Saxenda is one of the most established prescription weight-loss injections available in the UK, and it remains a popular option for people exploring medically supervised weight management. Because it is often searched for alongside newer treatments, patients frequently have questions about how it is taken, what dose to expect, how it compares to Ozempic, Wegovy and Mounjaro, and where it can be obtained safely. This guide answers those questions in one place.
What Is Saxenda?
Saxenda is the brand name for liraglutide, a GLP-1 receptor agonist licensed in the UK for chronic weight management in adults with obesity, or with overweight alongside a weight-related health condition. It works by mimicking a naturally occurring gut hormone that helps regulate appetite, slows gastric emptying, and increases feelings of fullness after eating.
Saxenda Injection or Saxenda Tablets?
A common question is whether Saxenda is available as a tablet. At present, Saxenda is only licensed as a subcutaneous injection, administered once daily using a pre-filled pen device with a fine needle, typically injected into the abdomen, thigh or upper arm. There is currently no licensed oral (tablet) version of liraglutide for weight management in the UK. Patients who prefer to avoid daily injections sometimes ask their prescriber about weekly alternatives such as Wegovy or Mounjaro, discussed below.
Saxenda Dosage: How the Dose Escalation Works
Saxenda is started at a low dose and gradually increased to reduce the likelihood of gastrointestinal side effects. The standard dose escalation schedule is:
- Week 1: 0.6 mg once daily
- Week 2: 1.2 mg once daily
- Week 3: 1.8 mg once daily
- Week 4: 2.4 mg once daily
- Week 5 onwards: 3.0 mg once daily (maintenance dose)
Your prescriber may adjust this schedule if side effects occur, and not everyone will need to reach the full 3.0 mg dose to see meaningful results. Saxenda is injected at the same time each day, with or without food.
Saxenda vs Ozempic
Saxenda (liraglutide) and Ozempic (semaglutide) are both GLP-1 receptor agonists, but they are different molecules with different dosing schedules. Saxenda is injected once daily, while Ozempic is injected once weekly. Ozempic is licensed in the UK for type 2 diabetes management rather than weight loss specifically, whereas Saxenda holds a dedicated weight management licence. Clinical trial data generally suggests semaglutide produces greater average weight loss than liraglutide, though individual results vary considerably.
Saxenda vs Wegovy
Wegovy is also semaglutide, at a higher weekly dose (up to 2.4 mg) than Ozempic, and is specifically licensed for weight management, making it a closer comparison to Saxenda in terms of intended use. The main practical difference is dosing frequency: Saxenda requires a daily injection, while Wegovy is a once-weekly injection. In head-to-head style comparisons of trial data, Wegovy has generally been associated with greater average weight loss than Saxenda, but some patients tolerate liraglutide’s more gradual daily dosing better.
Saxenda vs Mounjaro
Mounjaro (tirzepatide) works on both the GIP and GLP-1 receptors, whereas Saxenda works on the GLP-1 receptor alone. Mounjaro is injected once weekly. Trial data for tirzepatide has generally shown higher average weight loss compared with liraglutide-based treatments like Saxenda, though Mounjaro is a newer medication and not everyone is a suitable candidate for it. The right choice between the two depends on individual health history, tolerability and clinical assessment.
Saxenda Reviews: What Do Patients Say?
Patient experiences with Saxenda vary, as with any weight-loss treatment. Many people report steady, gradual weight loss over several months, particularly when combined with dietary changes and increased activity. The daily injection routine is sometimes cited as a drawback compared with weekly alternatives, while others prefer the smaller, more frequent dose adjustments it allows. As with all GLP-1 medications, early weeks can involve nausea or digestive changes that tend to ease as the body adjusts to each new dose level. In the pivotal SCALE trial, participants taking liraglutide 3.0 mg lost an average of around 8% of their body weight over 56 weeks, compared with roughly 2.6% in the placebo group.
Can I Buy Saxenda Online?
Saxenda is a prescription-only medication in the UK. It cannot be legally purchased online without a valid prescription issued after an appropriate clinical assessment. Be cautious of websites offering Saxenda without any medical consultation, as these are not operating within UK regulations and may not supply genuine medication. The safe way to access Saxenda online is through a registered UK pharmacy and a regulated prescribing service, where a clinician reviews your medical history and suitability before any prescription is issued.
Side Effects
The most commonly reported side effects of Saxenda include nausea, vomiting, diarrhoea, constipation, and injection site reactions. These are usually most noticeable during dose increases and tend to lessen over time. Rare but more serious side effects can occur, which is why ongoing clinical supervision throughout treatment is important.
