Haldol Overview

Updated: 

Haldol is a prescription medication 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). Haldol 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). Haldol 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.

Haldol is in a group of medications called conventional antipsychotics. It works by decreasing abnormal excitement in the brain.

This medication comes as a tablet and concentrated liquid to take by mouth. It is usually taken two or three times a day, with or without food.

This medication is also available in an immediate release injectable form and extended release injectable form (Haldol decanoate) to be given directly into the muscle (IM) by a healthcare professional.

  • The immediate release injectable form for the use in the treatment of schizophrenia and for the control of tics and vocal utterances of Tourette’s Disorder can be given as often as every hour.
  • Haldol decanoate is usually administered every 4 weeks.

Common side effects of Haldol include rapid heartbeat, constipation, dry mouth, and drop in blood pressure upon standing.

Haldol can also cause blurred vision, drowsiness, and dizziness. Do not drive or operate heavy machinery until you know how Haldol affects you.

Haldol FDA 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 haloperidol have an increased chance of death during treatment.

Haldol 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 Haldol.
