Síndrome serotoninérgica associada a uso de sertralina: relato de caso

Case report of serotonin syndrome in patient who initiated the use of sertraline at a dose greater than twice the recommended for the treatment of psychotic depression. The patient presented contracture of the limbs, puzzled look, mutism and blood pressure 230x110 mmHg. The syndrome is increasingly common, although it is not well recognized. Many medications can cause it and this possibility should be considered in patients taking serotonergic drugs presenting autonomic or mental disorders and neurological symptoms. The findings of clonus, oculogyric crisis, hyperreflexia and hypertonicity should lead to the medication review. Treatment focuses on interruption of causative agents, treatment of a possible hyperthermia and use of benzodiazepines to decrease hypertonus and neurological excitability.
