Americans should limit use of daily aspirin meant to prevent heart attack or stroke, task force says

But taking aspirin also can cause major bleeding that can be fatal, especially in older people, said Tseng, a professor in the Department of Family Medicine and Community Health at the University of Hawai’i John A. Burns School of Medicine. That’s why, in another noteworthy change, the task force is now saying that adults 60 or older shouldn’t start taking aspirin daily to lower the chances of a first heart attack or stroke, concluding that there is “no net benefit” in doing so.
