Viona Recalls 33 Lots of Diabetes Drug Due to Possible NMDA Contamination
Viona Pharmaceuticas is recalling 33 lots of metformin hydrochloride extended-release tablets, USP 750 mg, because of potential contamination by N-nitrosodimethylamine (NDMA), a likely carcinogen.
Metformin is prescribed for use along with diet and exercise to control high blood sugar in adults with type 2 diabetes mellitus. The lots in question, with expiration dates ranging from June 2022 to March 2023, were manufactured by India’s Cadila Healthcare for distribution in the U.S. by Viona.
The FDA warned that patients shouldn’t discontinue taking metformin without first consulting with a doctor because it could be dangerous for people with diabetes to stop their medication.
