Prolixin is an antipsychotic medication used to treat a variety of mental illnesses, such as schizophrenia and bipolar disorder. It contains the active ingredient fluphenazine, which belongs to a class of medications called phenothiazines. It works by blocking dopamine receptors in the brain, which helps regulate mood and behavior.

Fluphenazine is one of many drugs classified as a 'typical' or 'first-generation' antipsychotic. Prolixin works by blocking certain dopamine receptors in the brain, which helps to reduce symptoms such as delusions, hallucinations, and disorganized thinking. Prolixin may be used alone or with other medication.

Uses and Dosage

Fluphenazine comes in the form of tablet to take by mouth three or four times a day. Take it with food or milk if stomach upset occurs unless directed otherwise by your doctor. Do not stop taking Fluphenazine suddenly without consulting your doctor. Some conditions may worsen if the medication is suddenly stopped. Use Fluphenazine regularly to get the most benefit from it. Remember to use it at the same time each day.

The recommended dosage of Fluphenazine for adults depends on the condition being treated and may vary between 2.5 to 10 mg orally in divided doses every 6 to 8 hours for the initial dose, with a maintenance dose of 1 to 5 mg/day. The maximum daily dose may be up to 40 mg/day. However, note that dosage recommendations may vary based on individual medical history, so consult with a doctor or healthcare provider to determine the appropriate dosage for an individual.
