The discontinuation of all U-40 insulins as well as all protamine zinc insulins will require you, as a diabetes educator, to educate patients about their insulin needs and the proper use of alternative insulins and insulin syringes. Table 2 is a summary of all of the insulins presently available in the United States as of December 1991. Now that the insulin diabetes product list has been shortened, we can hope that this will decrease some of the confusion in terms of insulin products available. Note, however, that in the future we may have additional insulins available in terms of different mixtures of regular and NPH. We also hope to have available within the relatively near future insulin analogs that have different amino acid sequences that cause insulins to have a much more rapid pharmacologic effect than is presently possible. Note also that regardless of the type of insulin used, the objective of insulin therapy in patients with diabetes is to bring blood glucose levels as close to normal as possible, while at the same time allowing the patient to live as flexible and normal a life-style as possible.
