Management of Gout
For acute gout attacks, treat immediately with corticosteroids, NSAIDs, or low-dose colchicine (1.2 mg followed by 0.6 mg one hour later), and do NOT initiate urate-lowering therapy during the acute flare. 1, 2
Acute Gout Management
First-Line Treatment Options
All three options are equally effective for pain relief with high-quality evidence 1, 2:
Colchicine: Use LOW-DOSE regimen only (1.2 mg loading dose, then 0.6 mg one hour later). High-dose regimens cause significantly more diarrhea (77% vs 23%) with no additional benefit 1. Start within 12 hours of flare onset for maximum efficacy 3.
NSAIDs: Any NSAID works equally well—indomethacin has no advantage over naproxen or ibuprofen despite traditional preference 1. Use with proton pump inhibitor if gastrointestinal risk exists 3.
Corticosteroids: Oral prednisone 30-35 mg/day for 3-5 days, or intra-articular injection after joint aspiration 3, 1.
Contraindications to Consider
- Colchicine: Avoid in severe renal/hepatic impairment and with strong CYP3A4 or P-glycoprotein inhibitors (cyclosporine, clarithromycin) 1, 3
- NSAIDs: Contraindicated in renal disease, heart failure, cirrhosis 1
- Corticosteroids: Use cautiously with infection risk, diabetes, fluid retention 1
Key Pitfall
Never start urate-lowering therapy during an acute attack—this will worsen and prolong the flare 3.
Long-Term Urate-Lowering Therapy (ULT)
When to Initiate ULT
Do NOT start ULT after a first gout attack or with infrequent attacks (<2 per year). 1 This is a strong recommendation based on moderate-quality evidence.
DO initiate ULT for patients with: 1, 3, 4
- ≥2 gout flares per year (recurrent gout)
- Tophaceous gout
- Radiographic joint damage from gout
- Chronic kidney disease with gout
- Urolithiasis with gout
- Young age at presentation (<40 years) 3
- Very high serum urate (>8 mg/dL or >476 µmol/L) 1
Shared Decision-Making Discussion
Before starting ULT, discuss with patients 1:
- Benefits: Reduces gout flares after 1 year (not within first 6 months), dissolves tophi, prevents joint damage
- Harms: Allopurinol causes rash (including rare severe reactions); febuxostat causes abdominal pain, diarrhea, musculoskeletal pain
- Costs: Allopurinol is inexpensive; febuxostat costs more
- Commitment: Lifelong therapy required for sustained benefit
- Alternative: Treat flares as they occur if patient prefers
First-Line ULT: Allopurinol
Allopurinol is the preferred first-line agent, including for patients with moderate-to-severe chronic kidney disease (stage ≥3). 4
Critical dosing strategy 4:
- Start LOW: ≤100 mg/day (lower doses like 50 mg/day in CKD stage ≥3)
- Titrate slowly: Increase by 100 mg every 2-4 weeks based on serum urate levels
- Target dose: Often requires 300-800 mg/day to reach target; don't stop at 300 mg if urate remains elevated
Alternative ULT: Febuxostat
Febuxostat 40 mg/day equals allopurinol 300 mg/day in efficacy 1. Use if:
- Allopurinol intolerance or allergy
- Failure to reach target on maximum allopurinol dose
Start at <40 mg/day and titrate up 4.
Treat-to-Target Strategy
Target serum urate <6 mg/dL (<360 µmol/L) for all patients with gout. 4 For patients with tophi, target <5 mg/dL (<300 µmol/L) for faster crystal dissolution 5.
- Measure serum urate every 2-4 weeks during titration
- Once at target, monitor every 6 months
- Adjust ULT dose to maintain target, not just prescribe fixed dose
Mandatory Flare Prophylaxis When Starting ULT
When initiating ULT, you MUST provide concomitant anti-inflammatory prophylaxis for at least 3-6 months (strong recommendation) 4. ULT paradoxically increases flare risk in first 6 months as crystals mobilize 1.
Prophylaxis options:
- Colchicine 0.5-1 mg/day (preferred) 1, 3
- Low-dose NSAID with gastroprotection if colchicine contraindicated 1, 3
Duration: Continue for minimum 3-6 months; longer if flares persist 1, 4. Stopping prophylaxis at 8 weeks causes spike in flare rates 2.
Lifestyle Modifications
Counsel ALL gout patients on 3:
- Weight loss if overweight (most impactful intervention)
- Avoid: Beer, spirits, sugar-sweetened beverages, excessive meat/seafood
- Encourage: Low-fat dairy products, regular exercise
- Limit: Heavy meals, fructose intake
Important caveat: While lifestyle changes modestly reduce serum urate, they rarely eliminate need for ULT in patients with recurrent gout 2. Don't withhold pharmacotherapy waiting for lifestyle changes alone.
Comorbidity Screening
Screen every gout patient for 3:
- Chronic kidney disease (check creatinine/eGFR)
- Cardiovascular disease and risk factors
- Hypertension, diabetes, hyperlipidemia
- Obesity
Medication adjustments:
- Stop diuretics if possible (major gout trigger) 6
- Consider losartan for hypertension (modest uricosuric effect) 6
- Consider fenofibrate for hyperlipidemia (modest uricosuric effect) 6
Common Pitfalls to Avoid
- Starting ULT during acute flare: Always treat flare first, wait for resolution
- Stopping at allopurinol 300 mg: This is often inadequate; titrate to serum urate target
- No flare prophylaxis with ULT: Guarantees treatment failure and patient frustration
- Stopping prophylaxis too early: Continue minimum 3-6 months, not just 8 weeks
- Treating first attack with lifelong ULT: Most patients don't need it after single attack
- Using high-dose colchicine: Low-dose equally effective with far fewer side effects
- Assuming normal serum urate excludes gout: During acute flares, urate may be normal 7
