Health Canada has seized the unauthorized drug, “L-Showm Weight Loss Pills”, being sold at the U-Box store, located at 2809-4500 Kingsway, Burnaby, BC. Health Canada testing found that it contained an undisclosed ingredient, phenolphthalein. Phenolphthalein, which was previously used as a laxative, is no longer authorized for sale in Canada because it may cause cancer. Additional side-effects associated with phenolphthalein include decreased blood pressure, skin rash and gastrointestinal bleeding.
