As with all medications, the cost of Tresiba can vary. Factors that may affect the price you’ll pay include:

  • your treatment plan

In addition, you may need to purchase needles and syringes to use the vial form of Tresiba.

To find out what the cost of Tresiba will be for you, talk with your doctor, pharmacist, or insurance provider.

Note: If you have insurance, your insurance company may require prior authorization before it covers Tresiba. This means the company and your doctor will discuss Tresiba in regard to your treatment.

If a drug requires prior authorization but you start treatment without the prior approval, you could pay the full cost of the medication. You can ask your insurance company whether Tresiba requires prior authorization.

Tresiba contains the active drug insulin degludec, and it’s available only as a brand-name biologic drug. It doesn’t come in a biosimilar version. A biosimilar medication is a drug that’s similar to a brand-name biologic drug (the parent drug). Also, biosimilars tend to cost less than brand-name medications.


Biologic drugs can be expensive because of the research needed to test their safety and effectiveness. The manufacturer of a biologic drug can sell it for up to 12 years. When the biologic drug’s patent expires, multiple manufacturers can create biosimilar versions. This marketplace competition may lead to lower costs for biosimilars. Also, because biosimilars are very similar to biologic drugs, they don’t require the same costly testing.

If you take Tresiba long term, you may be able to lower its cost in the following ways.

Getting a 3-month supply

You may be able to get a 90-day supply of Tresiba. If approved by your insurance company, getting a 90-day supply of the drug could reduce your number of trips to the pharmacy and help lower the cost. If you’re interested in this option, check with your doctor, pharmacist, or insurance provider.

Using a mail-order pharmacy

Tresiba may be available through a mail-order pharmacy. Using this type of service may help lower the drug’s cost and allow you to receive your medication without leaving home. Some Medicare plans may help cover the cost of mail-order medications. You may also be able to get a 90-day supply of the drug via mail order.

If you don’t have health insurance, talk with your doctor or pharmacist. They may be able to suggest online pharmacy options that could work for you.
