Summary
Paroxetine strongly inhibits CYP2D6, reducing formation of the active metabolite O-desmethyltramadol and therefore analgesia, while parent tramadol rises. Both drugs are serotonergic, so the risk of serotonin syndrome and seizures is increased.
What this interaction means in plain words
Paroxetine and Tramadol can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Paroxetine belongs to Central Nervous System; Tramadol belongs to Musculoskeletal.
Why it happens
CYP2D6 inhibition by paroxetine and additive serotonergic activity.
What to do
Avoid the combination where possible and use a non-serotonergic analgesic that does not depend on CYP2D6 activation. If it must be used, monitor for serotonin toxicity, seizures and inadequate pain relief.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
- What early warning signs should I watch for, and what should I do if they appear?
