Our Pricing

Published on: June 03, 2026

Accessing prescription weight loss injections UK online has never been more straightforward for eligible patients. At Cured Pharmacy, our UK-registered clinical team provides free consultations for licensed treatments including Mounjaro, Wegovy, and Saxenda, with transparent pricing from £135.00 and discreet next-day delivery across the UK.

Understanding GLP-1 and Dual-Agonist Weight Loss Injections

Prescription weight loss injections work by mimicking natural gut hormones that regulate appetite and blood sugar control. GLP-1 receptor agonists like semaglutide (Wegovy) and liraglutide (Saxenda) have been licensed by the MHRA for weight management in adults with a BMI of 30 or above, or 27 with weight-related health conditions [1].

Tirzepatide (Mounjaro) represents the latest advancement as the UK's first dual GIP/GLP-1 receptor agonist. By activating two hormone pathways simultaneously, clinical trials demonstrated average weight reductions of up to 22.5% over 72 weeks in the SURPASS-3 study — significantly higher than single-pathway treatments [2]. These medications don't simply suppress appetite; they work with your body's natural satiety signals to reduce hunger and improve metabolic function.

All prescription weight loss injections available through Cured Pharmacy require clinical assessment by a UK prescriber. Our superintendent pharmacist Tarun Kumar (GPhC 2233073) ensures every treatment is dispensed in accordance with MHRA guidelines and current NICE recommendations for weight management.

Mounjaro (Tirzepatide): The Dual-Agonist Breakthrough

Mounjaro comes as a pre-filled KwikPen for once-weekly subcutaneous injection. At Cured Pharmacy, genuine UK-licensed Mounjaro is available with transparent upfront pricing, subject to prescriber approval following your free online consultation. The treatment requires ongoing clinical monitoring, and our team provides continuous support throughout your weight management journey.

Clinical Evidence and Efficacy

The SURMOUNT-1 trial enrolled over 2,500 adults with obesity and demonstrated that tirzepatide produced dose-dependent weight loss, with the 15mg dose achieving an average reduction of 20.9% body weight compared to 3.1% with placebo over 72 weeks [2]. Participants also experienced improvements in cardiovascular risk markers including blood pressure, lipid profiles, and inflammatory markers.

Unlike earlier GLP-1 treatments, Mounjaro's dual mechanism targets both GLP-1 and GIP receptors, which may explain its superior efficacy in clinical trials. Patients typically start on a 2.5mg weekly dose, gradually titrating upward to minimise gastrointestinal side effects whilst optimising weight loss outcomes.

Wegovy and Saxenda: Established Semaglutide and Liraglutide Options

Saxenda (liraglutide) offers a daily injection alternative for patients who may benefit from more frequent dosing. Clinical trials demonstrated average weight loss of 8% over 56 weeks when combined with reduced-calorie diet and increased physical activity [4]. Saxenda's daily administration provides flexibility for some patients, though it requires more frequent injections than weekly options. Both Wegovy and Saxenda are available through Cured Pharmacy following clinical assessment by our UK prescribers, with competitive UK pricing and discreet delivery.

Wegovy (Semaglutide) Once-Weekly Injections

Wegovy contains semaglutide, a GLP-1 receptor agonist that has been extensively studied in the STEP clinical trial programme. The STEP 1 trial showed participants achieved an average weight loss of 14.9% over 68 weeks, compared to 2.4% with placebo [3]. Wegovy is administered once weekly via pre-filled pen, starting at 0.25mg and gradually increasing to a maintenance dose of 2.4mg.

Semaglutide works by slowing gastric emptying, reducing appetite, and improving glycaemic control. Common side effects include nausea, diarrhoea, and constipation, which typically diminish as your body adjusts to the medication. Wegovy is licensed for adults with a BMI of 30 or above, or 27 with at least one weight-related comorbidity.

Comparing Prescription Weight Loss Injections: Which Treatment Suits You?

Choosing between Mounjaro, Wegovy, and Saxenda depends on multiple factors including your medical history, weight loss goals, tolerance for side effects, and lifestyle preferences. Mounjaro's dual-agonist mechanism has demonstrated the highest average weight reduction in head-to-head comparisons, but individual responses vary significantly [2][3].

Wegovy offers robust clinical evidence with once-weekly convenience and may be preferred for patients who have previously responded well to GLP-1 treatments. Saxenda's daily dosing provides more frequent reinforcement of appetite control, which some patients find beneficial for adherence to dietary changes. Your UK prescriber will assess your BMI, weight-related health conditions, previous weight loss attempts, and any contraindications before recommending the most appropriate treatment.

Cost considerations also play a role in treatment selection. At Cured Pharmacy, we maintain transparent upfront pricing across all weight loss injections, with no hidden consultation fees. Our lowest price guarantee ensures you're accessing genuine UK-licensed medications at competitive rates, supported by our GPhC-registered clinical team throughout your treatment journey.

Oral Weight Loss Medications: Orlistat and Alternatives

Orlistat may be suitable for patients who prefer oral medication over injections, have contraindications to GLP-1 treatments, or are working toward more modest weight loss goals. At Cured Pharmacy, prescription-strength Orlistat 120mg and Xenical are available following clinical consultation, alongside lower-dose options that can be purchased with pharmacist guidance. All orlistat products require commitment to dietary modification for optimal results and to minimise side effects.

How Orlistat Works Differently from Injectable Treatments

Orlistat (available as prescription-strength 120mg Xenical or lower-dose 60mg Alli and Orlos) works through a completely different mechanism than GLP-1 injections. Rather than affecting appetite hormones, orlistat inhibits pancreatic lipase enzymes, preventing approximately 30% of dietary fat from being absorbed in the intestine [5].

Clinical trials show orlistat produces modest weight loss of 5-10% when combined with a reduced-calorie, lower-fat diet. Side effects are primarily gastrointestinal and directly related to fat intake — patients who consume high-fat meals whilst taking orlistat often experience oily stools, flatulence, and faecal urgency. These effects can be minimised by adhering to a diet containing no more than 30% of calories from fat.
