Reason for Recall: The affected cartridges may be at risk for leaking. A cartridge leak could potentially result in the delivery of too much or too little insulin, which could lead to unexpected high or low blood glucose levels. Too much insulin can result in severe low blood sugar (hypoglycemia) and too little insulin can lead to severe high blood sugar (hyperglycemia), both of which can lead to serious injury or death.
