PARSIPPANY, N.J. — Reckitt Benckiser (RB) has recalled certain lots of liquid bottles of its over-the-counter Mucinex Fast-Max cough/cold medicines because of a labeling discrepancy.

RB said the voluntary recall, announced this week, stemmed from a confirmed report by a retailer. The issue involves specific lots of Mucinex Fast-Max Cold & Sinus, Severe Congestion & Cough and Cold, Flu & Sore Throat liquid medicines — including combo packs — that correctly label the product on the front of the bottle and list all active ingredients but may not have the correct corresponding drug facts label on the back.

The company noted that mislabeling could cause consumers to be unaware of side effects and/or risks associated with the ingestion of certain product ingredients, which include acetaminophen, dextromethorphan, guaifenesin, phenylephrine and/or diphenhydramine.

RB said it’s notifying its distributors and customers by direct correspondence. As a precautionary measure, the company also is asking consumers to dispose of any unused product according to the following recommended guidlines: Mix liquid medicines with an unpalatable substance such as kitty litter or used coffee grounds, place the mixture in a container such as a sealed plastic bag, and throw the container in their household trash.
