[Inappropriate ADH secretion-induced hyponatremia and associated with paroxetine use].

Introduction: Selective serotonin reuptake inhibitors (SSRI) are the most common antidepressants prescribed for elderly people. Although they are generally better tolerated than other antidepressant treatment classes, they can be responsible for potentially life-threatening hyponatremia, related to syndrome of inappropriate antidiuretic hormone secretion (SIADH).

Observation: A 64 years-old woman was hospitalized for cognitive function alteration and vomiting after introduction of paroxetine for depressive symptoms.
