Zepbound Vials: What They Cost on LillyDirect and How to Order
A Zepbound single-dose vial holds one weekly dose of tirzepatide and costs $299 to $449 per month through LillyDirect self-pay, depending on dose. The $449 price for higher doses requires refilling within 45 days, and needles and syringes are sold separately.

A Zepbound vial is a small glass container that holds one weekly dose of tirzepatide, the same active ingredient as the Zepbound pen. Through LillyDirect’s self-pay channel, a one-month supply (four vials, 28 days) costs $299 for the 2.5 mg dose, $399 for 5 mg, and $449 for the 7.5, 10, 12.5, and 15 mg doses [3][4]. The $449 price for those higher doses depends on the Zepbound Self Pay Journey Program, which requires each refill to be purchased within 45 days of receiving the previous prescription [4]. To order, a prescriber sends an electronic prescription to LillyDirect Pharmacy, and a dispensing pharmacy contacts the patient to complete checkout [3].
The catches: vials are self-pay only, so no insurance is used [3]; needles and syringes are not included and must be bought separately [1][3]; and if a refill lands outside the 45-day window, the regular prices apply, which are currently $499 for 7.5 mg and $699 for 10, 12.5, and 15 mg [4]. Taxes and fees may apply on top of these prices, and HSA/FSA eligibility varies by plan [3].
What exactly is a Zepbound single-dose vial?
Each single-dose vial contains 0.5 mL of a clear, colorless to slightly yellow solution, and holds one once-weekly dose [1]. It comes in six strengths: 2.5, 5, 7.5, 10, 12.5, and 15 mg [1]. Vials are sold in cartons of 1 vial or 4 vials [1]. A monthly prescription is defined as 28 days and four once-weekly vials [3][4].
Unlike the single-dose pen, the vial has no built-in needle. It is drawn up and injected with a needle and syringe that the patient supplies [1][3].
Is the vial the same drug as the Zepbound pen?
Yes. According to Lilly, the pens and the vials have the identical active ingredient, tirzepatide, and are designed to deliver the same doses [2]. Based on bioequivalence studies, tirzepatide is expected to demonstrate comparable efficacy and safety across the different formulations [2].
There are small formulation differences. The single-dose vial and single-dose pen each contain one fixed 0.5 mL dose with no preservatives, while the multi-dose presentations use a 0.6 mL dosing volume and add the preservatives phenol and benzyl alcohol, plus glycerin as a tonicity agent [2].
Two things worth knowing. First, the Phase 3 SURMOUNT clinical trials for chronic weight management and obstructive sleep apnea were conducted using the single-dose pen, not the vial [2]. Lilly says it cannot make a specific recommendation on which presentation is best for each patient, and that the healthcare practitioner makes that decision [2].
How much do Zepbound vials cost on LillyDirect right now?
These are LillyDirect self-pay prices with terms and conditions, not list prices [3][4]. A month is defined as 28 days and four vials [3][4].
| Dose | LillyDirect self-pay price | Regular price (outside the Journey Program) |
|---|---|---|
| 2.5 mg | $299/month [3][4] | $299/month [4] |
| 5 mg | $399/month [3][4] | $399/month [4] |
| 7.5 mg | $449/month with the Journey Program [3][4] | $499/month [4] |
| 10 mg | $449/month with the Journey Program [3][4] | $699/month [4] |
| 12.5 mg | $449/month with the Journey Program [3][4] | $699/month [4] |
| 15 mg | $449/month with the Journey Program [3][4] | $699/month [4] |
The 2.5 mg and 5 mg doses are not part of the Journey Program offer; their $299 and $399 prices are the regular prices [4]. Lilly notes that the 2.5 mg dose is a starting dose and is not approved as a maintenance dose [3].
Separately, the list price, also called wholesale acquisition cost or WAC, is $499 to $1,086.37 per fill, based on AnalySource data accessed on January 1, 2026 [5]. WAC is the price at which Lilly sells to wholesalers, and what a patient pays at a pharmacy may be different [5]. Lilly’s direct-to-patient price is not the WAC, because the product is only available for purchase by cash-paying patients through that channel [5].
What is the Zepbound Self Pay Journey Program and the 45-day refill rule?
The Journey Program sets the price at $449 for each 1-month supply of the 7.5, 10, 12.5, and 15 mg Zepbound single-dose vial (or KwikPen) [4]. The $449 offer is applied automatically on the first purchase of those doses beginning February 23, 2026 [4].
To stay eligible, the refill purchase must be completed within 45 days of the delivery or receipt date of the previous prescription [4]. If the refill is completed more than 45 days after that date, the purchase offer does not apply, and the regular prices take over: $499 for 7.5 mg and $699 for 10, 12.5, and 15 mg [4].
Both new and existing patients are eligible, and a 1-month supply is defined as 28 days and four single-dose vials (or one KwikPen) [4]. Lilly may terminate, rescind, revoke, or amend the offer at any time, with or without notice, for any reason [4].
Why are vials cheaper than the pen?
Lilly has said the self-pay channel enables a transparent price by removing third-party supply chain entities and letting patients access savings directly, outside of insurance [6][7]. At launch in 2024, the vial prices were set at a 50% or greater discount compared with the list price of all other incretin (GLP-1) medicines for obesity, aimed at patients not eligible for the savings card program, those without employer coverage, and those who need to self-pay [6].
The vial is available exclusively through LillyDirect self-pay [3]. Lilly has framed the one-door distribution as a way to help protect the public from counterfeit, fake, unsafe, or untested knock-offs of its medications, with a multi-step verification process and a requirement for a valid, on-label electronic prescription from the patient’s healthcare provider [3][6].
How have vial prices changed since 2024?
The prices have come down several times, and higher doses were added in stages:
| Date | What changed |
|---|---|
| August 27, 2024 | Vials launched in 2.5 mg ($399/month, or $99.75 per vial) and 5 mg ($549/month, or $137.25 per vial); only those two doses [6] |
| February 25, 2025 | 7.5 and 10 mg vials added; Journey Program set them at $499/month (regular prices $599 and $699); 2.5 mg cut to $349, 5 mg to $499 [7] |
| June 16, 2025 | 12.5 and 15 mg vials announced; prescribable July 7, shipping early August; $499/month via the program, with regular prices of $849 and $1,049 [8] |
| October 29, 2025 | Walmart pickup announced, with pickup at Walmart pharmacies nationwide by mid-November; Walmart has nearly 4,600 pharmacies; same price as delivery; about 35% of new Zepbound prescriptions were fulfilled through LillyDirect in Q2 2025 [9] |
| December 1, 2025 | 2.5 mg cut to $299 (from $349), 5 mg to $399 (from $499), all other doses to $449 (from $499); regular prices at that time were $599, $699, $849, and $1,049 [10] |
| February 23, 2026 | KwikPen added at the same self-pay prices as vials; Lilly reported over 1 million patients accessed Lilly treatments through LillyDirect in 2025; current regular prices are $499 (7.5 mg) and $699 (10, 12.5, 15 mg) [11][4] |
The $599, $849, and $1,049 regular prices from 2025 are historical figures; the current regular prices per Lilly’s terms are $499 for 7.5 mg and $699 for the 10, 12.5, and 15 mg doses [4].
How do I order Zepbound vials?
The process starts with a prescription. A prescriber sends it to LillyDirect Pharmacy: NPI 1912889320, NCPDP 1574056, 1555 S Harding St, Ste 171-B68, Indianapolis, IN 46221 [3]. Prescription fulfillment through LillyDirect is open to all U.S. healthcare providers licensed to prescribe Lilly medicines, and LillyDirect is listed as a pharmacy option in all major electronic health record (EHR) systems [11][3].
Once the prescription is received, a dispensing pharmacy reaches out by text or email to guide the patient through the next steps, including verifying information, applying any available savings, and getting the medicine ready for checkout [3]. LillyDirect currently works with four dispensing pharmacies: Amazon Pharmacy, Fuze Health, Gifthealth, and Walmart Pharmacy. Which one fills the prescription depends on the medicine, the chosen delivery method, and the preferred payment method [3].
Patients choose between free home delivery or free pickup at Walmart Pharmacy [3]. For help with refills, the Journey Program, or questions about the medicine, LillyDirect has a patient line at 1-844-559-3471 [3].
Do Zepbound vials come with syringes and needles?
No. The vial has no built-in needle, and the supplies are sold separately [1][3]. The label instructs patients using vials to use a syringe appropriate for dose administration, such as a 1 mL syringe capable of measuring a 0.5 mL dose, and to always use a new syringe and needle for each injection [1].
Supplies can be purchased through LillyDirect checkout, at a local pharmacy, or online [3]. KwikPen needles are different from the needles required for the vial; the KwikPen needs a new pen needle for each weekly injection [3].
Before each use, the label says to inspect the medicine visually: it should appear clear and colorless to slightly yellow, and it should not be used if particulate matter or discoloration is seen [1]. The label also says not to share needles or syringes with other people [1].
Can I use insurance, a savings card, or Medicare for vials?
The single-dose vial is self-pay only through LillyDirect [3]. For comparison, the KwikPen self-pay savings card is for cash-paying patients who agree not to seek reimbursement from insurers or government programs and not to apply the costs toward any deductible [4].
The single-dose pen works differently: it is the insurance-channel option, and Lilly says it could be the most cost-effective option for patients with commercial insurance that covers it who also meet the savings card eligibility requirements [3]. That card, for commercially insured patients with coverage, brings the cost to as low as $25 for a 1-, 2-, or 3-month fill, with maximum savings of $100 per month and $1,300 per calendar year; the card expires on December 31, 2026 [4]. Government beneficiaries, including Medicaid, Medicare, VA, and TRICARE patients, are excluded from the savings card [4][12].
For Medicare patients, the Medicare GLP-1 Bridge program starts July 1, 2026, and sets the cost at $50 per month for eligible patients [14]. The Bridge covers the Zepbound KwikPen only; the single-dose pen and the vials are not covered [14]. The Medicare fact sheet lists four eligibility requirements that must all be met: Medicare Part D drug coverage (standalone or through a health plan that includes drug coverage), age 18 or older, specific BMI thresholds — 35 or higher; 30 or higher with certain types of heart failure, hard-to-control high blood pressure, or stage 3a or above chronic kidney disease; or 27 or higher with prediabetes or a prior heart attack, stroke, or blocked arteries — and not having type 2 diabetes, moderate-to-severe sleep apnea, or fatty liver disease. Patients already receiving a GLP-1 drug paid for by their Medicare drug plan are also not eligible [14]. The $50 payment does not count toward the Medicare drug plan deductible or the yearly out-of-pocket limit [14].
How should I store Zepbound vials?
The label says to store single-dose vials in a refrigerator at 2°C to 8°C (36°F to 46°F), in the original carton, protected from heat and light [1]. If needed, a vial can be kept unrefrigerated at temperatures not exceeding 30°C (86°F) for up to a total of 21 days, and it must be discarded after a total of 21 days at room temperature [1].
Zepbound should not be frozen, and it should not be used if it has been frozen [1].
The multi-dose vial and KwikPen have different rules: unopened, they can be stored at room temperature (up to 30°C/86°F) but must be thrown away after 30 days; once opened, the label says to throw them away after a total of 30 days at room temperature, 30 days after first use, or after four weekly doses, even if medicine is left [1].
Vial vs. KwikPen vs. single-dose pen: what’s the difference?
The KwikPen is a multi-dose device that holds four fixed 0.6 mL doses, one per week, for a full month in one pen [13]. After the fourth dose, the pen locks and prevents dialing another full dose; the label says not to inject leftover medication and not to transfer it into a syringe, and to throw the pen away 30 days after first use even if medicine remains [13]. The KwikPen is not recommended for self-administration by people who are visually impaired, per the label [1].
The single-dose pen has a built-in needle that the patient never has to see or handle, and it is the insurance-channel option [3]. The vial requires drawing the dose with a separate needle and syringe and is self-pay only through LillyDirect [1][3].
LillyDirect itself is Eli Lilly’s direct-to-patient channel; it works with licensed third-party dispensing pharmacies to fill prescriptions and sells select Lilly medicines only [3][7]. Which presentation fits a given patient is a decision for the prescriber; Lilly states it cannot recommend one presentation over another [2].
