Types of Insulin

A newly diagnosed patient learned that insulin is available in many different types, and each type works differently in the body.

Short-Acting Insulin

Begins to work 30 minutes after injection, peaks in two to three hours and lasts for three to six hours.

Intermediate-Acting Insulin

Begins to work later than a short-acting insulin but works for a longer time.

Long-Acting Insulin

Begins working in one to two hours, continuously works in the body and lasts for approximately 24 hours.

Rapid-Acting Insulin

Begins to work in approximately 15 minutes after injection, works the hardest in about one to two hours and lasts for three to four hours.

Premixed Insulin

Premixed insulin is available to make it easier for people to inject two different types of insulin without having to mix it themselves.

All insulin is measured in units and drawn up into a syringe for injection on the abdomen, thighs, or upper arms.

Some people take multiple daily injections of insulin using a fine needle syringe. Other insulin delivery devices include insulin pens or insulin pumps.

Syringes are single use and come in different gauges for comfort and different dosing sizes.

Pumps are about the size of a pager and are programed to deliver small amounts of insulin throughout the day.

Insulin pens are prefilled insulin syringes that the user can dial up the correct units of insulin and reuse.
