Carfenazine is an antipsychotic medication of the phenothiazine class, used primarily for the treatment of schizophrenia and other psychotic disorders. It helps control symptoms such as delusions, hallucinations, and abnormal behavior by antagonizing dopamine receptors in the brain, thereby reducing psychotic episodes. It is typically administered via intramuscular injection in emergency situations or hospital settings for rapid symptom control in patients requiring immediate intervention.
