A sixth company has recalled its version of Type 2 diabetes drug Metformin Hydrochloride Extended Release Tablets 750 mg after finding some of the medicine contained too much of carcinogen NDMA.

Granules Pharmaceuticals’ company-written, FDA-posted recall notice says one lot tested as having N-Nitrosodimethylamine content that exceeded the FDA’s daily consumption limits. So the company took the precautionary step of recalling 12 lots of metformin.

One of the retail pharmacies selling this version of metformin is Walmart, at “select Walmart stores.” The bix box giant announced the recall on its website after the FDA posting and linked to that alert. Walmart customers should follow the recommendations below for all those affected by this recall.

In June, Apotex, Amneal, Teva and Marksans Pharma and Lupin recalled their metformin extended release tablets for the same reason after the FDA said it requested five companies do so. The FDA devoted a website page to information for metformin patients, but it hadn’t been updated with this recall as of Tuesday morning.

With these recalls and past recalls of blood pressure and heart medication for carcinogens such as NDMA and its cousins, the recommendation has been keep taking the medication until deciding on another treatment course with a doctor or pharmacist.

Granules pulled 11 lots of 100-count bottles, Nos. 4920003A, expiration date May-21; 4920004A and 4920005A, expiration date Jun-21; 4920009A, expiration date Nov-21; 4920010A, expiration date, May-22; 4920011A and 224920012A, expiration date Jun-22; 4920013A and 4920014A, expiration date Jul-22; 4920015A, expiration date Aug-22; and 4920016A, expiration date Jan-23.
