The U.S. Food and Drug Administration and other healthcare regulators are investigating whether diabetes drug metformin had contaminations of a cancer-causing chemical that prompted a recall of a commonly used heartburn medication this year.
The move is part of the FDA’s broader push to investigate a range of drugs for the presence of the carcinogen, known as N-nitrosodimethylamine (NDMA), with heartburn drug Zantac being recalled this year for fear it contained NDMA.
