In Northern Ireland, Mounjaro is available through private prescribing services, with prices generally set by individual providers rather than by a separate Northern Ireland price list. Prices can vary, but private Mounjaro costs are often advertised at around £120 to £340 per month, depending on the strength and provider. The prices shown in this guide range from about £144.99 for the 2.5mg strength to £293.99 for 15mg. Because one Mounjaro KwikPen contains four weekly doses, budgeting for a full year can involve 13 pens rather than 12 calendar month payments.
Northern Ireland and the Republic of Ireland are two different jurisdictions, so Mounjaro pricing and supply rules are not the same. Northern Ireland is part of the UK, while the Republic of Ireland has its own medicines regulator, pharmacy rules, currency and healthcare funding arrangements.
This guide explains Mounjaro costs in Northern Ireland, including the private prices shown above, and how the situation differs in the Republic of Ireland. It also looks at why a Mounjaro pen does not always match a calendar month, what may be included in the advertised price, and what to check when comparing private providers. Prices are provided for general planning only and can change. Whether Mounjaro is suitable for you depends on an individual clinical assessment.
Northern Ireland or the Republic of Ireland? Settle This First
The first thing to check is which country you live in. Northern Ireland and the Republic of Ireland have different healthcare and medicines systems, so a price quoted in one does not automatically apply in the other.
Northern Ireland is part of the UK medicines system. Mounjaro is a UK authorised prescription medicine, and pharmacies in Great Britain and Northern Ireland operate within the relevant UK medicines and pharmacy regulations. Pharmacy regulation differs within the UK, with the GPhC regulating pharmacies in Great Britain and the Pharmaceutical Society of Northern Ireland (PSNI) regulating pharmacies in Northern Ireland.
The Republic of Ireland is a separate country with its own medicines and pharmacy framework. The Health Products Regulatory Authority (HPRA) regulates medicines, while the Pharmaceutical Society of Ireland (PSI) regulates pharmacists and pharmacies. Prices are in euro and may vary between pharmacies and prescribing services.
How Much Is Mounjaro in Northern Ireland Per Month?
The cost of Mounjaro in Northern Ireland depends on the strength prescribed and the provider you use. There is no single price that every private pharmacy must charge.
The prices below show the cost of the different strengths offered by the provider at the time this content was prepared. Prices can change, so always check the current price before ordering.
Mounjaro 7.5mg price Northern Ireland
The 7.5mg pen is listed at £224.99. This is one of the higher strengths used during dose escalation, so the cost may be higher than the starting strength.
Your prescriber will decide whether a dose increase is appropriate based on your treatment and individual circumstances. You should not increase your dose simply because a higher strength is available.
Mounjaro 10mg price Ireland searches
The 10mg pen is listed at £244.99 for Northern Ireland. If you are searching from the Republic of Ireland, this UK price does not apply. Irish pharmacies set their own prices in euro.
If you live in Northern Ireland, use the Northern Ireland price when planning your private treatment costs. If you live in the Republic, check the price with an Irish pharmacy or prescribing service.
Why one pen is not one calendar month
A Mounjaro KwikPen contains 4 doses, with each dose being 0.6ml. When used once a week as prescribed, one pen covers 4 weeks. A calendar year contains more than 48 weeks, so 13 pens may be needed to cover a full year of weekly treatment.
This is worth remembering when comparing annual costs. Looking only at 12 pens may make the yearly figure appear lower than the amount needed for continuous weekly treatment.
Is Mounjaro Cheaper in Northern Ireland?
There is no standard Northern Ireland discount or separate regional tariff that applies to every provider. Private pharmacies and prescribing services set their own prices, so the cost can differ between providers.
When comparing prices, look at more than the pen itself. Check whether the price includes the clinical assessment, prescription, delivery, ongoing support and any other fees.
Mounjaro also needs to be stored and transported within the temperature conditions stated in the product information. Before first use, the KwikPen should be stored in a refrigerator at 2 to 8°C and should not be frozen.
How Much Is Mounjaro in Ireland Per Month?
In the Republic of Ireland, Mounjaro is available on prescription, and private treatment costs can vary between providers.
The amount you pay may include the medicine itself as well as a consultation or weight management programme fee, depending on the service you choose.
If you are considering private treatment in Ireland, ask the provider for the total cost rather than looking only at the price of the pen.
Why Mounjaro prices in Ireland vary between pharmacies
There is no single private price for Mounjaro across the Republic of Ireland. Pharmacy prices and any additional service fees can vary.
Searches such as Mounjaro price Ireland 2026, Mounjaro cost Ireland 2026, cost of Mounjaro Ireland and how much is Mounjaro Ireland can therefore produce different figures.
If you are comparing prices, ask whether the quoted amount includes the prescription, consultation, dispensing and delivery. This can help you compare the actual cost more fairly.
Could Mounjaro cost less in Ireland in future?
It is possible that the cost or reimbursement position could change in the future. Pricing and reimbursement decisions in Ireland involve the relevant healthcare authorities and can change over time.
If Mounjaro becomes available through a public reimbursement scheme for a particular use, the amount eligible patients pay could be different from the current private price. Check the latest information from the HSE or your healthcare professional rather than relying on older price information.

Can a UK Pharmacy Deliver Mounjaro to the Republic of Ireland?
Do not assume that a UK pharmacy can simply post Mounjaro to an address in the Republic of Ireland. Cross border supply of prescription medicines is subject to legal and regulatory requirements, including rules around who can prescribe and dispense medicines in Ireland.
If you live in the Republic of Ireland, the appropriate route is generally to use a healthcare professional and pharmacy operating within the Irish healthcare system.
If you live in Northern Ireland, you can use an appropriately registered Northern Ireland pharmacy or another UK provider that can lawfully supply to your address.
If you see a website offering cross border delivery, check that it is authorised to supply prescription medicines to your location before placing an order.
What the Advertised Price Does Not Include
A headline price does not always show the full cost of treatment.
For example, Mounjaro KwikPen packs do not include needles. You need a new compatible needle for each injection, and you may also need a suitable sharps container.
Also check whether the advertised price includes:
- The clinical consultation
- The prescription
- Dispensing
- Standard delivery
- Temperature controlled delivery, where applicable
- Ongoing clinical support
- Any additional service or programme fees
Be particularly careful with introductory offers. A discount on your first order may not apply to later orders, so compare the standard price as well as the promotional price.
Cheapest Mounjaro Northern Ireland: How to Compare Without Being Misled
It can be tempting to search for the cheapest Mounjaro price, but the lowest advertised figure does not always represent the lowest overall treatment cost.
A simple Mounjaro price comparison can help. Check:
- Compare the same strength, because prices can vary considerably between doses.
- Check the standard price rather than only a first order discount.
- Look at the full price range, especially if your prescribed strength may change.
- Add any consultation, prescription, delivery, needle or support fees.
- Compare the total cost over the period you are planning, remembering that one KwikPen contains 4 weekly doses.
These checks can give you a clearer picture of what you may actually spend.
The same approach can be used for a Mounjaro price comparison UK. If you are comparing providers in the Republic of Ireland, compare prices in euro and check the full cost of the Irish service rather than using UK prices as a reference.
Why the Lowest Price Is Not Always the Real Price
A very low price should be treated with caution, particularly if the seller does not require a prescription or proper clinical assessment.
Mounjaro is a prescription only medicine. UK health authorities have warned about falsified and unlicensed weight loss medicines being sold through unauthorised channels. Buying from an unregulated seller can make it difficult to confirm what the product contains or whether it has been stored correctly.
If you receive a Mounjaro pen that looks unusual, appears damaged or does not match the official product information, do not use it until you have spoken with a pharmacist or healthcare professional.
Getting Mounjaro in Northern Ireland
People in Northern Ireland may be able to access Mounjaro privately through an appropriate prescribing service if a qualified prescriber considers it suitable.
For weight management, Mounjaro is authorised for eligible adults with a BMI of 30 kg/m² or higher, or a BMI of 27 kg/m² to less than 30 kg/m² with at least one weight related health condition. Meeting these criteria does not guarantee that a prescription will be issued. The prescriber must consider your individual circumstances.
Treatment usually starts at 2.5mg once weekly for 4 weeks. The dose can then be increased in 2.5mg steps after at least 4 weeks on the current dose, when appropriate. The maximum adult dose is 15mg once weekly.
Mounjaro contains tirzepatide, which acts on both GIP and GLP 1 receptors. Clinical studies have shown weight loss in adults using tirzepatide, but individual results vary and clinical trial results should not be treated as a promise of a particular amount of weight loss.
If you are considering private treatment, compare the full cost, prescribing process, pharmacy registration and level of clinical support rather than choosing a provider based only on the advertised price.
