Recommended Fenofibrate Dosing for Hypertriglyceridemia
For adults with hypertriglyceridemia, fenofibrate should be initiated 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 Hypertriglyceridemia (≥500 mg/dL)
- Initiate fenofibrate 54-160 mg once daily immediately to prevent acute pancreatitis, regardless of LDL-C levels or cardiovascular risk 1, 2
- This triglyceride threshold carries a 14% risk of acute pancreatitis and requires urgent pharmacologic intervention 1, 3
- The FDA-approved dosing range for severe hypertriglyceridemia is 54-160 mg once daily, with 160 mg as the maximum dose 2
Moderate Hypertriglyceridemia (200-499 mg/dL)
- Consider fenofibrate 54-160 mg once daily if triglycerides remain elevated after 3 months of optimized lifestyle modifications, particularly in patients with low HDL-C or additional cardiovascular risk factors 1
- Statins should generally be prioritized first in this range if LDL-C is elevated or 10-year ASCVD risk is ≥7.5%, as they provide proven cardiovascular benefit 1, 3
- Fenofibrate provides 30-50% triglyceride reduction in this population 1, 3
Mild Hypertriglyceridemia (150-199 mg/dL)
- Lifestyle modifications are first-line, with fenofibrate reserved for cases where statins are contraindicated or when triglycerides remain elevated despite statin therapy 3
- This range does not meet the threshold for immediate pharmacologic intervention with fibrates 3
Critical Renal Dose Adjustments
Renal function assessment is mandatory before initiating fenofibrate and must be monitored throughout therapy. 1, 4, 2
Dosing by eGFR:
- eGFR ≥60 mL/min/1.73 m²: Start at 54 mg daily, may titrate up to 160 mg daily based on response 4
- eGFR 30-59 mL/min/1.73 m²: Initial dose 54 mg daily; do NOT exceed 54 mg/day 1, 4, 2
- eGFR <30 mL/min/1.73 m²: Fenofibrate is contraindicated (severe renal impairment) 1, 4, 2
- Dialysis patients: Fenofibrate is contraindicated 2
Monitoring Requirements:
- Check renal function (creatinine, eGFR) before initiation 1, 4
- Recheck within 3 months after initiation 1, 4
- Monitor every 6 months thereafter during chronic therapy 1, 4
- Discontinue immediately if eGFR persistently decreases to <30 mL/min/1.73 m² during follow-up 1, 4
Administration Guidelines
- Take fenofibrate with meals to optimize absorption 2
- Dosing is once daily, typically in the morning 4
- If combining with statins in the future, take fenofibrate in the morning and statins in the evening to minimize peak dose concentrations 4
Safety Considerations When Combining with Statins
If combination therapy with statins becomes necessary, fenofibrate has a significantly better safety profile than gemfibrozil. 1, 4
- Use lower statin doses (e.g., atorvastatin 10-20 mg maximum) to minimize myopathy risk 1, 4
- Monitor for muscle symptoms and obtain baseline and follow-up creatine kinase (CPK) levels 1, 3
- Risk is particularly elevated in patients >65 years, those with diabetes, renal disease, or hypothyroidism 1, 4
- Never combine fenofibrate with gemfibrozil due to dramatically increased rhabdomyolysis risk 1
Common Pitfalls to Avoid
- Do NOT use fenofibrate as first-line therapy for moderate hypertriglyceridemia when statins are indicated, as statins provide proven cardiovascular benefit while fenofibrate monotherapy does not 4
- Do NOT delay fenofibrate initiation while attempting lifestyle modifications alone in patients with triglycerides ≥500 mg/dL—pharmacologic therapy is mandatory at this level 1, 3
- Do NOT start with statin monotherapy when triglycerides are ≥500 mg/dL, as statins provide only 10-30% triglyceride reduction and are insufficient for preventing pancreatitis 1, 3
- Do NOT ignore secondary causes of hypertriglyceridemia (uncontrolled diabetes, hypothyroidism, alcohol use, certain medications) before initiating fenofibrate 1, 3
Expected Outcomes and Treatment Goals
- Primary goal for severe hypertriglyceridemia: Reduce triglycerides to <500 mg/dL to eliminate pancreatitis risk 1, 3
- Secondary goal: Further reduce to <200 mg/dL (ideally <150 mg/dL) to reduce cardiovascular risk 1, 3
- Tertiary goal: Achieve non-HDL-C <130 mg/dL once triglycerides are controlled 3
- Fenofibrate typically provides 30-50% triglyceride reduction 1, 3, 5
- Reassess fasting lipid panel 4-8 weeks after initiating therapy 3, 4
Important Limitation
Fenofibrate was not shown to reduce coronary heart disease morbidity and mortality in patients with type 2 diabetes mellitus in major clinical trials (ACCORD, FIELD). 4, 2 The primary indication is triglyceride reduction to prevent pancreatitis and manage dyslipidemia, not cardiovascular risk reduction.
