What is the route of administration for lispro insulin?

Lispro insulin, a rapid-acting insulin used to manage blood glucose levels in patients with diabetes, is administered subcutaneously. This route is crucial as it allows the insulin to be absorbed effectively into the bloodstream. Subcutaneous injections provide a consistent and predictable absorption rate, enabling better glycemic control.

Oral administration is not effective for insulin due to its protein structure, which would lead to degradation in the digestive system before it can enter the bloodstream. While intravenous administration can be used in certain hospital settings for rapid onset, it is not the standard route for routine insulin therapy. Intramuscular administration is also not a typical route for insulin, as it can lead to erratic absorption and inconsistent effects on blood glucose levels. Therefore, the subcutaneous route is the preferred and most practical method for administering lispro insulin in daily diabetes management.
