Ziprasidone is not approved by the FDA for use in the treatment of behavioral disorders in older adults with dementia. Talk to the doctor who prescribed this medication, if you, a family member, or someone you take care of is taking ziprasidone to treat behavioral problems associated with dementia.

Why is this medication prescribed?
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 I 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?
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 controls schizophrenia but does not cure it. Continue to take ziprasidone even if you feel well. Do not stop taking ziprasidone without talking to your doctor.
