How should insulin be stored before administration?

Insulin should be stored in the refrigerator and warmed before use to maintain its effectiveness and stability. Insulin is a delicate medication that can degrade if exposed to extreme temperatures. Storing it in the refrigerator helps preserve its potency, as it is ideally kept between 36°F to 46°F (2°C to 8°C).

Before administration, it's recommended to allow the insulin to reach room temperature, as this may help reduce discomfort when injecting. Cold insulin can cause pain or discomfort upon injection, so letting it warm slightly is beneficial while being cautious not to leave it at room temperature for extended periods to avoid degradation.

Storing insulin in a warm place or at room temperature at all times can lead to decreased effectiveness, while keeping it protected from direct sunlight is appropriate; however, refrigeration is crucial for long-term storage. Storing it in direct sunlight can also harm the medication, but it's secondary to the need for refrigeration prior to use.
