Any ideas on how to travel with medicine that need to be refrigerated?

Travel: Can give to flight attendant for safe keeping in refrigerator if flying, or place in sealed bottle in cooler if by car.

Keep med cold: A cooler with ice is very helpful in between destinations. Hotels, airlines, and cruise ships are very helpful if you inform them. In a tight spot, one might hang a container out the window on a cold night or submerge a sealed container in a cold stream. In a remote location, a foldable solar panel can power a small refrigerated cooler.
