Used primarily in the treatment of schizophrenia and other psychotic disorders, it helps manage symptoms such as hallucinations, delusions, and disordered thinking. It is also prescribed for severe anxiety or agitation in certain clinical settings. As a phenothiazine antipsychotic, it works by blocking dopamine receptors in the brain, which helps regulate mood and behavior. Occasionally, it may be used off-label for nausea and vomiting when other treatments are not effective. Its sedative properties make it suitable for agitated patients, though long-term use requires monitoring due to risk of movement disorders.
