Product Details


Toujeo is a Type 2 diabetes insulin that is a manmade long-acting insulin used for diabetes mellitus treatment and promoting better blood sugar control. Toujeo can be used to treat either Type 1 or Type 2 diabetes and it is given as a once-daily injection. Toujeo insulin works by partly replacing the body’s natural production of insulin to help move glucose into cells and helping them with getting the sugar they need. It also helps stabilize blood sugar levels and will commonly be used in conjunction with other medication, including Metformin for Type 2 diabetes.

Injection may be made into one of 3 acceptable injection sites: back of upper arms / abdomen (excluding 2” radius around navel) / thighs.

Switch to a different injection site for each day’s injection, alternating between the 3 of them at all times to prevent the chance of lipodystrophy.
