Wegovy vs Mounjaro Cost UK: Complete Price Breakdown

Published on: June 03, 2026

When comparing wegovy vs mounjaro cost uk, understanding both upfront pricing and long-term value is essential for making an informed decision. At Cured Pharmacy, we provide transparent pricing on both medications — Wegovy from £135.00 and Mounjaro from £124.99 — with no hidden fees and a free online consultation with UK-registered prescribers.

Wegovy vs Mounjaro Cost UK: Direct Price Comparison

Mounjaro (tirzepatide) is priced from £135.00 at Cured Pharmacy, reflecting its status as the newest dual-action weight loss injection licensed by the MHRA. This pricing includes your medication, clinical assessment, and discreet home delivery across the UK.

Wegovy (semaglutide) starts from £20 off first order using code WEIGHTLOSSNEW[1].

When evaluating cost, it's important to consider efficacy data alongside pricing. Clinical trials demonstrate that both medications produce significant weight loss, though tirzepatide showed higher average reductions in the SURMOUNT-1 trial compared to semaglutide's STEP programme results [1][2].

How Mounjaro and Wegovy Work Differently

Mounjaro contains tirzepatide, the first dual GIP/GLP-1 receptor agonist approved for weight management in the UK. By activating both glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, it targets appetite regulation and glucose metabolism through two complementary pathways [1].

Wegovy contains semaglutide, a selective GLP-1 receptor agonist that mimics the natural hormone GLP-1. This single-pathway approach reduces appetite, slows gastric emptying, and improves glycaemic control, with extensive clinical evidence supporting its efficacy in weight management [2].

The dual-action mechanism of tirzepatide may explain why SURMOUNT-1 participants achieved average weight reductions of up to 22.5% at the highest dose over 72 weeks, compared to average reductions of 14.9% with semaglutide 2.4mg in the STEP 1 trial [1][2]. However, individual responses vary, and your UK prescriber will recommend the most appropriate treatment based on your medical history and weight loss goals.

Dosing Schedules and Administration

Both medications are administered as once-weekly subcutaneous injections using pre-filled pens. Mounjaro is available in doses ranging from 2.5mg to 15mg, with gradual titration every four weeks to minimise gastrointestinal side effects [3]. Wegovy follows a similar escalation protocol, starting at 0.25mg and increasing to a maintenance dose of 2.4mg over approximately 16-20 weeks [4].

The convenience of weekly dosing makes both treatments more manageable than daily injection alternatives like Saxenda (liraglutide). Your prescriber will provide detailed administration guidance and monitor your progress throughout treatment.

Clinical Evidence: Efficacy and Safety Data

The SURMOUNT-1 trial evaluated tirzepatide in 2,539 adults with obesity or overweight with weight-related comorbidities. Participants receiving the 15mg dose achieved a mean weight reduction of 22.5% over 72 weeks, with 63% achieving at least 20% weight loss [1]. These results represent the highest efficacy data for any approved weight management medication in clinical trials.

Wegovy's efficacy was established in the STEP clinical programme, which enrolled over 4,500 participants across multiple trials. In STEP 1, adults receiving semaglutide 2.4mg achieved a mean weight reduction of 14.9% at 68 weeks, with 50.5% achieving at least 15% weight loss [2]. Both medications demonstrated improvements in cardiometabolic risk factors including blood pressure, lipid profiles, and glycaemic markers.

Common side effects for both medications include nausea, diarrhoea, vomiting, and constipation, typically occurring during dose escalation and diminishing over time [3][4]. Serious adverse events are rare but include pancreatitis risk and potential thyroid concerns, which your prescriber will discuss during consultation. Both medications are contraindicated in patients with personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2.

Long-Term Weight Maintenance

Clinical data from extension studies suggest that continued treatment is necessary to maintain weight loss, with significant weight regain observed after discontinuation [5]. Your UK prescriber will work with you to develop a sustainable treatment plan incorporating dietary modifications, physical activity, and behavioural strategies alongside medication therapy.

NICE guidance recommends GLP-1 receptor agonists as part of a comprehensive weight management programme, not as standalone therapy. At Cured Pharmacy, our clinical team provides ongoing support to optimise your treatment outcomes and help you achieve lasting results.

Who Can Use Mounjaro and Wegovy?

Both Mounjaro and Wegovy are licensed in the UK 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 hypertension, type 2 diabetes, or dyslipidaemia [6]. Your eligibility is determined during a clinical assessment with a UK-registered prescriber, who will review your medical history, current medications, and weight loss goals.

These medications are not suitable for everyone. Contraindications include pregnancy or breastfeeding, personal or family history of medullary thyroid carcinoma, Multiple Endocrine Neoplasia syndrome type 2, and severe gastrointestinal disease. Your prescriber will also assess for potential drug interactions, particularly if you take medications with narrow therapeutic indices or those affected by delayed gastric emptying [3][4].

Treatment requires commitment to lifestyle modifications including a reduced-calorie diet and increased physical activity. Clinical trials enrolled participants who received nutritional counselling and behavioural support alongside medication, and similar comprehensive approaches are recommended in UK clinical practice.

We also offer flexible payment options and discreet billing to protect your privacy.

Alternative Weight Loss Treatments Available

While Mounjaro and Wegovy represent the most effective pharmacological options currently available, Cured Pharmacy offers a range of weight loss treatments to suit different clinical needs and budgets. Saxenda (liraglutide) is a daily GLP-1 injection that may be appropriate for patients who prefer more gradual dose adjustments or have specific clinical considerations.

For patients seeking non-injectable options, we offer Orlistat and Xenical (orlistat 120mg), which work by reducing dietary fat absorption in the intestine. These medications are suitable for patients with lower BMI thresholds and produce modest weight loss of approximately 5-10% when combined with dietary changes [7]. Orlistat-based treatments require adherence to a reduced-fat diet to minimise gastrointestinal side effects.

Your UK prescriber will discuss all suitable options during your consultation, considering your medical history, weight loss goals, previous treatment responses, and personal preferences. There is no single best treatment — the optimal choice depends on your individual circumstances and clinical profile.

Combining Medication with Lifestyle Changes

All prescription weight loss medications are most effective when used alongside dietary modifications and increased physical activity. NICE recommends a multicomponent intervention approach that addresses eating behaviours, physical activity levels, and psychological factors contributing to weight gain [6].

At Cured Pharmacy, we provide educational resources and ongoing support to help you maximise your treatment outcomes. Your prescriber may recommend working with a registered dietitian or enrolling in a structured weight management programme to complement your medication therapy and develop sustainable healthy habits.
