Who Qualifies for Mounjaro in Ireland?
An overview of the clinical criteria, safety checks, and medical assessment process doctors use to decide who is eligible for Mounjaro® (tirzepatide) in Ireland.
Read
Mounjaro (tirzepatide) is a once-weekly injectable prescription medicine used for weight loss in adults who are overweight or have obesity, and to help manage blood sugar levels in adults with type 2 diabetes. In order to maximise benefits, Mounjaro should be used alongside a plan for diet and exercise. Generally, treatment can be suitable for patients with a BMI of 30 or above, or a BMI of 27 or above if you have a weight-related health condition such as high blood pressure.
Mounjaro is a prescription medicine (active ingredient: tirzepatide). It is prescribed for adults to treat type 2 diabetes and to help with weight management and weight control.
This medicine is designed to work alongside lifestyle modifications. To achieve the best results, it should be part of a plan that includes a reduced-calorie diet and regular physical activity. In a major clinical trial, participants with obesity or who were overweight experienced an average weight reduction of up to 20.9% over 72 weeks.
It is intended to be used as part of a broader management plan that includes diet and exercise. Your GP or specialist will have prescribed this to you based on your specific health needs. At Bua, our partner clinicians work with patients to create bespoke plans which encompass lifestyle adjustments, and where suitable, medication treatment.
Eligibility is primarily determined by your Body Mass Index (BMI), which is a measure of your weight relative to your height:
BMI of 30kg/m² or higher: You are generally eligible for treatment based on your weight alone.
BMI of 27kg/m² to 29.9kg/m²: You can't usually access the medication based on weight alone in this range. You'll need to have at least one weight-related health condition, such as:
A doctor will check your health profile to ensure there are no medical reasons that prevent you from taking it. For example, generally, you won't be suitable for Mounjaro if you have:
Clinical studies have shown patients can lose up to 22% of their weight by following a combination of weekly Mounjaro injections over an extended period and consistent lifestyle changes.
With our personalised plan, you could reach 80 kg in 10 months. That's a weight loss of 20 kg.
This projection is based on the average results from large-scale clinical trials and is for informational purposes only.
Clinical trials have observed the following changes for some patients:
Note: Individual results vary. These outcomes are based on clinical trial data and should be discussed with your healthcare provider.
Before you use Mounjaro for the first time, your healthcare provider should show you how to inject it. Always read the full "Instructions for Use" leaflet provided with your medicine.
Important Note: Every time you inject, select a new location that is at least a finger's width apart from the previous site. Rotating your injection sites is crucial for preventing the development of persistent, hard lumps (fatty nodules), which can form and reduce how well your medication works.
Like all medicines, Mounjaro can cause side effects, although not everybody will experience them. It's important to be aware of what to look for.
Very Common Side Effects (may affect more than 1 in 10 people): Nausea, diarrhoea, constipation, and vomiting. These are often not severe and tend to decrease over time. Low blood sugar (hypoglycaemia) is very common when Mounjaro is used with other diabetes medicines that contain a sulphonylurea or insulin. Your doctor may need to adjust the dose of your other medicines to reduce this risk. Signs of low blood sugar include headache, drowsiness, weakness, dizziness, feeling hungry, confusion, irritability, fast heartbeat, and sweating.
