Sun Pharmaceuticals Industries Inc., (Sun Pharma) is recalling one lot of Riomet ER, an extended-release version of the type 2 diabetes drug metformin because it contains unsafe levels of a probable cancer-causing impurity known as NDMA, short for N-nitrosodimethylamine, the Food and Drug Administration (FDA) announced.

Riomet ER is one of several extended-release formulations of metformin that have been recalled over health concerns due to elevated levels of NDMA. The impurity is an environmental contaminant that is found in some food and drinking water. The FDA has established that consuming up to 96 nanograms of NDMA daily is reasonably safe based on lifetime exposure. But, “sustained higher levels of exposure may increase the risk of cancer in humans.”

NDMA has been detected in the high blood pressure and heart failure drug Valisure and similar products in the ARB family of drugs. More recently, unsafe levels of NDMA have been found in the heartburn drug Zantac and other medications containing ranitidine. In April, the FDA removed Zantac from the U.S. market due to safety concerns.
