Insulin

Knowing an insulin's type will tell you how fast it starts to work and how long it works. This is called action or activity. The chart below shows the time activity of some of the short acting, intermediate acting and long acting human insulins.

  • Onset - shows how long it usually takes for the insulin to start working.
  • Peak - The peak is when the insulin usually has its strongest effect.
  • Duration - The duration of activity is how long insulin continues to work.
