Summary

Trazodone has serotonergic activity that may impair platelet function, and with ketorolac this can raise the risk of gastrointestinal and other bleeding. The risk is lower than with potent SSRIs but is still relevant with ketorolac.

What this interaction means in plain words

Ketorolac and Trazodone can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Ketorolac belongs to Musculoskeletal; Trazodone belongs to Central Nervous System.

Evidence level: Moderate

Why it happens

Reduced platelet serotonin uptake adds to NSAID inhibition of platelet function and gastric mucosal injury.

What to do

Limit ketorolac to a short course, consider gastroprotection in patients at risk, and monitor for bleeding signs.
