Johnson & Johnson is pulling more product off warehouse and store shelves, this time for its heartburn medicines. The “wholesale and retail level” recalls include 12 million bottles of over-the-counter Mylanta and almost 85,000 bottles of AlternaGel liquid antacid. The medicines were found to contain small amounts of alcohol from flavoring agents that was not noted on the product’s packaging. Though Johnson & Johnson has issued the recall, consumers are being told they can still use the medicines, which contain concentrations of less than 1 percent alcohol.

The recalled lots of Mylanta and AlternaGel were produced at Johnson & Johnson’s McNeil manufacturing plant in Fort Washington, Pennsylvania. The plant was shut down earlier this year for substandard quality control practices, which spurred a major recall of Tylenol, Benadryl and Motrin. The company is currently under investigation by a Congressional committee.

Johnson & Johnson has had to recall more than 200 million bottles of OTC medicines over the past year, including both adult and pediatric varieties, because of problems ranging from inadequate manufacturing practices and foul-smelling bottles to wrong ingredient levels and metal particles in the pills. While no serious injuries were reported, some consumers experienced nausea, vomiting and gastrointestinal distress.

The reputation of Johnson & Johnson, the world’s largest maker of health care products, has suffered as more and more of the company’s brand name products have been recalled. U.S. sales of the company’s consumer products dropped 25 percent in the third quarter because the medicines were either unavailable or consumers opted to use other brands or generic equivalents.
