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 haloperidol have an increased chance of death during treatment.
Haloperidol 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 haloperidol. For more information, visit the FDA website: Web Site
WHY is this medicine prescribed?
Haloperidol is used to treat psychotic disorders (conditions that cause difficulty telling the difference between things or ideas that are real and things or ideas that are not real). Haloperidol is also used to control motor tics (uncontrollable need to repeat certain body movements) and verbal tics (uncontrollable need to repeat sounds or words) in adults and children who have Tourette's disorder (condition characterized by motor or verbal tics). Haloperidol is also used to treat severe behavioral problems such as explosive, aggressive behavior or hyperactivity in children who cannot be treated with psychotherapy or with other medications. Haloperidol is in a group of medications called conventional antipsychotics. It works by decreasing abnormal excitement in the brain.
HOW should this medicine be used?
Haloperidol comes as a tablet and concentrated liquid to take by mouth. It is usually taken two or three times a day. Take haloperidol 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 haloperidol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of haloperidol and gradually increase your dose. Your doctor may decrease your dose once your condition is controlled. Be sure to tell your doctor how you are feeling during your treatment with haloperidol.
Haloperidol may help control your condition, but will not cure it. Continue to take haloperidol even if you feel well. Do not stop taking haloperidol without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking haloperidol, you may experience difficulty controlling your movements.
Are there OTHER USES for this medicine?
Haloperidol is also used to treat confusion and difficulty thinking and understanding that is caused by severe physical or mental illness. Talk to your doctor about the possible risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
