More and more people with diabetes are now using insulin therapy, and manufacturers have invented a variety of different insulin syringes to make it easier for patients to use. However, those patients who need insulin injections frequently should be aware that insulin is “delicate” and needs to be stored carefully. Improper storage can damage the hypoglycemic effect of insulin and adversely affect the patient’s blood sugar control. What are the dos and don’ts of insulin storage? You should: 1. Insulin used normally can be kept at room temperature (not more than 30℃). 2.Insulin used unopened is stored in a refrigerator freezer at 2 to 8℃. 3.Store spare insulin in an insulated bag to carry with you when you travel. You should not: 1. Freeze insulin. 2.Expose insulin to direct sunlight, such as a windowsill. 3.Put insulin in a hot place, such as on a radiator. 4.Use insulin that has hard lumps or discoloration. 5.Use insulin that has passed its shelf life.
