Diabetes Medication Recall 2021: Another Metformin Drug Recalled Over Possible Cancer Fears

Viona Pharmaceuticals has recalled two lots of the diabetes medication Metformin — the latest in a string of recalls for the drug — over concerns of higher than acceptable levels of a possible cancer-causing ingredient.

The recalled medication may contain Nitrosodimethylamine (NDMA) impurities in levels that are above the acceptable daily limits set by the Food and Drug Administration. NDMA is classified as a probable human carcinogen, a substance that could cause cancer.

Two lots of Metformin Hydrochloride Extended-Release tablets in 750 mg dosages were voluntarily recalled by Viona Pharmaceuticals. The Metformin drug is used to manage blood glucose in adults with Type 2 diabetes.

The affected medication was manufactured by Cadila Healthcare Limited of Ahmedabad, India, in November 2019 and distributed by Viona nationwide.

The recalled Metformin was packaged in 100-count bottles with an NDC number of 72578-036-01. The batch number for the diabetes drug is M915601, and the expiration date is October 2021.

The tablets can be identified as white to off-white, capsule-shaped, uncoated tablets that are debossed with a “Z,” “C” on one side, and “20” on the other side.

Patients are advised to continue taking the affected medication and contact their physician for advice regarding an alternative treatment plan. The FDA said that it could be dangerous for patients with this serious health condition to stop taking Metformin without first talking to their healthcare provider.

Questions about the recall can be directed to Viona’s processor, Eversana Life Science Services, by phone at 1-888-304-5022, Option 1, Monday through Friday from 8 a.m. to 7 pm. CT.

To report an adverse event from the medication or a quality issue, consumers can contact Viona Pharmaceuticals at 1-888-304-5011, Monday through Friday, from 8:30 a.m. to 5:30 p.m. ET.

Viona said it has not received any reports of adverse events related to the recall of the medication. Consumers that experience any issues related to the recalled diabetes medication should contact their healthcare provider.
