The FDA today announced a recall of about 11 million bottles of store-brand acetaminophen 500-milligram caplets
Those caplets are over-the-counter drugs for pain relief and fever reduction. They're sold by about 130 companies, including Wal-Mart, CVS, and other drug stores, grocery stores, and wholesalers.
The recall is due to "small metal fragments found in a small number of these caplets," states an FDA news release.
The fragments range in size from "microdots" to 8-millimeter pieces of wire, according to the FDA.
The FDA and the caplets' maker, Perrigo Company of Allegan, Mich., are investigating how those metal fragments got into the caplets.
So far, no illnesses, injuries, or consumer complaints have been reported to the FDA or Perrigo, according to the FDA.
