WINNIPEG Health Canada has issued a recall covering three types of blood pressure drugs from the class of medication known as sartans.’ A news release from Health Canada lists the three drugs recalled, which are produced by several manufacturers, as irbesartan, losartan and valsartan. Sartans are prescribed to treat patients with high blood pressure to help prevent heart attacks and stroke. They are also used in patients with heart failure or those who have had a recent heart attack. Health Canada says people who have been prescribed these medications should still keep taking them, unless a doctor or a health-care provider has advised you to stop.
