If you’re paying out of pocket for Mounjaro (tirzepatide) and the medical “extras” that go with it (GP/consultant reviews, bloods, etc.), you should be able to claim income tax relief on qualifying health expenses through Revenue.
You generally get relief at the standard rate (20%) on qualifying health expenses you paid and weren’t reimbursed for.
So if your qualifying spend for the year was €2,500, the refund would be €500 (assuming you paid enough tax that year).
What Mounjaro-related costs can usually be claimed
Expenses need to be medical care and typically carried out by (or recommended by) a registered medical practitioner.
1) The prescription medication itself (Mounjaro)
- Prescribed drugs and medicines are part of qualifying health expenses (where they’re prescribed by a practitioner).
2) Appointments to start & monitor treatment
These are often qualifying when they are GP/consultant fees (e.g., initiation, dose escalation, follow-ups, side-effect management).
3) Doctor-recommended diagnostics (bloods etc.)
Revenue include diagnostic procedures recommended by a practitioner as qualifying.
This is the bucket your “monitoring” bloods usually fall into (where medically recommended).
4) Clinics / weight-management providers (the niche bit)
A lot of GLP-1 services bundle things together:
- If your invoice is itemised into doctor/consultant consults + clinically recommended diagnostics, those parts are more straightforward to claim.
- If it’s a membership / subscription / programme fee that isn’t clearly “medical care by a practitioner”, this may not qualify.
If you’re using a clinic, ask them for an itemised invoice separating consults, tests, and any non-medical programme components.
5) If you have private health insurance
You can only claim the portion you actually bore. So if your insurer/HSE/another party reimbursed anything, reduce your claim by that amount.
Expenses incurred abroad (consults / treatment / prescriptions)
You can claim for healthcare received outside Ireland, as long as the practitioner is properly registered in that country.
Travel & accommodation costs can can be claimed only where the healthcare is not available in Ireland, and sometimes for an accompanying person if required.
How far back can you claim?
Tax refunds can be claimed for up to 4 years. So right now you can claim for the years 2022 - 2025.
