Is Mounjaro (Tirzepatide) Approved For Weight Loss?

No, Mounjaro® is not FDA-approved for weight loss.  Currently, it is FDA-approved for the treatment of type 2 diabetes.  Mounjaro has demonstrated impressive weight loss in two recent studies and currently is being fast-tracked by the FDA for approval for weight loss.  One study found patients taking the highest dose of Mounjaro lost approximately 21% of their starting body weight after 72 weeks.  Another study of patients with type 2 diabetes taking Mounjaro for weight loss showed an average of 15.7% weight loss at 72 weeks.  At this time, using Mounjaro for weight loss is considered off-label use, but this will likely change in the near future.  It should be noted that medications for weight loss may be indicated for individuals with a body mass index (BMI) of 27+ kg/m2 with a weight related medication condition such as high blood pressure or diabetes or a BMI of 30+ kg/m2.
