Chlorpromazine is an antipsychotic medication primarily used to treat symptoms of schizophrenia and other mental health disorders. It works by affecting certain neurotransmitters in the brain, particularly dopamine, which helps to reduce hallucinations and delusions. Originally developed in the 1950s, chlorpromazine was one of the first medications used in psychiatric treatment. It can also be prescribed for severe anxiety, nausea, and to manage agitation in various conditions. Like all medications, it may have side effects, including drowsiness and weight gain, and should be used under medical supervision.
