Although not all people with diabetes need insulin treatment, insulin is indeed a life-saving medicine for diabetic patients. Without insulin, the life span of diabetic patients will be affected.
However, insulin is particularly delicate and improper storage will affect its effectiveness. If the following three situations occur, insulin should no longer be used, and it will not lower blood sugar even if it is used.
3 Insulin can no longer be used
1. The expiry date has expired.
2. Color changes: Once the color becomes darker or even brown, it means that the insulin has completely failed.
3. There is a precipitate that does not disappear after shaking: If there is a precipitate on the insulin and it appears turbid and does not disappear after shaking, then the insulin has expired and can no longer be used. If a small amount of precipitates and disappears after gentle shaking, the insulin is effective.
Five details you must pay attention to when storing insulin
1. Unused insulin: Store in the refrigerator freezer at 2 to 8°C. Do not place it on the refrigerator door or near the refrigerator wall.
2. Insulin in use: Bottled insulin can be placed back into the cold storage compartment of the refrigerator after use.
The insulin pen in use cannot be put back into the refrigerator after use, and the needle must be removed after use. To prevent air from entering the pen and affecting the accuracy of dose injection.
3. Do not check luggage when taking a plane: Because the temperature in the luggage compartment at high altitude is also tens of degrees below zero, insulin will be frozen.
4. When going out: Put insulin in a thermos cup or bag or a special insulation bag for insulin to prevent overcooling or overheating. It can also be stored in a close-fitting pocket for a short period of time.
5. Avoid high temperatures: Because insulin works at body temperature, do not leave insulin on the hot beach ground for a long time, and do not let it be exposed to direct sunlight for a long time to avoid insulin failure due to high temperature.
Many people with diabetes worry that occasionally high room temperature will affect the effect of insulin, but in fact it will not.
