What is the typical onset time for long-acting insulin?

The typical onset time for long-acting insulin is often around 1 hour after administration. Long-acting insulin is designed to provide a steady release of insulin over an extended period, usually lasting up to 24 hours or more. Unlike short-acting insulins, which begin to work quickly, long-acting insulins' onset is more gradual, aligning with the body's natural insulin secretion patterns throughout the day.

This timing allows for better management of blood glucose levels, particularly overnight and between meals, as it helps maintain a basal insulin requirement. Understanding the properties of different insulin types, including their onset, peak, and duration, is crucial for effective diabetes management.
