We report a case of Neuroleptic malignant syndrome in 25-year old man. He was diagnosed substance induced psychosis  and controlled by antipsychotic drugs. This admission he had developed alteration of consciousness.  By his medication history, clinical symptoms, autonomic instability signs and investigation, Neuroleptic Malignant Syndrome was diagnosed in this patient.  It was essentially a diagnosis of exclusion, and treatment was mainly supportive in form of withdrawal of the neuroleptic medication (haloperidol, fluphenazine and chlorpromazine) and administration of bromocriptine. Although, relatively uncommon, NMS can be fatal.
