Oral Fleet® Phospho®-Soda laxative-induced hyperphosphatemia and hypocalcemic tetany in an adult : Report of a case

This study was undertaken to report an adverse outcome of the routine use of Fleets Phospho-Soda for bowel cleansing and to review the available literature. Report of a case and review of the literature is presented. Administration of Fleets Phospho-Soda for bowel preparation in an adult resulted in hyperphosphatemia and hypocalcemic tetany. Review of the literature shows this to be the first such report. Further evaluation suggests a role for partial bowel obstruction and renal failure in this complication. Although Fleet Phospho-Soda solution continues to be a safe bowel preparation, caution should be used in adults with bowel obstruction and renal failure.
