FORT WASHINGTON, Pa. — McNeil Consumer Healthcare is recalling 21 lots of over-the-counter medicines under the Benadryl, Tylenol, Children’s Tylenol and Motrin banners in a follow-up to a January recall.

McNeil, which announced the additional recall Thursday, said the move is precautionary and involves products sold in the United States, Fiji, Guatemala, Dominican Republic, Puerto Rico, Trinidad and Tobago, and Jamaica.

Items in the latest recall include certain lots of Benadryl Allergy Ultratab tablets; Children’s Tylenol Meltaways; Motrin IB caplets and tablets; Tylenol Extra Strength caplets, EZ Tablets and Cool Caplets; Tylenol Day & Night Value Pack; Tylenol Extra Strength Rapid Release gelcaps; and Tylenol PM caplets, geltabs and rapid-release gelcaps.

This action is another follow-up to a product recall that McNeil originally announced on Jan. 15, 2010, which was initiated following consumer complaints of a musty or moldy odor that has been linked to the presence of trace amounts of a chemical called 2,4,6-tribromoanisole (TBA). The initial action was followed up in June with a recall of certain lots of Benadryl and Tylenol products.

According to the company, the additional lots are being added to the list of recalled products as a precautionary measure after a continuing internal review determined that some packaging materials used in the lots had been shipped and stored on the same type of wooden pallet that was tied to the presence of TBA in earlier recalled lots. All lots involved in the recall were produced before the Jan. 15 recall, after which McNeil stopped accepting shipments of materials from its suppliers on that type of pallet.

McNeil said the risk of serious adverse medical events from the recall is remote, and the action is being conducted with the knowledge of the Food and Drug Administration.

Consumers who purchased product from the lots included in the recall should stop using the product and contact McNeil Consumer Healthcare for instructions on a refund or replacement. More information on the recalled products can be found at www.mcneilproductrecall.com.
