Is Mounjaro better than Wegovy? Which is more effective?


Is Mounjaro better than Wegovy? Which is more effective? 


Recently, two notable medications have surfaced in the field of diabetes management and weight loss in the UK: Mounjaro (Tirzepatide) and Wegovy (Semaglutide). Though both are classified as GLP-1 receptor agonists, they exhibit unique characteristics, mechanisms of action, and suitability for different patients. Wegovy (Semaglutide) and Mounjaro (Tirzepatide) are brand-name injections; while Wegovy is approved and prescribed for weight loss, Mounjaro was initially approved for treating type 2 diabetes but has since been officially authorised for weight loss and management by NICE in adults aged 18 and over in the UK, where it is prescribed specifically for weight loss purposes. 

If you’re considering Wegovy or Mounjaro or want to learn more about weight loss injections, visit our Mounjaro Blog Page and Wegovy Blog Page for detailed information.

Additionally, you can contact SemaPen, part of the Phoenix Health bariatric group, a reputable NHS weight loss provider in the UK, for personalised advice to help you select the most suitable medication for you. 

Mounjaro vs Wegovy: Which is more effective?


While there has been no direct comparison between Wegovy and Mounjaro in clinical trials specifically for weight loss, their effects on individuals with type 2 diabetes have been evaluated in a review of trials. The review states that Mounjaro, when administered at its highest dosage of 15 milligrams (mg) weekly, resulted in more significant weight reduction compared to Wegovy, which is given at a peak dose of 2.4 mg weekly. 

Furthermore, an additional review of trials analysed these medications’ impact on non-diabetic individuals found that patients taking Mounjaro (administered in dosages of either 10 mg or 15 mg weekly) showed greater weight loss than patients taking Wegovy (administered at 2.4 mg weekly). 

It’s crucial to acknowledge that the findings from these trials and analyses might not directly correlate to your unique health circumstances. It’s recommended to consult with your healthcare provider to ascertain the suitability of Wegovy or Mounjaro for your specific needs. 

Both medications have been shown to significantly reduce weight and enhance blood sugar levels in individuals, irrespective of their diabetic status. Nonetheless, it’s essential to bear in mind that individual results may vary depending on factors such as body mass index (BMI), pre-existing health conditions, and commitment to the weight loss regimen.
