Haloperidol is an antipsychotic medication primarily used to treat various mental health conditions, including schizophrenia and acute psychosis. It works by blocking certain receptors in the brain, particularly dopamine receptors, which helps reduce symptoms like hallucinations and delusions. This medication can also be used to manage severe behavioral problems in children and to control tics and vocal utterances in Tourette syndrome. Haloperidol is available in various forms, including tablets and injections, and should be taken under the supervision of a healthcare professional due to potential side effects.
