While all the posts are helpful, you'll likely get a complete, current run down at a major website for diabetes. While it is a complication, traveling with special meds isn't that unusual, and the disease sites I've seen make it their job to get good info and keep it current.

Also, I would check with the drug manufacturer on how long the meds can be at room (plane) temperature. I don't know about your medication, for some, even a short period of time is risky.
