Why Aspirin Isn't Tied to a Single Condition
Aspirin treats pain, fever, and inflammation from conditions like headaches, arthritis, muscle aches, toothaches, colds, and menstrual cramps. It also prevents blood clots in people at risk for heart attacks or strokes.[1]
How Does Aspirin Work for Pain and Inflammation?
It blocks enzymes (COX-1 and COX-2) that produce prostaglandins, chemicals causing pain and swelling. Effects start in 30 minutes for pain relief, lasting 4-6 hours.[1][2]
When Is Aspirin Used for Heart Health?
Low-dose aspirin (81 mg) thins blood by stopping platelets from clumping, cutting heart attack risk by 20-30% in high-risk patients. Doctors recommend it for those with prior events or multiple risk factors like diabetes.[1][3]
What About Stroke Prevention?
It reduces ischemic stroke risk (clot-caused) by 22%, but raises bleeding stroke risk, so it's not for everyone. Guidelines limit it to specific groups.[3]
Why Avoid Aspirin in Certain Cases?
Kids under 16 risk Reye's syndrome with viral infections. It causes stomach bleeding, ulcers, or allergic reactions in some. Not for uncontrolled high blood pressure or bleeding disorders.[1][2]
How Does Aspirin Compare to Ibuprofen or Acetaminophen?
Aspirin matches ibuprofen for inflammation but lasts longer; acetaminophen beats it for fever without stomach risks. Aspirin stands out for heart protection.[2]
