A practical comparison of results, cost, dosing, and provider options for Irish patients.
Mounjaro tends to produce greater average weight loss in clinical studies, but it usually costs more in Ireland. Wegovy is often the lower-cost weekly injection and has a dedicated weight-management licence as semaglutide 2.4mg.
The right choice is not simply the strongest medication. It depends on your budget, medical history, side-effect tolerance, current stock, and what a prescribing doctor thinks is appropriate.

|---|---|---|
| Active ingredient | Tirzepatide | Semaglutide |

| Typical Irish cost | EUR300-EUR475/month | EUR220+/month |

| Best fit | Maximum average results, higher budget | Lower monthly cost, semaglutide-specific option |
Do not switch between GLP-1 medications on your own. The safe timing, starting dose, and side-effect plan should be set by a qualified prescriber.

Clinical trial averages show higher weight loss with Mounjaro than Wegovy, but individual results vary. Suitability depends on medical history, tolerance, availability, cost, and a doctor's assessment.
Wegovy is usually cheaper at around EUR220+ per month, while Mounjaro is commonly listed around EUR300-EUR475 per month depending on dose and provider. Always verify current pricing directly with the provider.
Some patients switch, but it should only be done under medical supervision. A doctor needs to review side effects, dosing history, contraindications, and timing between medications.
The online providers listed on GLP-1.ie offer their own medical consultation, so a GP referral is usually not required. It is still sensible to keep your GP informed about any new medication.
