I know from my fridge breaking down that humira can only handle being at room temp for2 hours before it goes off!!! So you would have to travel with it on ice and keep replacing the ice until you get where you're going. What a hassle!!! If you're already not feeling that the humira is not working as well you will be shocked what happens if you miss it for a week, I had to keep missing doses becuse of infection and I flared terribly after 4 days. My rheumy reckons you should be able to miss a dose if you are completely under control with it, she has upped my mtx dose to give me that window. I'd talk to your rheumy about it, theroretically you should be able to miss a dose as it builds up a half life in your system...I'm probably just confusing you, ring your rheumy, golitho.
