Contact your doctor or pharmacist for a letter detailing your medical condition or for a list of your prescriptions. Carry those prescriptions in their original, labeled containers. Over-the-counter drugs are allowed, but keep them in the original packaging.
Carry juice, drinks or water only if your medical condition requires that you have nourishment or liquids on hand--again, a letter from a physician can detail your needs. Gels or freezer packs designed to keep liquids or medications cold are allowed, but must be commercially labeled and not homemade.
Baby formula and food, plus breast milk, may be carried through the security checkpoint and on board in "reasonable amounts"--what is reasonable is determined by the security personnel. If you do not want them to be X-rayed, request a hand search of the items.
Wheelchairs, cosmetic prostheses and underwear with breast enhancements for women who have undergone a mastectomy are allowed. It is best to declare the items that are not readily noticeable to the agent as you approach the check area.
Carry your diabetes supplies in one small bag that can be easily displayed to an agent. Syringes, test strips, lancets, alcohol swabs and insulin (up to 8 oz.) can be carried on board, but must be declared at the security checkpoint. Glucose tablets or a glucose sugar tube are allowed.
Pack your vital medical supplies, if possible, in 1 qt. clear zip bags that can be seen as your bags pass through X-ray machines. If your medical supplies or necessary liquids cannot fit in one of the small bags and any liquid item exceeds 3 oz., you must declare them for a hand search.
