Summary
Rasagiline labeling warns against meperidine because of reports of serious, sometimes fatal serotonin syndrome-like reactions with MAO inhibitors. Symptoms can include agitation, hyperthermia, rigidity and autonomic instability.
What this interaction means in plain words
Meperidine 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.
Meperidine belongs to Musculoskeletal; Rasagiline belongs to Central Nervous System.
Why it happens
MAO inhibition combined with meperidine's serotonin reuptake inhibition increases serotonergic activity.
What to do
Avoid the combination and allow an adequate washout interval, generally at least 14 days after rasagiline. Use a different analgesic.
