  2. Be familiar with your AAI, order a free trainer pen. (Links below)
  3. Teach your child how to use pen, practice how to use it, by using a trainer device every three to four months.
  4. Teach the people around you how to use an AAI.
  5. Have an action plan with your AAI.
  6. Wear Medical ID.

  10. Sign up with the manufacturer, to get expiry date alerts. (links below)
  11. Always have 2 AAI, with you in case first one does not work, or Biphasic anaphylaxis occurs. (A second reaction 1 hour to 72 hours after the first attack.)
  12. Schools can order AAI themselves for school time, but check with school what is the expiry date, in case gets overlooked.
  13. As your child grows, they will need a different dosage of AAI. Check with your consultant/doctor when this is needed.
  14. Have your doctor put your adrenaline auto-injector on repeat prescription, so it does not have to reviewed by a doctor every time you order one.
  15. Disposal of used or expired AAI, return to any pharmacy.
