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 ziprasidone have an increased risk of death during treatment.Older adults with dementia may also have a greater chance of having a stroke or mini-stroke during treatment. If you experience any of the following symptoms, call your doctor immediately: slow or difficult speech, sudden dizziness or faintness, or weakness or numbness of an arm or leg.

Ziprasidone is not approved by the Food and Drug Administration (FDA) for the treatment of behavior problems in older adults with dementia.

Why is this medication prescribed? Return to top

Ziprasidone is used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions). It is also used to treat episodes of mania (frenzied, abnormally excited or irritated mood) or mixed episodes (symptoms of mania and depression that happen together) in patients with bipolar disorder (manic depressive disorder; a disease that causes episodes of depression, episodes of mania, and other abnormal moods). Ziprasidone is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.

How should this medicine be used? Return to top

Ziprasidone comes as a capsule to take by mouth. It is usually taken twice a day with food. Take ziprasidone at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ziprasidone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor may start you on a low dose of ziprasidone and gradually increase your dose.

Ziprasidone may help control your symptoms but will not cure your condition. Continue to take ziprasidone even if you feel well. Do not stop taking ziprasidone without talking to your doctor.
