Table of contents:

Thorazine, also known as Chlorpromazine, is an antipsychotic medication used to treat psychotic disorders such as schizophrenia or manic depression, and certain mental/mood disorders. It works by blocking certain chemicals in the brain to help reduce symptoms such as hallucinations, delusions, and agitation.

Chlorpromazine is a powerful antipsychotic medication used to treat severe mental illnesses such as schizophrenia and bipolar disorder. It can be used to treat nausea and vomiting, anxiety before surgery, and other conditions.

Uses and Dosage

Chlorpromazine is available in tablet form and is taken orally with or without food as prescribed by the healthcare provider, usually 2-4 times a day. The dosage is determined based on the individual's medical condition, age, and response to treatment, and in children, it is also based on weight. To minimize the possibility of side effects, the healthcare provider may start the patient on a low dose and gradually increase it. Follow the healthcare provider's instructions meticulously.

The dose varies depending on the condition you are taking chlorpromazine for. In general, the typical dose ranges from 10 mg to 50 mg by mouth two to four times a day. If you are taking chlorpromazine for restlessness and anxiety before surgery, the typical dose is 25 mg to 50 mg by mouth once, 2 to 3 hours before your procedure.
