Rapid-Acting Insulin

Action of Rapid-Acting Insulin

Rapid-acting insulin begins working very quickly inside the body - usually within 5 and 10 minutes. This type of insulin should be taken just before or just after eating. It operates at maximum strength for one to two hours and duration is typically up to four hours. Because the activity of rapid-acting insulin starts and finishes so fast, it does not lead to hypoglycemia as often as the older insulins. Extra fast-acting insulins are very convenient because they allow diabetic patients to inject themselves just when they eat.

Rapid-Acting and Long-Acting Insulin

Some diabetes patients use rapid-acting insulin at mealtimes, and also long-acting insulin for 'background' continuous insulin.

Commercial Rapid-Acting Insulin

At present there are two types of rapid-acting commercial insulin available: LISPO insulin (Lysine-Proline insulin) and ASPART insulin. Both LISPRO and ASPART insulins are only available by prescription.

Warning: Always consult your doctor or diabetes counselor about which type of insulin is best for your diabetes.
