Sanofi pulls Zantac from U.S. and Canada after carcinogen found
Sanofi SA said on Friday it would recall popular heartburn medicine Zantac in the United States and Canada, after the medicines were linked with a probable cancer-causing impurity. The French drugmaker said it was working with health authorities to determine the level and extent of the recall, which it called a precautionary measure being taken due to possible contamination with a substance called N-nitrosodimethylamine (NDMA).
