Hi K., I am an insulin dependent diabetic and I wear an insulin pump, and I am also a diabetes nurse educator. I have traveled internationally and really what you should have is a letter from your doctor saying you are diabetic and are required to carry needles, insulin, lancets for your meter etc. When you go through security, you will be required to put any liquids you are taking on board as carry on items in a quart sized clear plastic bag. This includes things like insulin and purell. The insulin should have the label from the pharmacy if possible on it or a copy of it with it. I have to say though with all the preparation I have done to travel and the many times I have traveled, not once has anyone questioned these items or asked to look at my prescription labels. Do not check any of your diabetes supplies, you never know when they will loose your luggage or what temperature they will be at before you get them back. Always be prepared with dry goods like snacks, some form of glucose like candy or glucose tablets to treat low blood sugars. You never know when there will be a delay to getting food. Glad to see you are getting prepared, have a great trip! C.
