Blood thinner Plavix warning may not be necessary

December 28, 2011 12:07:04 PM PST
A new analysis of the popular blood thinner Plavix contradicts the 2010 black box warning on the label mandated by the Food and Drug Administration.

The Journal of the American Medical Association says Plavix is a safe and effective medication for patients. The warning cautions the drug has diminished effectiveness in poor metabolizers and might lead to an increase in cardiovascular events such as heart disease or bleeding. But the new analysis suggests it's time to rethink the warning.
