Dozens of "sexual enhancement" products and workout supplements sold in B.C. shops were seized and recently added to Health Canada's list of unauthorized products. In recent months, thousands of unauthorized items were taken off shelves of Lower Mainland stores with the public being warned the products could pose "serious health risks." The latest product seizures happened at retail stores and warehouses in Vancouver, Delta, Maple Ridge, Surrey, Abbotsford, New Westminster and Coquitlam. Many of the products were found to have tadalafil when tested. According to Health Canada, tadalafil is a prescription drug used to treat erectile dysfunction. It should only be used under a doctor's supervision, because it can cause life-threateningly low blood pressure when combined with certain medications, and comes with a risk of heart attack and other cardiovascular side effects in people with heart problems, Health Canada said. One ingredient found in many of the workout supplements was yohimbine, which is also a prescription drug. The federal health agency said using yohimbine can lead to "serious adverse reactions," especially for those with high blood pressure, or heart, kidney or liver disease. The products added to Health Canada's are just the latest to join dozens of other previously identified unauthorized workout supplements and sexual enhancement products, including "Lucky Lady" and "ResERECTION." Anyone who's been using any of the products listed below is told to stop taking it immediately, and to contact their doctor if they have health concerns. They're also asked to report the products to Health Canada. According to Health Canada's list, which was updated on May 5, these products were seized from various retail locations across the Lower Mainland: With files from CTV News Vancouver's Kendra Mangione and Meagan Gill
