Recall of Tylenol, Motrin leads to investigation by FDA

The Food and Drug Administration is reportedly investigating reports of at least 775 serious side effects from drugs recalled by McNeil Consumer Healthcare, a division of Johnson & Johnson.

Included in those reports were 30 deaths, nearly all of which were not linked to McNeil's recall of Tylenol, Motrin and Benadryl drugs from Jan. 1, 2008 through April 30, 2010, according to a source close to the investigation, CNNMoney.com reports.

The FDA is also investigating reports of several hundred serious side effects or "adverse events," and seven deaths since April 30, when McNeil recalled 50 children's versions of these non-prescription medicines because of serious quality and safety concerns, according to the CNN report.

Adverse events, which the FDA describes as complaints of a serious side effect associated with the use of a medical product, may include death, hospitalization, disability and other health complications.
