Aldax Warnings

Potassium supplementation, either in the form of medication or as a diet rich in potassium, should not ordinarily be given in association with Spironolactone therapy. Excessive potassium intake may cause hyperkalemia in patients receiving spironolactone. Spironolactone should not be administered concurrently with other potassium-sparing diuretics.
Spironolactone, when used with ACE inhibitors or indomethacin, even in the presence of a diuretic, has been associated with severe hyperkalemia. Extreme caution should be exercised when spironolactone is given concomitantly with these drugs.
25 mg: Hyperkalemia in patients with severe heart failure: Hyperkalemia may be fatal. It is critical to monitor and manage serum potassium in patients with severe heart failure receiving Spironolactone.
Avoid using other potassium-sparing diuretics. Avoid using oral potassium supplements in patients with serum potassium > 3.5 mEq/L. RALES excluded patients with a serum creatinine > 2.5 mg/dL or a recent increase in serum creatinine > 2.5 mg/dL or a recent increase in serum creatinine > 25%.
The recommended monitoring for potassium and creatinine is one week after initiation or increase in dose of spironolactone, monthly for the first 3 months, then quarterly for a year, and then every 6 months. Discontinue or interrupt treatment for serum potassium > 5 mEq/L or for serum creatinine > 4 mg/dL. Spironolactone should be used with caution in patients with impaired hepatic function because minor alterations of fluid and electrolyte balance may precipitate hepatic coma. Lithium generally should not be given with diuretics.
50 mg: Spironolactone should be used with caution in patients with impaired hepatic function because minor alterations of fluid and electrolyte balance may precipitate hepatic coma. Lithium generally should not be given with diuretics.
