What side effects do people commonly get from aspirin?
Common side effects of aspirin are mainly related to the stomach, because aspirin can irritate the lining of the GI tract. Reported common effects include:
- Stomach irritation or burning (heartburn)
- Nausea and sometimes vomiting
- Stomach pain or discomfort
- Indigestion
- Increased risk of bleeding in the stomach or intestines (which can range from mild to serious) [1]
What are the more serious aspirin reactions to watch for?
Some side effects are less common but more dangerous. Stop aspirin and seek urgent care if you notice:
- Signs of gastrointestinal bleeding: vomiting blood or material that looks like coffee grounds, black/tarry stools, or blood in stool [1]
- Allergic reactions: hives, swelling of the face/lips, wheezing, trouble breathing [1]
- Severe or persistent symptoms such as intense stomach pain, fainting, or weakness from blood loss [1]
Can aspirin cause breathing problems in some people?
Yes. Aspirin can trigger bronchospasm (tightening of the airways) in some people, especially those with aspirin-sensitive asthma. Possible symptoms include wheezing, shortness of breath, or worsening asthma after taking aspirin [1].
Who is more likely to have side effects?
Risk is higher if you:
- Have a history of stomach ulcers or GI bleeding
- Take other medicines that increase bleeding risk (such as other NSAIDs, blood thinners, or some antiplatelet drugs)
- Use high doses of aspirin or take it frequently
- Have asthma or prior aspirin sensitivity [1]
How do side effects differ between low-dose and higher-dose aspirin?
Low-dose aspirin (often used for heart protection) still can irritate the stomach and increase bleeding risk, though the types of side effects are similar. Dose and overall risk factors (like prior ulcers, age, and other medications) are key determinants of how likely bleeding or irritation becomes [1].
