Many patients with Type 2 diabetes often require insulin to help reduce their blood sugars. Insulin is the hormone produced by the pancreas that is responsible for taking glucose (sugar) from the blood to the cells to use for energy. A person with Type 2 diabetes may need insulin if he is very insulin resistant, unable to control his blood sugars with oral medicine or, if he has had diabetes for an extended period of time, beta cells that make insulin can die off or become sluggish and injectable insulin may be required to help get blood sugars to goal level.


Often, people with diabetes start with a small amount of basal insulin to help get their blood sugars to goal. Basal insulin is meant to act as baseline or background insulin - its goal is to release a small amount of insulin over a 24 hour period. It is not used to lower mealtime sugars, but rather to help lower your blood sugars throughout the day. Two types of basal insulin are Lantus and Levemir. Both insulins are available in pen form as well as vial and syringe.

Lantus is losing patent protection and a cheaper generic version with not be available in the United States for another 30 more months. Companies are working on generic formulas of Lantus, which will likely be less costly. And while Lantus is still available for use, a more concentrated form of Lantus, Toujeo, has also hit the market. 

What is Toujeo and is it Meant for You?

Toujeo is three times more concentrated (300 units/ml) than Lantus, which makes the release of insulin slower and therefore may reduce the risk of hypoglycemia (low blood sugar).

Toujeo might be a good alternative for patients with hypoglycemia or insulin resistance requiring larger doses of insulin. However, unless you have had problems with hypoglycemia, there doesn't appear to be a good reason at this time to consider switching from Lantus to Toujeo. As for insurance coverage, Toujeo is now co-preferred on express scripts national formularies including Medicare part D and commercial plans (tier 3).


If you are currently using Lantus and are thinking about switching to Toujeo you can find more information about the insulin here:

You'll likely start with the same dose of Toujeo as Lantus and will discuss with your health care provider about adjusting your dose to get you to reach your target blood sugars. Some people may need larger doses of Toujeo than Lantus. Before making any decisions, discuss with your health care provider or certified diabetes educator if Toujeo is right for you. 

How is Toujeo Given? 

Similar to the Lantus SoloSTAR® prefilled pen, Toujeo SoloSTAR® is available via disposable prefilled pen which contains concentrated Lantus (glargine) insulin. The pen contains 450 units of insulin (as opposed to most pens that contain 300 units) and must be discarded 28 days after opening. Since is it more concentrated than Lantus, injection volume will be less when compared to that of Lantus SoloSTAR® pen. 

How Will I Inject Toujeo? 

Toujeo is to be administered using a pen device.
