Applies to:droperidol and Innovar (droperidol/fentanyl)
Consumer information for this interaction is not currently available.
MONITOR CLOSELY: The use of droperidol has been associated with QT interval prolongation, torsade de pointes and other serious arrhythmias, and sudden death. The concurrent administration of agents that can produce bradycardia, a known risk factor for QT interval prolongation, such as benzodiazepines and opiates, particularly intravenous opiates, may increase the risk of QT interval prolongation. In addition, hypotensive effects and central nervous system- and/or respiratory-depressant effects may be additively or synergistically increased in patients taking droperidol with benzodiazepines or opiates, especially in elderly or debilitated patients.
MANAGEMENT: Extreme caution and close monitoring are recommended if droperidol must be administered concomitantly with other bradycardic drugs. The dosage of droperidol should be individualized and titrated to the desired effect. Routine vital sign and ECG monitoring is recommended. When droperidol is used in combination with benzodiazepines or opiates, patients should be monitored for potentially excessive or prolonged CNS or respiratory depression as well as severe hypotension. Ambulatory patients should be counseled to avoid hazardous activities requiring mental alertness and motor coordination until they know how these agents affect them, and to notify their doctor if they experience excessive or prolonged CNS effects that interfere with their normal activities.
