Summary

Combining ketorolac with an SSRI substantially increases the risk of gastrointestinal and other bleeding. Ketorolac carries a boxed warning for bleeding risk, making this combination particularly undesirable.

What this interaction means in plain words

Citalopram and Ketorolac 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; Ketorolac belongs to Musculoskeletal.

Evidence level: High

Why it happens

SSRIs deplete platelet serotonin and impair platelet aggregation while ketorolac inhibits platelet COX-1 and damages gastric mucosa, producing additive bleeding risk.

What to do

Avoid the combination where possible, or limit ketorolac to a very short course. Consider gastroprotection with a proton pump inhibitor and monitor for signs of bleeding.

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?
