Olanzapine induced hyponatremia and rhabdomyolysis

Abstract

AbstractRapid‐onset hyponatremia and rhabdomyolysis are rare, but potential, complications of olanzapine treatment. Hyponatremia, secondary to atypical antipsychotic use, has been reported in many case reports and is thought to be associated with an inappropriate antidiuretic hormone secretion syndrome. We report a case of sudden‐onset hyponatremia associated with a severe rhabdomyolysis resulting in a coma‐necessitating intensive care unit admission. His evolution was favorable after correction of all his metabolic disorders and olanzapine suspension.
