Which statement about haloperidol is true?

• A. It is a typical antipsychotic.
• B. It is widely used for depression.
• C. It has no risk of EPS.
• D. It is sometimes used for Tourette's syndrome.

Answer: (D)

Haloperidol’s main action is blocking dopamine D2 receptors, which classifies it as a typical (high-potency) antipsychotic. Beyond treating psychosis, this strong dopamine blockade in motor pathways makes it effective at reducing tics in Tourette’s syndrome. For some patients with severe or treatment-refractory Tourette’s, haloperidol can substantially lessen motor and vocal tics, which is why the statement about its use in Tourette’s is true. It’s not used to treat depression, and it does carry a real risk of extrapyramidal symptoms, which is a major consideration in its use.
