Drug Interactions Potassium supplements and potassium-sparing diuretics As noted above (“Derangements of Serum Electrolytes”), the net effect of fosinopril sodium and hydrochlorothiazide may be to elevate a patient’s serum potassium, to reduce it, or to leave it unchanged.
Potassium-sparing diuretics (spironolactone, amiloride, triamterene, and others) or potassium supplements can increase the risk of hyperkalemia.
