Viona Pharmaceuticals has recalled two lots of diabetes drug metformin HCl 750mg because the product was found to contain levels of human carcinogen nitrosodimethylamine (NDMA) impurities above acceptable daily limits. The product was manufactured by Cadila Healthcare (Ahmedabad, India) for U.S. distribution by Viona Pharmaceuticals, according to a [recall notice](https://www.fda.gov/safety/recalls-market-withdrawals-safety-alerts/viona-pharmaceuticals-inc-issues-voluntary-nationwide-recall-metformin-hcl-extended-release-tablets?ref=fdaweb.com).  

NDMA is a known environmental contaminant and is found in water and foods, including meats, dairy products, and vegetables. Patients taking medications from the affected lots are advised to continue taking them and contact their physician for advice on an alternative treatment, the notice says.
