On May 29, 2020, Amneal Pharmaceuticals, LLC. released a company announcement, published by the FDA, informing consumers of a voluntary nationwide recall of all lots of 500mg and 750mg metformin extended-release tablets. Metformin is commonly used to improve blood sugar control in the treatment of type 2 diabetes. The recall was initiated due to the detection of low levels of an impurity, known as N-Nitrosodimethylamine (NDMA), which is classified as a probable cancer-causing substance by the International Agency for Research on Cancer (IARC). Although Amneal has not received any reports of adverse events, they have arranged for the return of all recalled products. The FDA has also published recalls of metformin manufactured by other companies including Time-Cap Labs, Inc., Teva Pharmaceuticals, Marksans, and Apotex Corp. Patients have been advised to contact the manufacturer or their health care provider for further information.
