Mounjaro coupon: how Lilly’s $25 savings card works

The Mounjaro coupon is Eli Lilly’s own Mounjaro savings card. If your commercial insurance covers Mounjaro, it can bring a 1, 2 or 3-month fill of the single-dose pen down to $25, with savings capped at $150 a month, until December 31, 2026. If your plan doesn’t cover it, the same card sets a $499 monthly price, which is also what LillyDirect charges people with no insurance. Medicare and other government plan members can’t use the card at all.

Everything below comes from Lilly’s savings page and full card terms, LillyDirect and Lilly’s pricing page, read on October 27, 2026. Lilly can change or end the card at any time, so check its terms before each refill.

The card works only for the single-dose pen. Lilly’s terms list its six pen NDCs and say other forms “are not eligible for Program savings.”

The $25 savings card for people with coverage

Lilly’s terms say you must have “commercial drug insurance that covers Mounjaro” and “a prescription for an approved use consistent with FDA-approved product labeling to pay as little as $25 for a 1-month, 2-month, or 3-month prescription fill.” To use the card, the terms also require that you:

• Live in the US or Puerto Rico and are 18 or older.
• Aren’t enrolled in any state, federal or government-funded program, which Lilly lists as Medicaid, Medicare, Medicare Part D, Medicare Advantage, Medigap, DoD, VA, TRICARE/CHAMPUS or any state prescription drug assistance program.
• Sign a HIPAA authorization and activate the card.

The Mounjaro label approves it for blood sugar control in adults and children 10 and older with type 2 diabetes, and for lowering the risk of heart attack, stroke and cardiovascular death in adults with type 2 diabetes at high risk. Those are the uses the card covers.

How the $150 cap works

You pay as little as $25, but the card pays at most $150 toward a 1-month fill, $300 toward a 2-month fill and $450 toward a 3-month fill, and no more than $1,950 in a calendar year. You can use it for up to 13 fills a year. Lilly defines a month as 28 days and up to 4 pens; 3 months is 84 days and up to 12 pens. So:

• If your plan’s share for a month is $175 or less, you pay $25.
• If your share is $400 a month, the card pays $150 and you pay $250.
• If you reach the $1,950 yearly cap, you pay your plan’s full share for the rest of the year.

A high deductible is the usual reason people pay more than $25. Ask your plan what you’d owe for Mounjaro before and after the deductible is met.

Plans that can block it

Lilly excludes plans in an “alternate funding program,” where coverage or your costs depend on whether a maker’s copay program exists. Lilly also says it may reduce or end your savings if your plan only partly covers Mounjaro, requires you to use the card, or doesn’t count card payments toward your copay, deductible or coinsurance. You can’t seek reimbursement for the savings from your insurer, a health savings account or a flexible spending account.

How to get Mounjaro for $25

Lilly’s own steps, put plainly:

1. Get the card on Lilly’s savings page by answering its eligibility questions, then activate it.
2. Ask your prescriber whether a 3-month prescription makes sense. Lilly says eligible patients can pay as little as $25 for the whole 3-month fill.
3. Call your pharmacy and ask whether it will fill a 3-month prescription. If it fills only 1 month, Lilly suggests moving the prescription to another in-network pharmacy.
4. Call your insurer and ask about limits on 3-month fills. If your plan doesn’t allow them, the card still works on a 1-month fill.
5. Plan for stock. Lilly says some pharmacies may not have 3 months on hand but usually restock daily and can fill within 1 to 2 business days.

Mounjaro coupon without insurance

There are two routes, and both land at $499 a month.

• Commercial insurance that doesn’t cover Mounjaro: the card brings a 1-month fill of the single-dose pen to as low as $499. Savings are capped at $647 a month and $8,411 a year, for up to 13 fills, and this part of the card also ends on December 31, 2026.
• No insurance at all: LillyDirect lists the single-dose pen at “Starting at $499/month” self-pay at 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg and 15 mg. Your prescriber sends the prescription to LillyDirect Pharmacy, a pharmacy partner contacts you, and you can choose home delivery or pickup. LillyDirect says it is FSA and HSA eligible, depending on your plan.

The price doesn’t change as your dose goes up. For comparison, Lilly lists Mounjaro at $1,112.16 per fill of 4 pens (Lilly). That list price is what Lilly charges wholesalers, not what a cash buyer at LillyDirect pays. Our Mounjaro cost guide works out what a year costs.

Medicare and other government plans

Lilly’s card excludes you, but Part D usually does more of the work. Lilly says Mounjaro “is covered on many Medicare Part D plans for type 2 diabetes,” and that about 8 in 10 Part D patients pay $0 to $50 for a 28-day supply, with the rest averaging about $262. Lilly bases that on IQVIA data from October 2024 to September 2025. It also points Part D enrollees to the Medicare Prescription Payment Plan to help manage monthly pharmacy costs.

The Medicare GLP-1 Bridge, the $50 program that runs from July 1, 2026 to December 31, 2027, doesn’t include Mounjaro. Its prior authorization form sends anyone with type 2 diabetes to their regular Part D plan and lists only Foundayo, Wegovy and the Zepbound KwikPen for weight reduction.

Medicaid, VA and TRICARE coverage depends on your plan and state. Our guide to whether insurance covers GLP-1s goes through each.

Using Mounjaro for weight loss

Mounjaro is approved for type 2 diabetes, so a prescription for weight loss alone is off-label, and Lilly’s card requires an approved use. The same molecule, tirzepatide, is sold for weight loss as Zepbound, which the Zepbound label approves for long-term weight reduction in adults with obesity, or overweight with a weight-related condition, and for moderate to severe obstructive sleep apnea in adults with obesity.

Zepbound has its own offers. With commercial coverage for the single-dose pen, Lilly’s Zepbound card can bring a fill to $25, with savings capped at $100 a month and $1,300 a year, also ending December 31, 2026 (Lilly). Without coverage, LillyDirect sells Zepbound vials and the KwikPen for $299 at 2.5 mg, $399 at 5 mg and $449 at 7.5 mg to 15 mg if you refill within 45 days. Late refills cost $499 at 7.5 mg and $699 at 10 mg to 15 mg. Our Zepbound coupon guide has the full terms, and Mounjaro vs Zepbound covers the differences beyond cost.

Both drugs carry the same boxed warning. In rats, tirzepatide caused thyroid C-cell tumors, and it is unknown whether it causes them, including medullary thyroid carcinoma (MTC), in people. Neither is for anyone with a personal or family history of MTC or with MEN 2.

Discount cards and program prices

Lilly’s terms are blunt: card savings “cannot be combined or utilized with any other program, discount, discount card, cash discount card, coupon, incentive, or similar offer involving Mounjaro.” A pharmacy discount card and Lilly’s card can’t both apply to one fill, so compare the two prices and use one.

Online programs that prescribe Mounjaro set their own prices, and many add a membership. As of October 2026:

• Mochi Health lists Mounjaro “as low as $499,” with its membership billed on top.
• Found lists Mounjaro at about $1,100 a month, plus its Branded GLP-1 Plan fee of $149 per 28-day cycle.
• Eden lists Mounjaro at $1,399 a month, plus its $99 monthly membership.
• Hims lists Mounjaro at $1,899 a month, with its membership billed separately.

A program charging well above $499 isn’t passing on LillyDirect’s self-pay price. Ask which pharmacy fills your prescription and at what price before you join. Our tirzepatide provider rankings and insurance rankings list the programs we track.

The bottom line

The real Mounjaro coupon is Lilly’s savings card. With commercial coverage and a type 2 diabetes prescription, it can cut a 1, 2 or 3-month fill to $25, up to $150 off a month and $1,950 a year, until December 31, 2026. Without coverage, the card and LillyDirect both put Mounjaro at $499 a month. Medicare Part D enrollees can’t use the card but usually pay through their plan. If you’re after weight loss, ask a licensed clinician about Zepbound, which is approved for it.
