How Much Does Mounjaro Cost? (2026 Pricing Guide)

Mounjaro List Price

Mounjaro (tirzepatide injection) is Eli Lilly's once-weekly dual GLP-1/GIP receptor agonist, FDA-approved for type 2 diabetes. In the SURPASS-2 trial (NEJM 2021) it lowered A1C and body weight more than semaglutide 1 mg at every dose. Lilly's wholesale acquisition cost (list price) is $1,112 per monthly fill at every dose, 2.5 mg through 15 mg (pricinginfo.lilly.com).

That is $237 a month below Wegovy's $1,349 list price and $26 above Zepbound's $1,086. Very few people pay list: insurance, the Lilly savings card and LillyDirect all bring it down.

How Much Is Mounjaro Without Insurance?

Without insurance Mounjaro costs $499 a month through LillyDirect, Lilly's own online pharmacy, and the price is the same at every dose (read October 13, 2026). Your doctor sends the prescription to LillyDirect Pharmacy and a dispensing partner ships the pens. At a retail pharmacy with no coverage you pay up to the $1,112 list price.

Unlike Zepbound, Mounjaro has no cheaper starting-dose tier on LillyDirect: the 2.5 mg starter pen is $499, the same as 15 mg.

Lilly Savings Card Terms (2026)

The Mounjaro savings card is for commercially insured patients only and has two tiers:

• Insurance covers Mounjaro: as little as $25 for a 1-, 2- or 3-month fill. Savings are capped at $150 per 1-month fill and $1,950 per calendar year.
• Insurance doesn't cover Mounjaro: as low as $499 a month. Savings are capped at $647 a month and $8,411 a year.
• Not eligible: anyone enrolled in Medicare, Medicaid or another state, federal or government-funded program.
• Expiry: the card expires and savings end on December 31, 2026.

Because the covered tier caps savings at $150 a month, a plan copay above about $175 leaves you paying the difference. Terms are from mounjaro.lilly.com, read October 13, 2026.

Zepbound: Same Drug, Weight Loss Label

Zepbound is the same molecule as Mounjaro (tirzepatide), approved for chronic weight management. In SURMOUNT-1 (NEJM 2022), adults without diabetes on the 15 mg dose lost an average of 20.9% of body weight over 72 weeks. Lilly prices it differently:

• Zepbound list price: $1,086/month
• LillyDirect self-pay: $299 at 2.5 mg, $399 at 5 mg, $449 at 7.5–15 mg (the higher doses need a refill within 45 days; vials and KwikPens)
• Zepbound savings card: as little as $25/month with commercial coverage

Mounjaro with Insurance and Medicare

Coverage for Mounjaro is usually better than for weight-loss drugs because its approved use is type 2 diabetes. Expect prior authorization (often a documented A1C and a tried first-line drug such as metformin), and most plans will not cover Mounjaro prescribed off-label for weight loss.

• Commercial insurance that covers it + savings card: from $25
• Commercial insurance that doesn't cover it + savings card: $499
• Medicare Part D or Medicaid: your plan's copay for type 2 diabetes; the savings card can't be used.

The Medicare GLP-1 Bridge, which launched July 1, 2026 at a $50 copay, covers Wegovy, Zepbound and Foundayo for eligible beneficiaries — not Mounjaro. Details: Medicare GLP-1 coverage 2026. If a plan denies Mounjaro, ask whether Zepbound is covered under its obesity benefit instead.

Is There an Oral Mounjaro?

No. Tirzepatide is injection-only. If you want a pill, the FDA-approved options are Lilly's Foundayo (orforglipron, approved April 1, 2026) and Novo Nordisk's Wegovy pill (oral semaglutide), both from $149 a month self-pay at the starting doses. See Foundayo price and dosing.
