A school may maintain a supply of glucagon in any secure location that is immediately accessible to a school nurse or a delegated care aide. A physician, a physician assistant who has prescriptive authority under Section 7.5 of the Physician Assistant Practice Act of 1987, or an advanced practice registered nurse who has prescriptive authority under Section 65-40 of the Nurse Practice Act may prescribe undesignated glucagon in the name of the school to be maintained for use when necessary. Any supply of undesignated glucagon must be maintained in accordance with the manufacturer's instructions. A school nurse or delegated care aide may administer undesignated glucagon if he or she is authorized to administer the undesignated glucagon through a student's diabetes care plan and if the student's prescribed glucagon is not available on-site or has expired. Immediately after the administration of undesignated glucagon, a school must notify the school nurse, unless the school nurse was the one administering the undesignated glucagon, and the student's parent or guardian or emergency contact, if known, and health care provider of its use.
