Zepbound Vials: Cost, Instructions, and Vials vs KwikPen

October 29, 2026 · 7 min read · By the Sharpy team
The short answer

Zepbound vials are single-dose glass vials of tirzepatide that Eli Lilly sells only through LillyDirect, self-pay only. On October 29, 2026, Lilly listed $299 a month for 2.5 mg, $399 for 5 mg and $449 for 7.5 mg to 15 mg if you refill within 45 days, the same as the KwikPen. Each vial holds one 0.5 mL weekly dose, and you buy your own 1 mL syringes and needles. Whichever form you use, Sharpy helps you keep muscle on Zepbound with one protein target and one 20-minute workout a day.

Zepbound vials are the version of Zepbound (tirzepatide) you draw up with a syringe instead of clicking a pen. People search for them for one main reason: price. Here is the short answer. Lilly sells single-dose Zepbound vials only through LillyDirect, self-pay only, for $299 to $449 a month if you refill on time. Each vial holds one weekly 0.5 mL dose. You buy your own syringes and needles. We checked every price below on Lilly's LillyDirect Zepbound page on October 29, 2026, and every dosing and storage fact against the FDA label revised in August 2026.

Zepbound vials cost by dose

LillyDirect sells vials in packs of 4, one per week. Lilly defines a "month" as 28 days and 4 vials.

Vial strength Self-pay price (refill within 45 days) Regular price (refill after 45 days)
2.5 mg/0.5 mL (starting dose) $299 $299
5 mg/0.5 mL $399 $399
7.5 mg/0.5 mL $449 $499
10 mg/0.5 mL $449 $699
12.5 mg/0.5 mL $449 $699
15 mg/0.5 mL $449 $699

Three things in the fine print matter:

  • The $449 price depends on the Zepbound Journey Program. You keep it by refilling within 45 days.
  • Needles and syringes are extra. Lilly's page says a "needle and syringe purchase required" for every vial strength.
  • 2.5 mg is only a starting dose. The label says it is not approved as a maintenance dose. Your prescriber decides when to move up.

Because a month is 28 days, you buy about 13 packs a year, not 12. At $449, that is about $5,837 a year before syringes. For the full ordering process, partner pharmacies and the LillyDirect address your doctor needs, see our LillyDirect Zepbound guide.

Are Zepbound vials cheaper than pens?

They used to be. Since Lilly added the multi-dose KwikPen to its self-pay menu, the KwikPen and vials have the same price at every dose. So the choice is now about how you want to inject, not about saving money. For the card rules that set those KwikPen prices, see our Zepbound KwikPen coupon guide.

Zepbound vials vs KwikPen vs single-dose pen

Single-dose vial KwikPen Single-dose pen
Doses in a box 4 vials, 1 dose each 1 pen, 4 weekly doses 4 pens, 1 dose each
Volume per dose 0.5 mL 0.6 mL 0.5 mL
How you dose Draw into a syringe Dial and press Press, auto-injects
Needle Buy syringe and needle Buy pen needles Built in
Insurance Self-pay only Select insurance or self-pay Insurance
Where LillyDirect only LillyDirect and pharmacies LillyDirect and pharmacies
Out of the fridge Up to 21 days total, at or below 86°F Up to 30 days Up to 21 days total

Some practical differences:

  • Vials take more steps. You pull air into the syringe, push it into the vial, draw the medicine back out and check the line. Some people find this easy. Others find it fiddly, especially at first.
  • Vials are a single dose. The carton says "Discard unused portion." There is no saving leftover liquid for later.
  • Vision matters for the KwikPen. The FDA label says the KwikPen is not recommended for self-injection by people who are visually impaired. If reading small lines is hard for you, ask your prescriber which form fits best.

The medicine inside is the same tirzepatide in every form. If you are moving from Mounjaro or wondering why the same drug has two names, see Zepbound vs Mounjaro. Our Mounjaro dosage chart shows the label dose steps that Zepbound shares.

Zepbound vials instructions: how to inject, step by step

This is a plain-English summary of the FDA-approved Instructions for Use for the single-dose vial. It is not a substitute for training. The label says your healthcare provider should show you how to inject before your first dose, and again if your Zepbound form changes.

What you need: 1 Zepbound vial, 1 new syringe and needle (for example a 1 mL syringe, as your provider recommends), 1 alcohol swab, gauze, and a sharps container.

  1. Check the vial. Make sure it is the right medicine and dose, and not expired. The liquid should be clear and colorless to slightly yellow, not cloudy, not frozen, with no particles.
  2. Wash your hands. Pull off the plastic cap. Leave the rubber stopper on. Wipe the stopper with the alcohol swab.
  3. Attach the needle to the syringe if it is not already attached, then pull off the needle shield.
  4. Draw in 0.5 mL of air. Pull the plunger to the 0.5 mL line.
  5. Push the air into the vial. Put the needle through the stopper and push the plunger all the way in.
  6. Draw up the medicine. Turn the vial and syringe upside down, keep the needle tip in the liquid, and pull past the 0.5 mL line. Tap out bubbles, then push the plunger back to exactly 0.5 mL.
  7. Inject under the skin of your stomach or thigh (someone else can use the back of your upper arm). Push the plunger down and keep the needle in for at least 5 seconds.
  8. Throw the needle and syringe into a sharps container. Do not recap the needle.

The label also says to rotate your injection site every week, and not to inject into skin that is tender, bruised, scarred, thickened or lumpy. If you get redness or bumps, our injection site reactions guide covers what is normal and when to call your doctor.

How do you store Zepbound vials?

Per the FDA label:

  • Keep vials in the refrigerator at 36°F to 46°F (2°C to 8°C), in the original carton to block light.
  • If needed, a single-dose vial can stay out of the fridge at up to 86°F (30°C) for a total of 21 days. After that, throw it away.
  • Never freeze Zepbound. Do not use a vial that has been frozen.

What about the Zepbound multi-dose vial?

The August 2026 FDA label lists a second vial: a multi-dose vial with 2.4 mL, enough for four weekly 0.6 mL doses. Its rules are different. You throw it away 30 days after first use, after 4 doses, or after 30 days at room temperature, whichever comes first, even if medicine is left. On October 29, 2026, LillyDirect's Zepbound page listed only the single-dose vial, so if you are handed a multi-dose vial, read its own Instructions for Use. The dose volume (0.6 mL) is not the same as the single-dose vial (0.5 mL).

Zepbound vials NDC numbers

Your pharmacist uses these codes. They come from the How Supplied section of the FDA label.

Strength 4-pack single-dose vial NDC
2.5 mg/0.5 mL 0002-0152-04
5 mg/0.5 mL 0002-0243-04
7.5 mg/0.5 mL 0002-1214-04
10 mg/0.5 mL 0002-1340-04
12.5 mg/0.5 mL 0002-1423-04
15 mg/0.5 mL 0002-2002-04

Brand-name Zepbound vials have a Lilly label and an NDC starting with 0002. Vials sold online as "tirzepatide" without that label are not Zepbound. Recent recalls hit compounded tirzepatide vials, not Lilly's product, as our tirzepatide recall guide explains.

Where to buy Zepbound vials

  • LillyDirect only. Lilly says the vials are "exclusively available through LillyDirect." Your prescriber sends the prescription to LillyDirect Pharmacy.
  • Delivery or pickup. LillyDirect lists free delivery and pickup. Walmart Pharmacy is one of its partner pharmacies.
  • No insurance, but maybe HSA or FSA. Vials are self-pay only. Lilly lists them as HSA/FSA eligible, but that varies by plan.
  • Need a prescriber? LillyDirect links to independent telehealth services such as the one in our Counsel Health GLP-1 guide.
  • On Medicare? The $50 Medicare GLP-1 Bridge covers the KwikPen, not vials.

Getting your money's worth from each vial

At up to $449 a month, the goal is to lose fat, not the muscle that keeps your metabolism up. In the SURMOUNT-1 body composition substudy, about a quarter of the weight people lost on tirzepatide was lean mass. Eating enough protein and doing regular strength work are the two habits with the best evidence for protecting it. Sharpy turns that into one daily protein target and one 20-minute workout, then shows your progress as a Shape Score, so a smaller appetite does not cost you strength.

Talk to your prescriber about dose changes, missed doses beyond what the label says, or switching between vials and pens. Do not split, share or reuse a vial or syringe. If you want a simple daily plan for protein and strength while the vials do their part, Sharpy is free to try on the App Store.

Are Zepbound vials cheaper than pens?

Not anymore. Lilly lists the same self-pay prices for the single-dose vials and the KwikPen at every dose. The single-dose pen is the insurance option, where eligible people with commercial coverage may pay as low as $25 a month with the savings card.

How many mL is a Zepbound vial dose?

Every single-dose Zepbound vial holds 0.5 mL, whatever the strength. The strength (2.5 mg to 15 mg) is printed on the label, and the label says to draw up 0.5 mL. The FDA label also lists a multi-dose vial with four 0.6 mL doses, but LillyDirect listed only single-dose vials on October 29, 2026.

Can I get Zepbound vials at Walmart or CVS?

Lilly says Zepbound vials are exclusively available through LillyDirect. Your prescription goes to LillyDirect Pharmacy, and you can choose free home delivery or pickup. Walmart Pharmacy is one of LillyDirect's partner pharmacies. You cannot fill vials at a regular CVS counter.

Can I use insurance for Zepbound vials?

No. Lilly lists the vials as self-pay only. LillyDirect says they may be HSA or FSA eligible depending on your plan. If your insurance covers Zepbound, ask about the single-dose pen or the KwikPen instead.

How long can a Zepbound vial stay out of the fridge?

Per the FDA label, a single-dose vial can be kept unrefrigerated at up to 86°F (30°C) for a total of 21 days. After that, throw it away. Never freeze it, and keep it in the carton to protect it from light.

What syringe do I need for Zepbound vials?

The label says to use a syringe that can measure the dose, for example a 1 mL syringe, with a new syringe and needle for every injection. Your prescriber or pharmacist will tell you which needle length to use.
