Neuroleptic Malignant Syndrome (NMS) is a medical emergency of infrequent presentation in Emergency department, which is associated with the use of psychotropic agents, classical and atypical antipsychotics. We report a case involving a 56-year-old male patient diagnosed with schizophrenia and depression for 30 years, who had been receiving Amisulpride, Trifluoperazine, Clozapine, and Amitryptiline as part of his treatment. This patient presented with symptoms of NMS with fever, muscle rigidity, altered mental state, elevated CPK, Urea, and S. Creatinine levels. NMS may be responsible for serious rhabdomyolysis, acute respiratory distress syndrome, and disseminated intravascular coagulation. We hypothesize the occurrence of acute renal failure precipitated by NMS. His treatment included the withdrawal of all psychotropic agents, Bromocriptine, and other supportive measures.
