Brand Names: Serenace, Haldol, Haldol Decanoate, Haloperidol LA, Peridol
Serenace (haloperidol) is an antipsychotic medication.
Haloperidol is used for treating schizophrenia, acute psychosis and it’s also used to control tics and vocal utterances that are part of Tourette’s syndrome.
Why is this medication 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.
What are the side effects of Haldol (haloperidol)?
The most common side effects associated with Haloperidol are:
- extrapyramidal effects (sudden, often jerky, involuntary motions of the head, neck, arms, body, or eyes, muscle stiffness, akathisia, Parkinsonism),
- dizziness,
- hyperactivity,
- tiredness, and
- nausea.
Other important side effects are:
- sedation,
- weight gain,
- erectile dysfunction,
- menstrual irregularities,
- insomnia,
- gynecomastia,
- dry mouth,

- constipation
Haldol may cause a condition called “orthostatic hypotension” during the early phase of treatment (first week or two). Orthostatic hypotension causes patients to become dizzy upon arising from a lying or sitting position because of a drop in blood pressure.
Haldol also may cause abnormal heart beats, sudden death, seizures, decreases in red and white blood cells, and withdrawal symptoms.
Elderly patients with dementia-related psychosis and treated with antipsychotic drugs such as Haldol are at an increased risk of death.
