Reports a case of recurrent hyponatremia in a 78-yr-old woman with depression. One week after the start of sertraline (50 mg/day) therapy, S was admitted to hospital for complaints of feeling depressed, weak, and lethargic. The setraline treatment was discontinued and fluids were restricted to 1 liter/day. After 1 wk, the hyponatremia had resolved and a regimen of lofepramine (70 mg/day) was started. Two weeks after starting the lofepramine, her serum sodium level fell, and the serum and urine osmolality rose. Lofepramine was discontinued and the 1 liter restriction was reinstated. Everything normalized within a week. Finally, the S was treated with ECT. She made a full recovery and was placed on clozapine. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
