Several nonprescription cold medicines are being pulled from store shelves after manufacturer Wyeth this week started a voluntary recall and replacement program at retail outlets nationwide.

The products are being removed because they come with a dosing cup that does not mark the half-teaspoon level recommended for children aged 2 through 5 years old, according to Wyeth Consumer Healthcare, a division of the Madison, N.J.-based drugmaker.

"There's nothing wrong with the products," said Wyeth spokesman Doug Petkus.

The products being recalled and replaced are: Robitussin Cough DM, Robitussin Cough & Cold CF, Robitussin Cough & Congestion, Robitussin Head & Chest Congestion PE, Robitussin Cough Sugar Free DM and Children's Dimetapp Cough & Chest Congestion.

The company is recommending that consumers with children in the 2 through 5 age group not use the medicines until replacement products with a new dosage cup are available. That will probably begin in early November, and the new boxes will be marked to indicate the replacement.

"It probably will take a couple months," Petkus said.

He said there are several million packages of those products in circulation, but there is no reason for consumers to seek a refund. No injuries related to the issue have been reported, Petkus said.
