Owner Compliance
  • Are you rotating injection sites?
  • Are you injecting in the right place? (NOT in the scruff of the neck)
  • Are you storing insulin properly?
  • Are your replacing the insulin timely?
  • Is your injection technique good?
  • Are you compliant with DIET?
  • If all this is ok, change the type of insulin you use.
