NEW YORK (1010 WINS) -- Two more drug manufacturers have recalled the widely-used Type 2 diabetes medication metformin, over concerns that it contains too much of the human carcinogen NDMA, a "probable" cancer-causing substance, the FDA announced this week.

The two new recalls follow similar recalls in May from Teva Pharmaceuticals, Marksans Pharma Limited, Apotox Corp. and Amneal Pharmaceuticals.

This week, Lupin Pharmaceuticals Inc. issued the recall for all of its batches of Metformin Hydrochloride Extended-Release Tablets USP, 500 mg and 1000 mg. According to the FDA, "additional analysis revealed that certain tested batches were above the Acceptable Daily Intake Limit for the impurity N-Nitrosodimethylamine (NDMA)."

Another drug maker, Granules Pharmaceuticals, Inc., has recalled 12 lots of its Metformin Hydrochloride Extended-Release Tablets USP, 750 mg, 100 and 500 count.

Metformin is a prescription medication that is used “to improve blood glucose control in adults with Type 2 diabetes mellitus,” the FDA said. Patients who are currently taking the medication should contact their medical providers before they stop, as stopping suddenly could be dangerous to those with serious conditions, the FDA noted.
