Wegovy Cost Per Month vs Mounjaro: Complete UK Comparison

Understanding wegovy cost per month vs mounjaro uk pricing is essential when choosing your weight loss treatment. At Cured Pharmacy, Wegovy starts from £135.00 and Mounjaro from £135.00, with transparent upfront pricing and free clinical consultations from UK-registered prescribers. Both treatments require a prescription following online assessment, typically completed in under three minutes.

Monthly Cost Breakdown: Wegovy vs Mounjaro UK

Wegovy (semaglutide) is available at Cured Pharmacy from £135.00 offering one of the most competitive UK pricing structures for this MHRA-licensed weight loss injection [1]. The monthly cost varies depending on your prescribed dose, which increases gradually during the titration phase from 0.25mg to a maintenance dose of 2.4mg once weekly.

Mounjaro (tirzepatide) starts from £135.00 at Cured Pharmacy. Whilst the upfront cost is higher than semaglutide-based treatments, clinical trial data shows tirzepatide achieved average weight reductions of 22.5% over 72 weeks in the SURPASS-3 trial — significantly greater than semaglutide's 14.9% in STEP-1 [2][3]. Your UK prescriber will determine the appropriate starting dose based on your medical history and weight loss goals.

Both treatments follow a dose-escalation schedule, meaning your monthly cost may change as you progress through treatment phases. All prices at Cured Pharmacy are displayed before consultation, ensuring complete transparency with no hidden fees for prescriber assessment or delivery.

How Mounjaro and Wegovy Work Differently

Mounjaro contains tirzepatide, the first dual GIP/GLP-1 receptor agonist licensed by the MHRA for weight management in the UK [2]. This dual-action mechanism activates both glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, producing enhanced effects on appetite regulation, insulin secretion, and energy expenditure compared to single-pathway treatments.

Wegovy contains semaglutide, a selective GLP-1 receptor agonist that mimics the natural GLP-1 hormone [1]. It works by slowing gastric emptying, reducing appetite signals in the brain, and improving insulin sensitivity. The STEP clinical trial programme demonstrated consistent weight loss across diverse patient populations, with participants losing an average of 14.9% body weight over 68 weeks [3].

Both medications are administered as once-weekly subcutaneous injections using pre-filled pens. The key clinical difference lies in tirzepatide's dual receptor activation, which may explain the greater weight reductions observed in head-to-head comparative studies, though individual responses vary significantly [4].

Clinical Trial Evidence

The SURPASS-2 trial directly compared tirzepatide against semaglutide 1mg in patients with type 2 diabetes, finding superior weight loss with all tirzepatide doses (ranging from 7.6kg to 11.2kg versus 5.7kg with semaglutide) [4]. Whilst these trials focused on diabetic populations, the SURMOUNT programme has since confirmed similar efficacy patterns in non-diabetic adults with obesity.

STEP-1, the pivotal trial for Wegovy, enrolled 1,961 adults with obesity or overweight plus weight-related comorbidities. After 68 weeks, 83.5% of participants on semaglutide 2.4mg achieved at least 5% weight loss, compared to 31.1% on placebo [3]. Both treatments demonstrate clear clinical benefit when combined with reduced-calorie diet and increased physical activity.

Wegovy Cost Per Month vs Mounjaro: Which Offers Better Value?

Value assessment extends beyond the initial price point. Wegovy's lower starting cost makes it accessible for patients beginning their weight loss journey, whilst Mounjaro's enhanced efficacy profile may represent better long-term value for those who achieve greater weight reduction and potentially shorter treatment duration.

Clinical outcomes should guide your decision alongside cost. In the SURMOUNT-1 trial, 63% of participants on the highest tirzepatide dose (15mg) achieved at least 20% body weight reduction, compared to 1.3% on placebo [5]. No semaglutide trial has demonstrated comparable proportions reaching this threshold, suggesting Mounjaro may deliver more substantial results for some patients.

Your UK prescriber at Cured Pharmacy will assess your BMI, weight loss history, medical conditions, and treatment goals during the free online consultation. Factors including previous medication responses, budget considerations, and target weight loss percentage all influence which treatment offers optimal value for your individual circumstances.

Treatment Duration and Total Cost

Most clinical guidelines recommend continuing weight loss medication for at least 12 months to achieve and maintain optimal results. Based on Cured Pharmacy pricing, a 12-month course would cost approximately £135.00 for Mounjaro versus £135.00 for Wegovy at maintenance doses, though actual costs vary with prescribed strength.

Consider that greater weight loss may allow earlier transition to maintenance therapy or lifestyle management alone. The National Institute for Health and Care Excellence (NICE) recommends reviewing treatment continuation at 6 months, discontinuing if patients haven't achieved at least 5% weight loss [6]. Both medications have demonstrated weight maintenance benefits when continued long-term in clinical trials.

Eligibility and Prescribing Criteria in the UK

Both Wegovy and Mounjaro are prescription-only medicines in the UK, requiring clinical assessment by a registered prescriber before dispensing. NICE guidance recommends GLP-1 receptor agonists for adults with BMI ≥35 kg/m² (or ≥32.5 kg/m² for people from South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean family backgrounds) alongside intensive lifestyle support [6].

Patients with BMI 30-34.9 kg/m² may be considered if they have weight-related comorbidities such as type 2 diabetes, hypertension, dyslipidaemia, obstructive sleep apnoea, or cardiovascular disease. Your prescriber will review your full medical history, current medications, and contraindications during the online consultation at Cured Pharmacy.

Absolute contraindications include personal or family history of medullary thyroid carcinoma, multiple endocrine neoplasia syndrome type 2, and pregnancy or breastfeeding. Relative contraindications requiring careful assessment include diabetic retinopathy, history of pancreatitis, severe gastrointestinal disease, and renal impairment [1][2]. Our clinical team ensures safe, appropriate prescribing aligned with MHRA licensing and professional guidelines.

Side Effects and Tolerability Comparison

Gastrointestinal side effects are the most commonly reported adverse events with both medications. In clinical trials, nausea occurred in 44% of Wegovy patients versus 11% on placebo, whilst 31% of Mounjaro patients (15mg dose) experienced nausea versus 8% on placebo [3][5]. These effects typically diminish over time as your body adjusts to treatment.

The dose-escalation schedules for both medications are specifically designed to improve tolerability. Wegovy increases from 0.25mg weekly to 2.4mg over 16-20 weeks, whilst Mounjaro escalates from 2.5mg to maintenance doses of 5mg, 10mg, or 15mg over similar timeframes. Starting low and increasing gradually significantly reduces the severity and duration of gastrointestinal symptoms.

Other reported side effects include constipation, diarrhoea, vomiting, abdominal pain, and injection site reactions. Serious adverse events are rare but include pancreatitis, gallbladder disease, and hypoglycaemia (particularly in patients taking other glucose-lowering medications). Our superintendent pharmacist, Tarun Kumar (GPhC 2233073), and clinical team provide comprehensive safety information and ongoing monitoring support throughout your treatment journey.

Managing Side Effects Effectively

Most patients find gastrointestinal symptoms manageable with simple dietary modifications. Eating smaller, more frequent meals, avoiding high-fat foods, staying well-hydrated, and allowing adequate time between eating and lying down can significantly reduce nausea and reflux symptoms.

If side effects become troublesome, your prescriber may recommend maintaining your current dose for an additional week before escalating, or in some cases, reducing to the previous dose temporarily. Never adjust your dose without consulting your prescriber, as the titration schedule is carefully designed to balance efficacy with tolerability.

What to Expect in Your First Month

During the initial weeks, you'll start on the lowest dose to allow your body to adjust. Weight loss during this phase is typically modest (1-2kg), as the primary goal is establishing tolerability rather than maximum efficacy. As you progress through dose escalation, weight loss typically accelerates, with most patients seeing significant results by months 3-6.

Keep a simple log of your weekly weight, any side effects experienced, and how you're managing dietary changes. This information helps your prescriber make informed decisions about dose progression and provides valuable insight into your treatment response. Remember that weight loss medications work best when combined with sustainable lifestyle modifications including balanced nutrition and regular physical activity.
