SPIRONOLACTONE is used commonly in conditions associated with secondary hyperaldosteronism.

This report concerns a patient without noteworthy renal disease in whom fatal hyperkalemia and hyperchloremic acidosis developed during treatment with spironolactone.

He had had two admissions to another hospital for ascites during the previous four months and was being treated with spironolactone (300 mg/day) and hydrochlorothiazide (50 mg/day).
