This results in under-utilization of glucagon kits to treat or prevent severe hypoglycemia1-4 • Furthermore, glucagon injection kits require user training and multiple preparation steps. These are barriers to their prescription and effective utilization, especially under emergent circumstances1,2 1. Harris G. Pract Diabetes Int. 2001;18(1):22-25 2. Kedia N.
