Medications That Cause Gout

Diuretics are the most important and common cause of drug-induced hyperuricemia and gout, followed by immunosuppressants (particularly calcineurin inhibitors), low-dose aspirin, and certain chemotherapy agents. 1

Primary Offending Drug Classes

Diuretics (Highest Risk)

  • Loop diuretics (furosemide, bumetanide) and thiazide diuretics are the most clinically significant causes of drug-induced gout 2, 1
  • These agents decrease renal uric acid excretion by competing for tubular secretion pathways
  • Furosemide was identified as an independent risk factor for drug-induced gout in large-scale pharmacovigilance analysis 2
  • Clinical pitfall: Even low-dose thiazides used for hypertension can precipitate gout in susceptible individuals

Immunosuppressants

  • Calcineurin inhibitors (cyclosporine, tacrolimus) significantly increase uric acid reabsorption
  • Lenalidomide ranked as the most frequently implicated drug in gout-related adverse event reports 2
  • These are particularly problematic in transplant recipients who may already have compromised renal function

Cardiovascular Medications

Recent pharmacovigilance data reveal unexpected associations 3:

  • Some potassium-sparing diuretics showed positive signals for hyperuricemia
  • Certain calcium channel blockers were associated with increased gout risk (contrary to older literature)
  • Sacubitril-valsartan emerged as a novel candidate associated with gout 4
  • Rosuvastatin showed signals in FAERS database analysis 4

Low-Dose Aspirin

  • Doses <300 mg/day paradoxically decrease uric acid excretion
  • Commonly overlooked because patients take it for cardiovascular protection
  • Creates a therapeutic dilemma in patients with both cardiovascular disease and gout

Chemotherapy and Targeted Agents

  • Ruxolitinib (JAK inhibitor) 4
  • Cytotoxic agents causing tumor lysis syndrome
  • These increase uric acid production through rapid cell turnover

Newly Identified Agents (from 2025-2026 pharmacovigilance)

The following drugs have emerging evidence of gout association 4, 2:

  • Sitagliptin (DPP-4 inhibitor)
  • Treprostinil, epoprostenol, selexipag, iloprost (pulmonary hypertension agents)
  • Octreotide (somatostatin analog)
  • Riociguat (pulmonary hypertension)
  • Tafamidis (transthyretin stabilizer)
  • Dasabuvir/ombitasvir/paritaprevir/ritonavir (hepatitis C combination)

Mechanisms of Drug-Induced Hyperuricemia

Drugs precipitate gout through three pathways 1:

  1. Decreased renal uric acid excretion (most common): Diuretics, cyclosporine, low-dose aspirin, pyrazinamide
  2. Increased uric acid production: Cytotoxic chemotherapy, alcohol, fructose-containing medications
  3. Increased uric acid reabsorption: Calcineurin inhibitors, certain diuretics

Temporal Patterns

Critical timing: Approximately 75% of drug-induced gout events occur within 0.6 years (7.2 months) of drug initiation 4. More specifically, over 50% of cases occur within the first 30 days 2. The median time-to-onset is 31 days (IQR: 1-269 days) 2.

Clinical implication: Monitor uric acid levels and gout symptoms most vigilantly during the first month after starting high-risk medications.

Risk Factors for Drug-Induced Gout

Independent risk factors identified through machine learning analysis 2:

  • Male sex (significantly higher risk)
  • Older age (mean age 64.6 years for gout cases)
  • Pre-existing hyperuricemia
  • Chronic kidney disease
  • Concurrent use of multiple offending agents

Clinical Management Approach

When prescribing high-risk medications:

  1. Baseline assessment: Check serum uric acid before initiating diuretics, immunosuppressants, or other high-risk agents
  2. Monitoring frequency: Recheck uric acid at 1 month, then every 3-6 months during the first year
  3. Threshold for concern: Uric acid >8 mg/dL significantly increases gout risk 5
  4. Prophylaxis consideration: In patients with prior gout starting unavoidable high-risk medications, consider prophylactic colchicine or NSAIDs

Important caveat: The ACR strongly recommends against initiating urate-lowering therapy for asymptomatic hyperuricemia, even when drug-induced 6. Only 20% of patients with uric acid >9 mg/dL develop gout within 5 years, meaning 24 patients would need treatment for 3 years to prevent one gout flare.

Medications That Lower Uric Acid

Conversely, some drugs prescribed for other indications decrease uric acid 7:

  • Losartan (but not other ARBs) has uricosuric properties
  • Fenofibrate lowers uric acid through increased renal excretion
  • Certain NSAIDs (excluding aspirin) may have mild uricosuric effects

These agents may be preferentially selected in hypertensive or dyslipidemic patients with hyperuricemia or gout history.
