Short-term infusion (2 hours) of somatostatin has been shown to reduce urinary volume and free-water clearance in healthy persons (1). Although somatostatin is being widely used (2), water intoxication has not been described as a side effect. We report two cases of marked water retention and hyponatremia that occurred in patients receiving somatostatin therapy (given in continuous intravenous infusion at a rate of 250 μg/h after a loading dose of 250 μg). One patient had to be treated with hypertonic saline for hypo-osmolar coma.
Patient 1, a 44-year-old woman with multiple endocrine neoplasia, type 1, had had an insulinoma and
