What is the peak time for Humalog insulin?

The correct peak time for Humalog insulin is approximately 30 minutes after administration. Humalog, which is a rapid-acting insulin, typically begins to lower blood glucose levels within 15 minutes, peaks at around 30 to 90 minutes, and has a duration of action of around 3 to 5 hours. Therefore, understanding that it reaches its peak effect around the 30-minute mark is essential for effective patient management, particularly in coordinating meals with insulin administration to achieve optimal glucose control. This timing helps inform nursing care decisions, especially regarding monitoring blood glucose levels and preventing hypoglycemia.
