Summary
MAO inhibitors have been associated with severe and unpredictable reactions to opioids, including serotonin syndrome and profound CNS or respiratory depression. Rapid transmucosal absorption can make onset abrupt.
What this interaction means in plain words
Fentanyl transmucosal and Rasagiline are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Why it happens
Serotonergic effects of fentanyl combined with MAO inhibition may cause serotonin toxicity, and an additional poorly defined potentiation of opioid effect has been described.
What to do
Avoid fentanyl during and for 14 days after MAO inhibitor therapy. Choose an alternative breakthrough pain strategy.
