CHICAGO - A daily dose of the "wonder drug" may be doing you more harm than good.

The British Heart Foundation is urging people who don't have health problems not to take Aspirin daily. Experts say the drug increases the chances of major bleeding--in the brain, stomach and elsewhere in the body.

Asprin is taken by millions of people regularly as a way to prevent heart attacks, but researchers from Scotland found that the drug taken by people who have no outward symptoms of heart disease did not reduce the risk of a heart attack, compared to those on a placebo.
