Insert C: Types of Insulin

The onset is how soon the insulin starts to lower your blood glucose after you take it.

The peak is the time the insulin is working the hardest to lower your blood glucose.

The duration is how long the insulin lasts-the length of time it keeps lowering your blood glucose.

The times shown in the chart are estimates. Your onset, peak, and duration times may be different. You'll work with your health care team to come up with an insulin plan that works best for you.
