Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the commonest cause of euvolemic hyponatremia. Several drugs are known to cause this syndrome. Pregabalin, a drug now used widely for a number of neurologic disorders, may cause hyponatremia secondary to salt wasting nephropathy. However, SIADH induced by pregabalin has been reported very infrequently in the literature. We report a case of hyponatremia in a patient started on pregabalin recently, who fulfilled criteria for SIADH and rapidly reversed on discontinuation of the drug. Awareness of this complication will help the clinician to diagnose and treat new onset hyponatremia in patients started on pregabalin.
