How Long Does A Wegovy Pen Last? Get Yours Tomorrow

Published on: June 03, 2026

Understanding how long does a wegovy pen last uk is essential for planning your weight loss treatment. Each Wegovy pen contains four weekly doses, lasting exactly one month when used as prescribed. At Cured Pharmacy, we supply genuine UK-licensed Wegovy pens from £79.00 with next-day delivery and free clinical assessment by our registered prescribers.

How Long Does A Wegovy Pen Last UK: The Complete Answer

Each Wegovy FlexTouch pre-filled pen contains four single-dose injections, designed for once-weekly administration. This means one pen lasts exactly 28 days when following the prescribed treatment schedule [1]. The pen is engineered with precise dose counters to ensure accurate delivery across all four weekly injections.

Your Wegovy treatment follows a gradual dose escalation schedule over 16 weeks, starting at 0.25mg and increasing to the maintenance dose of 2.4mg weekly. During the initial titration phases, you may use lower-dose pens that still provide four weekly injections, but the concentration differs based on your current treatment stage [1]. Our UK prescribers at Cured Pharmacy determine your appropriate starting dose during your free consultation.

Once opened and first used, the Wegovy pen remains stable for 6 weeks when stored correctly in the refrigerator between 2°C and 8°C. However, since each pen contains only four doses for four weeks of treatment, you'll typically finish the pen before this 6-week window expires [2].

Wegovy Pen Storage and Shelf Life Guidelines

Proper storage is critical for maintaining Wegovy's effectiveness throughout its lifespan. Unopened Wegovy pens must be refrigerated at 2°C to 8°C and remain viable until the expiry date printed on the label. Never freeze Wegovy pens, and if accidentally frozen, they must be discarded immediately [2].

Once you've administered your first injection, the pen can be stored in the refrigerator or at room temperature (not exceeding 30°C) for up to 6 weeks. Keep the pen cap on when not in use to protect from light. Many patients find room temperature storage more comfortable for injections, as cold medication can cause temporary injection site discomfort.

When travelling with Wegovy, you can keep the pen at room temperature for up to 6 weeks, making short trips manageable without refrigeration. For longer journeys, consider using insulated medication travel cases with ice packs. Always carry your prescription documentation when travelling with injectable medications, particularly for international trips.

What Happens If Storage Guidelines Aren't Followed

Semaglutide, the active ingredient in Wegovy, degrades when exposed to extreme temperatures or direct sunlight, potentially reducing its clinical effectiveness. If your Wegovy pen has been frozen, exposed to temperatures above 30°C for extended periods, or left in direct sunlight, do not use it. Contact our pharmacy team on (+44) 116 4646009 for guidance on obtaining a replacement through your prescriber.

Wegovy Injection Frequency and Dosing Schedule

Wegovy is administered once weekly on the same day each week, at any time of day, with or without meals. Most patients establish a routine injection day (such as every Sunday evening) to maintain consistency. If you miss a dose and it's been less than 5 days since your scheduled injection, administer it as soon as you remember. If more than 5 days have passed, skip that dose and resume your regular schedule [1].

The dose escalation protocol for Wegovy spans 16 weeks, gradually increasing your tolerance and minimising gastrointestinal side effects. The standard titration schedule begins at 0.25mg weekly for 4 weeks, then 0.5mg for 4 weeks, 1mg for 4 weeks, 1.7mg for 4 weeks, and finally the maintenance dose of 2.4mg weekly [1]. This gradual approach significantly reduces nausea and vomiting compared to starting at higher doses.

Each dose level requires a specific pen strength, meaning you'll transition through different pen types during your first 16 weeks. After reaching the 2.4mg maintenance dose, you'll continue with the 2.4mg pens indefinitely, with each pen providing your monthly supply of four weekly injections.

Adjusting Your Injection Schedule

If you need to change your regular injection day, ensure at least 3 days (72 hours) pass between doses. For example, if you normally inject on Monday but need to switch to Thursday, you can make this change as long as it's been at least 3 days since your last injection. Your new day then becomes your permanent weekly schedule. Consult with your prescriber before making schedule changes to ensure safe administration.

Treatment Active Ingredient Injection Frequency Pen Duration Starting Price
Wegovy Semaglutide Once weekly 4 weeks (4 doses) From £69.00
Mounjaro Tirzepatide Once weekly 4 weeks (4 doses) From £124.99
Saxenda Liraglutide Daily 30 days (30 doses) From £68.00

How Wegovy Compares to Other Weight Loss Injections

Wegovy contains semaglutide, a GLP-1 receptor agonist that achieved average weight reductions of 14.9% over 68 weeks in the landmark STEP 1 trial, compared to 2.4% with placebo [3]. This once-weekly injection works by mimicking the natural hormone GLP-1, which regulates appetite, slows gastric emptying, and improves blood sugar control.

Alternative injectable treatments include Saxenda, which requires daily injections rather than weekly administration. Mounjaro represents a newer dual GIP/GLP-1 receptor agonist showing enhanced weight loss outcomes in clinical trials, though with different mechanisms and cost considerations. Your UK prescriber will assess which treatment aligns with your medical history, lifestyle preferences, and weight loss goals.

All injectable weight loss medications available through Cured Pharmacy require prescription approval following clinical assessment. Our registered prescribers evaluate your BMI, medical conditions, current medications, and previous weight loss attempts to determine the most appropriate treatment. The consultation process takes under 3 minutes online, with prescriptions issued the same day for eligible patients.

Getting Your Wegovy Prescription Online UK

Wegovy is a prescription-only medication in the UK, requiring assessment by a registered prescriber before dispensing. At Cured Pharmacy, our clinical team includes GPhC-registered prescribers who conduct thorough online consultations to ensure Wegovy is safe and appropriate for your individual circumstances [4].

The consultation process involves completing a detailed medical questionnaire covering your weight history, current health conditions, medications, and previous weight loss attempts. Our prescribers review your responses and may request additional information or suggest alternative treatments if Wegovy isn't suitable. Approved prescriptions are processed immediately, with your medication dispatched for next-day delivery in discreet packaging.

Wegovy is licensed for adults with a BMI of 30 kg/m² or greater, or 27 kg/m² or greater with at least one weight-related comorbidity such as type 2 diabetes, hypertension, or obstructive sleep apnoea [4]. NICE guidelines recommend GLP-1 receptor agonists as part of a comprehensive weight management programme including dietary modification and increased physical activity.

Ongoing Prescriber Support

Weight loss treatment requires regular monitoring and prescription renewals. Our prescribers conduct follow-up assessments every 3 months to evaluate your progress, manage any side effects, and adjust treatment as needed. You can contact our clinical team at any time during your treatment journey with questions or concerns about your Wegovy therapy.

Wegovy Side Effects and What to Expect

The most common side effects of Wegovy involve the gastrointestinal system, affecting more than 10% of patients in clinical trials. These include nausea, diarrhoea, vomiting, constipation, and abdominal pain, typically occurring during dose escalation phases and diminishing as your body adjusts to the medication [3]. The gradual titration schedule significantly reduces the severity of these effects.

Most gastrointestinal symptoms are mild to moderate and resolve within several weeks. Eating smaller, more frequent meals, avoiding high-fat foods, and staying well-hydrated can help manage these effects. If nausea becomes severe or persistent, your prescriber may slow the dose escalation or recommend anti-nausea strategies.

Serious side effects are rare but require immediate medical attention. These include severe abdominal pain that doesn't resolve (potential pancreatitis), vision changes, signs of thyroid tumours (lump in neck, hoarseness, difficulty swallowing), or symptoms of gallbladder problems [2]. Contact your GP or NHS 111 immediately if you experience any severe or concerning symptoms. Our pharmacy team at Cured Pharmacy is available on (+44) 116 4646009 for non-emergency medication queries.
