Nearly one-third of FDA-approved drugs have problems, a new study finds.
The federal government approved 222 therapeutic drugs in a nine-year span from 2001-10 -- and 71 of the drugs triggered medical events with the people who took them.
It's one reason why manufacturers have added warnings for at least 61 drugs.
The findings appear in the Journal of the American Medical Association.
In a previous study, Yale University researchers had found that there’s a wide variation in how much testing drugs get before the FDA approves them.
The Yale study found that some drugs are fast-tracked to make them available sooner to the public -- but the speed means they're shortcutting the usual testing.
