Gout - Causes


Other Medications. The list of drugs that cause hyperuricemia is long. In addition to diuretics and immunosuppressants, other agents that increase the risk for gout include the following:

  • Pyrazinamide (used to treat tuberculosis).
  • Aspirin. Low doses (not high doses) of aspirin reduce uric acid excretion and increase the chance for hyperuricemia. This may be a problem for older people who take baby aspirin (81 mg) to protect against heart disease. (High doses have the opposite effect.)
  • Niacin.


Exposure to Lead. Chronic occupational exposure to lead is associated with build-up of uric acid and a high incidence of gout. A 2002 study suggested that persistent low-level exposure to lead may also increase the risk for gout.

Other Conditions. A number of other conditions can cause gout. They include:

  • Leukemia
  • Lymphoma
  • Psoriasis
