What does aspirin do in the body that could lower inflammation?
Aspirin is a nonsteroidal anti-inflammatory drug (NSAID). It works by blocking enzymes involved in making prostaglandins—chemical signals that promote pain, fever, and inflammation. By reducing prostaglandin production, aspirin can lower inflammatory activity in tissues.
Does aspirin reduce inflammation from injuries, fever, or long-term conditions?
Yes for acute symptoms: aspirin is commonly used to reduce inflammation-related pain and swelling associated with minor injuries and inflammatory irritation. It can also reduce fever, which is driven by inflammatory signaling in the body.
For long-term inflammatory diseases, whether aspirin helps depends on the condition and the dose used. Aspirin is not a universal treatment for chronic inflammatory disorders, and its use for long-term inflammation is more limited than for pain/fever relief.
How is aspirin different from other anti-inflammatory medicines?
Because aspirin specifically inhibits prostaglandin-making enzymes, its anti-inflammatory effects overlap with other NSAIDs (like ibuprofen and naproxen). Different NSAIDs can vary in strength, dosing schedules, and side-effect profiles, but the core inflammatory pathway they target is similar.
What side effects can happen if you use aspirin to treat inflammation?
Aspirin can increase bleeding risk and irritate the stomach lining. People can also be more likely to have stomach ulcers or GI bleeding, especially at higher doses or with frequent use. It can also worsen symptoms in some people who have aspirin-sensitive asthma.
When should you avoid aspirin?
Avoid aspirin unless a clinician advises it if you have:
- A history of stomach ulcers or GI bleeding
- A bleeding disorder or you take blood thinners
- Aspirin-sensitive asthma or prior reactions to aspirin/NSAIDs
- Viral illness in children or teens (risk of Reye's syndrome)
If you’re using aspirin specifically to “reduce inflammation,” it’s also worth checking whether there’s a safer or more effective option for your condition (for example, targeted anti-inflammatory treatment rather than general pain/fever relief).
