Who is eligible for Mounjaro?

Mounjaro can be considered for adults living with obesity as part of a structured plan that includes a reduced‑calorie diet and increased physical activity.

When Mounjaro may be considered

Body‑mass criteria:

A BMI of 30 kg/m² or above.

Body‑mass criteria:

A BMI between 27 and 30 kg/m² (overweight) plus at least one weight‑related health condition, such as high blood pressure, raised cholesterol, or type 2 diabetes.

Mounjaro is intended to support meaningful, longer‑term changes alongside lifestyle measures, with the goal of improving health outcomes for people at higher risk due to excess weight.

If you meet these criteria, a clinician may decide Mounjaro is appropriate for you after a full medical assessment.

Who should not take Mounjaro?

Mounjaro will be ruled out in certain situations, including if you:

Are pregnant, breastfeeding or hoping to become pregnant soon
Have previously reacted badly to semaglutide or any component of Mounjaro.
Have a personal or family history of specific rare thyroid tumours (such as medullary thyroid carcinoma) or Multiple Endocrine Neoplasia syndrome type 2 (MEN2).
Live with particular serious conditions affecting the gut or pancreas; these are reviewed carefully before any medicated weight management is considered.

What is Mounjaro?

Mounjaro is a prescription medicine used as part of medicated weight management for certain adults living with obesity or overweight and related health conditions.

It contains tirzepatide, which acts on two gut‑hormone pathways (GIP and GLP‑1) involved in appetite, fullness and blood‑sugar control, supporting healthy weight management alongside diet and activity changes.¹ Its long half‑life allows once‑weekly dosing while maintaining these effects between doses.¹

Mounjaro is only considered where a qualified prescriber believes it is clinically appropriate after reviewing your medical history and current medicines.

Any decision to start or continue treatment is made by a qualified prescriber after medical review.

How does Mounjaro work?

Mounjaro is used as part of medicated weight management to act on two hormone pathways, GIP and GLP‑1, that help regulate appetite, blood‑sugar control and how the body stores and uses fat.¹

Reduces appetite:

Mounjaro works on areas of the brain that influence hunger, so you can feel satisfied with less food as part of healthy weight management.

Supports insulin sensitivity:

It helps your body use insulin more effectively, which can keep blood‑sugar levels steadier.

Affects fat processing:

By acting on gut‑hormone signals, it plays a role in how your body handles fats and sugars, supporting longer‑term weight management.

Long‑acting effect:

Mounjaro stays active in the body between doses, allowing for a consistent approach to medicated weight management alongside lifestyle changes.

Research shows this dual ‘twincretin’ action is linked with reductions in body fat mass, BMI and waist circumference, alongside improvements in glycaemic control. ¹ ²

How effective is Mounjaro for weight management?

Clinical studies and a large systematic review show that tirzepatide can support substantial weight change when used alongside nutrition and activity changes as part of medicated weight management.² ³

In phase 3 trials, higher tirzepatide doses led to average body‑weight reductions of roughly 15–23%, compared with about 2–3% with placebo. ³

Across 12 randomised trials involving 11,758 people, tirzepatide reduced body weight, BMI and waist circumference more than placebo, GLP‑1 receptor agonists and insulin. ²

Many people notice changes in appetite, eating patterns and health markers over time, but Mounjaro results vary and some individuals may respond less than others.

Your clinician will review your progress regularly and may recommend adjusting, pausing or stopping treatment if it is not providing enough benefit for your healthy weight management plan.

It’s more than just weight loss.
