What is droperidol?
Droperidol is a sedative, tranquilizer, and anti-nausea medicine.
Droperidol is used to reduce nausea and vomiting caused by surgery or other medical procedures.
Droperidol may also be used for purposes not listed in this medication guide.
You should not use droperidol if you have a personal or family history of long QT syndrome.
Tell your caregivers at once if you have sudden dizziness with fast or pounding heartbeats, fluttering in your chest, or trouble breathing.
Before taking this medicine
You should not be treated with droperidol if you are allergic to it, or if you have a personal or family history of long QT syndrome.
Tell your doctor if you have ever had:
congestive heart failure;
very slow heartbeats;
an electrolyte imbalance (such as low levels of potassium or magnesium in your blood);
liver or kidney disease;
pheochromocytoma (tumor of the adrenal gland); or
Tell your doctor if you are pregnant or breastfeeding.
How is droperidol given?
Before you receive droperidol, your heart function may need to be checked using an electrocardiograph or ECG (sometimes called an EKG).
Droperidol is injected into a muscle, or is given as an infusion into a vein. You will receive this injection in a clinic or hospital setting prior to and/or during your surgery or medical procedure.
Your breathing, blood pressure, oxygen levels, kidney function, and other vital signs will be watched closely.
What happens if I miss a dose?
Since droperidol is used when needed, it does not have a daily dosing schedule.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include pounding heartbeats, trouble breathing, and severe dizziness or fainting.
What should I avoid after receiving droperidol?
Follow your doctor's instructions about any restrictions on food, beverages, or activity.
Droperidol side effects
Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Tell your caregivers right away if you have:

slow heart rate, weak pulse, fainting, slow breathing (breathing may stop);
bronchospasm (wheezing, chest tightness, trouble breathing);
twitching or uncontrollable movements of your eyes, tongue, jaw, or neck; or
severe nervous system reaction--very stiff (rigid) muscles, high fever, sweating, confusion, fast or uneven heartbeats, tremors.
Serious side effects may be more likely in older adults.
Common side effects include:
drowsiness, dizziness; or
feeling restless, anxious, or uneasy.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
What other drugs will affect droperidol?
Droperidol can cause a serious heart problem. Your risk may be higher if you also use certain other medicines for infections, asthma, heart problems, high blood pressure, depression, mental illness, cancer, malaria, or HIV.
Using other drugs that make you drowsy can worsen this effect for a short time after you have received droperidol. Ask your doctor before using opioid medication, a sleeping pill, a muscle relaxer, or medicine for anxiety or seizures.
Tell your doctor about all your other medicines, especially:
a diuretic or "water pill";
heart rhythm medication;
opioid pain medication;
