SaxendaLiraglutide · GLP-1 receptor agonist

What is Saxenda?

Saxenda is the brand name for liraglutide 3.0 mg, a once-daily injection licensed in the UK for weight management. Like the weekly treatments it acts on the GLP-1 receptor to reduce appetite and slow gastric emptying, but liraglutide has a shorter duration of action, which is why it must be injected every day rather than once a week.

How Saxenda works

Liraglutide mimics GLP-1, the hormone the gut releases after eating, reducing hunger and slowing the rate at which the stomach empties.

Its duration of action is shorter than semaglutide or tirzepatide. A daily injection maintains the signal that the weekly treatments sustain with a single dose.

In trials, liraglutide produced smaller average weight reduction than the weekly treatments. It remains a licensed option, and daily dosing suits some people better, a smaller daily adjustment can be easier to tolerate than a larger weekly one.

How Liraglutide actsThe molecule activates the GLP-1 receptor, which reduces the appetite signal, slows gastric emptying and matches the insulin response to the meal.LiraglutideGLP-1receptorAppetite signal reducedStomach empties more slowlyInsulin response matched to the meal

Who it may suit

May be considered for

  • Adults meeting the BMI thresholds set out in NICE guidance, assessed individually
  • People whose weight is associated with a weight-related health condition
  • People who can commit to a daily injection routine

Not suitable if

  • Personal or family history of medullary thyroid carcinoma, or Multiple Endocrine Neoplasia syndrome type 2
  • Pregnancy, breastfeeding, or planning to conceive
  • Previous hypersensitivity to liraglutide
  • History of pancreatitis, requiring individual assessment

Dosage and titration

StepDoseTiming
Week 10.6 mgOnce daily
Week 21.2 mgOnce daily
Week 31.8 mgOnce daily
Week 42.4 mgOnce daily
Maintenance3.0 mgOnce daily, from week 5

Escalation is weekly rather than four-weekly, reaching the 3.0 mg maintenance dose after about five weeks, considerably faster than the weekly treatments. A prescriber may slow this if side effects require it.

Side effects

Common Usually mild

  • Nausea, particularly during dose escalation
  • Diarrhoea or constipation
  • Vomiting
  • Headache and fatigue
  • Reduced appetite and indigestion
  • Injection-site reactions, which can be more noticeable with daily injection

Serious Seek advice

  • Pancreatitis, severe, persistent abdominal pain that may radiate to the back
  • Gallbladder problems, including gallstones
  • Severe or persistent vomiting leading to dehydration
  • Allergic reaction, swelling of the face, lips or throat
  • Low blood sugar, particularly alongside insulin or a sulfonylurea

As with other GLP-1 receptor agonists, rodent studies showed thyroid C-cell tumours; whether this occurs in humans is unknown, which is why a personal or family history of medullary thyroid carcinoma is a contraindication.

Interactions

  • Oral medicines: delayed gastric emptying can alter absorption. Tell your prescriber everything you take.
  • Insulin and sulfonylureas: increased risk of low blood sugar; doses may need adjusting.
  • Alcohol: can worsen nausea and affect blood glucose.

Storage

Store in a refrigerator at 2–8°C before first use, protected from light. Do not freeze. After first use, follow the patient information leaflet supplied with your pen for the permitted storage period and temperature.

How to get Saxenda, and what it costs

Saxenda is a prescription-only medicine. It cannot be bought over the counter, from a supplement retailer, or from any website that sells it without an assessment, those are not legitimate suppliers, and what arrives from them is of unverified identity and strength.

The route is the same wherever you obtain it legitimately: a clinical assessment, review by a named prescriber, and supply from a registered pharmacy only if treatment is judged appropriate for you. There is no lawful shortcut around that step, and a provider offering one is telling you something useful about itself.

Cost varies by provider, by dose and by market, and is discussed after assessment rather than advertised, prescription-only medicines cannot be promoted to the public with pricing. What you can establish before committing is whether a provider verifies your information properly, who the named prescriber is, and what follow-up is included.

  1. 01Complete a clinical assessment

    Medical history, current medication, BMI and any weight-related conditions. Around five minutes.

  2. 02Independent verification

    Weight-management medicines are classed as high-risk, so a prescriber must verify your information rather than rely on the form alone.

  3. 03Prescriber decision

    A named clinician decides whether treatment is appropriate. Some assessments end without treatment.

  4. 04Supply and follow-up

    Dispensed by a registered pharmacy, with scheduled reviews to manage dose changes and side effects.

Where to buy Saxenda in the UK

Three lawful routes, the same as for any weight-management injection. The NHS, where access is limited. A registered online pharmacy that assesses you before supplying. Or a high street pharmacy against a private prescription written after an assessment.

Each of those routes puts an assessment in front of the supply, and that is what separates them from everything else. A website that will sell you Saxenda without assessing you is operating outside the law, and the contents of what arrives cannot be verified.

You can check a UK pharmacy before you buy. Registered pharmacies appear on the General Pharmaceutical Council register, and registered online pharmacies display the MHRA distance selling logo as a link back to the regulator. A logo that is only a picture is not a registration.

How to get a Saxenda prescription

A clinical assessment first, covering medical history, current medication, height and weight, and any weight-related conditions. A prescriber then reviews it independently and decides whether Saxenda is appropriate.

Weight-management medicines are classed as high-risk, so the prescriber has to verify what you have reported rather than accept the form as submitted. That means a photograph, a video call, or contact with your GP. A provider that omits that step is not following the regulator's rules.

The answer can be no, and some assessments end without a prescription. That is the process working.

How to identify a licensed Saxenda supplier

Four checks. The pharmacy is on the GPhC register. It names its superintendent pharmacist. It shows the MHRA distance selling logo as a working link. And it will not supply without an assessment.

What should stop you is equally consistent: a price on the page, no assessment, no named prescriber, payment by bank transfer or cryptocurrency, or an offer of stock with no questions asked.

Sellers on social media, marketplaces and messaging apps are not licensed suppliers whatever their listing says. Falsified liraglutide has been found in UK supply chains and seized by the MHRA, and counterfeit packaging is usually better than people expect.

Can you buy Saxenda online?

Only from a registered pharmacy, and only after a clinical assessment and a prescription. Searching "saxenda buy online" returns plenty of sites willing to skip both; none of them is a lawful supplier, and what arrives from them cannot be verified for identity, strength or sterility.

A legitimate online pharmacy looks different in one specific way: it will not let you reach a checkout before a prescriber has decided. If you can add Saxenda to a basket, you are not on a pharmacy site.

What Saxenda reviews do and do not tell you

Searching "saxenda reviews" mostly returns individual accounts, and those are worth reading for what treatment feels like week to week: nausea after a dose increase, appetite changes, what people found manageable.

What reviews cannot tell you is whether Saxenda is appropriate for you. Response varies considerably between people, and a review is a sample of one with no information about the reader. The trial data on this page is the part that generalises; the reviews are the part that does not.

Saxenda price in the UK, and why no price is shown here

Saxenda is a daily injection rather than a weekly one, so cost is usually quoted per month of pens rather than per dose, and it changes as you titrate upward over the first weeks.

The reason no figure appears on this page is specific: prescription-only medicines cannot be advertised to the public in the UK, and a published price is advertising. You are quoted after assessment, once the dose is known. A site that shows you a price for Saxenda before assessing you is telling you it does not follow that rule.

What is worth comparing before you commit is what the price includes. Whether follow-up reviews are covered, whether dose increases cost more, whether prescriber contact is charged separately, and what happens if you stop.

Clinical evidence

What the trials showed

SCALE Obesity and Prediabetes

Mean weight reduction of 8.0% at 56 weeks

In 3,731 adults without diabetes with a BMI of 30 or above, or 27 or above with a weight-related condition, liraglutide 3.0 mg produced a mean reduction of 8.0% against 2.6% on placebo. 63.2% lost at least 5% of body weight, and 33.1% lost at least 10%.

Saxenda questions, answered

Where can I get Saxenda?

From a registered pharmacy after an assessment by a prescriber, whether that is through the NHS, a registered online pharmacy, or a high street pharmacy dispensing a private prescription. Any UK pharmacy can be checked on the GPhC register before you commit.

Can I order Saxenda online safely?

Yes, from a GPhC-registered pharmacy that assesses you first. A site that will sell Saxenda without an assessment is not a licensed supplier, and what it ships cannot be verified. Look for the MHRA distance selling logo as a working link and a named superintendent pharmacist.

Where can I buy Saxenda?

Only from a registered pharmacy, following a clinical assessment and a prescription from a named prescriber. Saxenda is prescription-only. Sites offering it without an assessment are supplying an unlicensed medicine.

How much does Saxenda cost?

Cost varies by provider and is discussed after assessment rather than advertised, because prescription-only medicines cannot be promoted to the public with pricing. Note that Saxenda is a daily injection, so the number of pens used per month differs from the weekly treatments.

Why is Saxenda injected daily when Mounjaro and Wegovy are weekly?

Liraglutide has a shorter duration of action than semaglutide or tirzepatide, so its effect does not persist across a week. Daily injection maintains the signal that the weekly treatments sustain with one dose. Daily dosing is the main practical difference people notice.

How much weight can you lose on Saxenda?

In the SCALE trial, adults taking liraglutide 3.0 mg lost an average of 8.0% of body weight over 56 weeks, compared with 2.6% on placebo. About a third lost at least 10%. Individual results vary considerably, and results depend on dietary and activity change alongside treatment.

Is Saxenda less effective than Mounjaro?

On average, yes. Trial data show smaller mean weight reduction for liraglutide than for tirzepatide or semaglutide at weight-management doses. It remains a licensed option, and the faster titration and daily dosing suit some people better than a larger weekly dose.

How long does Saxenda take to reach the full dose?

About five weeks. The dose rises by 0.6 mg each week, 0.6, 1.2, 1.8, 2.4, reaching the 3.0 mg maintenance dose from week five. That is much faster than the 16 to 20 weeks the weekly treatments take.

Can you buy Saxenda UK, and where from?

From a GPhC-registered pharmacy, after a prescriber has assessed you. Searching "buy Saxenda UK" also returns sites that will supply without an assessment; none of those is a lawful supplier, and what arrives cannot be verified for identity, strength or sterility.

Where to get Saxenda if the NHS route is not open to you?

A registered online pharmacy that assesses you first, or a high street pharmacy against a private prescription from a prescriber who has assessed you. Both have the same step in front of them, and the question of where to get Saxenda is really the question of who is taking responsibility for the decision.

What makes a Saxenda online pharmacy UK listing genuine?

Four checks. It appears on the General Pharmaceutical Council register. It names its superintendent pharmacist. It displays the MHRA distance selling logo as a working link rather than a picture. And it will not let you reach a checkout before a prescriber has decided. Any Saxenda online pharmacy UK result missing one of those is not what it claims.

Can you get Saxenda without prescription?

No. Saxenda is a prescription-only medicine, and searching "Saxenda without prescription" returns sellers operating outside the law rather than a shortcut nobody told you about. What arrives from them has unverified identity, strength and sterility; falsified pens have been found in UK supply chains and seized by the MHRA. There is no pharmacy, in any country, that may lawfully supply it without one.
