What is NDMA?

NDMA stands for Ni-nitrosodimethylamine.  NDMA is classified as a probable human carcinogen, which is a substance that causes cancer.  It is not only usd to manufacture rocket fuel, but it is also used to induce tumors in animals for laboratory experiments.  The FDA’s daily allowable limit is 96ng.  

On September 13, 2019, FDA issued a statement that some ranitidine products contain NDMA at low levels. On October 2, 2019, the FDA disclosed that they found “unacceptable levels of NDMA” in samples of ranitidine.  This statement prompted voluntary recalls across the world. Additionally, Canada asked companies to stop distributing Zantac and France recalled all ranitidine products.
