Zepbound cost without insurance is $299 to $449 a month for most people paying cash through LillyDirect: $299 for the 2.5 mg starting dose, $399 for 5 mg, and $449 for 7.5 mg to 15 mg when you refill within 45 days.[1] The single-dose autoinjector pen has a much higher list price of $1,086.37 a month.[2]

Zepbound is tirzepatide, the same drug as Mounjaro. See our tirzepatide profile for how it works.
Zepbound self-pay prices by dose
Zepbound now comes in three forms: a single-dose vial, a four-dose KwikPen (one pen lasts a month), and a single-dose autoinjector pen.[1] For self-pay, Lilly prices the vial and KwikPen the same.[5]
| Dose | Vial or KwikPen, refilled within 45 days | Vial or KwikPen, regular price |
|---|---|---|
| 2.5 mg (starting dose) | $299 | $299 |
| 5 mg | $399 | $399 |
| 7.5 mg | $449 | $499 |
| 10 mg | $449 | $699 |
| 12.5 mg | $449 | $699 |
| 15 mg | $449 | $699 |
A month is 28 days: four vials or one KwikPen.[1] Lilly calls the lower price for 7.5 mg and up the Zepbound Journey Program. You get it automatically on your first purchase at those doses and keep it as long as each refill is bought within 45 days of the previous delivery.[3] Taxes and fees may be added.[1]
The label lists 5 mg, 10 mg and 15 mg as maintenance doses for weight management. The 2.5 mg dose is only for starting treatment, and a clinician sets the dose.[6] For the step-up schedule, see our tirzepatide dosage chart.
The single-dose pen and its list price
Lilly gives Zepbound’s list price as “$499 - $1,086.37 per fill,” based on wholesale prices accessed January 1, 2026.[2] The $1,086.37 figure is the familiar single-dose autoinjector pen, the version most insurers cover. Without insurance, that pen has no self-pay discount on LillyDirect; Lilly markets it to people whose commercial plan covers it.[1]
If you have commercial insurance that does not cover Zepbound, the savings card can bring the single-dose pen down to as low as $499 a month.[3] See our Zepbound savings card guide.
Supplies and how you get it
- Vials are sold only through LillyDirect and are self-pay only. You also need syringes and needles.[1]
- KwikPen self-pay pricing is available through LillyDirect and other pharmacies, and pen needles are sold separately.[3]
- Delivery: LillyDirect offers free home delivery or pickup at a retail pharmacy.[1]
- HSA and FSA: Lilly lists these purchases as HSA and FSA eligible, though this can vary by plan.[1]
A valid prescription for an approved use is required.[3] Zepbound is approved for weight management in adults with obesity, or overweight plus a weight-related condition, and for moderate to severe obstructive sleep apnea in adults with obesity.[6]
Vial, KwikPen or single-dose pen: which costs least?
If you are paying cash, the vial and the KwikPen cost the same each month, so the choice comes down to convenience and supplies:[1]
- Vial: you draw each weekly dose into a syringe yourself. You buy syringes and needles separately, and vials are available only through LillyDirect.
- KwikPen: one pen holds four weekly doses. You attach a new pen needle for each injection, and needles are sold separately. The KwikPen self-pay price is also offered at other pharmacies, not only LillyDirect.[3]
- Single-dose pen: the needle is built in and each pen is used once, but LillyDirect offers it with insurance pricing only, and its list price is $1,086.37, so it is rarely the cash option.[1][2]
The 45-day refill rule matters more than the form. Missing a refill window at 10 mg or higher raises the monthly price from $449 to $699, a $250 jump.[1] If you expect a gap, such as travel or a dose pause, ask the pharmacy how it affects your next price before you order. Lilly also offers post-purchase reimbursement for KwikPen buyers who refilled on time but did not get the discount at the counter.[3]
How Zepbound self-pay prices changed in 2025 and 2026
Self-pay prices have fallen several times:
- December 1, 2025: Lilly cut vial prices. The 2.5 mg vial went from $349 to $299 and 5 mg from $499 to $399. Higher doses went from $499 to $449 for on-time refills. At that point, late-refill prices were $599 to $1,049.[4]
- February 23, 2026: Lilly announced the four-dose KwikPen had been added to Zepbound’s label, and Lilly priced it the same as vials for self-pay, starting at $299.[5]
- October 2026: Late-refill prices are now $499 for 7.5 mg and $699 for 10 to 15 mg, lower than in December 2025.[1]
Yearly cost estimate
A year is 13 fills of 28 days. The dose schedule changes the total, because the label steps up by 2.5 mg at least every 4 weeks.[6]
| Scenario | Estimated yearly cost |
|---|---|
| 1 fill at 2.5 mg, 1 at 5 mg, then 11 at 7.5 to 15 mg (on time) | $5,637 |
| All 13 fills at 7.5 to 15 mg, on time | $5,837 |
| All 13 fills at 10 to 15 mg, late each time | $9,087 |
| 13 fills of single-dose pens at list price | $14,122.81 |
These are estimates before taxes, fees and supplies.
Other ways to pay less
- Commercial insurance: if your plan covers Zepbound, the savings card can bring the single-dose pen down to as little as $25 for up to a 3-month fill.[3] See does insurance cover Zepbound?
- Medicare: eligible Part D members can get the Zepbound KwikPen for $50 a month through the Medicare GLP-1 Bridge, which runs from July 1, 2026 through December 31, 2027. Vials and single-dose pens are not covered by the Bridge.[7] See does Medicare cover Zepbound?
- Lilly Cares: Zepbound is not on the Lilly Cares list of free medicines as of October 2026.[8] Our Zepbound patient assistance program guide covers alternatives.
