title: Analysis of insulin pen devices for the treatment of diabetes mellitus.
abstract: Insulin pen devices allow for accurate, flexible, and less complicated delivery of insulin for the treatment of diabetes mellitus. These devices permit small dose administration, and can be used by patients with limited dexterity and visual impairment. These characteristics may prove beneficial when considering their usefulness. The article by Hanel et al. in this issue of Journal of Diabetes Science and Technology clearly points out that the OptiClik reusable pen may underdose insulin early after cartridge replacement unless properly primed. Insulin pens clearly offer several advantages over traditional vials and syringes. However, patients must be well educated in their use, with continued communication between them and their health care provider to enable good glycemic control.
