Compounded tirzepatide storage: your label, warm deliveries and the 28-day rule
Store compounded tirzepatide the way your pharmacy’s label says: usually in the fridge at 36°F to 46°F, never frozen. The FDA recommends using a punctured vial within 28 days. Package arrived warm? Don’t use it. Call or text us, and we’ll handle the pharmacy.
- Your label sets the rules, not Zepbound’s
- Warm or frozen? Don’t use it. One call fixes it
- Day 28 is the limit once a vial is opened

Why “follow the label” isn’t a dodge
Your label is the rulebook.
Zepbound has its own rules. Eli Lilly tested how long Zepbound stays stable, so its label allows an unopened single-dose pen or vial to sit unrefrigerated at up to 86°F (30°C) for up to 21 days.
Your vial didn’t go through that testing. Compounded tirzepatide is prepared by a state-licensed pharmacy for you, with its own ingredients, concentration and process. The FDA hasn’t reviewed it, so Zepbound’s numbers don’t carry over.
The pharmacy sets the date. The beyond-use date on your label is the pharmacy’s answer to “how long is this good for?”. It already accounts for how they made it. Use the vial by that date, opened or not.
Label missing a storage line, or you can’t read it? Don’t guess. Text us a photo at (949) 818-8000 and we’ll confirm the storage rules with the pharmacy.
Stored right, every time.
Your medication travels from a named pharmacy to your door. Here’s how to keep it right once it’s there.
- Labels differ. Each pharmacy sets its own storage directions.
- Deliveries vary. Weather and timing can affect a package.
- Advice gets mixed. Rules for brand-name pens don’t apply to compounded vials.
A named pharmacy. Real people to call.
- Prescribed for you. A licensed physician reviews your history before anything is prescribed.
- One flat price. $169 tirzepatide, $139 semaglutide, at every dose.
- Shipped fast. Our partner pharmacy usually ships within 1 to 2 business days.

Opened vials
The 28-day rule, in real dates.
Every time a needle goes through the rubber top, there’s a small chance of contamination. That’s why the FDA recommends throwing out a multiple-dose vial 28 days after its first use, even if medication is left. If the beyond-use date on the label comes first, that date wins.
| First dose from the vial | Day 28 | Beyond-use date on label |
|---|---|---|
| October 1 | October 29 | October 15 |
| October 10 | November 7 | November 20 |
| October 20 | November 17 | November 30 |
Discard on whichever date comes first: in the first example, October 15; in the other two, day 28.
- Write the first-use date on the vial cap or the box the day you open it.
- Set a phone reminder for day 27, so you can plan your next vial.
- Running low before day 28? Tell us early and we’ll time your refill.
Warm deliveries
If something’s off, here’s exactly what to do.
Deliveries are the riskiest part of a cold chain. Weather, a late truck or a box left on the porch can warm a vial. The FDA recommends not using an injectable GLP-1 that arrives warm or without enough cold packs. Here’s the short version for every situation we hear about.
| What happened | What to do |
|---|---|
| Arrived warm, or the cold packs are fully melted | Don’t use it. Keep the vial and box. Call or text us. |
| The vial froze, or has ice crystals | Don’t use it, even after it thaws. Call or text us. |
| Left out of the fridge overnight | Don’t use it unless your label allows it. Call or text us to check. |
| Cloudy, has particles, or the seal is broken | Don’t use it. Call or text us. |
| The label doesn’t match your prescription | Don’t use it. Call or text us right away. |
| Past day 28, or past the beyond-use date | Discard it safely. Tell us if you need a refill sooner. |
You call us. We handle the pharmacy.

At home
Set up your fridge once.
Middle shelf, not the door
The door swings warmer every time it opens. A middle shelf holds the steadiest temperature.
Away from the back wall
Many fridges run coldest at the back, where vials can freeze. Keep a few inches of space.
In its box, out of light
Keep the vial in its original box unless your label says otherwise. It protects from light and bumps.
A simple fridge thermometer
It tells you the fridge really sits between 36°F and 46°F, not just what the dial says.
Tirzepatide storage: your questions, answered
How should I store compounded tirzepatide?
Exactly as the label from your pharmacy says. Most say to keep the vial in the refrigerator at 36°F to 46°F (2°C to 8°C) and never freeze it. The label wins over anything you read online, including Zepbound’s rules, because how long a compounded vial stays good depends on how that pharmacy made it.
Does compounded tirzepatide need to be refrigerated?
Almost always, yes. The FDA says injectable GLP-1 drugs need refrigeration as their labels indicate. Check the storage line on your vial’s label; if it’s missing or unclear, call or text us and we’ll get the answer from the pharmacy for you.
How long does compounded tirzepatide last in the fridge?
Unopened, until the beyond-use date your pharmacy printed on the label. Once you puncture the vial, the FDA recommends using it within 28 days, even if medication is left, or by the beyond-use date if that comes first.
My tirzepatide arrived warm. Can I use it?
No. The FDA recommends not using an injectable GLP-1 that arrives warm or with too few cold packs. Keep the vial and the box, and call or text us at (949) 818-8000 24/7. We follow up with the pharmacy and get back to you with what happens next.
Does Zepbound’s 21-day room-temperature rule apply to compounded vials?
No. Zepbound’s label lets an unopened single-dose pen or vial sit unrefrigerated at up to 86°F for up to 21 days. That rule was tested for Zepbound, not for a vial a compounding pharmacy prepared. Follow your own label.
What if my vial froze?
Don’t use it, even after it thaws. Freezing can damage the medication. Call or text us at (949) 818-8000 and we’ll sort it out with the pharmacy.
Important safety information
Compounded tirzepatide and semaglutide are not FDA-approved, and the FDA hasn’t reviewed them for safety, effectiveness or quality. Both medicines may cause thyroid tumors, including cancer: don’t use either if you or a family member has had medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN 2).
Read the full safety information
In studies with rodents, both medicines caused thyroid tumors; it isn’t known whether they cause them in people. Tell your provider if you notice a lump or swelling in your neck, hoarseness, trouble swallowing or shortness of breath.
Serious side effects can include inflammation of the pancreas (pancreatitis), gallbladder problems, low blood sugar (especially with insulin or sulfonylureas), kidney problems from dehydration, severe stomach problems, serious allergic reactions, vision changes in people with type 2 diabetes, and depression or thoughts of suicide. Tell your care team before any surgery or procedure that uses anesthesia or deep sedation. Don’t combine either medicine with other GLP-1 medicines.
Tirzepatide can make birth control pills less effective: use another method for 4 weeks after you start and after each dose increase. Semaglutide should be stopped at least 2 months before a planned pregnancy. Tell your provider if you’re pregnant, planning to be, or breastfeeding.
This is a summary, not the complete safety information. Read the full Prescribing Information for FDA-approved tirzepatide (Zepbound) and semaglutide (Wegovy), and talk with your provider. You can report side effects to the FDA at 1-800-FDA-1088 or fda.gov/medwatch.
