WASHINGTON (AP) - Food and Drug Administration documents obtained by the Associated Press show Johnson & Johnson learned of problems with the potency of its Motrin formula in 2008, but did not recall the product until July the following year.
House lawmakers are investigating J&J after last month's recall of more than 40 varieties of children's medicine, some which contained tiny particles of metal.
That recall was the latest in a series that threaten to tarnish J&J brands like Tylenol and Benadryl.
Lawmakers plan to question a J&J executive Thursday about the latest problems as well as a 2009 recall.
The FDA documents show J&J learned of problems with some Motrin formulas in November 2008, but did not recall them until being prodded by the FDA in July 2009.
