Source: Saxenda FDA prescribing information via DailyMed (SetID 3946d389-0926-4f77-a708-0acb8153b143), Section 16.2 How Supplied/Storage and Handling, read on 2026-07-12. Treat this as a summary: the full label and the patient instructions in your box are the authority.

Handling the pen or vial

Once you start using it: the in-use window is 30 days after first use. Write down the day you first used it — on the device itself or in your calendar — because the label says discard at the end of that window regardless of how much is left.

The carton it arrived in is the light protection, and the obvious place to write the first-use date, so keep the pen or vial inside it wherever you can. Between doses the needle comes off; a pen should never be stored with one attached.

Traveling with Saxenda

Refrigerate it until the day you start. From that first injection you get 30 days at room temperature, and the deadline is the deadline — write the start date down and discard the pen when you reach it, however much is left inside.
