Amneal yanks ulcer drug off U.S. shelves on fears of carcinogen contamination

After a carcinogen scare late last year, the FDA recently opted to yank the heartburn drug Zantac and its generics off U.S. shelves. Now, Amneal Pharmaceutical will pull several lots of one of its heartburn meds off the market on fears the same probable carcinogen may have tainted its supply.

Amneal has voluntarily recalled three lots of Nizatidine Oral Solution on fears they contain levels of N-Nitrosodimethylamine (NDMA), a probable human carcinogen, above the FDA's accepted limit.
