Summary
Both drugs increase serotonergic activity, so combined use raises the risk of serotonin syndrome, which can present with agitation, tremor, hyperthermia and autonomic instability. Both can also lower seizure threshold, and citalopram's CYP2D6 effects are weak.
What this interaction means in plain words
Citalopram 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.
Citalopram belongs to Central Nervous System; Tramadol belongs to Musculoskeletal.
Why it happens
Additive serotonergic activity through SSRI action and tramadol serotonin reuptake inhibition.
What to do
Use the lowest effective tramadol dose and monitor for serotonin syndrome and seizures, especially at initiation and dose increases. Consider a non-serotonergic analgesic where possible.
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?
