The most common electrolyte derangements associated with RFS are hypophosphatemia and hypokalemia. Correction with a potassium phosphate solution is convenient and safe. Oral preparations are adequate in mild cases. Intravenous infusion can be administered if hypophosphatemia is severe. Intravenous doses of 0.08 mmol/kg body weight or an infusion of 15 mmol is adequate in many patients.5 Serial monitoring of potassium, phosphorus, and calcium is necessary to avoid complications.
