No documented interaction between Fluoxetine and Aspirin. Your pharmacist checks for interactions every time you fill a prescription. If you experience any new symptoms after starting Aspirin, let your doctor know — they can help determine if it's related to your medication combination.

Timing

SSRIs reduce platelet serotonin uptake, increasing bleeding risk — adding an NSAID compounds this. Take Aspirin with food. Consider using the lowest NSAID dose for the shortest duration. Your prescriber may recommend a gastroprotective agent (PPI or H2 blocker) if long-term use of both is needed.

Risk factors

Higher risk for: elderly, those on multiple serotonergic drugs, people with liver impairment, CYP2D6 poor metabolizers, recent dose changes, or concurrent use of MAOIs or triptans.

Watch for: stomach pain, heartburn, nausea, black or bloody stools, decreased urination, ankle swelling, unusual weight gain (fluid retention), or elevated blood pressure. When to seek emergency help: Vomiting blood or material resembling coffee grounds, severe abdominal pain, chest pain, sudden shortness of breath, signs of allergic reaction (hives, facial swelling, difficulty breathing), or very dark urine with reduced output.

What to tell your doctor

No urgent need to discuss, but always keep your doctor informed of your full supplement and medication list. An up-to-date list helps them make the best treatment decisions.
