U-500 Insulin

The VA standardizes the prescribing and dispensing of U-500 insulin at VA facilities according to ISMP guidelines. The educational material we present here can be used to educate VA patients as to how U-500 insulin and associated needles will be dispensed to them. Caregivers are encouraged to have diabetic patients review these and familiarize themselves with the procedures.
