Saxenda vs Wegovy: Which Is More Effective for Weight Loss?

Q: What are Saxenda and Wegovy?

Saxenda and Wegovy are FDA-approved injectable medications containing GLP-1 receptor agonists, used for weight loss by increasing satiety and reducing appetite.

Introduction

Medications like Saxenda and Wegovy have transformed weight management by offering FDA-approved injectable options. While both are GLP-1 receptor agonists made by Novo Nordisk, they differ in dosing, effectiveness, and convenience.

What Are Saxenda and Wegovy?

Saxenda (Liraglutide)

Saxenda contains liraglutide, approved in 2014 for weight loss. It is a daily injectable that increases satiety by mimicking a hormone called GLP-1, helping reduce appetite alongside diet and exercise.

Wegovy (Semaglutide)

Wegovy, approved in 2021, contains semaglutide. It is administered weekly, lasts longer in the body, and has shown to produce more significant weight loss than Saxenda when combined with lifestyle changes.

How Do They Work?

Both medications are GLP-1 receptor agonists that stimulate hormones to promote fullness, decrease hunger, and lower blood sugar. They mimic the natural GLP-1 hormone, but their effects last longer, enabling less frequent dosing.

Comparative Effectiveness

Clinical trials show Wegovy leads to approximately 15.8% weight loss over 68 weeks, whereas Saxenda results in about 6.4%. Patients on Wegovy tend to lose roughly 9.4% more weight than those on Saxenda.

Wegovy: About 14.9% weight loss (study with 1,961 participants)
Saxenda: 5-10.6% weight loss (study with 3,731 participants)

Differences in Dosing and Administration

Frequency

Saxenda is a daily injection, starting at 0.6 mg and increasing weekly to 3 mg. Wegovy is weekly, starting at 0.25 mg, increasing over weeks to 2.4 mg.

Pens and Dosing Devices

Saxenda uses a multi-dose pen; Wegovy uses a new single-dose pen weekly. The dosing schedules differ, requiring tailored medical guidance.

Side Effects and Safety

Common Side Effects

Both drugs may cause gastrointestinal symptoms like nausea, diarrhea, and vomiting, which usually improve over time.

Serious Risks

Both carry FDA warnings for thyroid cancer risk, and serious side effects may include pancreatitis, gallbladder issues, kidney problems, and rare suicidal thoughts.

Patients should discuss personal health history with their provider before starting.

Cost and Insurance Coverage

The retail price for a month’s supply of either medication is approximately $1,430. Insurance coverage varies; prior authorization may be needed, and savings programs are available through manufacturers and discount sites.

Who Should Avoid These Medications?

Individuals with personal or family history of thyroid cancer, pancreatitis, or other specific health conditions should consult a healthcare provider to determine suitability.

Alternatives and Additional Options

Other medications like Zepbound (tirzepatide), Qsymia, Contrave, and Orlistat are available. Lifestyle changes, including diet and exercise, remain foundational.

Choosing the Right Medication

Wegovy may be preferred for those seeking less frequent injections and potentially greater weight loss, but individual factors like side effects, cost, and medical history should guide choice. Consult your healthcare provider.
