Every year, millions of people used the drug ranitidine to treat heartburn. The branded name is Zantac. Despite this widespread use, officials recently determined that it poses a cancer risk, and it has been recalled.
The issue is that the U.S. Food and Drug Administration (FDA) has acceptable levels set for N-Nitrosodimethylamine (NDMA). The amount that was found in Zantac exceeded those levels. This is an issue since NDMA has officially been classified as a probable human carcinogen.
