The range of 37-40 degrees C is about 100 degrees to 105 F. Not many drugs are meant to be stable at these temperatures. The fridge is far better in every way for Creon, in fact all your drugs are typically kept below 16C or 60 degrees F. Lower temps around 2-4 degrees C. (34-38F.) which should be about mid-fridge, is ideal. Just don't freeze them. Like all medications kept in the fridge, the lid should be gas tight so you don't smell up your food or moisten your meds. Most prescription bottles in the U.S. are not gas tight. I use lab containers but a canning jar or Mason Jar can hold several bottles.
Sorry I didn't check this post earler,
