One of the manufacturers of a Type 2 diabetes drug, Metformin Hydrochloride Extended-Release Tablets, extended its recall of its 500mg and 750 mg pills, the U.S. Food and Drug Administration reported this week.
Marksans Pharma Limited of India expanded its earlier initiated recall from June 5 to include an additional 76 unexpired lots of Metformin Hydrochloride Extended-Release Tablets in both 500 mg and 750 mg packages.
The company performed N-Nitrosodimethylamine (NDMA) testing of unexpired identified marketed lots and found that NDMA content in some lots exceeded the acceptable daily intake limit. There have been no reported adverse effects from anyone taking the medication but the company pulled the drugs “out of an abundance of caution,” its statement said.
NDMA could cause cancer based on lab tests and is an environmental contaminant found in water and foods, including meats, dairy products and vegetables.
Metformin Hydrochloride Extended-Release Tablets are supposed to be used in conjunction with diet and exercise to improve blood glucose control in adults with type 2 diabetes.

The tablets are packaged in bottles with the following NDC numbers in different packing configurations.
