Syndrome of inappropriate antidiuretic hormone (SIADH) in an 80-year-old woman given clomipramine

Abstract

The author describes the syndrome of inappropriate antidiuretic hormone, with serum sodium decreasing from 137 mEq/L to 122 mEq/L in an 80-year-old woman prescribed clomipramine. The patient's delirium and serum sodium were slow to normalize, prolonging her hospital stay and delaying treatment of her depression.
