Does insulin need refrigeration?

Insulin needs to be refrigerated. If insulin is not opened, it is recommended to put it in the refrigerator, the temperature is set at 2-8℃, so that the time of preservation can refer to the production date of the drug label. Put it in the refrigerator, try to stay away from the refrigeration components, because the temperature inside the refrigerator is not uniform. Insulin is a protein hormone composed of amino acids. If the temperature is too low or too high, it will cause protein denaturation and affect the efficacy of insulin. If the insulin has been opened and is being used, it can not be placed in the refrigerator, but the temperature is required to be below 25 ° C. The use time should not exceed one month. If it exceeds one month, it should be discarded even if it is not used up.
