What is the typical duration of long-acting insulin in hours?

Long-acting insulin is designed to provide a steady release of insulin into the bloodstream over an extended period to help maintain blood glucose levels. The typical duration of action for long-acting insulin is around 24 hours, making it suitable for once-daily dosing in many cases. This characteristic helps to mimic the natural insulin secretion of the pancreas, allowing for better glycemic control throughout the day and night.

While some formulations can extend a bit beyond 24 hours, the general expectation and clinical use align closely with a 24-hour duration. This is especially important for individuals requiring basal insulin support, as it ensures that they have consistent insulin levels to manage their blood sugar effectively without the peaks and valleys associated with shorter-acting insulins.
