What is the onset of action for lispro insulin?

Lispro insulin is classified as a rapid-acting insulin. It is designed to mimic the natural insulin response that occurs after meals, allowing for quick glucose regulation. The onset of action for lispro insulin is approximately 15 minutes after injection. This rapid onset is beneficial for individuals with diabetes, as it allows them to administer the insulin close to meal times, helping to manage blood sugar spikes that can occur after eating. Following administration, peak activity typically occurs within 1 to 2 hours, and the total duration of action can last about 3 to 5 hours. This pharmacokinetic profile makes lispro an effective choice in diabetes management, particularly for mealtime glucose control.
