Fleet PHOSPHO-SODA is a laxative commonly used by many physicians for preparation of colonoscopy. Also, it is used frequently for treatment of constipation. Patients and their families can even buy it over the counter. Although it is relatively save, it does cause some adverse side effects which are so significant that physicians who prescribe it and the general public who buy it over the counter should be aware of. Volume depletion and electrolyte disturbance are commonly mentioned. Intravascular volume depletion might deteriorate renal function, and cause overt acute renal failure. Nevertheless, the most important and drastic side effects are electrolyte disturbance-hyperphosphatemia and hypocalcemia. We present a 78-year-old lady with hemiparesthesia, mimicking stroke after oral intake of undiluted Fleet PHOSPHO-SODA, 90 ml. Later, laboratory data revealed severe hyperphophatemia and hypocalcemia. Hemiparesthesia resolved completely after correction of hyperphophatemia and hypocalcemia.
