Potassium-sparing diuretics are generally used only in patients with normal renal function who are prone to significant hypokalemia. Some evidence indicates that spironolactone is particularly useful in patients with cirrhosis and in those with heart failure. Exercise caution in using potassium-sparing diuretics in either of these populations. Frequent determination of potassium levels is mandatory.
