Summary
Both drugs enhance serotonergic neurotransmission, so combining them can lead to serotonin syndrome, presenting with agitation, tremor, hyperreflexia, hyperthermia and diarrhea. Additive sedation and a lowered seizure threshold are also possible.
What this interaction means in plain words
Tramadol and Trazodone 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.
Tramadol belongs to Musculoskeletal; Trazodone belongs to Central Nervous System.
Why it happens
Additive serotonergic effects (tramadol reuptake inhibition and release; trazodone serotonin reuptake inhibition and receptor modulation) plus additive CNS depression.
What to do
Use the lowest effective doses and educate the patient on serotonin syndrome symptoms. Stop both drugs and treat if symptoms appear; consider a non-serotonergic analgesic.
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?
