Head-to-Head Comparison
Wegovy and Saxenda both belong to the same class of medications known as GLP-1 receptor agonists. They work by mimicking a naturally occurring hormone that targets areas of the brain involved in appetite regulation, helping you feel fuller faster and longer.
However, Wegovy (Semaglutide) has a much longer half-life in the body compared to Saxenda (Liraglutide). This biological difference means Wegovy only needs to be injected once a week, whereas Saxenda requires a daily injection to maintain stable levels in your system.
Performance & Results
Semaglutide Trials
In comprehensive clinical studies, patients using the maximum maintenance dose of Wegovy (2.4mg) alongside lifestyle interventions achieved an average weight loss of around 15% over a 68-week period. Many participants exceeded this average, marking a significant leap forward in pharmacological weight management.
Liraglutide Trials
Patients taking the maximum dose of Saxenda (3.0mg) typically see an average weight loss of approximately 8% over a 56-week period. While this is highly beneficial for cardiovascular health and mobility, it falls short of the newer generation of treatments.
Cost & Accessibility
Budget plays a significant role in determining the best treatment plan. Saxenda offers a more gradual entry into GLP-1 treatments, with single pens available from approximately £49. This makes it an accessible option to trial the medication for a couple of weeks.
Wegovy is dispensed as a monthly supply (4 doses) starting at roughly £169. While the monthly outlay is higher initially, the increased efficacy often makes it more cost-effective when calculating the "price per percentage of weight lost."
Summary
Wegovy is widely regarded as the superior option for most patients due to its enhanced weight-loss capabilities and the convenience of a weekly injection schedule.
Saxenda remains a trusted, effective alternative for individuals who prefer a lower initial cost or who might experience severe side effects and prefer a daily medication that clears the system more rapidly if stopped.
