title: Serotonin syndrome: an unusual cause of acute confusion and fever in the elderly.
abstract: Delirium is a common cause for hospital admission among elderly patients. Although infection is the most common explanation, there is a large number of other potential causes. We present a case of acute delirium due to serotonin syndrome, precipitated by concomitant prescription of clarithromycin and fluoxetine. The symptoms improved following treatment with a benzodiazepine and discontinuation of the fluoxetine. The diagnosis and management of serotonin syndrome is discussed.
