Several drugs used to treat high blood pressure and help prevent heart attacks and strokes have been recalled by Health Canada.
In a release on July 9, Health Canada identified a list of 28 products containing the ingredient valsartan that are being recalled by their manufacturers.
The medications contain the ingredient "valsartan" which was found in some products to have an impurity called N-Nitrosodimethylamine, a potential human carcinogen that could cause cancer with long-term exposure.
The drugs are manufactured by five companies whose valsartan was supplied by China-based Zhejiang Huahai Pharmaceuticals. For example, Swiss company Novartis informed the ministry that their products containing valsartan are not impacted because these products do not contain the ingredient from external suppliers.
There is no acute health threat to patients using the affected medication containing valsartan.
But the agency also says patients taking the drug should check with their pharmacist to learn if their medicine is being recalled.
Health Canada is advising Canadians taking any valsartan drug to contact their pharmacist and health-care provider to determine what steps to take.
