What is the peak time for long-acting insulin?

The peak time for long-acting insulin is typically around 5 hours after administration. Long-acting insulin is designed to provide a steady and prolonged level of insulin in the bloodstream, mimicking the body's natural insulin production. This type of insulin does not have a sharp peak like rapid-acting or short-acting insulins. The 5-hour timeframe represents the period when the insulin is most effective in lowering blood glucose levels, although its action can last anywhere from 12 to 24 hours or more, depending on the specific formulation.

With long-acting insulins, the onset and duration are essential to understand, as it allows for better management of blood glucose levels throughout the day and night, ensuring that individuals with diabetes maintain stable glucose levels.
