| The Wide World of Insulin |
| |
 |
|
Insulin lowers your blood sugar. It helps blood sugar go
into your cells where the sugar is used for energy. Insulin
also helps your body store food. Talk with your doctor or
dietitian if you're worried about gaining weight with insulin.

Different kinds of insulin work at different speeds. Some start
working right away and reach their peak (when they're working the
hardest) quickly. Others take longer to start working and reach
their peak.
You might take two different kinds of insulin. Your body needs a
little insulin working all the time. You also need a bigger amount
of insulin every time you have a meal. For example, many people
take short-acting and intermediate-acting insulins together. Put
a check next to the kinds of insulin you use.

Rapid-acting insulins (lispro and aspart) start working
within 15 minutes. They peak 30 to 90 minutes later. |
| |
|
|
| • |
|
Short-acting insulin (regular) starts working within 30
minutes. It peaks 2 to 4 hours later. |
| |
|
|
| • |
|
Intermediate-acting insulins (NPH and lente) start working
within 2 to 6 hours. They peak 4 to 14 hours later. |
| |
|
|
| • |
|
Long-acting insulins (ultralente and glargine) start working
within 5 to 14 hours. They have little or no peak. |
| |
|
|
| • |
|
Premixed insulins contain mixtures of rapid-acting and intermediate-acting
insulins or short-acting and intermediate-acting insulins.
The start times and peak times depend on the mixture. |
