Summary

SSRIs combined with NSAIDs increase the risk of upper gastrointestinal bleeding well above that of either drug alone. The risk is higher in older adults and those with prior ulcer disease.

What this interaction means in plain words

Citalopram and Oxaprozin 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; Oxaprozin belongs to Musculoskeletal.

Evidence level: High

Why it happens

SSRIs deplete platelet serotonin and impair aggregation while NSAIDs impair platelet function and damage gastric mucosa, giving additive bleeding risk.

What to do

Avoid the combination where possible, or add a proton pump inhibitor and monitor for signs of GI bleeding such as melena or anemia.

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?
