title: Management of neuroleptic malignant syndrome with anticholinergic medication.
abstract: Neuroleptic Malignant Syndrome (NMS) is a life-threatening adverse reaction arising from the use of neuroleptic medications. While dopaminergic agonists, dantrolrene and supportive care are traditionally utilized in the stabilization and management of NMS, anticholinergic medication may also prove effective therapy. Treatment with anticholinergic medication has been suggested in cases of NMS associated with mild hyperthermia. We describe a case of 17-y-old female, who was brought to the emergency department for a possible "acute dystonic reaction". The patient received 50 mg diphenhydramine i.v., which resulted in improvement in mental status. The patient was readmitted to the emergency department 1 d following discharge with symptoms similar, but now considering the diagnosis of NMS. Diphenhydramine 50 mg i.v. was again administered and resulted in significant improvement.
