The U.S. Food and Drug Administration (FDA) has notified health care professionals and patients that nearly half a million single-use ReliOn syringes (manufactured by Covidien Ltd.) are being recalled due to possible mislabeling.

According to the FDA, the use of these syringes may lead diabetic patients to receive an insulin overdose of as much as 2.5 times of the intended dose. Insulin overdose can cause serious health consequences, including dangerously low blood sugar and even death. The possibly mislabeled syringes were sold in Wal-Mart stores and Sam's Clubs from Aug. 1 till Oct. 8 of this year. Customers who purchased ReliOn syringes from lot number 813900 are instructed to return them to their local Wal-Mart or Sam's Club pharmacy, where they will be provided with a replacement product.
