Unopened insulin should be kept in a refrigerator at 2-8°C, in which case the insulin can be stored for a long time.

Opened insulin

Insulin that has been opened and in normal use can be stored at room temperature (18°C to 25°C) without returning to the refrigerator.

Note: Keep it away from light, and avoid placing it near TVs, microwave ovens and other heat-generating household appliances; if the room temperature is too high, put it back in the refrigerator for refrigeration; the insulin should be used up within 4 weeks after opening.
