The maker of Rolaids antacid tablets has announced a voluntary recall of some of the tablets in Canada.
The Canadian action is part of a wider international voluntary recall of certain lots of several over-the-counter products made by Johnson & Johnson.
The products are being recalled after reports some lots of medications had a mouldy smell that induced nausea in some consumers.
McNeil Consumers Healthcare, a division of Johnson & Johnson, says in Canada the recall only relates to Rolaids that come in bottles of 100 and 150 tablets.
The company says the move is being taken as a precaution; the odour has been linked to wood pallets used in the transport and storage of packing materials for the products.
The larger recall, which extends to the Americas, the United Arab Emirates and Fiji, involves a range of products including batches of Tylenol caplets and gel tabs, arthritis treatments, rapid-release and extended-relief Tylenol and chewable extra-strength Rolaids.
