Disposable Insulin Pen have been shown to have several benefits over vial-and-syringe delivery systems, including improved patient acceptability and compliance, better health-related quality of life (possibly related to less painful injections), increased lifestyle flexibility, improved dosing accuracy (reducing the risk of over- or under-dosing and subsequent hypo- or hyperglycemia), and improved ease of use (improving patients' adherence to their insulin regimen). Patients who received the NovoPen (the first insulin pen to be released) in small-scale studies carried out in the late 1980s preferred utilizing this device over alternative strategies, such as the use of vials and syringes and continuous subcutaneous insulin infusion (insulin pumps).
