Health Canada is warning consumers not to use unauthorized Festal Plus tablets seized from GD Health Town, in Coquitlam (329 North Road #215), B.C., because the product is labelled to contain a prescription drug (ursodiol) and may pose serious health risks. The unauthorized product is promoted for use in adults and children eight years of age and older who have gastrointestinal problems to help digest food; however, ursodiol is a prescription drug in Canada and is only authorized for the treatment of certain liver diseases. Selling unauthorized health products in Canada is illegal. Unauthorized health products have not been approved by Health Canada, which means that they have not been assessed for safety, efficacy and quality and may pose a range of serious health risks. For example, they could contain high-risk ingredients, such as prescription drugs, additives or contaminants that may or may not be listed on the label. These ingredients could interact with other medications and foods. In addition, these products may not actually contain the active ingredients that consumers would expect them to contain to help maintain and improve their health. The product is also not labelled in both English and French as required in Canada. Prescription drugs should only be used under the advice and supervision of a health care professional because they are used to treat specific conditions and may cause serious side effects. Prescription drugs can only be legally sold to consumers in Canada with a prescription.
