For better
injection comfort and
insulin efficiency, it is advisable to take the insulin out of the refrigerator a minimum of one hour prior to injection: cold insulin increases the pain of the injection and slows down the insulin absorption.
Any insulin vials or cartridges which are not open should be stored in the refrigerator between 2o and 8oC. Any open insulin vial or cartridge can be safely stored at room temperature for up to one month (please refer to insulin manufacturer's recommendations).
Never use insulin after the expiry date and avoid exposure to extreme temperatures.
