From the Guidelines
Medications to treat hyperkalemia should be administered as needed, with the frequency of administration depending on the severity of the condition, patient response, and potassium levels, which should be monitored regularly. For acute hyperkalemia, treatment with a combination of calcium carbonate and hyperosmolar sodium, insulin with or without glucose, and/or beta adrenoceptor agonists can be initiated immediately to stabilize the myocardial cell membrane and transfer K+ into the cells 1. However, since insulin, salbutamol, and bicarbonate do not increase K+ excretion and only provide temporary benefit, treatment with a K+ lowering agent, such as loop diuretics or potassium binders, should be initiated as early as possible to manage hyperkalemia 1. Some key points to consider when administering medications for hyperkalemia include:
- The use of calcium gluconate to stabilize cardiac membranes
- The administration of insulin with glucose to shift potassium into cells
- The use of albuterol nebulization to help lower potassium levels
- The administration of sodium bicarbonate in acidotic patients
- The use of sodium polystyrene sulfonate, patiromer, or sodium zirconium cyclosilicate for ongoing removal of potassium
- The administration of loop diuretics in patients with adequate kidney function The frequency of administration of these medications can vary, but some general guidelines include:
- Calcium gluconate: can be repeated after 5-10 minutes if ECG abnormalities persist
- Insulin with glucose: can be repeated if needed, with effects lasting 4-6 hours
- Albuterol nebulization: can be administered every 2 hours
- Sodium bicarbonate: can be repeated based on pH monitoring
- Sodium polystyrene sulfonate: can be given every 4-6 hours
- Patiromer or sodium zirconium cyclosilicate: can be given daily, with the frequency of administration depending on the specific medication and patient response
- Loop diuretics: can be administered multiple times daily in patients with adequate kidney function.
From the FDA Drug Label
The average total daily adult dose of Sodium Polystyrene Sulfonate is 15 g to 60 g, administered as a 15 g dose (four level teaspoons), one to four times daily. Rectal The average adult dose is 30 g to 50 g every six hours.

Treatment of Hyperkalemia
The frequency of administering medications to treat hyperkalemia is not explicitly stated in the provided studies. However, the studies outline the various treatment modalities for acute hyperkalemia, including:
- Elimination of reversible causes (diet, medications) 3
- Rapidly acting therapies that shift potassium into cells and block the cardiac membrane effects of hyperkalemia, such as calcium gluconate, insulin, and beta-agonists 3, 4
- Measures to facilitate removal of potassium from the body, including saline diuresis, oral binding resins, and hemodialysis 3, 5
Administration of Medications
The studies suggest that treatment should be started with calcium gluconate to stabilize cardiomyocyte membranes, followed by insulin injection, and beta-agonists administration 3. The administration of insulin and glucose is a common therapy for hyperkalemia, but it requires careful monitoring to avoid hypoglycemia 6. The frequency of administration of these medications is not specified, but it is recommended to monitor patients hourly for at least 4-6 hours after administration to reduce the risk of hypoglycemia 6.
Key Considerations
The treatment of hyperkalemia should be individualized based on the severity of the condition, the presence of electrocardiography changes, and the patient's underlying medical conditions 4, 5. The studies emphasize the importance of prompt detection and proper treatment to prevent lethal outcomes 3, 5.
