In consultation with the U.S. Food and Drug Administration (FDA), all Tylenol Arthritis Pain Caplet 100 count bottles with a red “EZ-OPEN CAP” have been recalled due to consumer reports of an “unusual moldy, musty, or mildew-like odor” that has associated with nausea, stomach pain, vomiting and diarrhea.

According to the FDA, the smell appears to be being caused by the presence of trace amounts of a chemical called 2,4,6-tribromoanisole – a chemical used to treat wooden pallets that transport and store packaging materials. Although the health effects of the compound have not been well studied, it is believed that the effects are temporary and not of serious nature.

Consumers who purchased the product have been instructed to contact the manufacturer -- Mcneil Consumer Healthcare, at 1-888-222-6036 (Monday-Friday 8 a.m. to 8 p.m. Eastern Time, and Saturday-Sunday 9 a.m. to 5 p.m. Eastern Time) or log on to the internet at www.tylenol.com. The FDA has also instructed consumers who have medical concerns or questions to contact their healthcare providers and to report adverse reactions to the FDA’s MedWatch Program by fax at 1-800-FDA-0178, by mail at MedWatch, FDA, 5600 Fishers Lane, Rockville, MD 20852-9787, or on the MedWatch website at www.fda.gov/medwatch.
