Abstract: The invention relates to a method for minimizing mean blood glucose levels in an insulin dependent patient by administering insulin to the patient in a sufficiently fast manner to provide a difference of 50% or less between high and low blood glucose levels. Advantageously, the insulin is administered to the patient by jet injection and the high and low blood glucose levels differ by an amount that is less than that which would be obtained after injection of insulin by a conventional needle syringe. The invention also relates to a method for reducing mean blood glucose levels in an insulin dependent patient that is receiving insulin through a conventional syringe and needle arrangement. This method provides for administration of the insulin to the patient by jet injection rather than by the syringe by substituting a jet injector for the syringe.
