Why aspirin can cause stomach pain
Aspirin (an NSAID) can irritate the stomach lining and reduce protective stomach chemicals (prostaglandins). That can lead to inflammation, gastritis, and sometimes stomach ulcers or bleeding, which feel like burning or aching pain in the upper belly. The risk is higher with higher doses, taking aspirin on an empty stomach, alcohol use, smoking, age over 60, and a history of ulcers or reflux.
What the pain might feel like, and when it suggests an ulcer or bleeding
Stomach pain from aspirin often shows up as burning or gnawing discomfort in the upper abdomen. If aspirin is causing an ulcer or irritation severe enough to bleed, symptoms may include:
- Black, tarry stools or blood in stool
- Vomiting blood or vomit that looks like coffee grounds
- Fainting, dizziness, or weakness from blood loss
- Worsening pain that does not improve
When to stop aspirin and get urgent care
Seek urgent care or emergency help if you have any signs of GI bleeding (black/tarry stools, vomiting blood/coffee-ground material) or severe/worsening abdominal pain. If you only have mild discomfort, contact a clinician promptly for advice on whether to stop and what to switch to.
What you can do right now to reduce stomach irritation
If your clinician says it’s safe to continue aspirin (for example, for heart protection), people often reduce stomach irritation by taking it with food and avoiding alcohol. Do not “double up” on pain medicines to mask symptoms. Also avoid other NSAIDs (like ibuprofen or naproxen) unless your clinician specifically tells you to—combining NSAIDs increases stomach injury risk.
If you are not supposed to keep taking aspirin (for example, you’re using it for pain/fever and not a prescribed blood-thinner plan), stopping may be the most direct step. A clinician can suggest an alternative (sometimes acetaminophen is used for pain, since it is not an NSAID).
What medications might be used to treat aspirin-related stomach pain
Clinicians may use stomach-protecting medicines such as proton pump inhibitors (PPIs) or H2 blockers if aspirin is needed, especially in people with ulcer risk. Antacids may help short-term symptoms but don’t address the deeper cause (NSAID-related injury). The right option depends on your symptoms and risk factors.
Can you switch from aspirin to something gentler?
It depends on why you’re taking aspirin. If it’s for pain, many people use alternatives that don’t irritate the stomach the same way as NSAIDs. If it’s for preventing blood clots (for example, after heart attack or stroke), stopping can be dangerous—switching or adding stomach protection should be guided by your prescriber.
Patient questions that often come up
“Is enteric-coated aspirin safer?”
Enteric-coated aspirin can be less irritating for some people, but it still can cause stomach injury and bleeding. If you’re already having stomach pain, coating may not be enough.
“Does taking it with food help?”
Yes, taking aspirin with food usually reduces irritation. It’s still not a guarantee against ulcers.
“How long after starting aspirin would symptoms happen?”
Stomach irritation can start soon after taking aspirin, but ulcer-related symptoms can develop over time. What matters most is whether symptoms are severe or suggest bleeding.
