The musty smell has been linked to trace amounts of 2,4,6-tribromoanisole -- also known as TBA -- which is a residue of a fungicide used to treat the wooden pallets on which the bottles of the over-the-counter medicine are stored. The same chemical is responsible for the recall of millions of bottles of Tylenol and other Johnson and Johnson drugs since December 2009.
While not considered to be toxic, TBA can cause a foul odor and has been linked to temporary and non-serious gastrointestinal maladies, the U.S. Food and Drug Administration said."McNeil is taking this action following a small number of odor reports, including musty, moldy odor," the company said in a statement. Consumers who have medical questions are urged to call their doctor.
Consumers who bought the recalled Tylenol should stop using it and call McNeil at (888) 222-6036 weekdays between 8 a.m. to 8 p.m. EST for instructions about receiving either a refund or a product coupon.
