What is Toujeo?
Toujeo contains insulin, called "insulin glargine". This is modified insulin very similar to human insulin. Toujeo contains three times more insulin in 1 ml than standard insulin-containing 100 units/ml.
How does it work?
The main activity of insulin, including insulin glargine, is the regulation of glucose metabolism. Insulin and its analogues reduce blood glucose levels by stimulating peripheral glucose uptake, which is primarily responsible for skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis in adipocytes, inhibits proteolysis, and increases protein synthesis.
What are the benefits of taking it?
Toujeo Insulin uses include being indicated in the treatment of diabetes mellitus in adults, adolescents, and children from 6 years. Diabetes mellitus is a disease in which your body does not make enough insulin to control the level of sugar in your blood. Toujeo reduces your blood sugar level steadily over a long period of time. One dose is used once a day. If you need to, you can change the time of your injection because this medicine reduces your blood sugar level for a long period of time.
How do I use it and its dosage?
Always use this medicine exactly as your doctor has told you. If in doubt, ask your doctor, pharmacist, or nurse again.
Although Toujeo contains the same active substance as insulin glargine 100 units / ml, these medicines are not interchangeable. Moving from one insulin treatment to another requires a prescription, medical supervision, and blood glucose monitoring. For more information, you consult with your medic.
How much to use
The Toujeo SoloStar pre-filled pen can deliver doses of 1 to 80 units in one injection, in steps of 1 unit.
The dose window of the SoloStar pen shows the number of Toujeo units to inject. Do not readjust the dose.
Depending on your lifestyle, blood sugar checks, and your previous insulin, your doctor will tell you:
- How much Toujeo do you need each day and at what time.
- When to check your blood sugar level and if you need to have a urinalysis.
- When you may need higher or lower doses.
Toujeo is a long-acting insulin. Your doctor may tell you to use it with short-acting insulin or other medicines for high blood sugar.
If you use more than one insulin, always check that you are using the correct insulin by checking the insulin label before each injection. Medication errors have been reported due to confusion between insulins, particularly between long-acting and fast-acting insulins. The "300" does is highlighted in gold on the label of your Toujeo SoloStar pre-filled pen. Ask your doctor and pharmacist if you have questions.
Flexibility in administration time
- Use Toujeo once a day, preferably at the same time each day.
- When needed, it can be injected up to 3 hours before or after the normal time of use.
Use in elderly patients (65 years and older)
If you are 65 years of age or older, tell your doctor as you may need a lower dose.
If you have kidney or liver problems, tell your doctor as you may need lower doses.
How to inject
Toujeo is injected under the skin (subcutaneously or "SC"). Inject it into the front of your thighs, the upper part of your arms, or the front of your waist (abdomen). Change the injection site within an injection area each day. This will reduce the risk that the skin will shrink or thicken.

Toujeo is a long-acting insulin designed to be used once a day. It starts to work within 6 hours, making it slower acting than some other insulins. It provides a steady insulin release over 24 hours to help maintain stable glucose levels. The full effects of Toujeo may take a few days to adjust to, so regular blood glucose monitoring is essential, especially when transitioning from another diabetes injection.
Both insulins contain the same active ingredient but differ in concentration and absorption. Toujeo contains 300 units/ml, whereas Lantus contains 100 units/ml, making Toujeo more concentrated and longer-lasting. This medication provides smoother glucose control with a lower risk of hypoglycaemia compared to Lantus. Most people prefer Toujeo because it allows more flexibility in dosing.
This medication is used to manage both type 1 and type 2 diabetes by providing a steady release of insulin over 24 hours. This helps regulate blood sugar levels by allowing glucose to be absorbed more effectively. Unlike short-acting insulins, which work quickly after meals, Toujeo maintains consistent insulin levels throughout the day and night, reducing fluctuations that can lead to hyperglycaemia or hypoglycaemia.
- Monitor blood sugar levels regularly to prevent low or high blood sugar episodes.
- Never mix Toujeo with other insulins or solutions, as it has a unique formulation.
- Rotate injection sites to avoid skin thickening (lipodystrophy).
- Inform your healthcare professional if you have kidney or liver disease, as this may affect insulin metabolism.
- Avoid alcohol consumption, as it can increase the risk of low blood sugar episodes.
- Pregnancy and breastfeeding: Consult your healthcare professional if you are pregnant or planning to conceive while using Toujeo.
Toujeo is normally prescribed for adults and children aged 6 and above who have diabetes and need long-acting insulin to regulate their blood sugar levels. It is suitable for type 1 diabetes patients who require basal insulin support alongside fast-acting insulin, type 2 diabetes patients who need long-acting insulin to manage persistent high blood sugar, and individuals switching from other basal insulins (such as Lantus) under medical supervision.
Yes, Toujeo can be used alongside other diabetes medications, such as fast-acting insulins, oral diabetic medications, and weight loss injections.
