Management of Acute Gout Flare
For an acute gout flare, initiate treatment within 24 hours using NSAIDs, colchicine, or corticosteroids as first-line monotherapy, selecting the agent based on renal function, cardiovascular risk, and gastrointestinal comorbidities; for long-term management after recurrent flares, start urate-lowering therapy with allopurinol (beginning at ≤100 mg daily and titrating to achieve serum urate <6 mg/dL) while providing colchicine prophylaxis for at least 6 months. 1, 2, 3
Acute Flare Management
First-Line Treatment Selection Algorithm
Step 1: Assess timing and contraindications
- Treatment must be started within 24 hours of symptom onset for optimal efficacy; delays beyond this window markedly reduce effectiveness of all agents. 2, 3
- For colchicine specifically, do not initiate after 36 hours from symptom onset—efficacy drops sharply beyond this timeframe. 2, 3
Step 2: Select agent based on patient factors
Choose NSAIDs when:
- Patient has normal renal function (eGFR ≥60 mL/min), no cardiovascular disease, no heart failure, no cirrhosis, no active peptic ulcer disease, and not on anticoagulation. 1, 2
- Use full FDA-approved doses: naproxen 500 mg twice daily, indomethacin 50 mg three times daily, or sulindac 200 mg twice daily. 1, 3
- Continue at full dose throughout the entire attack until complete resolution—do not taper early. 1, 3
Choose corticosteroids when:
- Patient has severe renal impairment (eGFR <30 mL/min), cardiovascular disease, heart failure, cirrhosis, peptic ulcer disease, or is on anticoagulation. 1, 2
- Prednisone 0.5 mg/kg per day (approximately 30–35 mg daily) for 5–10 days at full dose then stop abruptly, OR give 2–5 days at full dose followed by 7–10 day taper. 1, 2
- For monoarticular or oligoarticular involvement of large accessible joints, intra-articular corticosteroid injection (triamcinolone acetonide 40 mg for knee, 20–30 mg for ankle) is highly effective. 2, 3
- Intramuscular triamcinolone acetonide 60 mg is appropriate when oral access is not feasible (NPO status, surgical conditions). 2
Choose colchicine when:
- Symptom onset is ≤36 hours, patient has normal-to-moderate renal function (CrCl ≥30 mL/min), and is NOT taking strong CYP3A4 or P-glycoprotein inhibitors (clarithromycin, cyclosporine, ketoconazole, ritonavir, verapamil). 2, 3
- Loading dose: 1.2 mg at first sign of flare, followed 1 hour later by 0.6 mg (total 1.8 mg). 2, 3
- After 12-hour pause, resume 0.6 mg once or twice daily until attack resolves. 2, 3
- This low-dose regimen achieves ≥50% pain reduction with number needed to treat of 3–5, equivalent efficacy to obsolete high-dose protocols but with significantly fewer gastrointestinal adverse effects (23% vs 77% diarrhea). 3
Combination Therapy for Severe Attacks
Initiate combination therapy when:
- Polyarticular involvement (≥4 joints) or multiple large joints are affected. 3
- Severe pain requiring rapid control with sustained anti-inflammatory coverage. 2
Acceptable combinations:
Avoid:
- NSAIDs + systemic corticosteroids due to synergistic gastrointestinal toxicity. 3
Critical Contraindications
Colchicine absolute contraindications:
- Severe renal impairment (CrCl <30 mL/min). 2, 3
- Concurrent use of strong CYP3A4 or P-glycoprotein inhibitors (clarithromycin, cyclosporine, ketoconazole, ritonavir, verapamil), especially with any degree of renal or hepatic impairment—this combination can cause fatal multiorgan toxicity. 2, 3
NSAID absolute contraindications:
- Severe renal impairment (eGFR <30 mL/min)—NSAIDs can precipitate or worsen acute kidney injury. 2
- Active or recent gastrointestinal bleeding. 3
Corticosteroid absolute contraindications:
Long-Term Management After Recurrent Flares
Indications to Initiate Urate-Lowering Therapy
Strongly recommended after first flare when:
- Subcutaneous tophi are present. 3
- Radiographic joint damage attributable to gout. 3
- Chronic kidney disease stage ≥3. 3
Conditionally recommended after first flare when:
- Recurrent flares (≥2 per year). 1, 4, 5
- Urolithiasis. 4
- Patient preference for early intervention. 3
- Young age at disease onset. 3
- Serum urate >9 mg/dL. 3
Do NOT initiate urate-lowering therapy:
- During an acute gout flare if patient is not already on therapy—wait until flare completely resolves. 3
- If patient is already on urate-lowering therapy when flare occurs, continue it without interruption. 2, 3
Urate-Lowering Therapy Protocol
Allopurinol initiation and titration:
- Start at low dose: ≤100 mg daily (lower in CKD—consider 50 mg daily in severe renal impairment). 3, 5
- Titrate upward by 100 mg every 2–4 weeks until serum urate target <6 mg/dL is achieved. 3, 5
- In patients with CKD stage 3 or worse, consider HLA-B*58:01 screening before starting allopurinol due to markedly increased risk of fatal hypersensitivity reactions. 3
Mandatory prophylaxis during urate-lowering therapy initiation:
- Provide colchicine prophylaxis 0.6 mg once or twice daily for at least 6 months when starting or adjusting urate-lowering therapy. 1, 3, 6
- Continue prophylaxis for 3 months after achieving target serum urate if no tophi present, or 6 months after achieving target if tophi present. 3
- If colchicine contraindicated or not tolerated, use low-dose NSAID with proton pump inhibitor, or low-dose prednisone (<10 mg/day) as second-line prophylaxis. 1, 2, 6
Febuxostat alternative:
- Start at ≤40 mg daily and titrate to achieve serum urate <6 mg/dL. 3
- Febuxostat is associated with increased all-cause and cardiovascular mortality compared to allopurinol and is not routinely recommended as first-line therapy. 4
- Same colchicine prophylaxis protocol applies when initiating febuxostat. 3
Common Pitfalls to Avoid
- Do not delay acute treatment beyond 24 hours—efficacy of all agents decreases significantly. 2, 3
- Do not use colchicine after 36 hours from symptom onset—it becomes ineffective. 2, 3
- Do not reduce NSAID dose early during acute attack—maintain full dose until complete resolution. 1, 3
- Do not use high-dose prednisone (>10 mg/day) for prophylaxis—increases adverse effects without proportional benefit. 2, 3
- Do not start allopurinol at 300 mg daily—"go low, go slow" approach (starting at 100 mg and titrating) reduces flares and toxicity risk. 3
- Do not stop urate-lowering therapy during an acute flare if patient is already on it—continuation maintains serum urate control and does not worsen the attack. 2, 3
- Do not omit colchicine prophylaxis when starting urate-lowering therapy—omission markedly raises the risk of acute flares during the first 6 months. 3, 6
