Answer 10 Quetiapine. Typical antipsychotics, such as haloperidol, and newer agents with dopamine D2 receptor affinity are avoided in the long-term treatment of visual hallucinations and agitation because of potential worsening of motor symptoms, cognitive decline, delirium, and features of neuroleptic malignant syndrome associated with dopamine receptor blockage.1 Amitriptyline is not indicated for psychosis.
