Insulin Pens: the Modern Delivery Devices

Strict glycemic control helps in reducing complications and mortality in patients with diabetes. Insulin remains the mainstay in treatment of diabetes. One of the most important barriers to insulin therapy is the use of conventional insulin delivery system, which remains time-consuming, cumbersome, inconvenient and painful. Insulin dosing via syringe is associated with a high risk of dosage errors. The modern pen devices have various advantages over the conventional insulin delivery methods. The user-friendliness and comfort of injection makes the initiation of insulin easier. The ease of use of insulin pens and the flexibility of incorporating insulin injections into a busy lifestyle may improve diabetes control with much less effort, while maintaining the quality of life for the diabetic patients.
