Identification number:


Mylan Pharmaceuticals ULC is voluntarily recalling four lots of Mylan-Valsartan tablets (40 mg, 80 mg, 160 mg and 320 mg strength) after testing found low levels of an impurity, N-nitrosodiethylamine (NDEA).

Valsartan is a drug used to treat patients with high blood pressure to help prevent heart attacks and stroke. It is also used in patients who have had heart failure or a recent heart attack.

The products are being recalled as a precautionary measure. While the levels of NDEA found in the active pharmaceutical ingredient (valsartan), which is manufactured by Mylan Laboratories Limited in India, are low, they are above what is considered reasonably safe if the drug were taken over a lifetime. Given the length of time that the affected products have been on the Canadian market, this recall is being taken with an abundance of caution.

This latest recall is further to recent recalls and other actions taken in Canada and internationally as a result of NDEA and another impurity, N-nitrosodimethylamine (NDMA), being found in certain drugs (see links below for related communications). Both NDEA and NDMA are classified as probable human carcinogens, which means that long-term exposure could increase the risk of cancer.

Health Canada continues to work with companies and international regulatory partners to determine the scope and root cause of the issue, and to confirm that the necessary actions are taken to address it and prevent it from re-occurring. The Department will monitor these recalls. Should additional safety concerns be identified, Health Canada will take appropriate action and continue to inform Canadians.

Shortages are not anticipated as a result of this recall as there are alternative products available on the Canadian market. As with previous communications regarding NDEA and NDMA, Health Canada is advising that there is no immediate risk to patients taking these medications, since the risk of cancer is with long-term exposure to these impurities. Patients should not stop taking their medication unless on the advice of their healthcare provider.
