Use caution until it’s fixed

New or replacement insulin pumps are not pre-programmed with basal rates or other verified settings (bolus wizard settings, sensor settings, etc.), which must be set up and saved on pumps prior to use. Patients who do not realize this will receive no basal insulin, which can lead to insulin under-delivery. Insulin under-delivery can cause severe hyperglycemia, which may lead to diabetic ketoacidosis. Current device labeling does not clearly identify that these insulin pumps are capable of functioning with the default basal setting of 0.0 units/hr for all 24 hours and that no error message will appear if the default basal setting remains active. Furthermore, the labeling for the affected devices does not highlight that saving the basal settings requires multiple steps and failure to complete all steps will not save the new basal settings, nor that the steps required to set and save a basal profile and other parameters which are used as part of the bolus calculator function are different.
