Haloperidol (haloperidol) — Uses, Dosage, Side Effects & Safety
Drug class: Typical antipsychotic (butyrophenone class)
Overview
Haloperidol is a prescription medicine used to treat certain mental and mood disorders, including schizophrenia, acute psychosis, and severe behavioral problems. It is also sometimes used to control tics and vocal utterances in Tourette syndrome, and to manage severe agitation or delirium in hospital settings. Haloperidol works by helping to restore the balance of certain natural substances (neurotransmitters) in the brain, particularly dopamine. By blocking dopamine receptors, it helps reduce symptoms like hallucinations, delusions, agitation, and disorganized thinking. Key points: Haloperidol can cause drowsiness, movement problems, and other side effects. It should be taken exactly as prescribed, and regular follow-up with your healthcare provider is important to monitor for side effects and effectiveness.
