From America OnLine:

My son, age 8, recently began using Humalog along with Humulin Ultralente. I know that Humalog is fast acting, but can you tell me how long it stays in the system and when it peaks?


The way to tell how long the Humalog is lasting is easy: check the blood sugar after eating (probably about 2-3 hours after a meal).

See our page about insulin lispro.
