Saxenda Weight Loss Injections UK Guide

What Is Saxenda and How Does It Work?

Saxenda is a daily prescription-only injectable medication containing the active ingredient liraglutide. This is a GLP-1 receptor agonist which works by slowing digestion and reducing appetite.

It can help make you feel fuller and quicker for longer which results in reduced food intake, resulting in weight loss.

Originally developed for its use in type 2 diabetes, liraglutide was first approved in the UK in 2009, under the brand Victoza. The LEAD trials found a consistent side effect - patients were losing significant weight due to its effects on slowing digestion and reducing hunger.

Following this, further research into its potential as a weight management treatment led to the launch of Saxenda in 2015. This form is now licensed for weight management.

As a GLP-1 receptor agonist, liraglutide helps to

• Slow stomach emptying and,

• Increase feelings of fullness after eating

Collectively, this reduces food intake, appetite and hunger, resulting in weight loss.

Is Saxenda Approved in the UK?

In the UK, all medicines including Saxenda are regulated by the Medicines and Healthcare products Regulatory Agency (MHRA). The MHRA has officially licensed Saxenda as a safe and effective treatment for weight management.

Whilst approved, this does not guarantee access. To be eligible, patients must meet the BMI criteria, not be on interacting medication or suffer from any medical conditions which can be affected by the treatment.

Saxenda is assessed by the National Institute for Health and Care Excellence (NICE) who provides guidance for NHS use.

Currently, NHS access is restricted to patients with the highest clinical need, and only under specialist weight management services. This means it's reserved for those patients who have a higher BMI and suffer from multiple weight-related health conditions.

Access through private clinics, such as Quick Meds is much more flexible, offering wider access to patients with a lower BMI who still meet the licensed threshold.

Who Is Eligible for Saxenda in the UK?

Saxenda can be prescribed for adults with obesity (BMI 30 or over) or who are overweight, (BMI 27 or more) with a weight-related health condition.

Obesity increases the risk of type 2 diabetes amongst other conditions. These are termed weight related health conditions and includes any condition which is caused or worsened by excess weight, and where losing weight would improve these conditions. It includes:

• Type 2 diabetes

• High blood pressure

• High cholesterol

• Cardiovascular disease

• Musculoskeletal problems

• Some cancers

Private clinics such as Quick Meds, offer flexibility and can prescribe to patients who meet this criteria. This may vary between providers as each prescriber uses their own clinical discretion.

NHS criteria is usually much higher than the licensed threshold, reserving treatments for patients with the highest clinical need. Patients may only be prescribed treatment through Tier 3 weight management services in a hospital setting. This involves long waiting lists and may not be available nationwide.

Saxenda Dosage and Daily Injection Schedule

Saxenda is administered as a once-daily injection. The dose starts low and is increased every week as follows:

• Week 1 - 0.6mg once daily

• Week 2 - 1.2mg once daily

• Week 3 - 1.8mg once daily

• Week 4 - 2.4mg once daily

• Week 5 onwards - 3mg once daily

A gradual dose escalation reduces side effects and allows the body to adjust to treatment safely. The maintenance dose is 3mg daily, which follows the initial titration phase.

How Much Weight Can You Lose With Saxenda?

Saxenda was studied in the SCALE clinical trials. The SCALE-1 trial, conducted over 56 weeks involving 3,700 participants showed:

• An average body weight reduction of 8-9%

• Over 60% of participants lost at least 5% of their body weight.

Saxenda is not a ‘magic-pill’ - weight loss outcomes depend on lifestyle changes and can vary between individuals.

Weight loss is usually gradual and does not occur overnight. This is the preferred approach as it is more sustainable long term.

Due to the 5-week ‘titration’ phase, patients usually see:

• First 4 weeks - a small drop in weight as the body adjusts to treatment.

• Week 5 onwards - start to see more results at the maintenance (3mg) dose.

• Within the first year - this is when most people reach their maximum weight loss and start to transition into a ‘maintenance’ phase to keep the weight off long term.

Factors that can influence weight loss results include:

• Consistency - taking the injection at the same time each day.

• Diet - prioritising protein helps maintain muscle mass while you lose fat.

• Exercise - getting a ‘sweat on’ a few times a week.

• Hydration - can help manage minor side effects which may otherwise lead to skipping .

Saxenda Side Effects and Safety

As with all medications, Saxenda can cause side effects though not everyone gets them. As liraglutide affects the digestive system, most of the side effects are related to the gut.

Most common

The most common side effects affecting 1 in 10 people include:

• Nausea

• Vomiting

• Diarrhoea

• Constipation.

These are most likely to occur during the titration phase and usually resolve on their own without treatment.

If they persist, they can be managed by:

• Eating smaller meals - stop as soon as you feel full

• Staying hydrated - helps to prevent headaches and nausea

• Avoiding trigger foods - like greasy or spicy food

• Injection timing - injecting at night may help ‘sleep through’ the worst nausea

Uncommon

Less common side effects can affect between 1 in 100 and 1 in 1,000 people include:

• Pancreatitis - severe abdominal pain that moves to the back

• Gallbladder problems - sharp upper right abdominal pain

• Hypoglycemia (low blood sugar)

• Anaphylaxis - severe allergic reaction. Symptoms include sudden wheeziness, difficulty breathing, swelling of the eyes, face, lips or throat.

If you experience any of these side effects, you should stop using Saxenda and seek immediate medical attention, by calling 999 or going to the nearest A&E.

The patient information leaflet, included with the treatment includes a comprehensive list of side effects.

Saxenda vs Wegovy and Mounjaro

Other weight loss injections available are Mounjaro and Wegovy. All three treatments are injectable medicines, but differ in how they work, how often they are used, and the average weight loss seen in clinical trials.

Whilst Saxenda is taken daily, both Wegovy and Mounjaro are administered as a weekly injection. All three treatments activate GLP-1 with Mounjaro additionally activating GIP, which appears to be more effective at helping with weight loss.

Whilst the newer treatments may lead to greater weight loss, Saxenda remains a popular choice for those who:

• Require flexibility. As it's taken daily, you have more control. If treatment needs to be paused due to side effects or a procedure, it leaves the body more quickly than the weekly injections.

• Proven track record. Saxenda has been used for weight management longer than Wegovy or Mounjaro, giving more long-term data.

• Availability. During global shortages of weekly injections, Saxenda stock levels have sometimes been more stable in the UK.

Can You Get Saxenda on the NHS?

Whilst approved for use in the UK, getting Saxenda on the NHS is not straightforward. It is not prescribed the way most routine medications are and is only available through limited NHS pathways.

To access Saxenda on the NHS, patients must follow a tiered pathway:

• Tier 1 & 2 - GP refers patients to specialist lifestyle services. This involves 6-12 months of supervised diet and exercise programmes in your community

• Tier 3 - If community pathways aren’t successful, you can be referred to a Tier 3 service. This may be based in a hospital or a specialist clinic.

Currently, the NHS only offers Saxenda through Tier 3 weight management services and access is limited. Patients are prioritised based on the highest clinical need. Usually this means having a much higher BMI than the licensed threshold and having multiple weight related health conditions.

Access also depends on where you live. Not all areas have a funded Tier 3 service, leading to a varying availability across the country. Additionally, due to high demand and limited clinic capacity, as of 2026 waiting lists can range from 6 months to over 2 years.

Getting Saxenda Privately in the UK

If you are looking to start Saxenda straight away, or don't meet strict NHS criteria, you can access treatment through private clinics like Quick Meds, where access is more readily available.

Whilst faster, a prescription from a private clinic still requires a clinical assessment. This ensures the medication is safe and appropriate for you.

How it works:

• Clinical assessment - The patient fills out a medical questionnaire asking about weight, medical history and if other medicines are taken.

• Independent verification - The clinic must verify information, and may request a photo to verify weight or check NHS records (required by law)

• Ongoing monitoring - Progress should be monitored by a clinician to track weight loss and manage side effects.

Private providers can prescribe Saxenda to eligible patients whilst staying within the licensed framework. Safety is the priority when prescribing any treatment, whether privately or through the NHS.

To ensure you are requesting treatment from a genuine provider, you can look for:

• GPhC registration - all pharmacies, including online pharmacies must be GPhC registered. Look out for regulatory information and verify this.

• Transparent pricing - be wary of prices that seem too good to be true.

Red flags to avoid:

• No consultation - avoid websites that bypass the clinical consultation process.

• Social media sellers - it is illegal to sell prescription medication through any social media platform

• Lack of contact details - a legitimate UK clinic should provide a physical address of the clinic and a way to speak to the healthcare professional.

Saxenda Cost in the UK

The cost of Saxenda depends on how the treatment is accessed.

The price difference is mainly due to how the medication is funded. On the NHS, the cost is subsidised by the government, attracting a fixed monthly fee.

On a private prescription, you pay the full market price which can vary between providers. The higher cost usually includes the medication and monitoring fees. Additionally, some providers may charge a consultation and packaging fee.

Cost Breakdown

When buying privately, you essentially pay for each pen. As a daily injection, the number of pens needed increases as you reach the maintenance dose.

• Month 1(titration) - During this phase, the dose is low. A pack of 5 pens can last up to 6 weeks, costing between £150 - £180

• Maintenance (3.0mg) - Once at the maintenance dose, one pen lasts 6 days. You will usually need 5 pens per month, increasing the cost to between £200 and £250.

The pricing usually includes the medication, the clinical assessment, and a sharps bin for needle disposal.

Factors affecting the price

How much you pay each month can vary depending on:

• The provider: Each clinic has their own prices. Most patients shop around for a good deal.

• Generic Liraglutide: Some providers have started to provide the non-branded form, sometimes called Nevolat. This is usually more affordable compared to Saxenda.

• Additional support: Some providers offer 1-to-1 coaching or tailored nutritional advice.

Whilst NHS prescriptions reduce the cost to patients, access is limited, prompting most to seek a private provider.

Lifestyle Changes Needed With Saxenda

Whilst an effective tool, Saxenda works best with lifestyle changes. The medication handles the food noise whilst lifestyle adjustments and behaviour change help to support long-term results, preventing weight regain once you come off treatment.

Any weight management plan should include and emphasise diet and exercise changes. Saxenda is not a ‘magic pill’ and without these changes, your results can be affected.

To get the most out of your treatment, focus on:

• Eating patterns and behaviours - Saxenda slows digestion keeping you fuller for longer, so It's expected to not feel as hungry. Stick to eating only at the times your body needs it (i.e. in response to hunger) rather than eating three square meals a day regardless of hunger cues.

• Diet and food groups - Stick to the meals you enjoy but focus on foods high in protein and fibre, but low in carbohydrates. This can help maintain the food choices going forward.

• Exercise - Whilst there's no such thing as an ineffective workout, to tune your body to burn fat and lose weight, it's important to push yourself beyond your current comfort zone. Aim to break a sweat or get out of breath, through exercise you enjoy. Strength training in particular can help reduce the risk of losing muscle.

• Hydration - Ensuring you remain hydrated can help minimise the risk of side effects whilst also contributing to fullness levels.
