Zantac Heartburn Drug May Contain Carcinogen: FDA
Posted on September 14, 2019

A substance that could cause cancer has been found in some ranitidine heartburn and ulcer medicines, including the brand-name drug Zantac, and the source of this contamination is being investigated, the U.S. Food and Drug Administration says.
While preliminary tests found low levels of the nitrosamine impurity N-nitrosodimethylamine (NDMA) in some ranitidine products, the FDA said this does not mean patients taking the drugs should stop using them now.
