MedWatch reports can signal a safety problem and lead to an FDA action to protect the public from harm, serious illness, or even death.

Here are a few of the most recent safety alerts prompted by reports received by FDA from health care professionals and their patients.

Recall: Tylenol Arthritis Pain Caplet, 100 Count Bottles

McNeil Consumer Healthcare expanded its recall to include all product lots of Tylenol Arthritis Pain Caplet, 100 count bottles, with the distinctive red EZ-open cap. In November 2009, McNeil recalled five lots of this product due to reports of an unusual moldy, musty, or mildew-like odor that was related to nausea, stomach pain, vomiting, and diarrhea.

The odor is caused by the presence of a compound believed to be the breakdown of a chemical used to treat wooden pallets that transport and store packaging materials.

The risk: The health effects of the compound believed to cause the symptoms have not been well studied. To date, all of the observed events reported were temporary and not serious.

• Stop using any Tylenol Arthritis Pain Caplet, 100 count bottles, with the distinctive red EZ-open cap.
• Contact the company, McNeil Consumer Healthcare, at 888-222-6036 or at, for instructions on how to get a refund or replacement, and how to return or dispose of the product.
