Postoperative hypocalcemic tetany caused by fleet® Phospho®-Soda preparation in a patient taking alendronate sodium

Abstract
This case report describes a patient who was previously prescribed alendronate (Fosamax) and presented with postoperative hypophosphatemia and hypocalcemic tetany after bowel preparation with Fleet Phospho-Soda. This report suggests that patients taking bone metabolism regulators may not be able to respond appropriately to hypocalcemic stressors.
