Wegovy Storage and Shipping: What to Do When Your Pen Arrives

If your Wegovy delivery arrived without an ice pack, or the box felt warm when you opened it, you haven't received a faulty batch. Novo Nordisk and the MHRA approved a change to how Wegovy is shipped, pens can now be transported safely at temperatures up to 30°C for up to 48 hours without refrigeration. The medication itself is completely unchanged.

Here's everything you actually need to know to store your pens correctly and use them safely.

Why There's No Ice Pack Anymore#

This is the question most patients have when they first open the box. The short answer: it's been officially approved, not an oversight.

Novo Nordisk worked with the MHRA to validate that semaglutide (the active ingredient in Wegovy) remains stable during transit at ambient UK temperatures. The pens are now shipped in smaller packaging without refrigerant gel, which is why your delivery might look different from previous orders — and why it could fit through your letterbox.

If you didn't receive a parcel, check your letterbox and behind your door before assuming it's lost. The smaller box is a common reason parcels go unnoticed.

How to Store Your Pens After Delivery#

Once your delivery arrives, the storage rules are straightforward:

Unused pens: Put them straight in the fridge. Wegovy should be stored between 2°C and 8°C, away from the freezer compartment. Stored correctly in the fridge, unused pens have a shelf life of up to 3 years.

In-use pens: Once you've started using a pen, it can be kept at room temperature, below 30°C, for up to 6 weeks. You don't need to refrigerate it between doses.

Never freeze your pens. Freezing damages the medication and the pen mechanism. If a pen has accidentally been frozen, do not use it, contact your prescriber or pharmacist.

A few practical tips worth knowing:

• Keep pens out of direct sunlight and away from heat sources (windowsills, radiators, car dashboards)
• If you store medication in a shared fridge at work, make sure it won't accidentally be placed near the freezer section
• The pen cap should always be on when not in use to protect from light

A Note for UK Summer Months#

During a heatwave, UK homes and cars can easily exceed 30°C, especially south-facing rooms or parked vehicles. If you're in the middle of a hot spell, keep your in-use pen somewhere cooler rather than on a bathroom shelf or in a handbag left in a warm car. A cool bag (without ice packs directly touching the pen) works well for short trips.

What If Your Box Felt Warm?#

This is completely normal now. The pen will feel like room temperature because it travelled without refrigeration. As long as the pen wasn't exposed to temperatures above 30°C or left in direct sunlight, it's safe to use.

If your delivery was significantly delayed — say, left in a hot porch over a summer weekend and you're genuinely unsure whether it exceeded 30°C, contact your pharmacist or prescriber rather than guessing.

What If Delivery Took More Than 48 Hours?#

The 48-hour figure refers to transit at ambient temperature. If your delivery took longer, the pen is still safe to use as you have up to 6 weeks from receipt to use it at room temperature. Put any unused pens in the fridge as normal. There's no need to discard medication because of a slightly delayed delivery.

When You Should Actually Be Concerned#

Most patients who worry about their Wegovy pens don't need to. But there are genuine situations where you should pause before injecting:

• The solution looks cloudy, discoloured, or contains visible particles (it should be clear and colourless to slightly yellow)
• The pen appears physically damaged — cracked, leaking, or with a bent needle cap
• The pen was frozen at any point
• The pen was exposed to temperatures above 30°C for an extended period or left in direct heat

If any of these apply, don't use the pen. Contact your prescriber, pharmacist, or call NHS 111 for advice on next steps. Damaged or compromised pens should be disposed of in a sharps bin — not in household waste.

Travelling with Wegovy Pens#

If you're flying or travelling abroad, a few things are worth knowing:

• You can carry Wegovy pens in your hand luggage — keep them in their original packaging with your prescription documentation
• A cool bag or insulated travel case is useful for longer journeys, particularly in hot climates
• Airline cabin pressure doesn't affect the medication, but avoid putting pens in checked luggage where temperatures can drop significantly
• If travelling to a country with high ambient temperatures, plan storage on arrival carefully — hotel minibars are often too cold and can freeze pens

If you're an existing Wegovy patient managing your treatment through Totiva's weight loss service, your prescriber can advise on travel-specific storage questions as part of your ongoing care.

GLP-1 Storage Compared#

It's worth noting that storage guidance varies slightly across GLP-1 medications. Mounjaro (tirzepatide) has similar refrigeration requirements to Wegovy, but always check the specific SmPC (Summary of Product Characteristics) for your medication rather than assuming the rules are identical.

In Short#

The absence of an ice pack isn't a problem — it's an approved change. Put unused pens in the fridge when they arrive, keep your in-use pen below 30°C and out of direct heat, and check the solution looks clear before each injection. That covers the vast majority of situations.
