How Saxenda works

Saxenda contains liraglutide, an older-generation GLP-1 receptor agonist. Like Wegovy and Mounjaro, it mimics the GLP-1 gut hormone to reduce appetite, slow gastric emptying, and regulate blood sugar. It was one of the first GLP-1 medications to be licensed specifically for weight management in the UK.

The main practical difference from newer options is that Saxenda requires a daily injection rather than a weekly one, and it produces less weight loss on average (~8% vs 20%+ for Mounjaro and Wegovy). For this reason, Saxenda is increasingly being replaced by the newer weekly medications, though it remains a valid option for people who prefer it or who don't tolerate the alternatives.

Dosing schedule

Saxenda is titrated weekly (faster than the monthly escalation of Mounjaro and Wegovy):

If you experience significant side effects at a dose, your prescriber may keep you at a lower dose for longer before increasing.

Who is Saxenda for?

Licensed for: Weight management in adults with BMI ≥30, or BMI ≥27 with at least one weight-related comorbidity.1

NHS: Available through Tier 3 specialist weight management services.

Common side effects

Serious risks include pancreatitis (~1 in 100) and gallbladder disease.1

Key clinical trials

SCALE programme: The pivotal trial showed liraglutide 3.0mg produced an average weight loss of approximately 8% of body weight over 56 weeks, with 63% of participants losing at least 5%.2

Cost in the UK

Private prescriptions for Saxenda typically cost £150–£230 per month. This is broadly comparable to Mounjaro and cheaper than Wegovy, though the lower average weight loss means the cost-per-outcome may be less favourable.
