When comparing Wegovy vs Mounjaro, many people are trying to decide which weight loss injection offers the best balance of results, safety, and value in the UK. Both are prescription-only treatments used under medical supervision, but they work differently and can suit different patients.
This guide explains the differences clearly so you can make an informed choice.
How Wegovy and Mounjaro Work
Wegovy contains semaglutide and works by targeting one hormone that regulates appetite and fullness. It helps reduce hunger, slow digestion, and support gradual weight loss.
Mounjaro contains tirzepatide and targets two appetite-regulating hormones, which often leads to stronger appetite suppression and greater weight loss for suitable patients.
This difference in mechanism is the biggest distinction between the two treatments.
Weight Loss Results: Wegovy vs Mounjaro
Clinical studies and real-world outcomes show clear differences in average weight loss:
• Wegovy: around 10%–15% body weight loss
• Mounjaro: often 15%–25% body weight loss
While individual results vary, Mounjaro generally delivers higher average weight loss, while Wegovy provides steady and predictable results.
Side Effects Compared
Both injections share similar side effects, particularly during dose increases:
• Nausea
• Reduced appetite
• Mild stomach discomfort
• Fatigue
Wegovy is often described as slightly gentler, especially at lower doses. Mounjaro’s stronger appetite suppression can feel more intense early on for some patients.
Gradual dose escalation avoids most issues for both treatments.
Dosing and Ease of Use
Both Wegovy and Mounjaro:
• Are taken once weekly
• Use pre-filled injection pens
• Can be self-administered at home
• Follow a step-up dosing schedule
From a practical point of view, ease of use is very similar.
