What pushes the price up
| What | Why it matters |
|---|---|
| Form | A 10 mL vial, a box of 100 unit pens and a box of 200 unit pens all have different prices. Check which one your doctor ordered. |
| Pharmacy | With a SingleCare coupon, a 10 mL vial ranges from $94.22 at Kroger to $116.84 at CVS, so the store matters. |
| Coupon or card | SingleCare says its coupon cuts the $394.56 retail price by about 76 percent. Without a coupon, you may pay far more. |
| Insurance | With commercial insurance, the maker says you may pay as little as $35 for a 30 day fill. Cash buyers do not get that offer. |
| Dose | Your daily units decide how many vials or pens you use each month. A higher dose means you refill more often. |
What the price includes
The price is for insulin degludec in a vial or a box of FlexTouch pens. It does not include pen needles, test strips, a glucose meter or the doctor visit. Needles and supplies are bought apart. A box of pens or a vial may last you less than a month at a high dose. It does not include tax or extras the provider adds on the day.
Does insurance cover it
GoodRx says Tresiba is covered by most Medicare and insurance plans. Your cost depends on your plan, your deductible and the drug tier. With commercial insurance, the Novo Nordisk savings offer may bring your cost to as little as $35 for a 30 day fill. If you have no coverage, or a high copay, ask the pharmacist about the maker's other programs. Use a discount coupon only after you compare it with your insurance copay, since you often pick one or the other for each fill. Ask your plan if prior approval is needed.
When a doctor orders it
Tresiba is a long acting insulin. A doctor orders it for people with diabetes who need insulin to control blood sugar. It is a prescription drug, and it is not sold over the counter. Your doctor picks the dose after blood tests and talks with you about your daily habits. Never change your dose on your own. If cost is a problem, tell your doctor and pharmacist, since there are savings programs.
How to judge your quote
- Ask for the price of the exact form you need: vial, 100 unit pens or 200 unit pens.
- Compare the coupon price at two or three pharmacies, since one vial ranged from $94.22 to $116.84.
- Ask how many days the box will last at your dose so you can compare cost per month.
- Ask if you qualify for the maker's $35 offer or the MyInsulinRx program.
- Compare the total with the range above: $88 to $395 per vial or box of pens for most people in 2026.
Ways to pay less
- Compare GoodRx, SingleCare and Drugs.com prices. One 10 mL vial ranged from $94.22 to $394.56 in these sources, so the coupon matters a lot.
- Ask about the Novo Nordisk savings offer. Drugs.com says insured patients may pay as little as $35 for a 30 day fill.
- Ask about the MyInsulinRx program, which Drugs.com says gives a monthly supply of Novo Nordisk insulin for $35.
- If money is tight, ask about the free one time supply voucher for patients with hardship, which Drugs.com says is limited to once a year.
- Ask your doctor if a different insulin could fit you. Some insulins cost less, but never switch without your doctor.
