Monthly Cost UK: Cheapest Weight Loss Injections

Published on: June 03, 2026

Searching for the cheapest weight loss injections UK monthly cost options? At Cured Pharmacy, we offer transparent upfront pricing on all UK-licensed weight loss treatments including Mounjaro, Wegovy, and Saxenda, with a free clinical consultation completed in under 3 minutes. Our UK-registered prescribers assess your suitability and our prices are guaranteed to be the lowest in the UK — no hidden fees, no surprises.

Understanding Weight Loss Injection Costs in the UK

The monthly cost of weight loss injections varies significantly depending on the active ingredient, dose strength, and treatment phase. At Cured Pharmacy, Saxenda starts from £135.00, Wegovy from £135.00, and Mounjaro from £135.00 — all prices shown before you complete your consultation, ensuring complete transparency.

Unlike many online providers, we display exact pricing upfront rather than requiring you to complete lengthy forms before discovering costs. Our superintendent pharmacist Tarun Kumar (GPhC 2233073) ensures every prescription is clinically appropriate and competitively priced, with all medicines sourced directly from UK-licensed wholesalers [1].

Monthly costs typically increase as you progress through dose escalation schedules, which are designed to minimise side effects while optimising weight loss outcomes. Your UK prescriber will create a personalised titration plan during your free consultation, with clear pricing for each treatment phase.

Mounjaro (Tirzepatide): Dual-Action Weight Loss

Mounjaro contains tirzepatide, the first dual GIP/GLP-1 receptor agonist licensed by the MHRA for weight management in the UK. This dual mechanism activates two complementary metabolic pathways simultaneously, producing superior weight loss compared to single-pathway treatments in head-to-head trials [2].

In the SURMOUNT-1 trial, participants receiving the 15mg maintenance dose achieved an average body weight reduction of 22.5% over 72 weeks — the highest efficacy observed in any obesity medication trial to date [2]. Patients also experienced significant improvements in cardiovascular risk markers including blood pressure, lipid profiles, and inflammatory markers.

At Cured Pharmacy, Mounjaro treatment starts from £135.00 per month, with dose titration beginning at 2.5mg weekly and gradually increasing to your optimal maintenance dose. Each KwikPen contains four pre-measured doses for convenient once-weekly subcutaneous injection.

Who Can Use Mounjaro?

Mounjaro 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. Your UK prescriber will assess your medical history, current medications, and weight loss goals during your free online consultation to determine suitability [3].

Wegovy (Semaglutide): Proven GLP-1 Therapy

Wegovy contains semaglutide, a GLP-1 receptor agonist that mimics the natural hormone glucagon-like peptide-1 to reduce appetite and increase feelings of fullness. Originally developed for type 2 diabetes management, semaglutide was subsequently licensed by the MHRA specifically for chronic weight management at higher therapeutic doses [4].

The STEP clinical trial programme demonstrated that participants on the 2.4mg maintenance dose achieved an average weight reduction of 14.9% over 68 weeks, with 86.4% of participants losing at least 5% of their baseline body weight [4]. Cardiovascular benefits were also observed, including reduced waist circumference and improved glycaemic control in patients with prediabetes.

Available at Cured Pharmacy from £135.00, Wegovy follows a gradual dose escalation schedule starting at 0.25mg weekly and increasing to the 2.4mg maintenance dose over 16-20 weeks. Each pre-filled FlexTouch pen delivers four weekly doses with a simple click-and-inject mechanism.

Wegovy vs Mounjaro: Key Differences

While both are once-weekly injections that suppress appetite through GLP-1 receptor activation, Mounjaro's dual GIP/GLP-1 mechanism typically produces greater absolute weight loss in clinical trials. However, Wegovy offers a lower entry price point and extensive long-term safety data from over a decade of semaglutide use in diabetes management. Your UK prescriber will discuss which option aligns best with your clinical profile and budget during your consultation.

Treatment Active Ingredient Frequency Starting Price
Mounjaro Tirzepatide (dual GIP/GLP-1) Once weekly From £124.99
Wegovy Semaglutide (GLP-1) Once weekly From £69.00
Saxenda Liraglutide (GLP-1) Daily injection From £68.00
Orlistat 120mg Orlistat (lipase inhibitor) Three times daily From £32.00
Xenical Orlistat (lipase inhibitor) Three times daily From £32.00

Saxenda (Liraglutide): Daily Injection Option

Saxenda contains liraglutide, a shorter-acting GLP-1 receptor agonist requiring daily subcutaneous injection rather than weekly administration. First licensed in the UK in 2015, Saxenda offers the longest real-world safety record among GLP-1 weight loss treatments and is often preferred by patients who value gradual dose adjustments [5].

Clinical trials showed that patients on the 3.0mg daily maintenance dose achieved an average weight loss of 8.4 kg over 56 weeks, with 63.2% losing at least 5% of baseline body weight [5]. The daily injection schedule allows for more flexible dose titration, which some patients find helpful for managing gastrointestinal side effects.

Starting from £135.00 at Cured Pharmacy, Saxenda represents the most affordable entry point for prescription weight loss injections in the UK. Each multi-dose pen contains 30 doses, with treatment beginning at 0.6mg daily and increasing by 0.6mg increments weekly until reaching the 3.0mg maintenance dose.

Oral Weight Loss Treatments: Orlistat and Alternatives

For patients who prefer oral medication or have contraindications to injectable treatments, Orlistat offers a clinically proven alternative. Unlike GLP-1 medications that work centrally to reduce appetite, Orlistat acts locally in the digestive system to block approximately 30% of dietary fat absorption [6].

Available in both prescription-strength 120mg formulations (Xenical, generic Orlistat) and lower-dose 60mg over-the-counter options (Alli, Orlos), Orlistat is taken three times daily with meals containing fat. Clinical trials demonstrated an average weight loss of 2.9 kg more than diet and exercise alone over 12 months [6].

At Cured Pharmacy, generic Orlistat 120mg starts from £135.00, Xenical from £135.00, and Orlos 60mg from £135.00 — making oral treatments the most budget-friendly option for weight management. However, efficacy is generally lower than injectable GLP-1 therapies, and gastrointestinal side effects can be significant if dietary fat intake is not properly controlled.

Choosing Between Injectable and Oral Treatments

Injectable GLP-1 medications typically produce greater absolute weight loss but require subcutaneous administration and carry higher monthly costs. Oral Orlistat offers convenience and lower pricing but requires strict adherence to a reduced-fat diet and may cause troublesome gastrointestinal effects. Your UK prescriber will assess your lifestyle, budget, previous weight loss attempts, and medical history to recommend the most appropriate treatment pathway during your free consultation.
