IMPORTANT WARNING:

Studies have shown that older adults with dementia (a brain disorder that affects the ability to remember, think clearly, communicate, and perform daily activities and that may cause changes in mood and personality) who take antipsychotics (medications for mental illness) such as fluphenazine have an increased risk of death during treatment.

Fluphenazine is not approved by the Food and Drug Administration (FDA) for the treatment of behavior problems in older adults with dementia. Talk to the doctor who prescribed this medication if you, a family member, or someone you care for has dementia and is taking fluphenazine.

Why is this medication prescribed?

Fluphenazine is an antipsychotic medication used to treat schizophrenia and psychotic symptoms such as hallucinations, delusions, and hostility.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medicine be used?

Fluphenazine comes as a tablet or oral liquid (elixir and concentrate) to take by mouth. It is usually taken two or three times a day and may be taken with or without food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take fluphenazine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Fluphenazine oral liquid comes with a specially marked dropper for measuring the dose. Ask your pharmacist to show you how to use the dropper. Do not allow the liquid to touch your skin or clothing; it can cause skin irritation. Dilute the concentrate in water, Seven-Up, carbonated orange beverage, milk, or V-8, pineapple, apricot, prune, orange, tomato, or grapefruit juice just before taking it. Do not use beverages containing caffeine (coffee, tea, and cola) or apple juice.

Continue to take fluphenazine even if you feel well. Do not stop taking fluphenazine without talking to your doctor, especially if you have taken large doses for a long time. Your doctor probably will want to decrease your dose gradually. This drug must be taken regularly for a few weeks before its full effect is felt.

What special precautions should I follow?

Before taking fluphenazine,

• tell your doctor and pharmacist if you are allergic to fluphenazine or any other drugs.
