Toujeo is a brand-name medication that contains insulin glargine, which is a biologic medication. (A biologic is a drug made from parts of living organisms.) It comes as a solution that you inject under your skin.

Toujeo isn’t available in a biosimilar version. (Biosimilars are like generic drugs. But unlike generics, which are made for nonbiologic drugs, biosimilars are made for biologic drugs.) Other brand-name drugs also contain insulin glargine, such as Rezvoglar and Semglee.

Frequently asked questions

Below are answers to some commonly asked questions about Toujeo and its dosage.

Does Toujeo have a recommended twice daily dosing?

No. Unlike some other forms of insulin, Toujeo is only recommended to be injected once daily around the same time each day. If you’re already using another long-acting insulin twice daily, your doctor will advise you how to safely switch to Toujeo once daily. Your total daily insulin dose may be different with Toujeo. But this is not worrisome as long as your blood sugar is well managed.

Talk with your doctor if you have questions about your Toujeo dosing.

Is Toujeo used long term?

Yes, doctors typically prescribe Toujeo as a long-term treatment. If you and your doctor determine that it’s safe and effective for your condition, you’ll likely use it long term.

If you have questions about how long you should use Toujeo, talk with your doctor.

How Toujeo is given

You’ll inject Toujeo under your skin once per day. Toujeo should be injected in your thigh, upper arm, or stomach area (abdomen). Rotate injection sites within a region to minimize irritation.

Your doctor may advise that you perform your Toujeo injections around the same time each day. This helps keep a consistent amount of the drug in your body. And that can help the drug work more effectively.

Be sure to talk with your doctor or pharmacist if you’re having difficulty using Toujeo. They can offer recommendations about how to do the injections.
