What is Mounjaro (Tirzepatide)?

Mounjaro is a prescription-only once-weekly injection with the active ingredient Tirzepatide. It is licensed in the UK for weight management (weight loss and weight maintenance) and the treatment of Type 2 diabetes. You can order Mounjaro online at the London Slimming Clinic.

Mounjaro is the brand name of the medication Tirzepatide. It mimics the action of your body's naturally occurring incretin hormones, GLP-1 and GIP, released after food intake. With a combination of GLP-1 and GIP receptors, it is the first medication in its class that regulates hunger, satiety, and blood glucose levels.

Mounjaro can be taken for weight loss by those who have a BMI of above 30 or a BMI of 27-30 with at least one weight-related comorbidity (a condition caused by being overweight or would improve by weight loss), such as:

  • High cholesterol
  • Type 2 diabetes
  • Pre-diabetes
  • High blood pressure
  • Obstructive sleep apnoea
  • Osteo-arthritis

In addition to controlling blood glucose levels, clinical trials of Mounjaro have shown a significant weight loss in patients, greater than any other GLP-1 currently licensed for weight loss.

Mounjaro and Ozempic are both different medications with different active ingredients. Mounjaro has an active ingredient, Tirzepatide, while Ozempic contains Semaglutide as the active ingredient. Ozempic is manufactured by Novo Nordisk, while Mounjaro is manufactured by Eli Lilly.

Although both medications are GLP-1 receptor agonists, Mounjaro is also a GIP mimetic. Mounjaro and Ozempic are both licensed for type 2 diabetes. Ozempic was used off-label for weight loss. Mounjaro is now also approved for weight loss in the UK.

Are Mounjaro and Wegovy the Same?

Mounjaro and Wegovy are two different medications with distinct active ingredients. Mounjaro has been recently authorised by the MHRA to be used as a weight loss medication.

Wegovy has the active ingredient Semaglutide and is manufactured by Novo Nordisk. Mounjaro has the active ingredient Tirzeptide and is manufactured by Eli Lilly.

Switching to Mounjaro from Wegovy

If you are currently taking Wegovy and wish to switch to Mounjaro, the current advice is as follows:

  1. If you’re on a low dose of Wegovy (up to 1mg), you must stop treatment for 2 weeks before commencing treatment of Mounjaro
  2. If you’re on a higher dose of Wegovy (more than 1mg) you must stop treatment for 4 weeks before commencing treatment of Mounjaro

You should not take both medications at the same time as they work in very similar ways and could produce dangerous side effects if taken together. Always speak to your doctor before switching medications.
