Common Aspirin Side Effects
Aspirin, an NSAID, often causes stomach upset, heartburn, nausea, or bleeding risks like easy bruising and gastrointestinal ulcers. Less common issues include allergic reactions (hives, swelling), tinnitus, or kidney strain in high doses or long-term use.[1][2]
Reducing Stomach and GI Issues
Take aspirin with food or milk to buffer stomach acid. Use enteric-coated versions that dissolve in the intestine, not the stomach. Antacids like calcium carbonate or H2 blockers (famotidine) can help mild heartburn; proton pump inhibitors (PPIs) like omeprazole protect against ulcers for those at high risk, such as older adults or long-term users.[1][3]
Handling Bleeding Risks
Avoid alcohol, which worsens bleeding. Stop aspirin 7-10 days before surgery or dental work unless a doctor advises otherwise. Monitor for black stools, blood in vomit, or unusual bleeding—seek immediate care. Low-dose aspirin (81 mg) for heart protection carries lower risk than higher doses.[2][4]
Managing Allergic Reactions or Ringing in Ears
For mild allergies (rash, itching), switch to acetaminophen if possible. Severe reactions (difficulty breathing, swelling) require emergency epinephrine and avoidance forever. Tinnitus from overdose often resolves by stopping aspirin and staying hydrated; persistent cases need medical evaluation.[1][5]
When to See a Doctor
Contact a provider for severe pain, persistent nausea, blood in stool/urine, chest pain, or swelling. Those with ulcers, asthma, kidney disease, or on blood thinners need closer monitoring or alternatives.[2][3]
Lifestyle Adjustments and Prevention
Stay hydrated, limit dose to the lowest effective amount (e.g., 325 mg every 4-6 hours max for pain), and don't exceed 4 g daily. Combine with rest for pain relief. Track symptoms in a log for doctor visits.[1][4]
Alternatives if Side Effects Persist
Acetaminophen (Tylenol) for pain/fever without GI bleed risk. Ibuprofen or naproxen for inflammation but similar stomach risks—use cautiously. Topical NSAIDs or non-drug options like physical therapy for chronic pain.[3][5]
