STAT Plus: FDA asks manufacturers to recall heartburn drugs over traces of a possible carcinogen
After months of deliberation, the Food and Drug Administration has asked all manufacturers of a particular heartburn medicine known as ranitidine, sold under several brands including Zantac, to withdraw their drugs because “unacceptable levels” of a possible carcinogen may develop in the pills over time.
Specifically, the agency determined that levels of NDMA, an organic chemical that was once used to make rocket fuel and is an unintended byproduct of certain chemical reactions, may gradually increase and can increase significantly when stored in higher heat than room temperature.
