Type 2 diabetes drug metformin recalled due to contamination with possible carcinogen

Nostrum Laboratories Inc. announced Monday that it is voluntarily recalling its metformin HCl extended release tablets.

(CNN)Two lots of a widely used type 2 diabetes medication, metformin, are being recalled due to possible contamination with a potentially cancer-causing compound. Metformin is designed to lower glucose levels.

Nostrum Laboratories Inc., based in Kansas City, Missouri, announced Monday that it is voluntarily recalling its metformin HCl extended release tablets, USP 750 mg, according to a recall posted by the US Drug & Food Administration.
Testing revealed levels of nitrosamine, or NDMA, above acceptable limits in the recalled tablets.
    The chemical NDMA is considered a possible carcinogen by the US Environmental Protection Agency. It's an organic chemical used to make liquid rocket fuel and it can be a byproduct of manufacturing, including pharmaceutical manufacturing. It's also found in water and foods, including meats, dairy and vegetables.
      NDMA has also been found in certain blood pressure drugs and antacid.
