Injectable GLP-1s are cold-chain products. Here is what that means for your fridge, your deliveries and your holidays.
Every major injectable GLP-1 requires refrigerated storage and transport between 2°C and 8°C — that is 36°F to 46°F. This applies to semaglutide products including Ozempic and Wegovy, and to tirzepatide products including Mounjaro and Zepbound.
That single fact drives a lot of practical consequences that nobody mentions when you sign up: what happens when a delivery sits on a doorstep in July, whether you can take a pen on holiday, why your medication arrived in a box of dry ice, and what the 28-day room temperature allowance actually permits.
Oral GLP-1s sidestep all of it. Foundayo tablets and Wegovy tablets need no refrigeration at all, which is a genuine and underrated advantage if you travel, live somewhere hot, or simply do not want to organise your fridge around a prescription.
Store unopened injectable GLP-1 pens and vials in a refrigerator at 2-8°C (36-46°F). Do not freeze. Once in use, most products can be kept at room temperature below 30°C (86°F) for up to 28 days. After that window, discard it — even if medication remains. Always follow the specific storage instructions on your product label, which override any general guidance.
| Medication | Refrigeration required? | Room temperature allowance | Notes |
|---|---|---|---|
| Semaglutide injection (Wegovy, Ozempic) | Yes, 2-8°C until first use | Up to 28 days below 30°C once in use | Do not freeze. Discard after the in-use period |
| Tirzepatide injection (Zepbound, Mounjaro) | Yes, 2-8°C until first use | Limited period per label once opened | Unopened vials must remain refrigerated |
| Compounded injectable GLP-1s | Yes, same cold chain | Varies by compounder — check your label | Compounded formulations may have different stability |
| Wegovy tablets (oral semaglutide) | No | Standard room temperature storage | Take on an empty stomach with a sip of water |
| Foundayo (orforglipron) | No | Standard room temperature storage | No food or water restrictions; any time of day |
This table summarizes general guidance. Your product label is authoritative and may differ. When in doubt, ask the dispensing pharmacist.
Cold-chain compliance means the medication must stay within its labelled temperature range for the entire journey, not just at the start and end. Specialty pharmacies use validated insulated shippers with pre-conditioned coolant, sized for the expected transit time and season.
This is why deliveries typically go out early in the week — a package shipped Thursday risks sitting in a depot over a weekend. It is also why some pharmacies ship overnight only, and why you may be asked to confirm someone will be home.
Manufacturer-direct channels have an advantage here. NovoCare Pharmacy and LillyDirect ship their own products, and Amazon One Medical uses Amazon's own logistics network. Compounded platforms rely on partner pharmacies whose cold-chain validation you generally cannot inspect.
If a shipment is delayed and you are worried, the right move is to contact the pharmacy before using the medication rather than after. A pharmacist can tell you whether the packaging was rated for the elapsed time.
This is the situation people most often ask about and most often handle badly. The instinct is to use it anyway. Do not.
Travel is manageable, but it needs a small amount of planning. Carry the medication in your hand luggage rather than checked baggage — hold temperatures are not controlled and a lost bag means a lost prescription.
Keep it in the original labelled carton, and carry your prescription or a letter from your prescriber. This makes security screening straightforward and matters if you need a replacement abroad.
Use a proper insulated medical travel case with a cooling element rather than a lunch bag with ice. The goal is staying within 2-8°C, and direct contact with ice can freeze the product, which is as damaging as overheating.
For a trip within the 28-day in-use window, an already-started pen kept below 30°C is generally fine without refrigeration — check your label. That makes short trips considerably simpler than they first appear.
If you are travelling somewhere hot for an extended period, this is the situation where an oral GLP-1 genuinely shines. Foundayo and Wegovy tablets need no refrigeration and no special packaging at all.
Most telehealth platforms ship monthly, aligned to a monthly plan or a refill cycle. Providers with multi-month plans often still ship monthly rather than sending three months at once, because storing that much refrigerated medication at home is impractical for many households.
A few models remove the shipping question entirely. Walgreens Virtual Healthcare offers same-day in-store pickup at thousands of retail pharmacies, and LillyDirect added Walmart Pharmacy retail pickup in October 2025. If you have had a delivery go wrong, or you live somewhere with unreliable doorstep delivery, pickup is worth prioritising.
Curex states orders ship in one to two business days. NovoCare Pharmacy provides free home delivery on all Wegovy dose strengths. Amazon One Medical uses Amazon's own delivery network with cold-chain handling for injectables.
When comparing providers, ask two questions: how often do you ship, and what happens if a shipment arrives outside temperature range. The second answer tells you more about a company than most of its marketing.
Yes. Injectable semaglutide products including Wegovy and Ozempic must be stored refrigerated at 2-8°C (36-46°F) until first use. Once in use, they can generally be kept at room temperature below 30°C (86°F) for up to 28 days, after which they should be discarded. Oral semaglutide tablets do not require refrigeration.
Once in use, most injectable GLP-1s can be kept at room temperature below 30°C (86°F) for up to 28 days. After that window the product should be discarded even if medication remains. Unopened pens and vials should stay refrigerated. Always follow your specific product label.
Do not use it. Photograph the package and coolant, then contact the dispensing pharmacy the same day — they know the packaging specification and transit time and can advise whether it is still usable. Reputable pharmacies replace temperature-excursion shipments; this is a normal part of cold-chain dispensing. A temperature excursion can affect potency and you cannot tell by looking.
No, never. A frozen GLP-1 must be discarded even after thawing and even if it looks normal. Store it in the main body of the fridge away from the back wall and freezer compartment, where accidental freezing is most likely.
Yes, with planning. Carry it in hand luggage rather than checked baggage, keep it in the original labelled carton with your prescription, and use a proper insulated medical travel case with a cooling element — not ice in direct contact, which can freeze the product. For trips within the 28-day in-use window, an already-started pen kept below 30°C is generally fine.
Between 2°C and 8°C, which is 36°F to 46°F — standard refrigerator temperature. This applies to unopened injectable semaglutide and tirzepatide products. Many domestic fridges run outside this range without the owner knowing, so a cheap fridge thermometer is a worthwhile purchase.
No. Foundayo (orforglipron) tablets and Wegovy tablets are stored at standard room temperature with no cold chain, no special packaging and no travel complications. This is a genuine practical advantage if you travel frequently or live somewhere hot.
Most ship monthly, aligned to a refill cycle, even on multi-month plans — storing several months of refrigerated medication at home is impractical for most households. Curex states orders ship in one to two business days. Walgreens and LillyDirect via Walmart both offer retail pickup, which removes shipping risk entirely.
