A: If your room temperature goes above about 80 degrees Fahrenheit, you would be safer to keep your insulin in the refrigerator. Q: I use an insulin pen. I have heard I should keep my pen at room temperature for only two weeks. But insulin in vials can be kept at room temperature up to 28 days.
Takeaways: Shuttling opened insulin vials between refrigeration and room temperature does not appear to affect the insulin's potency under these conditions and time periods. However, manufacturers of insulin pens do not recommend storage in a refrigerator once a pen is opened and in use.pened vials of insulin detemir (Levemir) are stable for up to 42 days at the recommended conditions. Insulin should not be allowed to freeze; if vials or pens are found to be frozen, they should be discarded and replaced with fresh supplies.
