<p>The administration of oral Potassium salts to persons with normal excretory mechanisms for potassium rarely causes serious hyperkalemia. However, if excretory mechanisms are impaired, hyperkalemia can result. Hyperkalemia, when detected, must be treated immediately because lethal levels can be reached in a few hours. If hyperkalemia occurs, treatment measures will include the followings: (1) Elimination of foods or medications containing potassium. (2) The intravenous administration of 300 to 500 ml/hr of dextrose solution (10 to 25%), containing 10 units of insulin/20 gm dextrose. (3) The use of exchange resins, hemodialysis or peritoneal dialysis.</p>
