Mounjaro (Tirzepatide) in Ireland: 2025 Guide to Access, Costs & Availability

1. Introduction 

If you are managing Type 2 diabetes or exploring medical options for weight loss, you have likely heard of Mounjaro. Known scientifically as Tirzepatide, this medication represents the newest generation of treatments affecting blood sugar and appetite control. 

With the ongoing shortages of other medications like Semaglutide, many patients in Ireland are asking about Tirzepatide as an alternative. 

In this guide, we break down exactly how it works, how much it costs in Ireland as of late 2025, and how the consultation process works with Eirdoc. 

1. What is Tirzepatide and How Does it Work? 

Tirzepatide is unique because it mimics two naturally occurring hormones: GIP and GLP-1. 

• The Dual Action: While older medications like Semaglutide only mimic one hormone (GLP-1), Tirzepatide’s dual mechanism targets two distinct receptors. 

• The Result: This helps stimulate insulin release when blood sugar is high, delays gastric emptying (slowing down digestion), and signals to the brain that you are “full,” which significantly reduces appetite. 

Tirzepatide vs. Semaglutide: What is the difference? The main difference is the active ingredient and the licensing. 

• Semaglutide: Licensed primarily for Type 2 Diabetes. 

• Tirzepatide: Licensed in Ireland for both Type 2 Diabetes and Weight Management (for those with a BMI of 30+, or 27+ with comorbidities). 

• Semaglutide and Liraglutide are the potent options for weight losss, both are GLP-1 recepter agonists, but differ in dosing frequency, power of active ingredient, and weight loss efficiency.  

1. Is Mounjaro Available in Ireland? 

Yes, Tirzepatide is authorized for use in Ireland. However, like many GLP-1 medications, stock levels can be intermittent. 

Due to high global demand, some pharmacies may face supply shortages. In these cases, pharmacies often prioritize existing patients with Type 2 diabetes. If you are starting a new treatment plan, it is important to check availability with your local pharmacy first. 

Reimbursement Status: Currently, Tirzepatide is generally not covered by the Medical Card or Drugs Payment Scheme (DPS) for weight loss. Most patients access it via private prescription, meaning you will pay the full cost of the medication at the pharmacy. 

1. How Effective Is It? 

Clinical trials (such as the SURMOUNT program) have demonstrated high efficacy for Tirzepatide. 

• For Weight Loss: Studies suggest it can help suitable patients lose a significant percentage of their body weight (up to 20% in some trials) when combined with diet and exercise. 

• For Diabetes: It is highly effective at improving insulin sensitivity and stabilizing blood sugar levels. 

1. How to Access a Prescription in Ireland 

Tirzepatide is a Prescription Only Medicine (POM). You cannot buy it over the counter. You must have a consultation with a registered doctor—either your local GP, an endocrinologist, or a reputable online doctor service like Eirdoc. 

The Eirdoc Process: At Eirdoc, we do not “sell” medication. We provide a comprehensive Weight Management Consultation. 

1. Assessment: You complete a detailed medical questionnaire regarding your health, BMI, and medical history. 

1. Review: One of our Irish-registered GPs reviews your case to see if a GLP-1 treatment is clinically safe and appropriate for you. 

1. Prescription: If suitable, a prescription is sent directly to your chosen pharmacy via Healthmail. 

1. Medical Checklist: Is it safe for you? 

During your consultation, your doctor will screen for specific contraindications. You may not be eligible for Tirzepatide if: 

• You or your family have a history of Thyroid Cancer or MEN 2 syndrome. 

• You have a history of Pancreatitis. 

• You have severe Kidney or Gallbladder disease. 

• You are pregnant or breastfeeding (“best fed” was a typo in your original text). 

• You have a history of severe allergic reactions.
