How should insulin be stored and for how long can opened vials remain at room temperature?

• A. Refrigerate unopened vials; opened vials can be kept at room temperature for about 28 days, but verify product-specific guidance; protect from heat.
• B. Store both opened and unopened at room temperature indefinitely.
• C. Refrigerate unopened vials; once opened, room temperature for about 28 days.
• D. Keep all insulins at room temperature forever.

Answer: (A)

Insulin stability depends on storage conditions. Unopened vials should be kept in the refrigerator to preserve potency until you’re ready to use them, protecting them from heat and light. Once a vial is opened, it can be stored at room temperature for about 28 days to make injections more comfortable and convenient, but you must keep it away from heat and direct sunlight and avoid exposing it to temperatures outside the recommended range. Always check the product’s labeling for the exact window, as some formulations have different guidance. The idea is that potency declines with time at room temperature, so indefinite storage there isn’t correct.
