How should insulin be stored before and after first use?

• A. Keep in fridge indefinitely.
• B. Store in fridge until first use, then at room temperature for 28 days.
• C. Store at room temperature from the start.
• D. Freeze before use.

Answer: (B)

Maintaining insulin potency and comfort during injections hinges on how it’s stored before and after you first use it. Unopened insulin should be kept in the refrigerator to preserve potency and prevent premature degradation. Once the vial or pen has been started, you can store it at room temperature to reduce injection discomfort. For most insulins, this room-temperature period is up to 28 days; after that, discard the product even if some is left. Do not freeze insulin, and protect it from heat and light. Always check the product label, but the typical guidance aligns with storing in the fridge until first use, then at room temperature for 28 days.
