More companies recall a Type 2 diabetes drug. It could contain too much of a carcinogen

Three makers of Type 2 diabetes drug Metformin announced recalls Friday, the U.S. Food & Drug Administration reported.

The reason for the voluntary recalls: the U.S. Food & Drug Administration determined that these medications might have too much NDMA, a substance that can cause cancer in certain amounts.

The three drug manufacturers

Apotex, which is is produced by a company headquartered in Weston in Broward County, is expanding its recently announced retail level recall of its Type 2 diabetes drug Metformin Hydrochloride Extended-Release Tablets, USP 500mg, to consumer level.

In addition to Apotex, Teva Pharmaceuticals USA, Inc. recalled 14 lots of Metformin Hydrochloride Extended-Release Tablets, USP 500 mg and 750 mg, 100 and 1,000 count bottles, in the United States. Teva has joint headquarters in New Jersey and Israel.

And Marksans Pharma Limited, headquartered in India, recalled its Metformin Hydrochloride Extended-Release Tablets, USP 500mg, lot # XP9004. These pills, with an expiration date of December 2020, were distributed by Time-Cap Labs from Farmingdale, New York, nationwide to wholesalers that distribute to pharmacies.

Patients who take these medication should contact their pharmacy to return the pills, the FDA says. They are also advised to consult their doctor for medical advice on how to continue their therapy to control blood sugar levels.

According to the FDA, Apotex Corp agreed to recall its lot, “and out of an abundance of caution, the company is extending the recall to all lots of Metformin Hydrochloride Extended-Release Tablets in the U.S. “

Apotex stopped selling Metformin Hydrochloride Extended-Release Tablets, USP 500mg, domestically in February and there should only be limited product on the market. Apotex has not received any reports of adverse events related to the drug’s use so far, the FDA said.
