|Types of insulin|
When you have type 2 diabetes, your pancreas still produces insulin. Over time, however, less and less of this hormone may be produced. This leads to the need to rely on insulin injections to control your blood glucose levels. Insulin injections may be added while continuing the use of diabetes pills.
Insulin, because it can improve blood glucose control, often will lead to a better quality of life and prevent or delay the complications and side effects of diabetes.
Insulin is divided into categories which are based on:
- How fast they start to work
- When they reach the peak of their action
- How long they stay in your system
|Types of Insulin||Names of Insulin||How Fast They Start||When the Action Peaks||How Long They Last|
5 - 15 minutes
30 - 90 minutes
1 - 3 hours
3 - 5 hours
1/2 - 1 hour
2 - 4 hours
6 - 8 hours
1 - 2 hours
6 - 10 hours
10 - 16 hours
1 - 2 hours
No peak action
24 - 36 hours
There are also combination insulin mixtures that are premixed, such as:
- 75/25 mix: 75% NPH (intermediate-acting) and 25% Lispro (rapid-acting)
- 70/30 mix: 70% NPH and 30% Regular (short-acting)
- 50/50 mix: 50% NPH and 50% Regular
Each person responds differently to insulin. Your doctor will determine the best type of insulin and the best insulin schedule for you.
