Wegovy is semaglutide, given as a weekly injection and licensed for weight management. Like other injectable medicines, it comes with specific storage instructions, and getting those details from an official source matters more than relying on general assumptions about how injectable medicines are usually kept, or on what you may have read about a different product.

This page will not state a specific temperature range or storage duration for you to rely on. Those figures can depend on the exact product, packaging, and whether a pen is in use or unopened, and they are set out precisely in the patient information leaflet that comes with your Wegovy and confirmed by your pharmacy. Always check your own leaflet rather than a number you have seen elsewhere, including on this page, a general health website, or a conversation with someone using a different pack size or product.

What to check

  • The patient information leaflet that came with your specific pack, which sets out storage conditions before and after first use
  • Your pharmacist, if anything in the leaflet is unclear or you are unsure how it applies to your situation, particularly around travel or interrupted refrigeration
  • The expiry date printed on your pack, alongside the storage instructions, which may differ from the general shelf life once a pen is in use

A checklist worth recording

  • Where you keep your current pen or pack, and whether that matches the leaflet's instructions
  • The date you started using a pen that was previously stored differently, such as one you have taken out of a fridge for ongoing use
  • Any questions you asked your pharmacist about storage, and what they told you, so you do not need to ask again next time
  • Any occasion where storage conditions may have been interrupted, such as a fridge outage, a hot car, or a delayed delivery
  • The date you collected each pack, alongside its printed expiry date, so the two are easy to check against each other

Travel and everyday disruptions

If you are travelling, or if you are ever unsure whether your Wegovy has been kept within the conditions described in its leaflet — for example, after a long delay in transit, extreme heat, or a broken fridge — do not guess whether it is still fine to use. Contact your pharmacist for advice specific to what happened, and keep a note of what occurred and when, in case it is useful for that conversation or for a replacement prescription. A short note made at the time, while details are fresh, is far more useful than trying to reconstruct what happened a week later.

If you are planning travel in advance, it is worth checking the leaflet's guidance on transport before you go, rather than after you have already packed, so you have time to ask your pharmacist any questions and arrange suitable insulated storage if that is what the instructions call for.

The safest approach to Wegovy storage is not memorising a number. It is knowing exactly where to check the real one, checking it before you need to, and keeping a short record of what you confirmed and when, so that if a question ever comes up, you already have the answer written down rather than needing to work it out under pressure.

Keeping the leaflet accessible

It is worth keeping a photo of the storage section of your leaflet, or the leaflet itself, somewhere you can find it quickly — a phone photos folder, a document scan, or a physical folder at home. Instructions read carefully once at the pharmacy counter are easy to half-remember weeks later, especially if you are managing several medicines or a change in routine at the same time. Having the actual text to hand removes the guesswork entirely.

This is a small piece of preparation that pays off precisely when you need it least expected: a fridge failure, an unplanned trip, or simply a moment of doubt about whether a pen kept in a bag for a few hours is still fine to use. Confirming with the leaflet and your pharmacist, rather than assuming, is the safer habit either way.
