Cases of QT prolongation and/or torsade de pointes, some fatal, have been reported in patients receiving droperidol at doses at or below recommended doses. All patients should undergo a 12-lead ECG prior to administration of droperidol to determine if a prolonged QT interval (i.e., QTc greater than 440 msec for males or 450 msec for females) is present. Do not administer droperidol if there is a prolonged QT interval. Droperidol is contraindicated in patients with known or suspected QT prolongation, including patients with congenital long QT syndrome. Administer droperidol with extreme caution to patients who may be at risk for development of prolonged QT syndrome, are over 65 years old, abuse alcohol, or when used concomitantly with benzodiazepines, volatile anesthetics, and IV opiates. ECG monitoring should be performed prior to treatment and continued for 2 to 3 hours after completing treatment to monitor for arrhythmias .

Before Using droperidol

Tell your doctor if you have ever had any unusual or allergic reaction to droperidol or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of droperidol injection in children younger than 2 years of age. Safety and efficacy have not been established.
No information is available on the relationship of age to the effects of droperidol injection in geriatric patients. However, elderly patients are more likely to have age-related heart or kidney problems, which may require caution and an adjustment in the dose for patients receiving droperidol injection.

Proper Use of droperidol
A nurse or other trained health professional will give you droperidol in a hospital. Droperidol is given as a shot into a muscle or a vein.
Precautions While Using droperidol
Your doctor will check your progress after you receive droperidol. This will allow your doctor to see if the medicine is working properly and to check for unwanted effects.
Tell your doctor right away if you have any change in your heart rhythm. The symptoms may include feeling dizzy or faint, or having a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you or anyone in your family has ever had a heart rhythm problem such as QT prolongation.
Check with your doctor right away if you have difficulty breathing, a fast heartbeat, a high fever, a change in blood pressure, increased sweating, loss of bladder control, severe muscle stiffness, unusually pale skin, or tiredness. These could be symptoms of a serious condition called neuroleptic malignant syndrome (NMS).
Droperidol will add to the effects of alcohol and other central nervous system (CNS) depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever, allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates or other seizure medicines; and muscle relaxants. Check with your doctor before taking any of these medicines after you receive droperidol.
