WASHINGTON — More than 40 over-the-counter infant's and children's liquid medications are being recalled in the United States and 11 other countries by the manufacturer because they don't meet quality standards.

McNeil Consumer Healthcare issued the recall for children's versions of Tylenol, Tylenol Plus, Motrin, Zyrtec and Benadryl after consulting with the Food and Drug Administration.

The company said in a statement yesterday that some of the products recalled may have a higher concentration of active ingredient than is specified on the bottle. Others may contain particles, while still others may contain inactive ingredients that do not meet internal testing requirements, the company said.

The recall was not undertaken because of any adverse effects, the company said.

But the company is advising consumers to stop giving the products to their children, as a precautionary measure.

The medicines were made and distributed in the U.S., and exported to Canada, the Dominican Republic, Dubai, Fiji, Guam, Guatemala, Jamaica, Puerto Rico, Panama, Trinidad and Tobago and Kuwait.
