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

Our news partner, WZZM 13, says McNeil Consumer Healthcare 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. That restrictor has been pushed into the bottle in some cases when the syringe is inserted.

Here is a video on how to properly use the syringe and details on the recall:
