McNeil Consumer Healthcare is recalling all 100-count bottles of its Arthritis Pain caplets after reports of a foul smell that has led to nausea, stomach pain and diarrhea.

The company describes the smell as moldy, musty or mildewy and said consumers have complained it about it leading to a variety of gastrointestinal issues. McNeil, a division of Johnson and Johnson, said in a written statement that it believes the odor is due to the breakdown of a chemical used to treat wooden pallets that transport and store packaging materials.

McNeil told the U.S. Food and Drug Administration that effects of the chemical "were temporary and non-serious."

A limited number of bottles were recalled in November, but the company expanded it to all 100-count "EZ-Open" bottles. The company said it expects to come out with a replacement line of the over-the-counter pills in January.

If you have one of the recalled bottles, you should stop using it and contact McNeil to find out how to get a refund or replacement bottle. A list of the lot numbers being recalled can be found here.
