HUMALOG (Lispro Insulin ) is a mealtime insulin that offers diabetes control and flexibility. The unique rapid-action of HUMALOG (Lispro Insulin ) mimics the body's own insulin activity after meals. HUMALOG (Lispro Insulin ) is absorbed quickly and works within minutes to lower blood sugar. Other mealtime insulins, such as Regular (R), should be injected 30-45 minutes before eating. If Regular (R) insulin is taken at the wrong time, there is a risk of poor blood sugar control and may increase the risk of low blood sugar. Unlike Regular (R) insulin, HUMALOG (Lispro Insulin ) is taken within 15 minutes before or immediately after a meal. The flexible dosing schedule of HUMALOG (Lispro Insulin ) makes it possible to adjust insulin dosages right at mealtime. With the mealtime convenience, HUMALOG (Lispro Insulin ) helps maintain control over blood sugar levels. Good blood sugar control reduces your risk of long-term problems associated with diabetes. HUMALOG (Lispro Insulin ) is a human insulin analog that is rapid acting and helps to lower blood sugar levels.
