Does Wegovy Have to Be Stored in the Fridge?

Step 1: Keep your unused pens in the fridge door, but away from the freezer

When you receive your Wegovy pens from the pharmacy, the first job is straightforward: put them in the fridge at 2–8°C. The door shelf works well because it is easy to reach, but keep the pens away from the ice-maker or freezer drawer. Freezing damages the medicine, a pen that has been frozen should not be used, even if it looks normal once thawed.

One common misconception worth setting aside: some people assume the medicine must stay absolutely cold at all times and feel anxious if the fridge temperature fluctuates slightly. In practice, brief variation within a properly functioning household fridge is unlikely to be a problem. What matters is avoiding extremes, freezing at the lower end, and direct heat or sunlight at the upper end.

If you are unsure whether your pen has been stored correctly at any point, read our guide on whether Wegovy has to be kept in the fridge before injecting, or call your dispensing pharmacy. The Wegovy overview on the nume website covers what to expect from treatment more broadly, and our team is available seven days a week if a storage question comes up between doses.

Step 2: Understand the room-temperature window before you travel

You do not need to keep Wegovy in a cool bag every time you leave the house. The medicine's SmPC (Summary of Product Characteristics) allows a limited period at room temperature, the Patient Information Leaflet that ships with your pen states the maximum duration and the temperature ceiling. We deliberately do not print that figure here, because it applies to specific conditions and quoting a number out of context can lead to unsafe assumptions. Read the leaflet, or ask your prescriber.

For holidays and longer trips, a small insulated travel pouch keeps the pen within its range without the faff of sourcing ice. If you are travelling by air, carry your pen in hand luggage rather than the hold, aircraft hold temperatures can drop well below freezing. The broader question of semaglutide refrigeration covers the same principles for the active ingredient across formulations.

Frequent travellers sometimes ask whether the cost of treatment can be offset by splitting storage across trips, the answer is: never use a pen past its room-temperature window to avoid waste. Discard it and contact your pharmacy.

Step 3: Check the pen before every injection

Before each weekly dose, inspect the pen. The liquid inside should be clear or very faintly yellow and free of particles. Cloudy, discoloured or particulate solution should not be injected, contact your pharmacy straightaway. This step takes about ten seconds and is worth making a habit of.

After removing the pen from the fridge, some people prefer to let it sit at room temperature for a short while before injecting, this is a personal comfort choice (cold liquid can sting slightly at the injection site) and is within the room-temperature allowance, provided you inject it well within that window. The guidance on injection sites goes into technique in more detail, including rotating locations between the abdomen, thigh and upper arm.

Needles should be changed with each injection and disposed of safely. A sharps container makes home disposal straightforward and compliant with household waste regulations.

What changes if you switch to the Wegovy tablet?

In June 2026 the MHRA approved the first oral GLP-1 medicine licensed in the UK for weight management: the Wegovy tablet (semaglutide 25mg maintenance dose, starting at 1.5mg). One practical difference from the injection is that the tablet requires no refrigeration, it can be stored at room temperature, making it considerably easier to manage on the move. The MHRA's announcement on semaglutide approvals covers the evolving range of licensed formats if you want the regulatory detail.

Whether the injection or the tablet is more suitable for you depends on your clinical picture, something a prescriber works through during a consultation, not a decision to make based on convenience alone. The NHS page on semaglutide sets out the medicine's profile clearly for both formats. There is a fuller discussion of the injection's practical side on the page covering off-fridge storage in more detail.

If you are considering starting Wegovy or transferring from another provider, check your eligibility with our prescribers, the consultation is free, clinical review happens the same day, and your questions about storage, dosing and what to expect are answered before your first pen is dispatched.
