That burning feeling in your chest after you eat a heavy meal could be heartburn. Or it could be worry over the drugs you’ve taken to treat that heartburn. Among the top medical stories of 2019 was the discovery of contaminants in common medicines, and ranitidine—best known as Zantac—took up a large share of those headlines. A cancer-causing substance known as NDMA has been repeatedly found in one of the most popular antacid drugs in the United States.

The scary news continues in 2020. On Wednesday, the Food and Drug Administration announced voluntary recalls of prescription forms of ranitidine by two generic drug companies, Appco Pharma and Northwind Pharmaceuticals, bringing the total number of ranitidine recalls to 14 in the past five months. The agency also reported that Mylan Pharmaceuticals recalled three lots of Nizatidine (Axid), a similar drug, again because of NDMA.
