The rules in brief
Refrigerate at roughly 36–46°F (2–8°C). Never freeze — frozen medication is discarded, even after thawing. Keep it in its carton to protect from light. Check your specific product labeling for how long it can sit at room temperature, because the allowance differs between products and between unused and in-use pens.
Always follow the instructions supplied with your medication over any general guidance, including this page.
Why This Matters More Than With Ordinary Prescriptions
Semaglutide and tirzepatide are peptides — larger, more fragile molecules than a typical small-molecule tablet. Heat can degrade them, and freezing can damage them irreversibly. Degraded medication does not necessarily look different, which is the problem.
And unlike a prescription you collect from a counter, most GLP-1s now arrive by courier. That introduces a cold chain: the medication travels in an insulated box with cold packs and has to stay in range the whole way. Most of the time it works. When it doesn't, you are the one who notices.
Storage by Product Type
| Product | Storage | Key point |
|---|---|---|
| Unused injection pens (Wegovy, Ozempic, Zepbound, Mounjaro) | Refrigerate 36–46°F in the original carton | Manufacturer labeling permits a limited room-temperature period — check your leaflet |
| In-use injection pens | Refrigerated or at room temperature per the product labeling | The in-use allowance differs from the unused one; discard after the stated period |
| Single-dose vials (e.g. Zepbound vials) | Refrigerate until use | Discard after the stated in-use window; do not save partial doses |
| Compounded injections | Follow the compounding pharmacy's instructions exactly | Beyond-use dates are typically shorter than brand-name expiry dates |
| Oral tablets (Wegovy pill, Foundayo) | Room temperature per labeling | No cold chain — one practical advantage of oral GLP-1s |
Compounded medication has its own dates
Compounded products carry a beyond-use date set by the compounding pharmacy, not a manufacturer expiry date. These are often considerably shorter — sometimes weeks rather than months — and they assume specific storage conditions.
If you buy a multi-month supply from a provider like Brello or Henry Meds, ask what the beyond-use date is on what you receive, and make sure it covers the period you have paid for.
Practical fridge advice
- Store it on a middle shelf, not in the door — door temperatures swing every time it opens.
- Keep it away from the back wall and the freezer compartment, where things freeze accidentally.
- A cheap fridge thermometer is a worthwhile purchase. Domestic fridges are often colder or warmer than their dial suggests.
- Leave it in the original carton. Light exposure matters, and the carton has the expiry date and lot number on it.
When a Shipment Arrives Warm
This happens — a delayed courier, a box left in the sun, a hot week. Handle it in this order.
- Photograph everything before you unpack further: the box, the cold packs (frozen, slushy, or fully liquid), any temperature indicator strip, and the medication itself.
- Note the delivery time and how long the tracking says it was in transit.
- Put it in the fridge while you sort it out. Do not inject it and do not throw it away yet.
- Contact the pharmacy or provider immediately and describe what you found. Same day, not next week.
- Ask specifically whether the product remained within its acceptable temperature range, and get the answer in writing.
Do not make this judgment yourself. The manufacturer's room-temperature allowance is product-specific, and the pharmacy has the information needed to decide. Most reputable providers will replace a shipment that failed the cold chain — but nearly all of them require prompt reporting, which is exactly why photographing it at the door matters.
Reduce the odds in advance
- Have deliveries sent somewhere they will be brought inside quickly — a workplace beats a doorstep in July.
- Time refills so they do not arrive while you are away.
- Turn on delivery notifications so you can bring the box in immediately.
- Ask your provider what its cold-chain packaging and replacement policy actually is before your first order.
How Often Providers Ship
Shipping cadence affects both cost and cold-chain risk — more shipments means more chances for one to go wrong, while larger shipments mean more medication at stake if one does.
- Monthly is the default at most telehealth providers, including Mochi, Alloy, and Ivím.
- Quarterly at prepaid providers like Brello, which renews every 11 weeks.
- Multi-month bundles at Henry Meds, where some plans ship on roughly two-month cycles.
- Pharmacy-set at insurance-billed providers — Form Health, PlushCare, Calibrate, and WeightWatchers all route to your own pharmacy.
- Local pickup at CVS, Walgreens, and Walmart (for Zepbound via LillyDirect), which removes the shipping risk entirely.
If summer heat or unreliable delivery is a real concern where you live, a retail pickup option is worth more than a small price difference.
Traveling With GLP-1s
- Hand luggage only. Cargo holds are not temperature-controlled, and checked bags get lost.
- TSA allows medically necessary liquids and injectables above the usual limits — declare them at screening.
- Carry the pharmacy label or a copy of your prescription. It removes friction at security and at international borders.
- Use an insulated medication case with a cold pack. Choose one designed for medication rather than a freezer block that could freeze the pen.
- Hotel minibar fridges are often too cold or not cold enough. Ask for a proper fridge, and check it with a thermometer if you are staying a while.
- For long trips, ask your provider about timing a refill around your travel rather than carrying several months at once.
Needle and Sharps Disposal
Used needles and pens are regulated waste in most places, and this is one detail telehealth providers rarely explain well.
- Use an FDA-cleared sharps container if your provider supplies one. Several include supplies in the plan price — Henry Meds, for example, states supplies are included.
- If you do not have one, a heavy-duty plastic container with a tight, puncture-resistant lid is the commonly recommended substitute. Not a soft bottle, and never a glass jar.
- Never place loose needles in household rubbish or recycling.
- Disposal rules vary by state. Many pharmacies, hospitals, and local health departments run take-back programs — your state health department website is the reliable source.
Frequently Asked Questions
What temperature should GLP-1 medication be stored at?
Refrigerated, typically between 36°F and 46°F (2°C to 8°C), and not frozen. Manufacturer labeling for products like Wegovy and Zepbound allows a limited period at room temperature — check the specific instructions that came with your medication, because the allowance differs by product and by whether the pen has been used. Never use medication that has been frozen, even if it has thawed.
My GLP-1 arrived warm. Can I still use it?
Do not decide that yourself. Photograph the package, the cold pack, and any temperature indicator, then contact the pharmacy or provider immediately and describe how long it was in transit and how warm it felt. They can tell you whether it remains within the acceptable range for that product. Reputable providers replace shipments that failed the cold chain — but they generally require you to report it promptly, so do not wait.
Can I travel with GLP-1 medication?
Yes. Carry it in your hand luggage rather than checked baggage, since cargo holds are not temperature-controlled and bags get lost. TSA permits medically necessary liquids and injectables through security; declare them at screening. Bring the prescription label or a copy of your prescription. Use an insulated travel case with a cold pack, and avoid anything that could freeze the medication.
How should I dispose of used needles?
In an FDA-cleared sharps container, or failing that a heavy-duty plastic container with a tight-fitting, puncture-resistant lid. Never put loose needles in household rubbish or recycling. Disposal rules vary by state — many pharmacies, hospitals, and health departments run take-back programs. Ask your provider what they supply and what your state requires.
