Question 1

Why Is Toujeo So Expensive?

Accepted Answer

Toujeo is expensive because it is a brand-name biologic insulin (insulin glargine) and does not have a lower-cost biosimilar version available. Since biosimilars usually cost less than brand-name biologics, the lack of competition keeps Toujeo’s price high.

Question 2

Can You Take Metformin and Toujeo Together?

Accepted Answer

Yes, metformin and Toujeo can be taken together, but the combination can increase the risk of low blood sugar (hypoglycemia). Your doctor may adjust your dose or recommend closer blood sugar monitoring to ensure safe use.

Question 3

How Long Can You Use a Toujeo Pen?

Accepted Answer

A Toujeo pen can be used for up to 56 days after first use when kept at room temperature. After 56 days, it should be discarded, even if insulin remains.

Question 4

Is Toujeo Hard on the Kidneys?

Accepted Answer

Toujeo is not directly harmful to the kidneys, but in people with kidney problems, it can increase the risk of low blood sugar. Patients with kidney disease may need closer blood glucose monitoring and possible dose adjustments.

Question 5

Can Toujeo Make You Gain Weight?

Accepted Answer

Toujeo is not approved by the FDA specifically to cause weight gain. However, some people may notice weight gain while using it, which can happen with insulin treatment.

Question 6

Which Is Better, Lantus or Toujeo?

Accepted Answer

Both Lantus and Toujeo are long-acting insulins used to control blood sugar, but they differ in strength and duration. Lantus contains 100 units/mL of insulin and usually works for about 24 hours. Toujeo is more concentrated at 300 units/mL and can last up to 36 hours.
