Duloxetine‐induced syndrome of inappropriate antidiuretic hormone secretion in a patient with neuropathic pain

Abstract

Key Clinical MessageSyndrome of inappropriate antidiuretic hormone secretion (SIADH) induces hyponatremia accompanied by uric acid reduction. We report a case of a patient with small‐cell lung cancer who developed SIADH with hypouricemia after duloxetine treatment and discuss the potential underlying mechanisms. SIADH and hypouricemia improved after duloxetine was switched to mirogabalin.
