Abstract
Oral sodium phosphate is known to be safe and it is widely used as a colon cleansing agent for colonoscopy. Yet several complicated cases with the development of electrolyte imbalance have been reported. We report here on 2 interesting cases: after administration of oral sodium phosphate, one patient presented with hyponatremia (Na, 122 mEq/L) with seizure and the other patient presented with hyponatremia (Na, 120 mEq/L) with a confused mentality. Brain imaging and electroencephalography showed no evidence of other causes for the seizure and mental change. We report here on two cases of hyponatremia with neurologic side effects, and this was all caused by oral sodium phosphate. We also include a review of the relevant literature.
