View full FDA label ↗Fluphenazine is a medication used to help manage symptoms of psychotic disorders. It works by affecting certain chemicals in the brain to help improve mood and behavior. You can take it in pill form, usually starting with a dose between 2.5 to 10 mg per day, divided into smaller doses throughout the day, and it may be increased if needed, with a maximum daily dose of 40 mg. A key warning is that it is not approved for treating elderly patients with dementia-related psychosis due to an increased risk of death. Additionally, if you're taking alcohol or other central nervous system depressants, be cautious, as they can enhance the effects of fluphenazine.
