HealthDay News — The over-the-counter heartburn drug Zantac (ranitidine) has been recalled in the United States and Canada by French drug maker Sanofi.
The recall comes a month after the US Food and Drug Administration first warned that some versions of the drug contained low levels of the cancer-causing contaminant N-nitrosodimethylamine (NDMA), The New York Times reported. Sanofi is investigating the issue, according to a statement from the company.
Several manufacturers of generic versions of Zantac had already recalled their products, which had been taken off the shelves of major US retailers.
NDMA is found in a variety of products, including cured meats, and is the same contaminant that was found in some versions of the widely used prescription blood-pressure drug valsartan, sold under the brand name Diovan. There have been several recalls of valsartan, The Times reported.
