DROPERIDOL INJECTION, USP
For IV or IM Use Only

INDICATIONS AND USAGE
Droperidol Injection is indicated to reduce the incidence of nausea and vomiting associated with surgical and diagnostic procedures.

IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS
Droperidol is contraindicated in patients with known or suspected QT prolongation.

Droperidol is contraindicated in patients with known hypersensitivity to the drug.

Droperidol is not recommended for any use other than for the treatment of perioperative nausea and vomiting in patients for whom other treatments are ineffective or inappropriate.

WARNINGS
Droperidol should be administered with extreme caution in the presence of risk factors for development of prolonged QT syndrome, such as: 1) clinically significant bradycardia, 2) any clinically significant cardiac disease,  3) treatment with Class I and Class III antiarrhythmics, 4) treatment with monoamine oxidase inhibitors , 5) concomitant treatment with other drug products known to prolong the QT interval and 6) electrolyte imbalance, in particular hypokalemia and hypomagnesemia, or concomitant treatment with drugs that may cause electrolyte imbalance.

Effects on Cardiac Conduction: A dose-dependent prolongation of the QT interval was observed within 10 minutes of droperidol administration in a study of 40 patients without known cardiac disease who underwent extracranial head and neck surgery.

Cases of QT prolongation and serious arrhythmias (e.g., torsade de pointes, ventricular arrhythmias, cardiac arrest, and death) have been observed during post-marketing treatment with droperidol.

For patients in whom the potential benefit of droperidol treatment is felt to outweigh the risks of potentially serious arrhythmias, ECG monitoring should be performed prior to treatment and continued for 2-3 hours after completing treatment to monitor for arrhythmias.

FLUIDS AND OTHER COUNTERMEASURES TO MANAGE HYPOTENSION SHOULD BE READILY AVAILABLE.

Patients who have received droperidol should have appropriate surveillance.

It is recommended that opioids, when required, initially be used in reduced doses.

Very rare reports of neuroleptic malignant syndrome have occurred in patients who have received droperidol.

Since it may be difficult to distinguish neuroleptic malignant syndrome from malignant hyperpyrexia in the perioperative period, prompt treatment with dantrolene should be considered if increases in temperature, heart rate or carbon dioxide production occur.

PRECAUTIONS
General: The initial dose of droperidol should be appropriately reduced in elderly, debilitated and other poor-risk patients.

The effect of the initial dose should be considered in determining incremental doses.

Droperidol can also alter circulation and may decrease pulmonary arterial pressure. Vital signs and ECG should be monitored routinely.

When the EEG is used for postoperative monitoring, it may be found that the EEG pattern returns to normal slowly.

Impaired Hepatic or Renal Function: Droperidol should be administered with caution to patients with liver and kidney dysfunction because of the importance of these organs in the metabolism and excretion of drugs.

Pheochromocytoma: In patients with diagnosed/suspected pheochromocytoma, severe hypertension and tachycardia have been observed after the administration of droperidol.

Drug Interactions:
Potentially Arrhythmogenic Agents: Any drug known to have the potential to prolong the QT interval should not be used together with droperidol.

Caution should be used when patients are taking concomitant drugs known to induce hypokalemia or hypomagnesemia as they may precipitate QT prolongation and interact with droperidol.

CNS Depressant Drugs: Other CNS depressant drugs have additive or potentiating effects with droperidol. When patients have received such drugs, the dose of droperidol required will be less than usual.

Pregnancy: Category C.
There are no adequate and well-controlled studies in pregnant women. Droperidol should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Labor and Delivery: There are insufficient data to support the use of droperidol in labor and delivery.

Nursing Mothers: It is not known whether droperidol is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when droperidol is administered to a nursing mother.

Pediatric Use: The safety of droperidol in children younger than two years of age has not been established.

ADVERSE REACTIONS
QT interval prolongation, torsade de pointes, cardiac arrest, and ventricular tachycardia have been reported in patients treated with droperidol. Some of these cases were associated with death. Some cases occurred in patients with no known risk factors, and some were associated with droperidol doses at or below recommended doses.

Physicians should be alert to palpitations, syncope, or other symptoms suggestive of episodes of irregular cardiac rhythm in patients taking droperidol and promptly evaluate such cases. The most common somatic adverse reactions reported to occur with droperidol are mild to moderate hypotension and tachycardia. If hypotension occurs and is severe or persists, the possibility of hypovolemia should be considered and managed with appropriate parenteral fluid therapy.

The most common behavioral adverse effects of droperidol include dysphoria, postoperative drowsiness, restlessness, hyperactivity and anxiety, which can either be the result of an inadequate dosage or of an adverse drug reaction.

Postoperative hallucinatory episodes (sometimes associated with transient periods of mental depression) have also been reported.

Other less common reported adverse reactions include anaphylaxis, dizziness, chills and/or shivering, laryngospasm and bronchospasm.

Elevated blood pressure, with or without pre-existing hypertension, has been reported following administration of droperidol combined with fentanyl citrate or other parenteral analgesics.

OVERDOSAGE
Manifestations: The manifestations of droperidol overdosage are an extension of its pharmacologic actions and may include QT prolongation and serious arrhythmias.

Treatment: In the presence of hypoventilation or apnea, oxygen should be administered and respiration should be assisted or controlled as indicated. A patent airway must be maintained. The patient should be carefully observed for 24 hours; body warmth and adequate fluid intake should be maintained.

If hypotension occurs and is severe or persists, the possibility of hypovolemia should be considered and managed with appropriate parenteral fluid therapy.

If significant extrapyramidal reactions occur in the context of an overdose, an anticholinergic should be administered.
