[Serotonin syndrome secondary to the association of paroxetine and amitriptyline: a case report].

Serotonin syndrome is an iatrogenic disorder induced by serotonergic drug. It is characterised by a symptomatic polymorphism that may create confusion with other clinical conditions, delaying diagnosis and putting the vital prognosis at risk. In light of a case report and a literature review, we here report the clinical case of a patient presenting with confusion, psychomotor agitation, hyperreflexia and spontaneous myoclonus following simultaneous use of paroxetine and amitriptyline. The diagnosis of serotonin syndrome was made after ruling out other possible diagnoses. The patient was admitted to the intensive care unit. This clinical case highlights the importance of thoroughly understanding the clinical manifestations of serotonin syndrome to ensure early and appropriate therapeutic management.
