The Tylenol recall has been expanding. When it first started in November 2009, it was limited to five specific lots. Now, the FDA is reporting that the recall includes all Tylenol Arthritis Pain 100 Count with [Red] EZ-Open Cap.
The defect at issue is that the pills feature a moldy, musty smell, and some users have complained of nausea, stomach pain, diarrhea, and/or vomiting. The source of that defect is the chemical 2,4,6-tribromoanisole (interestingly enough, also a component to some issues of cork taint in wine), which was used to treat wood pallets transporting and storing the packaging materials.
The Tylenol recall page has more information on refunds and returns. They’ve done a solid job of advertising the recall in the media and on their websites. Good job to the manufacturer, McNeil Consumer Healthcare.
