What would an overdose of haloperidol do?

An overdose of haloperidol, an antipsychotic medication, can lead to severe symptoms such as excessive sedation, respiratory depression, agitation, and extrapyramidal symptoms like dystonia and akathisia. In extreme cases, it may cause neuroleptic malignant syndrome, characterized by high fever, muscle rigidity, and autonomic instability. It is a medical emergency that requires immediate attention and management. If an overdose is suspected, seek emergency medical help promptly.
