Insulin Administration by Syringe



  • Your school nurse or other licensed health care professional must review the procedure with you to ensure that you have the skills to perform insulin administration competently.
  • Because insulin doses depend on blood sugar, food intake and activity levels, it critical to give the exact dose ordered.
  • It is best practice to have a second person double check the insulin dose you draw up before administering it to be sure it is correct; check with your school nurse or the student’s healthcare provider if you are unsure if a double check is needed.
  • Insulin is administered subcutaneously. This is the tissue between the skin and muscle mass, typically known as the fat layer.
  • Insulin is best absorbed when injection sites are rotated. The common injection sites are abdomen, upper arm, upper buttock, and outer thigh.
  • Be sure to check with the student or the student’s parents to discuss preferred injection sites and rotation of sites.
  • Do not shake the insulin vial.
  • The insulin syringe has a needle under the orange cover on the end. The barrel of the syringe has numbers and bars next to numbers to indicate the units of insulin. Underneath the cover on the other end is the plunger which you push to give the insulin.
  • If the student is old enough and has been trained in their diabetic care, encourage them to assist to help the student learn self-care skills, according to the child’s care plan and the school nurse’s direction.
