How does liraglutide compare to semaglutide?

Liraglutide requires daily injection vs semaglutide's weekly injection. Liraglutide achieves ~8% weight loss (SCALE) vs semaglutide's ~15% (STEP 1). Semaglutide has largely superseded liraglutide for weight management, but liraglutide remains a viable option for patients who cannot tolerate semaglutide or prefer a lower-intensity medication.

What is the difference between Victoza and Saxenda?

Both contain liraglutide by Novo Nordisk. Victoza (max 1.8 mg/day) is for type 2 diabetes. Saxenda (max 3.0 mg/day) is for chronic weight management. The formulations are not interchangeable.

Liraglutide is a first-generation GLP-1 receptor agonist used for weight management (Saxenda) and type 2 diabetes (Victoza). Developed by Novo Nordisk, it requires daily injection and has shown cardiovascular risk reduction benefits.

What is the recommended dose range for Liraglutide?

The research dose range is Saxenda: 0.6-3.0 mg/day; Victoza: 0.6-1.8 mg/day, administered via Subcutaneous, Once daily.
