A Johnson & Johnson consumer health unit plagued by product recalls says it is pulling some versions of infant Tylenol off store shelves due to problems with a device that helps measure doses.

McNeil Consumer Healthcare says it is recalling about 574,000 bottles of a grape-flavored version of the liquid medicine, which was distributed nationally.

The medicine bottle comes with a syringe and has a protective cover, or flow restrictor, at the top to help measure the right dose. McNeil says that restrictor has been pushed into the bottle in some cases when the syringe is inserted.

McNeil is one of three business segments for J&J, which is based in New Brunswick, N.J. The consumer division has issued about two dozen recalls in more than two years.
