Cost is the question we hear most often. Before side effects, before eligibility, before how it works - people want to know what this is actually going to cost them month to month. That is completely fair, and we believe in being upfront about it.

This guide breaks down every component of the cost of Mounjaro treatment in Ireland in 2026. There are no hidden charges in what follows. By the end, you will have a realistic picture of what to budget, where the money goes, and how to reduce the overall cost through tax relief.

Before we get into the numbers, it is worth understanding how you access Mounjaro in Ireland. If you are not sure whether you meet the clinical criteria, our guide to Mounjaro eligibility in Ireland explains the BMI thresholds and health conditions that doctors assess.

How Mounjaro Costs Are Structured in Ireland

Unlike some countries where medication and consultation are bundled into a single fee, the Irish system separates them. When you use a service like Bua Health, you are paying for two distinct things:

• Clinical support - the doctor consultations, prescribing, monitoring, and dietitian access
• Medication - the Mounjaro pens themselves, paid directly to the pharmacy

This split exists because Irish regulations require that prescription medication is dispensed by a licensed pharmacy, not by the prescribing service. It is not a quirk of any one provider - it is how the system works.

The Two Cost Components

1. Clinical Support Fee

At Bua Health, the clinical support fee is €50 per month. This covers:

• Your initial medical assessment by an IMC-registered doctor
• Ongoing monthly GP reviews and dose management
• Prescription generation and pharmacy coordination
• Access to specialist dietitian support
• Unlimited messaging with the clinical team

This is a monthly opt-in. There are no contracts, no automatic renewals, and no lock-in. If you are assessed and found to be clinically ineligible, you receive a full refund.

How this compares to the traditional GP route: If you go through your local GP, each consultation typically costs €50-70 per visit. During the first few months of treatment, you will likely need monthly visits for dose adjustments, blood pressure checks, and side-effect management. That is €50-70 per appointment, without dietitian access, without messaging support between visits, and without the specialist weight management oversight that clinical guidelines recommend alongside these medications. Over six months of titration, GP visits alone could run to €300-420, and that is before you factor in additional visits if side effects need managing or if you want dietary guidance - which would mean a separate referral to a private dietitian at €60-100 per session.

With Bua, the €50 per month covers all of that in one place. It is designed specifically for medical weight management, which means the doctors, the dietitian support, and the ongoing monitoring are built into one fee rather than being pieced together across multiple providers and appointments.

2. Medication Cost (Paid to Pharmacy)

Mounjaro is priced per pen, and the cost increases as your dose increases during titration. Eli Lilly increased the list price in September 2025, so figures from older articles are likely out of date. Pharmacies also set their own dispensing margins, which is why the same dose can cost noticeably different amounts depending on where you go.

Across Irish pharmacies, Mounjaro medication typically ranges from around €200 per month at the 2.5mg starting dose up to €600 per month at the highest strengths. Where exactly you fall in that range depends on your prescribed dose and which pharmacy you use.

Prices are indicative and vary by pharmacy. The 10mg, 12.5mg, and 15mg doses may not yet be widely available in all Irish pharmacies. Always confirm the current price with your pharmacy before ordering.

A few things worth noting. Not everyone reaches the highest doses. Your doctor will find the dose that works for you, which may be lower than the maximum. The starting months are at the lower end of the cost range. And prices across the market may shift as supply stabilises and competition increases.

Total Monthly Cost: What to Actually Budget

Combining the two components gives you a realistic monthly picture.

These figures are before tax relief, which we cover below. Patients using Bua's partner pharmacy will typically be at the lower end of these ranges thanks to our negotiated fixed pricing.

Can You Get Mounjaro on the Medical Card or Drugs Payment Scheme?

As of mid-2026, Mounjaro is not reimbursed under the HSE's General Medical Services (GMS) scheme or the Drugs Payment Scheme (DPS) for weight management in Ireland.

The National Centre for Pharmacoeconomics (NCPE) is conducting a health technology assessment for Mounjaro. A decision on reimbursement is expected during 2026, and Mounjaro is considered by some analysts to be a stronger candidate than Wegovy given its different active ingredient and the greater average weight loss shown in clinical trials.

For now, patients pay privately for Mounjaro when used for weight management. The one exception is Saxenda (liraglutide), which is currently the only weight loss medication reimbursed under State schemes, and only under a strict Managed Access Protocol for patients with a BMI of 35 or above who also have prediabetes and elevated cardiovascular risk.

If HSE coverage is an important factor in your decision, it may be worth discussing the current options with your doctor. For a broader look at what is and is not covered, see our guide to what weight loss injections are available in Ireland.

Tax Relief: How to Get 20% Back

This is the single most overlooked way to reduce the cost of Mounjaro treatment in Ireland. Many patients do not realise they can claim tax relief on both their consultation fees and their medication costs.

Under the Irish tax system, medical expenses qualify for tax relief at the standard rate of 20%. This applies to:

• Fees paid for GP or specialist consultations (including telehealth consultations)
• The cost of prescription medication dispensed by a registered pharmacy
• Costs incurred outside the Republic of Ireland, provided the prescriber holds an equivalent registration (e.g., GMC in the UK)

Worked Example

That is nearly €1,000 back in your pocket. Over two years of treatment, the saving approaches €2,000. At higher doses, the annual tax relief can exceed €1,200.

To claim, you submit a Med 1 form (or do it online through Revenue's myAccount portal) with itemised receipts from your pharmacy and your consultation provider. Keep every receipt.

How Mounjaro Compares on Cost

If you are weighing up different treatment options, cost is one factor alongside clinical suitability. The table below gives a rough monthly comparison at typical doses in Ireland.

Wegovy is generally the more affordable option at standard maintenance doses. However, Mounjaro has shown greater average weight loss in direct comparison trials - the SURMOUNT-5 trial showed 20.2% average weight loss with tirzepatide versus 13.7% with semaglutide over 72 weeks. This is ultimately a clinical decision for you and your doctor, not a purely financial one.

What You Can Do to Manage Costs

A few practical strategies:

Use Bua's partner pharmacy network. We have negotiated the lowest fixed pricing available to give our patients predictable, competitive rates at every dose level. This removes the guesswork of comparing pharmacies and means you always know exactly what your medication will cost each month.

Claim your tax relief every year. As shown above, this can save close to €1,000 per year. Many patients do not claim because they do not realise they are eligible. You are.

Plan for the long term. Mounjaro is most effective as part of an ongoing treatment plan. Understanding the monthly cost upfront and building it into your budget helps avoid surprises. Some patients find it helpful to think of it as a monthly health investment comparable to private health insurance or other ongoing health commitments.

Ask about dose optimisation. Not everyone needs the highest dose. Your doctor will find the dose where you achieve good clinical results with manageable side effects. A lower maintenance dose means a lower monthly medication cost. To understand more about how dosing works, see our guide to Mounjaro side effects and what to expect.

What This Means for You

Mounjaro treatment in Ireland is a private cost for most patients in 2026. Medication ranges from €200 to €600 per month depending on dose, with Bua's clinical support at €50 per month on top of that. With tax relief claimed, the effective annual cost reduces by approximately 20%.

If cost has been holding you back from exploring treatment, it is worth running the numbers with your own situation in mind. The tax relief, in particular, is significant and often overlooked - and Bua's negotiated partner pharmacy pricing is designed to keep the medication cost as low as possible.

If you would like to find out whether Mounjaro might be suitable for you, you can check your eligibility online in under 4 minutes. Our clinical partners at MedicOnline will review your assessment, and if treatment is not appropriate, you receive a full refund of your programme fee.
