Another manufacturer has recalled Metformin extended release tablets, which is prescribed to people suffering from type 2 diabetes.

Amneal Pharmaceuticals of Bridgewater, New Jersey, is recalling all lots of Metformin Hydrochloride Extended Release Tablets, USP, 500 mg and 750 mg.

Amneal was notified by the U.S.Food and Drug Administration that testing of seven lots of Metformin tablets showed N-Nitrosodimethylamine (NDMA) amounts above acceptable levels. The FDA recommended the recall of the seven tested lots. Amneal decided to extend the recall to all lots of Metformin extended release tablets. To date, the manufacturer has not received any reports of adverse events that have been confirmed to be directly related to this recall.

Amneal’s Metformin Hydrochloride Immediate Release Tablets, USP, are not affected by this recall.

      Call your pharmacist to see if your medication has been recalled. You can also check the FDA website for recalls.
