Plan ahead. Make sure you: • Get all your immunizations. Find out what’s required for where you’re going, and make sure you get the right shots, on time. • Control your ABCs: A1C, Blood pressure, and Cholesterol. See your health care provider for a check-up four to six weeks before your trip to make sure your ABCs are under control and in a healthy range before you leave. • Ask your health care provider for a prescription and a letter explaining your diabetes medications, supplies, and any allergies. Carry this with you at all times on your trip.
