Use of High-Dose Intravenous Haloperidol in the Treatment of Agitated Cardiac Patients

Four cases are presented in which more than 100 mg/day of intravenous haloperidol were required for safe and effective control of confusion and agitation in coronary care unit patients.

Abstract

Although previous reports have documented the safe and effective use of intravenous haloperidol in agitated cardiac patients, the dosages advocated have in general been relatively low: 1 to 2 mg every 2 to 4 hours. In this report, the authors demonstrate that such doses may be insufficient to control severe agitation in coronary care unit patients. Four cases are presented in which more than 100 mg/day of intravenous haloperidol were required for safe and effective control of confusion and agitation.
