Weight Loss Injections Monthly Cost UK

Published on: June 03, 2026

Understanding weight loss injections monthly cost UK is essential when choosing the right treatment for your weight management goals. At Cured Pharmacy, we offer transparent upfront pricing on all UK-licensed weight loss injections, with Saxenda starting from £135.00 Wegovy from £135.00 and Mounjaro from £135.00 per month, subject to prescriber approval.

How Much Do Weight Loss Injections Cost Per Month in the UK?

Monthly costs for weight loss injections in the UK vary significantly depending on the active ingredient, dosage strength, and frequency of administration. At Cured Pharmacy, Saxenda (liraglutide) starts from £135.00 per month for daily injections, Wegovy (semaglutide) from £135.00 for once-weekly dosing, and Mounjaro (tirzepatide) from £135.00 for weekly administration [1]. All prices include free clinical consultation with a UK-registered prescriber.

The dose you're prescribed directly impacts your monthly cost. Most patients begin on a lower starter dose and gradually titrate upwards over 16-20 weeks to reach their maintenance dose, as recommended by NICE guidelines [2]. Your final monthly cost depends on the maintenance dose your prescriber determines is clinically appropriate based on your response to treatment and tolerability.

Unlike some pharmacies that advertise low introductory prices, Cured Pharmacy displays transparent pricing for all dose strengths before you begin your consultation. This means no hidden fees or unexpected price increases as you progress through your treatment programme.

Mounjaro Monthly Cost UK: What to Expect

Mounjaro (tirzepatide) is the newest weight loss injection licensed in the UK by the MHRA, offering the highest average weight reduction in clinical trials. At Cured Pharmacy, Mounjaro starts from £135.00 per month, making it competitively priced compared to typical UK market rates for this dual GIP/GLP-1 receptor agonist [3].

In the SURMOUNT-1 trial, patients taking the 15mg maintenance dose of tirzepatide achieved an average 22.5% body weight reduction over 72 weeks — significantly higher than single-pathway GLP-1 treatments [3]. The treatment is administered as a single subcutaneous injection once weekly using the convenient KwikPen pre-filled device.

Your prescriber will start you on a 2.5mg dose and gradually increase every four weeks, typically reaching a maintenance dose between 5mg and 15mg depending on your clinical response and tolerability. Each dose strength is priced transparently at Cured Pharmacy, so you'll know your expected monthly cost throughout your treatment journey.

Is Mounjaro Worth the Monthly Cost?

Clinical trial data suggests tirzepatide produces superior weight loss outcomes compared to semaglutide-based alternatives, which may justify the higher monthly investment for patients who haven't achieved their goals with other treatments [3][4]. However, the best treatment is always the one you can afford consistently and tolerate well — your UK prescriber will discuss all suitable options during your free consultation.

Wegovy Monthly Cost UK: Affordable Weekly Injections

Wegovy (semaglutide 2.4mg) offers proven weight loss efficacy at a lower monthly cost than tirzepatide. At Cured Pharmacy, Wegovy starts from £135.00 per month — previously £135.00 now reduced to provide better value for UK patients seeking once-weekly GLP-1 treatment.

The STEP-1 clinical trial demonstrated that adults taking semaglutide 2.4mg achieved an average 14.9% body weight reduction over 68 weeks, compared to 2.4% with placebo [4]. This makes Wegovy one of the most extensively studied weight loss medications available in the UK, with robust long-term safety data.

Like all GLP-1 treatments, Wegovy requires dose escalation. You'll begin on 0.25mg weekly and increase every four weeks until reaching the 2.4mg maintenance dose at week 17. Each pen contains four pre-filled doses, and your monthly cost remains consistent once you reach your maintenance dose, subject to prescriber approval.

Wegovy vs Mounjaro: Monthly Cost Comparison

While Mounjaro showed higher average weight loss in head-to-head trials, Wegovy remains an excellent choice for many patients due to its lower monthly cost and well-established safety profile [3][4]. Your prescriber will consider your medical history, weight loss goals, budget, and previous treatment responses when recommending the most suitable option during your consultation.

Saxenda Monthly Cost UK: Daily Injection Alternative

Saxenda (liraglutide 3mg) is the most affordable prescription weight loss injection at Cured Pharmacy, starting from £135.00 per month. Unlike weekly injections, Saxenda requires daily subcutaneous administration, which some patients prefer for more consistent appetite control throughout the day.

In the SCALE Obesity and Prediabetes trial, patients using liraglutide 3mg achieved an average 8% body weight reduction over 56 weeks, with 63.2% of participants losing at least 5% of their baseline weight [5]. While the average weight loss is lower than newer GLP-1 treatments, Saxenda remains clinically effective for many UK patients and is often prescribed when weekly injections aren't suitable.

Each Saxenda pen contains 18mg of liraglutide, providing six days of treatment at the maximum 3mg daily dose. You'll need approximately five pens per month once you reach your maintenance dose. The lower upfront monthly cost makes Saxenda an accessible option for patients beginning their weight loss journey, subject to prescriber approval.

What Affects Your Monthly Weight Loss Injection Cost?

Several factors determine your final monthly cost for weight loss injections in the UK. The most significant is your prescribed maintenance dose — higher doses naturally cost more, but they're only prescribed when clinically necessary based on your response to lower doses and tolerability profile.

Frequency of administration also impacts monthly costs. Daily injections like Saxenda require more pens per month than weekly treatments like Wegovy or Mounjaro, though the per-dose cost differs. Your body weight, treatment goals, and medical history all influence which medication and dose your UK prescriber recommends during your clinical assessment.

At Cured Pharmacy, there are no hidden consultation fees, prescription charges, or delivery costs added after your assessment. The price you see for each dose strength is the complete monthly cost you'll pay, making it easier to budget for long-term weight management treatment.

Does Insurance Cover Weight Loss Injections?

Most private health insurance policies in the UK do not cover weight loss medications, as they're typically classified as lifestyle treatments rather than essential medical care. However, some employers offer enhanced health plans that may provide partial coverage — check your policy documents or contact your insurer directly to confirm eligibility.
