Published on: June 03, 2026

When comparing saxenda vs mounjaro monthly cost uk, understanding the full financial commitment is essential for sustainable weight management. At Cured Pharmacy, we offer transparent upfront pricing on both treatments: Saxenda from £135.00 and Mounjaro from £124.99 with all costs disclosed before your free clinical consultation with a UK-registered prescriber.

Saxenda vs Mounjaro Monthly Cost UK: Direct Price Comparison

The monthly cost difference between these two prescription weight loss injections reflects their distinct dosing schedules and clinical profiles. Saxenda (liraglutide) requires daily injections, whilst Mounjaro (tirzepatide) is administered once weekly, affecting both convenience and overall expenditure [1].

At Cured Pharmacy, Saxenda starts from £135.00 and Mounjaro from £124.99 per treatment cycle. Your final monthly cost depends on your prescribed maintenance dose, which your UK prescriber determines based on your individual response and tolerability during the titration phase [2]. All prescription medications require clinical assessment by a UK-registered prescriber before dispensing.

Many patients find that whilst Mounjaro carries a higher upfront cost, the once-weekly dosing schedule and superior weight reduction outcomes observed in clinical trials may offer better long-term value [3]. Your prescriber will discuss both options during your free consultation to identify the most suitable and sustainable treatment for your circumstances.

How Saxenda and Mounjaro Work Differently

Saxenda contains liraglutide, a GLP-1 receptor agonist that mimics a natural gut hormone to reduce appetite and slow gastric emptying [1]. It has been licensed in the UK since 2015 and requires daily subcutaneous injection at a maintenance dose of 3.0mg.

Mounjaro contains tirzepatide, the first dual GIP/GLP-1 receptor agonist approved by the MHRA for weight management [3]. By activating both glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, tirzepatide produces enhanced metabolic effects compared to single-pathway agents.

In the SURMOUNT-1 trial, participants receiving the highest tirzepatide dose achieved an average 22.5% body weight reduction over 72 weeks, compared to 15.8% with semaglutide 2.4mg in the STEP-1 trial [3][4]. These differences in efficacy may influence your cost-benefit analysis when choosing between treatments.

Clinical Trial Outcomes

Saxenda demonstrated an average 8% body weight reduction over 56 weeks in the SCALE Obesity and Prediabetes trial, with 63.2% of participants achieving at least 5% weight loss [1]. Mounjaro's SURMOUNT trials showed 89% of participants on the 15mg dose achieved at least 5% weight loss, with 57% reaching 20% or greater reduction [3].

These outcomes represent averages from controlled clinical trials. Individual results vary based on adherence, lifestyle modifications, baseline metabolic health, and genetic factors. Your UK prescriber will set realistic expectations during your consultation.

Dosing Schedules and Their Impact on Monthly Costs

Saxenda's daily injection requirement means you'll use one pen every 6 days at the maximum 3.0mg maintenance dose, translating to approximately five pens monthly. The treatment begins with a gradual dose escalation over five weeks to minimise gastrointestinal side effects [1].

Mounjaro's once-weekly schedule means four injections per month at maintenance doses ranging from 5mg to 15mg, depending on your response and tolerability [3]. The titration phase typically spans 16-20 weeks, with dose increases every four weeks as clinically appropriate.

When calculating saxenda vs mounjaro monthly cost uk, factor in the complete treatment duration. Most clinical trials evaluated these medications over 56-72 weeks, and many patients require ongoing treatment to maintain weight loss [1][3]. Your prescriber will discuss realistic timelines during your assessment.

Titration Phase Considerations

Both treatments require gradual dose escalation to improve gastrointestinal tolerability. Saxenda starts at 0.6mg daily, increasing by 0.6mg weekly until reaching 3.0mg [1]. Mounjaro begins at 2.5mg weekly, increasing by 2.5mg increments every four weeks up to a maximum of 15mg [3].

Your costs during the titration phase may differ from maintenance pricing, as lower doses typically use less medication. Cured Pharmacy provides transparent pricing for each dose strength before you complete your clinical assessment.

Additional Costs Beyond Medication Price

At Cured Pharmacy, your clinical consultation is completely free, with no hidden assessment fees or subscription charges. Unlike some providers, we display all treatment costs upfront before you begin your consultation, ensuring complete transparency.

You'll need to budget for injection supplies if not included with your pen device. Both Saxenda and Mounjaro use pre-filled pens with attached needles, though some patients prefer to use their own needles for comfort. Standard 4mm or 6mm pen needles are widely available and typically cost under £124.99 for a month's supply.

Consider potential costs for managing side effects, though most gastrointestinal symptoms resolve within the first few weeks of treatment [1][3]. Your prescriber may recommend over-the-counter remedies for nausea or constipation during the initial titration phase. Always inform your prescriber of any persistent or severe side effects.

Which Treatment Offers Better Value for UK Patients?

Value assessment extends beyond monthly cost to include efficacy, convenience, tolerability, and long-term sustainability. Patients who achieve greater weight loss may reach their goals faster, potentially reducing total treatment duration and overall expenditure.

Mounjaro's once-weekly dosing schedule offers significant lifestyle advantages for patients who travel frequently, work irregular shifts, or struggle with daily medication adherence [3]. This convenience factor may justify the higher monthly cost for some individuals.

Saxenda's lower entry price point makes it accessible for patients with tighter budgets or those wanting to trial GLP-1 therapy before committing to higher-cost options [1]. Many UK prescribers recommend starting with Saxenda and transitioning to Mounjaro if weight loss plateaus or daily injections become burdensome.

Factors Your Prescriber Will Consider

Your UK prescriber evaluates multiple factors when recommending between Saxenda and Mounjaro, including your BMI, weight loss goals, previous treatment history, medical contraindications, and budget constraints. Both medications require a BMI of 30 kg/m² or above, or 27 kg/m² with weight-related comorbidities such as type 2 diabetes or hypertension.

If you have type 2 diabetes, Mounjaro may offer additional glycaemic control benefits due to its dual-receptor mechanism [3]. Conversely, if you have a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2, neither medication is appropriate. Your prescriber will conduct a thorough medical assessment during your consultation.
