    QT Interval Prolongation
  • QT interval prolongation and/or torsades de pointes (including fatalities) have occurred at doses at or below those recommended, in some cases when no known risk factors were present.
  • Because of potential for serious proarrhythmic effects and death, use only when response to other treatment is unacceptable (due to lack of efficacy or intolerable adverse effects).
  • Prior to administration, obtain 12-lead ECG to exclude the presence of prolonged QT interval (QTc interval >440 msec in males, >450 msec in females).
  • Do notadminister droperidol if QT interval is prolonged.
  • If potential benefit outweighs risk of serious arrhythmia, monitor for arrhythmia with ECG prior to administration and for 2–3 hours after completion of therapy.
  • Contraindicated in patients with known or suspected QT prolongation, including congenital long QT syndrome.
  • Use with extreme caution in patients at risk for prolonged QT syndrome (e.g., CHF, bradycardia, diuretic use, cardiac hypertrophy, hypokalemia, hypomagnesemia, use of other drugs known to prolong QT interval). Other risk factors may include age >65 years, alcohol abuse, and concomitant use of benzodiazepines, volatile anesthetics, or IV opiates. (See Prolonged QT Syndrome under Cautions.)
  • Initiate droperidol at low dose and increase with caution as needed to achieve desired effect.
