What is the duration of Lantus/Glargine insulin?

Lantus (insulin glargine) is a long-acting insulin that provides a steady level of insulin in the bloodstream over an extended period. The duration of Lantus typically ranges from 24 to 36 hours. However, the most clinically significant duration recognized is approximately 24 hours, making it effective for once-daily dosing, which is ideal for managing blood glucose levels throughout a 24-hour period.

This property allows for the maintenance of basal insulin levels without significant peaks, which helps in minimizing the risk of hypoglycemia while controlling blood glucose levels. Lantus is often chosen for patients who require long-term insulin therapy, and its predictable release makes it suitable for establishing a stable insulin regimen.

While other insulins may have shorter durations, or longer durations, Lantus’ recognized effective duration predominantly falls within the 24-hour range, making it a reliable option for continuous management of diabetes.
