Refridgerating Insulin Question

When I tap into a bottle, I leave it unrefrigerated. All my other bottles stay in the fridge. This has been the advice of my doctor & educator. If I am running low on an open bottle I may have 2 unrefrigerated bottles on me at a given time. I have never had any problems with the insulin; it is always used with in a month. Oh yeah… I’m using Apidra in my pump.
