Three Firms Recall Diabetes Drug


June 26, 2020

Apotex Inc., AvKARE Inc., and PD-Rx Pharmaceuticals Inc. are recalling metformin hydrochloride extended-release tablets after a US Food and Drug Administration (FDA) analysis identified an N-Nitrosodimethylamine (NDMA) impurity in the product that was above an acceptable level. The recalls are included in the June 24, 2020, FDA Enforcement Report. 

“Apotex was notified by the FDA that one lot of metformin hydrochloride extended-release tablets, USP, was tested and showed results for NDMA levels in excess of the acceptable daily intake limit and recommended recall of the one tested lot,” Apotex stated in a May 27, 2020, company announcement. “Apotex Corp has agreed to recall this lot, and out of an abundance of caution, the company is extending the recall to all lots of metformin hydrochloride extended-release tablets in the United States.” 

On May 27, 2020, Apotex voluntarily initiated its recall of all unexpired lots of metformin hydrochloride extended-release tablets, 500 mg, 100-count bottles (NDC 60505-260-1), distributed throughout in the United States.
