Abstract
Insulin pens offer the advantages of simplicity, convenience, and more accurate dosing to insulin-using patients with diabetes. The usefulness of insulin pens is not limited to certain subsets of individuals but extends to all patients who might choose this delivery system. By facilitating acceptance and consistent implementation of multiple-dose insulin regimens, pens hold the potential to promote improved blood glucose control and thus reduce the risk of the chronic complications of diabetes. Both clinical experience and the supporting literature suggest that pen delivery systems are an option that should be routinely offered to all insulin users.
