What Is Insulin Glargine Used For?

Insulin glargine is primarily used for controlling blood sugar levels in adults and children. Specific insulin glargine uses include treating type 2 diabetes in adults and type 1 diabetes in adults and children (age six and older). As a long-acting insulin medication, it can provide a steady level of insulin throughout the day. Off-label insulin glargine uses include treating type 2 diabetes in children and gestational diabetes.

What Is Insulin Glargine Used For? -- An Overview

Insulin glargine (Lantus®) is a form of insulin used to help control blood sugar in people with type 1 or type 2 diabetes. This is a long-acting medication and is injected just once a day.

Insulin Glargine Uses for Type 2 Diabetes

Type 2 diabetes is sometimes called adult-onset diabetes or non-insulin-dependent diabetes. Type 2 diabetes is common -- much more common than type 1 diabetes. The cause of type 2 diabetes is not fully understood, although it is known that obesity and genetics play important roles.
Unlike type 1 diabetes, type 2 diabetes occurs when the pancreas fails to produce enough insulin, at least initially. The problem with type 2 diabetes is that the cells of the body do not respond to insulin as well as they normally should. As a result, the cells do not remove sugar (glucose) from the blood very well, resulting in high blood sugar levels (hyperglycemia).
Over time, high blood sugar levels (whether from type 1 or type 2 diabetes) can lead to a number of problems, including diabetic impotence, diabetic neuropathy, kidney failure, and heart disease (see Diabetes Complications). Eventually, the pancreas may also become damaged from having to produce so much insulin over a long time. People with damage to the pancreas need to take insulin, as the pancreas can no longer produce enough of it.
Many people with type 2 diabetes may only need to use a long-acting insulin, such as insulin glargine, in addition to any oral diabetes medications they may take. However, some people with advanced type 2 diabetes may also need a short- or rapid-acting insulin to help control the sudden rise in blood sugar levels that occurs after meals.
A balanced treatment plan for type 2 diabetes should include a diet and exercise plan (see Diabetic Diet and Diabetes and Exercise). Talk to your healthcare provider about any dietary or exercise changes you should make.
