Thorazine is an antipsychotic medication used to manage symptoms of psychotic disorders, treat schizophrenia, control nausea and vomiting, relieve anxiety before surgery, treat acute intermittent porphyria, relieve intractable hiccups, and with other medication to treat tetanus. This medication is also used to treat severe behavioural problems in children under 12 years old and as short-term treatment for hyperactive children.

Chlorpromazine is an antipsychotic drug that exerts psychotropic, sedative, and antiemetic activity at all levels of your central nervous system. This allows Thorazine to treat, manage, and relieve symptoms of various psychoses including schizophrenia, anxiety, and hiccups.

This medication is a first-line treatment for patients with schizophrenia and other psychotic disorders thanks to its effects on your central nervous system and dopamine receptors in your brain.
