Wegovy Dose Calculator UK: Complete Pricing Guide

Published on: June 03, 2026

Understanding the wegovy dose calculator uk is essential for planning your weight loss journey and budgeting accurately. At Cured Pharmacy, we provide transparent upfront pricing from £79.00 per pen, with a UK-registered clinical team guiding you through each dose escalation step. Every prescription requires a clinical assessment by a UK prescriber to ensure safe, personalised treatment.

How Wegovy Dosing Works: The Complete Titration Schedule

Wegovy follows a structured dose escalation protocol designed to minimise gastrointestinal side effects whilst optimising weight loss outcomes [1]. The titration begins at 0.25 mg once weekly and gradually increases over 16 weeks to the maintenance dose of 2.4 mg weekly.

This gradual approach allows your body to adapt to semaglutide's effects on gastric emptying and appetite regulation. Clinical trials demonstrated that patients following the full titration schedule experienced fewer treatment discontinuations due to side effects compared to rapid dose escalation [1][2].

The standard Wegovy dosing schedule approved by the MHRA progresses as follows: 0.25 mg for 4 weeks, 0.5 mg for 4 weeks, 1.0 mg for 4 weeks, 1.7 mg for 4 weeks, then 2.4 mg as the ongoing maintenance dose [3]. Each pen delivers four weekly doses at the prescribed strength, meaning you'll need a new pen monthly throughout your treatment.

Why Dose Escalation Matters

The titration protocol isn't arbitrary—it's based on extensive pharmacokinetic data from the STEP clinical trial programme [2]. Patients who skip doses or accelerate the schedule experience significantly higher rates of nausea, vomiting, and diarrhoea, often leading to treatment abandonment before reaching therapeutic benefit.

Your UK prescriber may adjust the schedule if you experience persistent side effects, occasionally extending a dose level for an additional month before progression. This personalised approach, available through our clinical consultation, ensures you achieve optimal outcomes whilst maintaining tolerability.

Calculating Your Wegovy Cost Across the Dose Calculator UK Schedule

Transparent pricing is fundamental to treatment planning. At Cured Pharmacy, Wegovy starts from £79.00 per pen, with each pen containing four weekly doses at your prescribed strength. This means your monthly cost remains consistent as you progress through the titration schedule.

During the initial 16-week titration period, you'll use five pens total (one per month for months 1-4, then continuing monthly at maintenance). Once you reach the 2.4 mg maintenance dose, you'll continue with one pen monthly for as long as your prescriber recommends continued treatment—typically 12-24 months based on your weight loss response [1][3].

Unlike some providers who advertise low entry prices but add hidden consultation fees or delivery charges, our pricing includes your UK prescriber assessment, prescription issuance, and discreet Royal Mail delivery. There are no surprise costs when you calculate your total treatment investment.

Wegovy Dosing Schedule UK: Month-by-Month Breakdown

Month 1 begins with the 0.25 mg starter dose, where you'll inject once weekly on the same day each week. This lowest dose initiates GLP-1 receptor activation without overwhelming your system. Many patients report mild appetite reduction even at this introductory level, though significant weight loss typically begins later in the schedule [2].

Months 2-4 progress through 0.5 mg, 1.0 mg, and 1.7 mg respectively. The 1.0 mg dose often represents the point where patients notice substantial appetite suppression and changes in food preferences—particularly reduced cravings for high-fat, energy-dense foods. This aligns with semaglutide's action on hypothalamic appetite centres and reward pathways [1][4].

Month 5 onwards maintains the 2.4 mg therapeutic dose, which delivered an average 14.9% body weight reduction over 68 weeks in the STEP 1 trial [2]. Your prescriber will monitor your progress through follow-up consultations, adjusting treatment duration based on your individual response and weight loss goals.

What If You Miss a Dose?

If you miss your weekly Wegovy injection and it's been less than 2 days, take it as soon as you remember. If more than 2 days have passed, skip that dose and resume your regular schedule [3]. Missing multiple doses may require restarting at a lower dose level to avoid side effects—your UK prescriber will provide specific guidance based on how long you've been off treatment.

Set a weekly phone reminder for injection day to maintain consistency. Stable weekly dosing optimises semaglutide's pharmacodynamic effects and produces more predictable weight loss compared to irregular administration patterns.

Clinical Efficacy: What the Wegovy Dose Calculator Delivers

The STEP clinical trial programme enrolled over 4,500 adults with obesity or overweight plus weight-related comorbidities, demonstrating that Wegovy 2.4 mg produces superior weight loss compared to lifestyle intervention alone [2]. In STEP 1, participants achieved mean weight reduction of 14.9% versus 2.4% with placebo over 68 weeks.

Importantly, weight loss correlates with dose level. The 2.4 mg maintenance dose significantly outperformed lower semaglutide doses tested in earlier trials, which is why the full titration to this target is essential for optimal outcomes [1][2]. Patients who discontinue at 1.0 mg or 1.7 mg typically achieve only 60-75% of the weight loss seen at the full maintenance dose.

Beyond the scales, Wegovy treatment in clinical trials improved cardiovascular risk markers including blood pressure, lipid profiles, and glycaemic control in patients with prediabetes [4]. These metabolic benefits often emerge before substantial weight loss occurs, reflecting semaglutide's direct effects on multiple organ systems.

Who Can Use the Wegovy Dose Calculator UK?

Wegovy is licensed in the UK for adults with a BMI of 30 kg/m² or above, or 27 kg/m² with at least one weight-related comorbidity such as type 2 diabetes, hypertension, or obstructive sleep apnoea [3]. Your UK prescriber will calculate your BMI and review your medical history during the online consultation to confirm eligibility.

Certain conditions preclude Wegovy use, including personal or family history of medullary thyroid carcinoma, multiple endocrine neoplasia syndrome type 2, diabetic retinopathy requiring active treatment, or pregnancy [3]. Our clinical team, supervised by superintendent pharmacist Tarun Kumar (GPhC 2233073), conducts thorough screening to ensure treatment safety.

If you're currently taking other weight loss medications, insulin, or sulfonylureas, your prescriber may need to adjust those treatments before starting Wegovy to prevent hypoglycaemia or drug interactions. This comprehensive assessment typically takes under 3 minutes through our online platform and ensures you receive personalised, safe care.

Age and Special Populations

Wegovy is approved for adults aged 18 and over. It has not been studied in patients over 75, and use in this age group requires careful prescriber consideration of renal function and cardiovascular status [3].

Patients with kidney or liver impairment can typically use Wegovy, though dose adjustments may be necessary based on severity. Your UK prescriber will review any existing conditions and current medications to determine if Wegovy is appropriate for your individual circumstances.

Managing Side Effects Through the Wegovy Dosing Schedule

Gastrointestinal side effects—particularly nausea, diarrhoea, and constipation—are the most commonly reported adverse events with Wegovy, affecting approximately 44%, 30%, and 24% of patients respectively in clinical trials [2]. These typically peak during dose escalation phases and diminish as your body adapts to each new strength.

Practical strategies significantly reduce symptom severity: eat smaller, more frequent meals rather than large portions; avoid high-fat foods that delay gastric emptying further; stay well-hydrated; and inject at a consistent time when you can rest if needed [1][3]. Many patients find that injecting in the evening minimises daytime nausea.

If side effects become intolerable at any dose level, contact your prescriber before your next injection. They may recommend staying at your current dose for an additional month before escalating, or in rare cases, stepping back to the previous dose temporarily. The gradual titration schedule exists precisely to make treatment tolerable—there's no benefit to pushing through severe symptoms.
