The cRc of Chicago has sent out the following Alert.
October 27, 2010
Children's Liquid Tylenol and Motrin produced in the USA were known to use kosher glycerin, but have been off the market for a few months. Liquid Tylenol is now being imported from a Canadian plant, which informed the cRc that their product contains non-kosher animal glycerin. Accordingly, the product is not kosher and we recommend you consult with your Rabbi to find out if you may use the product.
