How long does long acting insulin last?

Long-acting insulin is designed to provide a steady release of insulin over an extended period to help control blood glucose levels throughout the day and night. The duration of action for long-acting insulin typically lasts around 24 hours, making it suitable for once-daily dosing in many patients. This duration allows for consistent insulin coverage, which is particularly beneficial for individuals with diabetes who need stable blood glucose control.

While some formulations may vary slightly, 24 hours is the standard duration most often associated with long-acting insulin, thus making this the correct choice. Longer insulin coverage minimizes fluctuations in blood sugar levels, reducing the risk of both hyperglycemia and hypoglycemia, which can be critical in diabetes management.
