What Is Saxenda: The UK Guide to Liraglutide Weight Loss Injections

Published on: June 03, 2026

What is Saxenda, and how does it help with weight management in the UK? Saxenda is a prescription weight loss injection containing liraglutide, a GLP-1 receptor agonist licensed by the MHRA for adults with a BMI of 30 or above, or 27 with weight-related health conditions. At Cured Pharmacy, Saxenda is available from £48.00 following a free online clinical assessment by our UK-registered prescribers.

What Is Saxenda and How Does It Work?

What is Saxenda in clinical terms? Saxenda is the brand name for liraglutide 3.0mg, a glucagon-like peptide-1 (GLP-1) receptor agonist that mimics a naturally occurring hormone in your body. This hormone regulates appetite by acting on areas of the brain that control hunger and food intake, helping you feel fuller for longer after meals[1]. Unlike older weight loss medications that block fat absorption, Saxenda works by addressing the hormonal signals that drive overeating.

In clinical trials, patients using Saxenda alongside a reduced-calorie diet and increased physical activity lost an average of 8-9% of their body weight over 56 weeks, compared to 2.6% in the placebo group[2]. The medication is administered once daily via a pre-filled injection pen, with doses gradually increased over five weeks to minimise gastrointestinal side effects. Saxenda is suitable for adults with a BMI of 30 kg/m² or greater, or 27 kg/m² with at least one weight-related comorbidity such as type 2 diabetes or hypertension, subject to prescriber approval[1].

What Is Saxenda Made Of and Who Can Use It?

What is Saxenda's active ingredient? The medication contains liraglutide, a synthetic version of human GLP-1 that is 97% similar to the natural hormone. Each Saxenda pen delivers doses ranging from 0.6mg to 3.0mg, with the maintenance dose being 3.0mg once daily. The solution also contains disodium phosphate dihydrate, propylene glycol, phenol, and water for injections[3].

Saxenda is licensed for use in adults aged 18 and over who meet specific BMI criteria and have unsuccessfully tried other weight management strategies. It is not suitable for individuals with a personal or family history of medullary thyroid carcinoma, those with multiple endocrine neoplasia syndrome type 2, or patients with severe renal or hepatic impairment. Pregnant or breastfeeding women should not use Saxenda, and all patients require a clinical assessment by a UK-registered prescriber before starting treatment[3].

Eligibility Criteria for Saxenda in the UK

To be prescribed Saxenda through Cured Pharmacy, you must be aged 18-75, have a BMI of 30 or above (or 27 with weight-related conditions), and not be pregnant or planning pregnancy. Our superintendent pharmacist, Tarun Kumar (GPhC 2233073), oversees all clinical assessments to ensure patient safety and compliance with MHRA guidelines. The free online consultation takes under three minutes and includes questions about your medical history, current medications, and weight loss goals.

What Is Saxenda's Dosing Schedule and Administration?

What is Saxenda's recommended dosing regimen? Treatment begins with a starting dose of 0.6mg once daily for the first week, increasing by 0.6mg each week until the maintenance dose of 3.0mg is reached in week five[2]. This gradual titration helps your body adjust to the medication and reduces the likelihood of nausea, the most common side effect reported in clinical trials. If you cannot tolerate a dose increase, your prescriber may recommend staying at the current dose for an additional week.

Saxenda is injected subcutaneously into the abdomen, thigh, or upper arm at any time of day, with or without food. Each pen contains enough solution for multiple doses, and you should use a new needle for every injection to maintain sterility. Store unused pens in the refrigerator between 2°C and 8°C, and once in use, they can be kept at room temperature (below 30°C) for up to one month[3]. If you miss a dose, take it as soon as you remember within 12 hours; otherwise, skip it and resume your regular schedule the next day.

What Is Saxenda's Effectiveness Compared to Other Weight Loss Treatments?

What is Saxenda's weight loss outcome compared to newer GLP-1 medications? In the SCALE Obesity and Prediabetes trial, 63.2% of patients on Saxenda lost at least 5% of their body weight, and 33.1% lost at least 10%, significantly higher than placebo[2]. While these results are clinically meaningful, newer dual-action medications like tirzepatide (Mounjaro) have shown greater average weight loss in head-to-head studies, though Saxenda remains a proven and cost-effective option for many patients.

Saxenda offers several advantages: it has been available in the UK since 2015, providing a longer real-world safety profile; it is typically more affordable than newer GLP-1 treatments; and its once-daily dosing allows for flexible timing. At Cured Pharmacy, Saxenda is priced from £48.00 per pen, representing competitive UK pricing with transparent costs shown before your consultation. For patients seeking an established, MHRA-licensed weight loss injection with robust clinical evidence, Saxenda is an excellent choice subject to prescriber approval[4].

Saxenda vs Wegovy: Understanding the Difference

Both Saxenda (liraglutide) and Wegovy (semaglutide) are GLP-1 receptor agonists, but semaglutide has a longer half-life, allowing for once-weekly dosing compared to Saxenda's daily injections. Clinical trials suggest Wegovy may produce slightly greater average weight loss, but Saxenda's daily dosing gives some patients more control over side effect management. Your prescriber will recommend the most suitable option based on your medical history, lifestyle, and treatment goals.

What Is Saxenda's Side Effect Profile and Safety Considerations?

What is Saxenda's most common side effect? Nausea affects approximately 40% of patients, particularly during the dose escalation phase, though it typically improves within a few weeks as your body adapts[2]. Other gastrointestinal effects include diarrhoea, constipation, vomiting, and dyspepsia, which can be managed by eating smaller meals, avoiding high-fat foods, and staying well-hydrated. If side effects persist or become severe, contact your prescriber for advice.

Serious but rare side effects include pancreatitis (inflammation of the pancreas), gallbladder problems, and increased heart rate. In animal studies, liraglutide was associated with thyroid tumours, though no causal link has been established in humans; nonetheless, Saxenda is contraindicated in patients with a personal or family history of medullary thyroid carcinoma[3]. Hypoglycaemia can occur if Saxenda is used alongside insulin or sulfonylureas, so dose adjustments may be necessary. All patients are monitored through follow-up consultations at Cured Pharmacy to ensure safe and effective treatment.
