Lawmakers have scheduled a hearing Thursday to look into the recall of popular pediatric medicines by drugmaker McNeil Consumer Healthcare, which has initiated four recalls of its products in the past seven months.
The recalls include popular over-the-counter drugs such as Tylenol, Motrin and Benadryl.
Fifty children's versions of these nonprescription medicines were also recalled on May 1 because of quality and safety concerns.
McNeil has maintained that its recall of the children's drugs was not "undertaken on the basis of adverse medical events" but as a precautionary measure.
Adverse event reports are consumer complaints of a serious side effect associated with the use of a medical product, according to the FDA.
Adverse events could include death, hospitalization, disability and other health complications.
Following the pediatric medicine recall, Johnson and Johnson suspended production at McNeil's facility in Fort Washington, Pennsylvania that manufactured the children's drugs.
Among those testifying will be Colleen Goggins, the worldwide chairman of Johnson and Johnson, of which McNeil is a division.
The House Committee on Oversight and Government Reform also invited Johnson and Johnson Chief Executive William Weldon, but he declined to attend because of health reasons.
A panel of Food and Drug Administration officials will also be at the hearing.
