In 2010, consumer complaints of an unusual odor led McNeil-PPC (the division of Johnson and Johnson that makes Tylenol) to recall some forms of Tylenol and other drugs. The company determined the odor was due to trace amounts of 2,4,6-tribromoanisole, a chemical applied to treat wood pallets, reports CNN.
The company first received customer complaints of an unusual odor along with nausea, stomach pain, vomiting and diarrhea in early 2008, leading to two recalls of some Tylenol products in November and December of 2009. The 2010 recall, resulting from similar complaints, included 500 lots of children's Tylenol grape meltaway tablets, extra-strength Tylenol, extra-strength Tylenol rapid-release gelcaps, extra-strength Tylenol PM geltabs and other over-the-counter drugs manufactured by McNeil PPC. This recall included shipments to the Americas, the United Arab Emirates and Fiji, as reported by CNN.
