Ozempic vs Wegovy vs Mounjaro: What’s the Difference?

What Do These Medicines Have in Common?

All three medicines:

Are injectable medications Work on hormones that regulate appetite Help reduce hunger and calorie intake Are used under medical supervision Are not cosmetic weight loss solutions

However, they differ significantly in composition, approval, and effectiveness.

Ozempic

Active ingredient: Semaglutide

Originally approved for: Type 2 diabetes

Key Points

Used once weekly as an injection Causes appetite reduction and early satiety Weight loss observed as a secondary benefit In India, use for weight loss is off-label

Ozempic became popular after doctors noticed consistent weight loss in diabetic patients.

Wegovy

Active ingredient: Semaglutide (higher dose than Ozempic)

Approved for: Chronic weight management (in some countries)

Key Points

Specifically designed for obesity and weight loss Higher dose of semaglutide compared to Ozempic Produces greater average weight loss Not widely available in India yet

Wegovy is essentially a weight-loss-focused version of semaglutide.

Mounjaro

Active ingredient: Tirzepatide

Mechanism: Dual action (GLP-1 + GIP receptor agonist)

Key Points

Mounjaro is currently considered one of the most powerful medical weight loss options, but also requires careful monitoring.
