Last updated

Summary
Combining an MAOI with an opioid like buprenorphine can cause serotonin syndrome, and may also produce opioid toxicity with respiratory depression and coma. Because the long-acting injection cannot be quickly removed, any reaction can be prolonged.
What this interaction means in plain words
Buprenorphine long-acting and Tranylcypromine 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 excess from MAO inhibition combined with opioid effects, plus possible enhancement of opioid CNS and respiratory depression.
What to do
Do not use the long-acting injection in patients taking an MAOI or within 14 days of stopping one. Choose a non-serotonergic alternative or wait the washout period.
