Advisory - Several drugs containing valsartan being recalled due to contamination with a potential carcinogen

OTTAWA, July 9, 2018 /CNW/ -

Issue: Several drugs containing the ingredient valsartan are being recalled by their manufacturers. An impurity, N-nitrosodimethylamine (NDMA), was found in the valsartan used in these products. The valsartan was supplied by Zhejiang Huahai Pharmaceuticals. NDMA is a potential human carcinogen, which means that it could cause cancer with long-term exposure. Five companies have affected products, which are being recalled (identified in table below).

Drugs containing valsartan are used to treat patients with high blood pressure to help prevent heart attacks and stroke. These drugs are also used in patients who have had heart failure or a recent heart attack.
