New FAA flying guidelines for people with diabetes. (For full guideline see this web page)

Because of forgery concerns, prescriptions and letters of medical necessity will not be accepted from doctors or pharmacists.

Notify the passenger screener that you are carrying supplies for your diabetes care. If you are wearing an insulin pump, ask that they visually check it. Advise the screener if you are having a low blood sugar problem that needs medical assistance.

Passengers may board with syringes or insulin delivery systems only if they can produce a vial of insulin with a professional, pharmaceutical pre-printed label which clearly identifies the medication. No exceptions will be made. Since the prescription label is on the outside of the box containing the vial of insulin, the FAA recommends that passengers refrain from discarding their insulin box and come prepared with their vial of insulin in its original pharmaceutically labeled box. We advise those using Glucagon to keep their glucagon kit intact in its original pre-printed pharmaceutically labeled container.

For passengers who have diabetes and must test their blood glucose levels but who do not require insulin, boarding with their lancets is acceptable as long as the lancets are capped, and as long as the lancets are brought on with the glucose meter that has the manufacturer's name embossed on the meter.
