Acute Gout Flare Treatment
For an acute gout flare, initiate treatment within 24 hours using NSAIDs, colchicine, or oral corticosteroids as equally effective first-line monotherapy options, with selection based on renal function, cardiovascular risk, and gastrointestinal comorbidities. 1
First-Line Treatment Selection Algorithm
Step 1: Assess contraindications and comorbidities
- Severe renal impairment (eGFR <30 mL/min): Use oral corticosteroids (prednisone 30-35 mg daily for 5 days); avoid NSAIDs and colchicine 1, 2
- Cardiovascular disease or heart failure: Prefer corticosteroids over NSAIDs 2
- Active peptic ulcer disease or recent GI bleeding: Use corticosteroids or intra-articular injection; avoid NSAIDs 2
- Concurrent strong CYP3A4/P-glycoprotein inhibitors (clarithromycin, cyclosporine, ketoconazole, ritonavir, verapamil): Absolutely contraindicate colchicine; use corticosteroids or NSAIDs 1, 3
- Symptom onset >36 hours: Do not use colchicine; select NSAID or corticosteroid 3
Step 2: Choose first-line agent based on patient profile
NSAIDs (if no contraindications)
- Dosing: Naproxen 500 mg twice daily, indomethacin 50 mg three times daily, or sulindac 200 mg twice daily 3
- Duration: Continue full dose throughout entire attack until complete resolution; do not taper early 1, 3
- Efficacy: All NSAIDs demonstrate equivalent effectiveness; no single agent is superior 3
Colchicine (if presenting ≤36 hours from onset)
- Loading dose: 1.2 mg orally at first sign of flare, followed 1 hour later by 0.6 mg (total 1.8 mg) 1, 3
- Maintenance: After 12-hour pause, resume 0.6 mg once or twice daily until attack resolves 1, 3
- Efficacy: Achieves ≥50% pain reduction with NNT of 3-5, equivalent to high-dose regimens but with 23% vs 77% diarrhea rate 3
- Renal adjustment: In moderate impairment (CrCl 30-80 mL/min), use standard loading dose with close monitoring; reduce maintenance to 0.6 mg once daily 3
Oral Corticosteroids (preferred in renal/cardiac/GI disease)
- Dosing: Prednisone 0.5 mg/kg/day (approximately 30-35 mg) for 5-10 days at full dose then stop, OR 2-5 days at full dose followed by 7-10 day taper 1, 2
- Evidence: Level A evidence for equivalent efficacy to NSAIDs with fewer adverse events (27% vs 63% with indomethacin) 2
- No dose adjustment required for renal impairment 2
Intra-articular Corticosteroid Injection (for monoarticular involvement)
- Indication: 1-2 large, accessible joints 1, 2
- Dosing: Triamcinolone acetonide 40 mg for knee, 20-30 mg for ankle 2
- Advantage: Minimal systemic effects with targeted local control 2
Combination Therapy for Severe Attacks
Initiate combination therapy when:
- Polyarticular involvement (≥4 joints) 3
- Multiple large joints affected 1, 3
- Severe pain requiring rapid control 2
Recommended combinations:
- Colchicine + NSAID (synergistic anti-inflammatory effects) 3
- Oral corticosteroid + colchicine 1, 3
- Intra-articular steroid + any oral agent 1, 3
Avoid: NSAID + systemic corticosteroid (synergistic GI toxicity) 1, 3
Parenteral Options (when oral route unavailable)
- Intramuscular triamcinolone acetonide 60 mg as single injection 1, 2
- Intravenous methylprednisolone 0.5-2.0 mg/kg (40-140 mg for most adults), repeat as needed 2
- Strongly recommended over IL-1 inhibitors or ACTH for NPO patients 1, 2
Management of Ongoing Urate-Lowering Therapy
Do not discontinue allopurinol or febuxostat during an acute flare if already prescribed 1, 3
Do not initiate new urate-lowering therapy until flare completely resolves 3
Prophylaxis When Starting Urate-Lowering Therapy
- Colchicine 0.6 mg once or twice daily for at least 6 months when initiating allopurinol or febuxostat 1, 3
- Continue until serum urate <6 mg/dL achieved AND no clinical gout activity 3
- Alternative: Low-dose NSAID with PPI, or low-dose prednisone (<10 mg/day) as second-line 1, 3
Adjunctive Therapy
- Topical ice conditionally recommended as adjuvant treatment 1
Critical Timing Considerations
- Optimal window: Initiate treatment within 12-24 hours of symptom onset 1, 3
- Maximum efficacy for colchicine: Within 36 hours; do not start beyond this window 1, 3
- Delays beyond 24 hours markedly reduce effectiveness of all agents 3
Common Pitfalls to Avoid
- Never use obsolete high-dose colchicine regimen (0.5 mg every 2 hours); causes severe diarrhea in most patients with no additional benefit 3
- Never combine colchicine with strong CYP3A4/P-gp inhibitors in any patient with renal or hepatic impairment; risk of fatal toxicity 1, 3
- Never taper NSAIDs early; maintain full dose throughout entire attack 3
- Never use high-dose prednisone (>10 mg/day) for prophylaxis; increases adverse effects without proportional benefit 2
- Never prescribe colchicine to patients on verapamil; life-threatening interaction with 93-103% increase in colchicine levels 3
Monitoring for Inadequate Response
Define treatment failure as:
- <20% pain improvement within 24 hours, OR
- <50% improvement at ≥24 hours after initiating therapy 2
If inadequate response: Consider alternative diagnosis, switch to different monotherapy, or add second agent 2
