Canada. Health Canada is warning consumers that ‘Liqiang 4 dietary supplement capsules’ contain glyburide, a prescription drug used to treat type 2 diabetes. The supplement could thus have life-threatening consequences in diabetics and in individuals with low blood sugar if used without medical supervision. Liqiang 4 capsules, promoted for use in the control of diabetes, are not approved for sale in Canada. However, consumers could probably buy them through mail-order or over the Internet. Consumers are advised to immediately stop using these products and to seek medical attention, especially if they are currently being treated with anti-diabetic drugs.
