Unopened insulin

Put the unopened insulin in the refrigerator freezer and use it after it is placed at room temperature. Remember not to put it in the freezer. Put the insulin 1-2cm away from the refrigerator wall to avoid the change of insulin activity due to the low temperature. Try to avoid putting insulin on the refrigerator door, because the refrigerator door is often opened and closed, and severe vibration will reduce the biological activity of insulin.
