    How Mounjaro works

    What is Mounjaro (Tirzepatide)

    Mounjaro is a once-weekly injection containingTirzepatide, which is expected to be launched towards the end of 2023. It is currently licensed for the treatment of type-2 diabetes and may be prescribed off-label for weight loss at London Sliming clinic.


    Mounjaro is the brand name of the medication Tirzepatide. It mimics the action of one of your bodies naturally occurring incretin hormones – GLP-1 and GIP, which are released in your body after food intake. Bring a GLP-1 and GIP combination, it is the first of such type of medication in its class and works by regulating blood glucose levels.


    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. While Tirzepatide may be prescribed off label to help certain patients in their weight management, this will only be done as second line if the prescriber agrees that this would be the patient and other treatments are not suitable or have not been effective.
