When I was on Humira and was traveling, I just adjusted my injection days so that I had an injection just before leaving, then had an injection just after returning. I was on weekly injections, so it was a bit of a hassle. If I knew there would be a fridge where I was staying, I'd bring a syringe with me. I got a travel cold pack from the manufacturer for free, and it was great. Even though you can leave it out at room temp for quite a while, I'd be concerned about uneven ambient temperatures, so a cooler is a good idea.

Now I'm on Simponi, which is monthly, so I have a lot more flexibility.
