Why gout and kidney disease are connected
Gout is caused by high blood levels of uric acid (hyperuricemia), which can crystallize in joints — most often the big toe — and trigger painful inflammation. The kidneys excrete most of the body's uric acid, so reduced kidney function leads directly to higher uric acid levels and more frequent gout. Conversely, untreated gout and very high uric acid can themselves contribute to kidney damage. Effective gout management is part of comprehensive nephrology care.
Medications for acute gout flares
Steroids (preferred in CKD)
Oral prednisone or an intramuscular steroid injection is often the safest choice for acute gout in patients with kidney disease. Steroids do not stress the kidneys and reliably reduce inflammation. A typical course is 3–5 days at a moderate dose. Steroid injections directly into the affected joint can be especially effective when only one or two joints are involved.
Colchicine
Colchicine reduces gout inflammation when started early in a flare. It must be dose-adjusted in CKD because the kidneys clear it. The typical low-dose regimen is well-tolerated even in moderate CKD. Patients on dialysis or with severe CKD may need substantially reduced or no colchicine. Side effects (nausea, diarrhea) are dose-related.
NSAIDs (generally avoid in CKD)
In patients with healthy kidneys, NSAIDs are a standard treatment for gout flares. In patients with CKD, NSAIDs are usually avoided because of the risk of acute kidney injury. See the NSAIDs and Your Kidneys page for more.
Medications for long-term uric acid lowering
Allopurinol
Allopurinol blocks the enzyme xanthine oxidase, which produces uric acid. It is the first-line preventive medication for most patients with recurrent gout, including those with kidney disease. Dose is started low and slowly increased to target a uric acid level under 6 mg/dL. CKD patients require slower titration to avoid hypersensitivity reactions. Patients with Asian ancestry should be screened for the HLA-B*5801 allele before starting, as it predicts a serious skin reaction.
Febuxostat
Febuxostat is an alternative xanthine oxidase inhibitor for patients who cannot tolerate allopurinol. It is more expensive and has a labeled cardiovascular warning, so allopurinol remains preferred when usable.
Probenecid
Probenecid increases urinary excretion of uric acid. It is generally not used in patients with significant CKD because it loses effectiveness when kidney function is impaired and may worsen kidney stones.
Pegloticase
Pegloticase is an infused medication used for severe, treatment-refractory gout. It is reserved for specialty management.
Practical tips
- Talk to your nephrologist before starting any new gout medication
- Don't stop preventive uric-acid-lowering medication during a flare — keep taking it even as you treat the flare
- Hydrate adequately
- Reduce dietary triggers when possible: alcohol (especially beer), red meat, organ meats, and fructose-sweetened beverages
- Check uric acid 4–6 weeks after starting or adjusting medication, then every 3–6 months once stable
