Wegovy Storage: Fridge Time Limits & Private Prescription UK

Understanding how long can wegovy be out of fridge uk is essential for maintaining your medication's effectiveness and safety. Wegovy (semaglutide) pens can be stored at room temperature for up to 28 days below 30°C once removed from refrigeration, but specific handling rules apply to ensure optimal efficacy throughout your weight loss treatment [1].

How Long Can Wegovy Be Out of the Fridge?

Wegovy pens may be kept out of the fridge for a maximum of 28 days at temperatures below 30°C, according to the manufacturer's guidance approved by the MHRA [1]. This makes the medication suitable for everyday use without constant refrigeration, provided you store it correctly during this period.

Once you remove a Wegovy pen from the fridge, you must use it within those 28 days or discard it, even if doses remain. The pen should never be returned to the fridge after being stored at room temperature, as temperature fluctuations can compromise the semaglutide formulation [1]. If your pen has been out longer than 28 days or exposed to temperatures above 30°C, do not use it—contact your prescriber or our team at Cured Pharmacy on (+44) 116 4646009 for a replacement.

This 28-day window provides flexibility for patients who travel frequently or prefer not to refrigerate their medication constantly. However, if you're not planning to use your pen immediately, keeping it refrigerated between 2°C and 8°C extends its shelf life until the expiry date printed on the label [2].

Optimal Wegovy Storage Temperature Guidelines

Before first use, unopened Wegovy pens must be stored in a refrigerator at 2°C to 8°C, protected from light in the original carton [2]. This is the standard storage condition that maintains semaglutide stability from the point of manufacture through to your first injection.

Never freeze Wegovy pens. If a pen has been frozen—even accidentally—it must be discarded immediately, as freezing permanently damages the active ingredient [2]. Check your fridge temperature regularly, particularly in the back where items sometimes freeze, and store pens in the main compartment rather than the door where temperature varies with opening and closing.

After you start using a pen, you have two storage options: continue refrigerating it at 2°C to 8°C, or store it at room temperature below 30°C for up to 28 days. Many patients find room temperature storage more convenient for weekly injections, as the medication feels more comfortable when not cold [1][2].

Room Temperature Storage Best Practices

When storing Wegovy at room temperature, keep it away from direct sunlight, heat sources like radiators, and humid environments such as bathrooms. A bedroom drawer, kitchen cupboard away from the cooker, or a dedicated medication box works well. Always replace the pen cap after each use to protect the medication from light exposure, which can degrade semaglutide over time [2].

Travelling with Wegovy: UK and International Guidance

The 28-day room temperature allowance makes Wegovy practical for UK holidays and international travel. For journeys under four weeks, you can pack your pen in hand luggage at room temperature without refrigeration, provided ambient temperatures stay below 30°C [1].

When flying, always carry Wegovy in your hand luggage rather than checked baggage, as cargo holds can experience freezing temperatures that will damage your medication. Bring your prescription or a letter from your prescriber confirming your treatment—UK airports and international customs may request this documentation for injectable medications.

For longer trips or travel to hot climates where temperatures exceed 30°C, use an insulated medication travel case with cooling packs (not ice packs that could freeze the pen). These cases maintain stable temperatures for several hours and are widely available from pharmacies and online retailers. Our clinical team at Cured Pharmacy can provide a travel letter documenting your prescription if you're travelling abroad—simply request this when ordering.

What to Do If Storage Conditions Are Compromised

If you're unsure whether your Wegovy pen has been stored correctly—for example, after a power cut affecting your fridge, or if you've lost track of how many days it's been at room temperature—do not use it. Contact our pharmacy team or your prescriber for advice. Using compromised medication may result in reduced efficacy, meaning you won't achieve the expected weight loss outcomes demonstrated in clinical trials [3].

How Wegovy Works for Weight Loss

Wegovy contains semaglutide, a GLP-1 receptor agonist that mimics a natural hormone your body produces after eating [3]. This medication works through multiple mechanisms: it slows gastric emptying so you feel fuller for longer, reduces appetite signals in the brain, and improves how your body regulates blood sugar levels.

In the landmark STEP 1 trial involving 1,961 adults with obesity, participants using Wegovy achieved an average weight loss of 14.9% of their body weight over 68 weeks, compared to 2.4% with placebo [3]. These results positioned semaglutide as one of the most effective pharmacological weight loss treatments licensed in the UK by the MHRA.

Wegovy is administered as a once-weekly subcutaneous injection, starting at a low dose of 0.25mg and gradually increasing over 16 weeks to the maintenance dose of 2.4mg. This dose escalation minimises common gastrointestinal side effects like nausea and allows your body to adjust to the medication [3]. At Cured Pharmacy, Wegovy is available from £79.00, with all doses requiring a clinical assessment by a UK prescriber before dispensing.

Wegovy vs Other Weight Loss Treatments Available in the UK

Several GLP-1 receptor agonists are now licensed for weight management in the UK, each with distinct characteristics. Wegovy (semaglutide) offers once-weekly dosing with strong clinical evidence for sustained weight loss, making it a popular choice for patients seeking convenient administration [3].

Saxenda (liraglutide) is an alternative GLP-1 treatment requiring daily injections at a maximum dose of 3mg. While effective, the daily injection schedule and slightly lower average weight loss compared to semaglutide make it less convenient for some patients [4]. Saxenda may suit individuals who prefer daily dosing or have specific medical considerations that make weekly injections unsuitable.

Mounjaro (tirzepatide) is a newer dual GIP/GLP-1 receptor agonist that showed superior weight loss outcomes in head-to-head trials with semaglutide, with participants achieving up to 22.5% body weight reduction in the SURPASS-2 trial [5]. However, tirzepatide is currently licensed primarily for type 2 diabetes in the UK, though it may be prescribed off-label for weight management by specialist prescribers. All these treatments require proper storage and handling to maintain efficacy.

Your UK prescriber will assess your medical history, weight loss goals, lifestyle factors, and any contraindications to recommend the most suitable treatment. Factors like injection frequency preference, previous treatment responses, and concurrent medical conditions all influence this decision. Our clinical team at Cured Pharmacy provides personalised consultations to match you with the optimal medication, subject to prescriber approval.
