title: Acute hallucinogenic reaction to carbinoxamine maleate.
abstract: A reaction to Rondec is reported. The patient presented with agitation and hallucinations and responded promptly to a trial of physostigmine. The clinical picture and prompt resolution of symptoms with physostigmine strongly suggest that the reaction was to the antihistamine component of the medication.
