General questions
WHY CAN'T I LEAVE THE PEN NEEDLE ON THE PEN FOR FUTURE USE?
When you go from a warm to cold place, the insulin shrinks and air enters the insulin cartridge through the needle. When extra air is in the insulin cartridge, your dose won't be right. When you go from a cold to warm place the insulin swells and leaks out through the needle. If you use NPH or 70/30, fluid may leak out while particles stay in. This will change the strength of your insulin.
