title: Toxic psychosis: an unusual presentation of propranolol intoxication.
abstract: Timely diagnosis of acute propranolol intoxication requires a high index of suspicion and a knowledge of the multiple ways in which these patients may present to the emergency department. We report a case of severe propranolol intoxication that presented as an acute psychotic episode preceding cardiovascular decompensation and seizures by several hours. Though acute reversible psychosis has been appreciated after initiating or increasing propranolol dosage therapeutically, this association has not been reported in the literature regarding beta blocker overdose or intoxication. Propranolol psychosis and several other pertinent aspects of this case are discussed.
