Long-Acting Insulin is a type of insulin designed to control blood sugar levels over an extended period, typically lasting up to 24 hours. It is often used by individuals with diabetes to help maintain stable glucose levels throughout the day and night, reducing the risk of high or low blood sugar. This insulin is usually injected once or twice daily, depending on the specific product and individual needs. Unlike rapid-acting insulin, which works quickly to manage blood sugar spikes after meals, long-acting insulin provides a steady release of insulin, helping to keep blood sugar levels consistent over time.
