Why is aspirin used?
Aspirin (such as Bayer or Bufferin) relieves pain and reduces fever and inflammation. It also prevents blood clots from forming in the arteries. Doctors sometimes recommend daily aspirin for people at high risk of heart attack or stroke.
What about side effects?
The most common side effect of aspirin is stomach upset or discomfort. Taking it with food may help. Aspirin can also cause headaches. Sometimes it can make you bleed or bruise more easily. Stop taking it and call a doctor if side effects don't go away within 4 hours.
