Consult expert advice.

If the diagnosis is made within 10 days of onset:

  • intravenous immunoglobulin
  • aspirin: e.g. 30 mg/kg/day in divided doses for 2 weeks

Thereafter:

  • aspirin, e.g. 3-5 mg/kg/day until the 6-8 week check echocardiograph
  • if coronary aneurysms are detected then aspirin should be continued indefinitely

Intravenous immunoglobulin may be given to patients diagnosed more than 10 days after onset if there is evidence of ongoing inflammation. A second course of immunoglobulin may be given for resistant or recurrent disease.

Immunoglobulin has been shown to:

  • reduce the incidence and severity of coronary aneurysms
  • resolve inflammation
  • relieve symptoms
