If you have searched "is Mounjaro available in Ireland," you probably want to know whether you can actually get it, what it costs, whether the supply is reliable, and how to make sure you are getting a genuine product. These are the right questions - and this guide answers all of them honestly.
What Is Mounjaro and Why Is There So Much Interest?
Mounjaro is the brand name for tirzepatide, a once-weekly injectable medication manufactured by Eli Lilly. Unlike most GLP-1 weight loss medications - which mimic one gut hormone - tirzepatide activates two simultaneously: GLP-1 and GIP. This dual mechanism is why it consistently produces greater weight loss than older single-action medications. In the SURMOUNT-1 trial (Jastreboff et al., NEJM, 2022) (full publication), participants at 15 mg lost an average of 20.9% of their body weight over 72 weeks - results previously only achievable through bariatric surgery.
This extraordinary efficacy is precisely why global demand for Mounjaro has been so intense - and why supply has consistently struggled to keep pace.
Why Has Mounjaro Been Hard to Get in Ireland?
When tirzepatide was first approved in the US in 2022, demand immediately outstripped Eli Lilly's manufacturing capacity. The FDA placed it on its official drug shortage list in December 2022 - a designation that persisted in various forms for nearly two years. At the height of the shortage in early 2024, four out of six dose strengths were listed as having limited availability nationally.
The reasons were structural. Tirzepatide is a complex peptide molecule - manufacturing it at scale requires highly specialised facilities and cannot simply be ramped up quickly. Eli Lilly's own manufacturing head acknowledged publicly that patients would need to wait years, not months, for new plant capacity. Meanwhile, pharmacies began bulk-ordering to secure stock, which distorted demand signals further.
In Ireland specifically, the problem was compounded because Mounjaro was being prescribed for both weight management and type 2 diabetes - competing for limited supply across two patient populations simultaneously.
The situation has substantially improved. In October 2024, the FDA confirmed the tirzepatide shortage was resolved, following major investment by Eli Lilly - including a confirmed $1.8 billion expansion of its manufacturing facilities in Limerick and Kinsale, Ireland. Supply in 2026 is meaningfully more stable than 2023-2024.
However - intermittent local stock variations still occur, particularly at higher maintenance doses. Not every pharmacy stocks every pen strength, and some doses sell out faster than others. This is why the pharmacy network your provider works with matters as much as the prescription itself.
The Counterfeit Problem: A Serious and Escalating Risk in Ireland
Supply shortages create a vacuum, and that vacuum has been filled by a rapidly growing black market for fake GLP-1 medications in Ireland. The scale is alarming.
The HPRA detained just 40 units of illegal GLP-1 products in 2022. By 2024, that figure had risen to 1,401 units. In the first half of 2025 alone, almost 400,000 units of illegal medicines were impounded by the HPRA working with Revenue's customs officers. The HPRA has removed or amended over 431 websites and social media profiles connected to illegal medication sales.
In October 2025, the HPRA issued one of its most serious warnings. Counterfeit Mounjaro pens were seized in Ireland that contained insulin instead of tirzepatide. Laboratory testing confirmed that two pens contained insulin - a substance that, if injected by someone without diabetes, can cause severe hypoglycaemia, seizures, loss of consciousness, and death if untreated. The pens were visually indistinguishable from genuine Mounjaro.
HPRA WARNING - DO NOT BUY MOUNJARO FROM UNREGULATED SOURCES
The HPRA confirms there are no authorised generic versions of tirzepatide and no authorised tablet or powder form. Any Mounjaro sold as a tablet, powder, or vial - or sold without a valid prescription from an unregistered channel - is illegal and potentially dangerous. Social media advertisements, beauty clinics, and unlicensed websites are not safe sources. No exceptions.
How to make sure you are getting genuine Mounjaro
The following are non-negotiable when accessing Mounjaro safely in Ireland:
- Only accept Mounjaro dispensed by a PSI-registered pharmacy (verify at thepsi.ie) with a valid prescription from an IMC-registered doctor.
- Check that the pen was refrigerated at the pharmacy - ask if unsure.
- Verify the pen's expiry date and that the solution is clear - not cloudy, discoloured, or containing particles.
- Never purchase from social media, beauty clinics, gym suppliers, or unverified websites regardless of how professional they appear.
- Do not use any product sold as Mounjaro in tablet, powder, or vial form - no authorised version exists in these formats.
- If anything about your pen seems wrong - arrived warm, looks different, came from a non-pharmacy source - do not inject it. Contact the HPRA at hpra.ie.
The cold chain - why it matters
Mounjaro must be refrigerated (2-8°C) until opened and can only be kept at room temperature (below 30°C) for 21 days. If the cold chain is broken at any point during storage or transit, the tirzepatide can degrade without any visible change to the pen - meaning you could inject a product that looks normal but contains ineffective medication.
PSI-registered pharmacies are legally required to maintain cold chain integrity. Unregulated sellers are not.
What Does Mounjaro Actually Cost in Ireland in 2026?
Mounjaro is a private prescription medication - not covered by the HSE, Medical Card, or Drugs Payment Scheme for weight management. You pay in full, though prescription medicines qualify for 20% tax relief under Revenue's health expenses scheme. See our guide to claiming tax relief on weight management expenses for how this works in practice. Keep all receipts.
The most important thing to understand is the dose escalation effect. The 2.5 mg starter dose is significantly cheaper than the 15 mg maintenance dose - and many patients are not told this upfront. Here is an honest picture of current Irish market pricing:
2.5 mg - Month 1 (starter)
~€220-€250 / month (medication only)
5 mg - Month 2
~€230-€280 / month
7.5 mg - Month 3
~€280-€350 / month
10 mg - Month 4
~€350-€420 / month
12.5 mg - Month 5
~€420-€520 / month
15 mg - Month 6+ (maintenance)
~€480-€600 / month
These figures are medication cost estimates only and exclude consultation fees, which vary significantly between providers. Prices also vary between pharmacies - sometimes by €50-100 at the same dose - which is why provider pharmacy network access matters. It's always best to check prices with your local pharmacy to confirm.
Bua Health consultation: €50. This covers your full clinical assessment by one of our independent, IMC-registered doctor team, your personalised treatment plan, your first prescription, free dietitian support, and access to the Bua Health patient portal. That is a specialist, doctor-led service with ongoing support - typically cheaper than a one-off consultation at a general GP practice, and with significantly more included.
Medication costs on top of this vary by dose and pharmacy and options can be discussed with the clinical team if eligible.
Critically: not everyone needs to reach 15 mg. Your clinical partner will review your response and tolerability at each stage. Some patients achieve excellent, sustained results at 7.5 mg or 10 mg and maintain that dose - a meaningful difference in ongoing monthly cost. This should always be an open, honest conversation with your clinical team. The 15 mg dose is a ceiling, not a target.
Tax relief note
Mounjaro qualifies as a health expense under Revenue guidelines. You can claim 20% tax relief on both medication costs and consultation fees through Revenue myAccount under Health Expenses. Keep itemised receipts for every prescription and consultation. Step-by-step guidance is in our tax relief guide for weight management expenses.
Who Is Eligible for Mounjaro in Ireland?
Eligibility follows the EMA Summary of Product Characteristics for Mounjaro. You need either:
- A BMI of 30 or above, or
- A BMI of 27-29.9 alongside at least one weight-related health condition - such as type 2 diabetes, high blood pressure, high cholesterol, obstructive sleep apnoea, or cardiovascular disease.
Mounjaro is not suitable if you have a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). It should not be used during pregnancy. Because it slows gastric emptying, it can reduce the effectiveness of the oral contraceptive pill - your clinical partner will advise on this before you start.
