What Is Mounjaro (Tirzepatide) Used For?

Mounjaro® is an FDA-approved medication used to treat type 2 diabetes.  It is a dual GLP-1/GIP* receptor agonist which acts to stimulate the release of insulin by the pancreas which lowers blood sugar levels.  It can also improve insulin sensitivity and promote weight loss.  At this time, Mounjaro is not FDA-approved for weight loss, but it is anticipated to be FDA-approved for this indication in the near future.  A study published in the New England Journal of Medicine found in combination with healthy nutrition and increased physical activity, people taking the highest dose of Mounjaro lost on average 21% of their starting body weight after 72 weeks on the medication.  Additionally, over 80% of people on the highest dose were able to lose at least 10% of their total body weight.  Doctors may prescribe Mounjaro to patients without diabetes ( considered off-label use) for the purpose of weight loss in combination with healthy nutrition and increased physical activity so long as it is medically appropriate.
