Wegovy and Saxenda Storage: What the Australian Labels Actually Say
Wegovy and Saxenda come from the same manufacturer and sit at similar points in the fridge, but they are different molecules with separately approved storage rules — and one of them is a single-use device, which changes what "in use" even means.
Side by side
| Wegovy (semaglutide) | Saxenda (liraglutide) | |
|---|---|---|
| Fridge | 2–8°C, away from the cooling element | 2–8°C, away from the cooling element |
| Unrefrigerated | Up to 28 days, not above 30°C | 1 month after first use, below 30°C |
| Light | Store in the original carton | Keep the pen cap on |
| Freezing | Do not freeze; do not use if frozen | Do not freeze; do not use if frozen |
Wegovy: check it is clear and colourless
The Australian label for Wegovy carries an instruction the others do not: it should not be used if it does not appear clear and colourless. That is a rare case where a visual check means something — most GLP-1 heat damage is invisible, so where a label gives you an actual inspection criterion, it is worth using. Wegovy should also be protected from excessive heat, and always stored in its original carton to protect from light.
One structural difference matters for how you plan: the Wegovy label directs that it be discarded after use. It is a single-dose device, so the 28-day unrefrigerated allowance covers the period before you use it, not an in-use pen you carry around for weeks.
Saxenda: a month, and the cap does the work
Saxenda is the outlier in dosing — daily rather than weekly — which means the pen is in your hands far more often. Its label allows one month at room temperature below 30°C after first use, and asks that the cap be kept on when the pen is not in use, specifically to protect from light. It should also be protected from excessive heat and sunlight, and the needle removed and stored separately after each injection.
"Away from the cooling element"
Both labels say it, and it is the storage instruction people most often ignore. The back wall of a domestic fridge and the area around the cooling plate routinely drop below 0°C even when the fridge display reads 4°C. A pen pushed to the back is a pen at risk of freezing, and freezing is the one failure neither label offers any judgement about — it ends the pen.
Travel
- Hand luggage, never the hold — cargo temperatures can fall below freezing.
- Keep Wegovy in its carton and Saxenda capped; that is the light protection each label specifies.
- Declare medication and cooling at screening; both are exempt from liquid limits in Australia.
- A daily medicine like Saxenda spends far more time out of the fridge than a weekly one, so cooling that holds a set point matters more, not less.
- Count unrefrigerated time cumulatively — putting a pen back in the fridge does not restore the allowance.
Both share the same practical problem: a ceiling of 30°C that an Australian car park breaks in minutes, and no visible sign when it happens. Cooling that holds 0–8°C and shows a live temperature is what turns that from something you hope about into something you can check.
Frequently asked questions
How long can Wegovy be out of the fridge?
The Australian Product Information allows up to 28 days unrefrigerated at a temperature not above 30°C. It should be kept in its original carton to protect from light.
How long can Saxenda be kept at room temperature?
After first use, one month at room temperature below 30°C, or in a refrigerator at 2–8°C. Keep the pen cap on when it is not in use to protect it from light.
Can Wegovy or Saxenda be frozen?
No. Both labels say do not freeze and do not use product that has been frozen. Both also say to keep the pen away from the cooling element in the fridge, which is where accidental freezing usually happens.
Should Wegovy look clear?
Yes — the Australian label says Wegovy should not be used if it does not appear clear and colourless. That is an unusually explicit visual check for this class of medicine.
Do I need a cooler for Saxenda?
Saxenda is dosed daily, so the pen is out of the fridge more often than a weekly medicine. Whether you need active cooling depends on your climate and routine, but the 30°C ceiling applies at every moment, including in a car or a bag in summer.
