i haven't had too much luck with transporting enbrel. the soft pack coolers definately dont work for more that 2 or 3 hours. if you are traveling by car you can stop and get ice so its no problem, but on the plane it always seems to get warm. even if you make it to your destination, then you travel to the hotel and no refer! (if you stay in the cheap hotels like i do). and the ice bucket really doesnt work! melts sometime in the middle of the night...then you are dosing some warm hamster cells that do you no good.
if you are only traveling for a week you can double dose before you go and when you get back...you have to ask your doc about this - to see if it is ok for you.
