McNeil Consumer Healthcare, a division of Johnson & Johnson, recalled several hundred batches of many of its popular medicines, including Benadryl, Motrin, Rolaids, Simply Sleep, St. Joseph Aspirin and Tylenol, due to consumer complaints of a moldy smell upon opening. The alarming news for consumers, however, is that the recall came 20 months after complaints were logged. The Food and Drug Administration sent a warning letter to the company last week, noting the consumers have also reported temporary digestive problems like nausea, vomiting and stomach pain. McNeil released a statement Friday claiming chemicals used to treat wood pallets that transport and store product packaging were the source of the moldy smell in some products.
