Once dispensed, insulin can be stored at a controlled room temperature for how long?

1. Up to 6 months

2. Up to 28 days

3. Until the expiration date listed on the vial

4. Up to 14 days

The correct answer is: Up to 28 days

Insulin, once dispensed, can be stored at a controlled room temperature for up to 28 days. This is important for ensuring the stability and effectiveness of the insulin. Storing it at room temperature is beneficial as it avoids the discomfort of injecting cold insulin and minimizes the risk of it becoming less effective. While insulin has a shelf life that may extend longer when stored properly (like refrigerated), after it has been opened and exposed to room temperature, it should only be used for up to 28 days. This is due to the fact that after this period, the insulin may lose potency, which can affect diabetes management. The other choices do not align with standard guidelines for insulin storage after being dispensed. For example, a storage duration of 6 months and 14 days is longer than recommended, while relying on the expiration date listed on the vial without considering exposure to room temperature does not account for the potential reduction in medication effectiveness after it has been opened.
