J&J's McNeil unit recalls Infants' Tylenol

McNeil is recalling more than half a million bottles of Infants' Tylenol because of problems with the dosing syringe.

NEW YORK (CNNMoney) -- The healthcare company McNeil is recalling more than half a million bottles of Infants' Tylenol because of consumer complaints about the difficulties of using the dosing system.

McNeil is recalling about 574,000 bottles after receiving a "small number" of complaints regarding the so-called "dosing syringe" of the orally-administered over-the-counter painkiller. The company said that in some cases the "flow restrictor was pushed into the bottle when inserting the syringe."

The recall applies to one-ounce bottles of grape-flavored Infants' Tylenol Oral Suspension.

The company said there have been "no adverse events" from the problem and that "the risk of series adverse medical event is remote."

Drug shortages at all-time high

The company said that consumers can continue to use the product, despite the voluntary recall, so long as the flow restrictor remains in place at the top of the bottle.

McNeil, a subsidiary of Johnson & Johnson (JNJ, Fortune 500), has had numerous recalls in the recent past, especially with Tylenol.

The U.S. government took over three Tylenol plants last year for failure to comply with federally-mandated manufacturing procedures.
