Summary
SSRIs reduce platelet serotonin and salicylates irritate the gastric lining and inhibit platelet function, so together they increase the risk of gastrointestinal bleeding. The risk is higher in older adults and those with prior ulcers.
What this interaction means in plain words
Fluoxetine and Salicylates 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.
Why it happens
Additive effects on hemostasis from SSRI-induced platelet serotonin depletion and salicylate-induced platelet and mucosal effects.
What to do
Monitor for GI bleeding and bruising and consider a proton pump inhibitor in high-risk patients. Use the lowest effective salicylate dose.
What to ask your pharmacist
