At what temperature should insulin be stored?

Insulin should be stored in the refrigerator at temperatures between 36 to 46 degrees Fahrenheit. This range ensures the stability and effectiveness of the insulin, preventing it from degrading or losing potency. Insulin is sensitive to temperature extremes, and keeping it within this recommended range is essential for maintaining its efficacy for patients who rely on it for blood glucose management.

Storing insulin at room temperature is acceptable for short-term use, typically for a period of up to 28 days, but it should never exceed temperatures outside the specified refrigeration range for long-term storage, as higher temperatures can lead to deterioration. Therefore, the recommendation of 36 to 46 degrees Fahrenheit provides the ideal environment for insulin to remain effective while also accommodating the needs of patients using it.
