A Costco-brand cold and flu medicine has been pulled from shelves “due to potential foreign material contamination.”

A notice shared on the retail giant’s website says the recall of Kirkland Signature Severe Cold & Flu Plus Congestion involves item number #1729556 with specific lot code P140082, which was sold at select locations in the Midwest and southeast.

“Out of an abundance of caution, LNK has initiated a recall for the accidental release and shipment of a specific lot code that was rejected due to potential foreign material contamination,” the statement reads.

The impacted over-the-counter medicine was purchased by customers between Oct. 30 and Nov. 30, 2024. Consumers are told not to use any remaining product with the lot code and to return it to Costco for a full refund.
