Fluoxetine + Ibuprofen

MODERATE — Monitor Closely

FDA-documented interaction. 3-6x increased GI bleeding risk. Use acetaminophen when possible.

Evidence level: STRONG

What this interaction means

Prozac with ibuprofen significantly increases your risk of stomach and intestinal bleeding. Prozac reduces platelet clotting ability, and ibuprofen damages the stomach lining while also reducing clotting.

How it works (mechanism)

SSRI-mediated platelet dysfunction plus NSAID COX-1 inhibition and GI mucosal damage. 3-6x increased GI bleeding risk. FDA SSRI labels warn.

Practical advice

Use Tylenol instead of Advil/Motrin when possible. If you need regular ibuprofen, ask about stomach protection.

Timing

SSRIs reduce platelet serotonin uptake, increasing bleeding risk — adding an NSAID compounds this. Take Ibuprofen 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.

Symptoms to watch for

Stomach pain, dark stools, blood in stool, unusual bruising

What to tell your doctor

Acetaminophen preferred. PPI co-therapy if NSAID use is chronic. Risk is 3-6 fold for upper GI bleeding.

Safer alternatives

Discuss this combination with your prescriber. They may adjust timing, dosing, or switch to an alternative with fewer interaction risks. Never stop an antidepressant abruptly — taper under medical guidance.
