Does Fenofibrate Treat Gout?
Fenofibrate does not treat acute gout flares, but it effectively lowers serum uric acid by approximately 20% and halves the risk of future gout attacks when used in patients with both gout and hypertriglyceridemia. 1, 2
Guideline-Based Recommendations
The evidence presents a nuanced picture that depends on your clinical scenario:
When Fenofibrate IS Recommended
If your patient has gout AND requires lipid-lowering therapy for hypertriglyceridemia or mixed dyslipidemia, fenofibrate is the preferred lipid agent because it provides dual benefits: triglyceride reduction plus uric acid lowering. 1 The 2016 EULAR guidelines explicitly recommend considering fenofibrate for hyperlipidemia management in gout patients, emphasizing its dual urate-lowering and lipid-modifying effects. 1
When Fenofibrate Is NOT Recommended
The 2020 American College of Rheumatology guidelines conditionally recommend AGAINST adding or switching to fenofibrate solely for uric acid lowering when lipids are already adequately controlled with other agents (e.g., statins). 3, 1 The ACR panel judged that the modest additional urate-lowering benefit does not outweigh potential risks and side effects of changing an already-effective lipid regimen. 1
Clinical Decision Algorithm
Follow this approach based on your patient's lipid status:
Patient with gout + elevated triglycerides/mixed dyslipidemia needing first-line lipid therapy → Initiate fenofibrate as the primary lipid-lowering medication 1
Patient already on fenofibrate → Continue therapy to preserve dual benefits and avoid increasing gout risk 1
Patient with gout on statin with controlled lipids → Do NOT replace statin with fenofibrate solely for urate-lowering 1
Patient on statin with refractory hypertriglyceridemia despite therapy → Consider adding fenofibrate for the specific lipid indication 1
Mechanism and Magnitude of Effect
Fenofibrate produces clinically meaningful uric acid reduction through uricosuric effects:
- Reduces serum uric acid by approximately 20% (0.06 mmol/L or 1 mg/dL reduction) 3, 1, 4, 2
- Increases renal uric acid clearance by about 30% 1, 4
- Halves the risk of gout attacks over 5 years (HR 0.54,95% CI 0.41-0.70) 2
The FIELD trial demonstrated sustained uric acid reduction over 5 years, with first gout events occurring in only 2% of fenofibrate-treated patients versus 3% on placebo. 2 Among high-risk patients with baseline uric acid >0.42 mmol/L, cumulative gout incidence was 5.7% with fenofibrate versus 13.9% with placebo. 2
Additive Effect with Urate-Lowering Therapy
Fenofibrate provides additional uric acid reduction when combined with xanthine oxidase inhibitors (allopurinol or febuxostat). 5, 6, 7
In patients already on allopurinol or febuxostat, adding fenofibrate produced:
- Additional 23% reduction in serum uric acid (from 6.93 to 5.22 mg/dL) after 2 months 6
- Greater uric acid decrease (-2.40 mg/dL with fenofibrate vs. -1.81 mg/dL without, p=0.043) 5
- Increased uric acid excretion through enhanced renal clearance 7
The effect was reversible upon fenofibrate withdrawal, confirming causality. 6
Safety Considerations
Fenofibrate showed no adverse changes in renal or liver function tests in gout patients. 5 However, serum creatinine increased by 12% during treatment but returned to baseline upon withdrawal, representing a hemodynamic effect rather than true nephrotoxicity. 6
Common Pitfalls to Avoid
Do not use fenofibrate to treat acute gout flares – it has no role in acute symptom management; use colchicine, NSAIDs, or glucocorticoids instead 3
Do not add fenofibrate to a well-controlled statin regimen just for modest urate-lowering – the ACR advises against this practice 3, 1
Do not stop fenofibrate in a gout patient if it was appropriately prescribed for lipids – discontinuation will eliminate both lipid and urate benefits 1
Do not assume all fibrates have equal uricosuric effects – fenofibrate specifically reduces uric acid by 20%, while bezafibrate does not produce significant uric acid lowering 4
