Interactions between your drugs

Major

droPERidol fentaNYL

Applies to: droperidol / fentanyl and droperidol / fentanyl

DroPERidol can occasionally cause excessively slow heart rate and low blood pressure, and using it with fentaNYL may increase those risks. An excessively slow heart rate can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Talk to your doctor if you have any questions or concerns. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, or irregular heartbeat during treatment with these drugs, whether together or alone. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Major

droPERidol metoclopramide

Applies to: droperidol / fentanyl and Metozolv ODT (metoclopramide)

Using metoclopramide together with droPERidol is not recommended. Treatment with either medication alone can cause Parkinson-like symptoms and abnormal muscle movements, and combining them may increase that risk. The most serious of the movement disorders associated with the use of these medications is a condition known as tardive dyskinesia (TD). TD mostly involves muscles in the face, but may also involve those in the limbs. You cannot control these movements, and they may not go away even after stopping the medications. There is no treatment for TD, but symptoms may lessen or disappear over time after stopping the medications. You may be more likely to develop TD if you are elderly, especially if you are a woman, or if you have diabetes. Your risk also increases the longer you take these medications and the more of each you take. As such, treatment with metoclopramide should generally be limited to 12 weeks. Let your doctor know promptly if you experience muscle spasm or movements that you can't stop or control, such as lip smacking, chewing, puckering, frowning or scowling, tongue thrusting, teeth clenching, jaw twitching, blinking, eye rolling, shaking or jerking of arms and legs, tremor, jitteriness, restlessness, pacing, and foot tapping. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate

fentaNYL metoclopramide

Applies to: droperidol / fentanyl and Metozolv ODT (metoclopramide)

Narcotic pain medications like fentaNYL may reduce the effects of metoclopramide. Contact your doctor if your symptoms worsen or your condition changes during treatment with these medications. Your doctor may be able to prescribe alternatives that do not interact. In addition, combining these medications may increase nervous systemic side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. You should avoid or limit the use of alcohol while being treated with these medications, and also avoid driving or operating hazardous machinery until you know how the medications affect you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug and food interactions

Major

fentaNYL food

Applies to: droperidol / fentanyl

Do not use alcohol or medications that contain alcohol while you are receiving treatment with fentaNYL. This may increase nervous system side effects such as drowsiness, dizziness, lightheadedness, difficulty concentrating, and impairment in thinking and judgment. In severe cases, low blood pressure, respiratory distress, fainting, coma, or even death may occur. You should also avoid consuming grapefruit and grapefruit juice, as this may increase the blood levels and effects of fentanyl. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. Do not use more than the recommended dose of fentaNYL, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.

Major

droPERidol food

Applies to: droperidol / fentanyl

Using droPERidol together with ethanol can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications, whether together or alone. In addition, you should let your doctor know if you experience signs of electrolyte disturbance such as weakness, tiredness, drowsiness, confusion, muscle pain, cramps, dizziness, nausea, or vomiting. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

metoclopramide food

Applies to: Metozolv ODT (metoclopramide)

Alcohol can increase the nervous system side effects of metoclopramide such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with metoclopramide. Do not use more than the recommended dose of metoclopramide, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.

Duplication

Antidopaminergic-like antiemetics

Therapeutic duplication

The recommended maximum number of medicines in the 'antidopaminergic-like antiemetics' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'antidopaminergic-like antiemetics' category:

  • droperidol/fentanyl
  • Metozolv ODT (metoclopramide)

Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.
