Summary
Fentanyl causes respiratory depression and pancuronium paralyzes respiratory muscles, so together they increase the risk of hypoventilation if breathing is not supported. Intranasal fentanyl is usually used outside the operating theater, so this concern is mainly relevant in unventilated patients.
What this interaction means in plain words
Fentanyl intranasal and Pancuronium can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Central opioid respiratory depression adds to neuromuscular blockade of respiratory muscles.
What to do
Give only with airway control and ventilatory support. Monitor respiratory rate, oxygenation and neuromuscular recovery.
What to ask your pharmacist

- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
