Mounjaro is a weekly weight loss injection that contains the active ingredient tirzepatide. Tirzepatide works by activating two receptors (GLP-1 and GIP) to increase the level of hormones in the body, helping you to feel fuller for longer after a meal.

Mounjaro should be taken just once a week alongside a healthy diet and exercise. It has been proven to help people lose around 22.5%* of their initial body weight by week 72 of treatment, at a maximum dose of 15 mg.

To be eligible for Mounjaro for weight loss, you must have a body mass index (BMI) of 30 kg/m2 or more (obese), or of at least 27 kg/m2 (overweight) and have a risk factor or a health condition that is affected by weight.
