 Action Effects apparently due to dopamine receptor blocking in CNS.

Drug Interactions ::


Alcohol and other CNS depressants: May result in increased CNS depression and may precipitate extrapyramidal reaction. Anticholinergics: May reduce therapeutic effects of thioridazine and worsen anticholinergic effects of thioridazine. May lead to tardive dyskinesia. Barbiturate anesthetics: Frequency and severity of neuromuscular excitation and hypotension may increase. Beta-blockers: May result in increased plasma levels of beta-blocker and thioridazine. Epinephrine: May antagonize effects of epinephrine. Lithium: May cause disorientation, unconsciousness and extrapyramidal effects.
