor renal function within 3 months after initiation and every 6 months thereafter 1
  • Monitor liver function periodically for the duration of therapy 2
  • Check creatine kinase if muscle symptoms develop 1

Safety Considerations for Combination Therapy

When Combining Fenofibrate with Statins

• Use lower statin doses (e.g., atorvastatin 10-20 mg maximum) to minimize myopathy risk, particularly in patients >65 years or with renal disease 1, 3
• Use fenofibrate, NOT gemfibrozil, as fenofibrate has a significantly better safety profile when combined with statins because it does not inhibit statin glucuronidation 1, 3
• Monitor for muscle symptoms and obtain baseline and follow-up creatine kinase levels 1, 3

Contraindications

• Severe renal dysfunction (eGFR <30 mL/min/1.73 m²), including dialysis patients 2
• Active liver disease 2
• Gallbladder disease 2
• Known hypersensitivity to fenofibrate 2
• Nursing mothers 2

Common Pitfalls to Avoid

• Do NOT start with statin monotherapy when triglycerides are ≥500 mg/dL—fibrates must be initiated first to prevent pancreatitis 1
• Do NOT ignore renal function—failure to adjust dose based on eGFR can lead to serious adverse events including rhabdomyolysis 1, 3, 2
• Do NOT combine fenofibrate with gemfibrozil—this combination has significantly higher myopathy risk 1
• Do NOT discontinue statins in favor of fibrate monotherapy in patients with cardiovascular risk, as statins provide proven mortality benefit through LDL-C reduction 1

Expected Outcomes and Treatment Goals

• Primary goal for severe hypertriglyceridemia: Rapid reduction to <500 mg/dL to eliminate pancreatitis risk 1
• Secondary goal: Further reduction to <200 mg/dL (ideally <150 mg/dL) to reduce cardiovascular risk 1
• Tertiary goal: Non-HDL-C <130 mg/dL once triglycerides are controlled 1
• Fenofibrate typically reduces triglycerides by 30-50% 1, 3, 4, 5
