If you or a loved one are taking valsartan, you may or may not know about the recent recalls or lawsuits involving it. All of them involve valsartan-products manufactured in China by the pharmaceutical company Zhejiang Huahai Pharmaceutical (ZHP). They all note that ZHP-manufactured valsartan contains N-nitrodimethylamine (NDMA), which groups, such as the World Health Organization (WHO), categorized as a potential carcinogen.
Valsartan Worldwide Recalls
ZHP-manufactured Valsartan could be found in various countries throughout the world. The relatively low manufacturing costs in China made it attractive for countries such as the United States to import it. While these generic drugs may be cheaper to make in China, there are fewer regulations that ensure the safe manufacture of these drugs. This is the tradeoff you get when buying some generic drug imports. Because of the discovery of NDMA in ZHP-manufactured valsartan, the European Union, Taiwan, Canada, the United States, and South Korea announced successive recalls in July 2018.
