Like Jim, I keep mine in the fridge until I use it the first time. Then I carry one in my purse and keep another in my medicine drawer. I think it says you can keep it out of fridge as long as it is cooler than 85*, on the instruction sheet included in the box. When I first started on insulin, I was always worried about keeping it cool...it was a pain when we went anyplace. You will get more at ease with things, it just takes time.
