Can ibuprofen hurt your stomach?
Last updated September 3, 2026.
Yes - MedlinePlus is blunt: ibuprofen can cause ulcers, bleeding, or holes in the stomach and intestine, at any time, sometimes without warning. The pain-blocking mechanism also shuts down the stomach's protective mucus. Risk climbs with high doses, long use, age over 65, past ulcers, smoking, regular alcohol, and combining with blood thinners, aspirin, other NSAIDs, steroids, or SSRIs. Safe use: lowest effective dose, shortest course, with food or milk, no alcohol, never stacked with naproxen or aspirin. Stop-and-call signs: new stomach pain or heartburn, bloody or coffee-ground vomit, black tarry stools. Need weeks of daily relief? Ask about stomach protection or switching to acetaminophen.

What to do
- Take it with food or milk: and the lowest dose that works.
- Never stack NSAIDs: ibuprofen plus naproxen or aspirin multiplies risk.
- Know the bleeding signs: coffee-ground vomit, black tarry stools - call now.
- Long-term pain needs a plan: protection or a different drug, not endurance.
