Does Saxenda need to be refrigerated?
Before you open it, yes — keep Saxenda refrigerated at 36°F–46°F (2°C–8°C) until first use. Do not freeze it; a pen that has frozen should not be used even after thawing. After first use, most people can keep the pen at room temperature: Up to 30 days at room temperature (≤86°F / 30°C) after first use Track the date you first used it so you know when to discard: Discard pen 30 days after first use
What if Saxenda was left out of the fridge?
An unopened pen left at room temperature is generally still usable within the room-temperature window on the label (up to 30 days at room temperature (≤86°f / 30°c) after first use), but once that window is exceeded — or if it was exposed to heat above the labeled limit or to freezing — it should not be used. If you are unsure how long it sat out or how warm it got, call your pharmacist before injecting; do not guess. Never use a pen that has been frozen.
Traveling with Saxenda
For trips, carry Saxenda in an insulated bag with a cold pack (not directly touching the pen, to avoid freezing) and keep it in your carry-on, never a checked bag or a hot car. At your destination, refrigerate any unopened pens. Airport security allows medically necessary medication and cold packs; a pharmacy label or prescription can smooth the screening.

Common questions
Does Saxenda need to be refrigerated?
Unopened Saxenda is kept in the refrigerator (36–46°F / 2–8°C). Its label then allows a defined stretch outside it: 30 days after first use, at room temperature or refrigerated. Never freeze an injectable pen; if it freezes, do not use it.
How long can Saxenda stay out of the fridge?
30 days after first use, at room temperature or refrigerated, per the Saxenda label (pen, after first use). Limits differ by drug — Trulicity allows 14 days, the tirzepatide single-dose pens 21, a Wegovy pen 28 out of the fridge, and an Ozempic pen 56 from first use — so do not carry a figure over from a previous medication. If you are unsure how long yours sat out, ask your pharmacist before using it.
Can I travel with Saxenda?
Yes. Carry Saxenda in an insulated bag with a cold pack (not touching the pen, to avoid freezing) in your carry-on — never a checked bag or a hot car. Refrigerate unopened pens at your destination. Airport security permits medically necessary medication and cold packs; keeping the pharmacy label or prescription handy helps at screening.
Is Saxenda still good if it was left out overnight?
Often yes, if it stayed within the labeled room-temperature window and didn't get too hot or freeze — but check the number of days your product allows at room temperature and how warm it got. When in doubt, call your pharmacist rather than guessing. Never use a pen that has frozen, even once.
