One of the implied promises of a brand name, especially when it comes to drugs, is you can expect higher quality, but maybe that doesn’t apply when it comes to McNeil products.The FDA says the plant that produced the recently recalled children’s Tylenol, Motrin, Zyrtec and Benadryl, was using raw materials that were contaminated with bacteria. The plant also lacked adequate quality-control procedures and was dirty. So far none of the recalled medicine has tested positive for bacterial contamination, but the FDA report suggests that the contaminated material was used to make the recalled lots. The plant has been shut down indefinitely.
