Neuroleptic Malignant Syndrome
Neuroleptic malignant syndrome is a life-threatening reaction that occasionally occurs in response to neuroleptic medication. Symptoms include high fever, confusion, rigid muscles, variable blood pressure, sweating, and fast heart rate. Complications may include high blood pressure, kidney failure, or seizures and improper functioning of the autonomic nervous system. As soon as the syndrome (disorder) is recognized, drug use is discontinued and each symptom is treated medically.
