Fluphenazine is an antipsychotic medication primarily used to treat symptoms of schizophrenia and other psychotic disorders. It works by affecting certain chemicals in the brain, particularly dopamine, which helps to reduce hallucinations, delusions, and agitation. This medication is available in various forms, including tablets and injections. While effective, Fluphenazine can cause side effects such as drowsiness, dry mouth, and weight gain. It is important for patients to follow their healthcare provider's instructions and report any unusual symptoms or concerns during treatment.
