What is the shelf life of Lantus after opening?

• A. 14 days
• B. 28 days
• C. 30 days
• D. 42 days

Answer: (B)

The shelf life of Lantus (insulin glargine) after it has been opened is 28 days. Once opened, Lantus should be stored in the refrigerator but can also be kept at room temperature for up to 28 days. This time frame is crucial for ensuring the insulin remains effective for managing blood glucose levels. Beyond this period, the potency of the insulin may diminish, increasing the risk of inadequate blood sugar control. Therefore, understanding and adhering to this 28-day guideline is vital for patients and healthcare providers managing diabetes treatment.
