Mounjaro vs Wegovy in Ireland
A practical comparison of results, cost, dosing, and provider options for Irish patients.
The short answer
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.
| Feature | Mounjaro | Wegovy |
|---|---|---|
| Active ingredient | Tirzepatide | Semaglutide |
| Mechanism | Dual GIP + GLP-1 | GLP-1 receptor agonist |
| Typical Irish cost | EUR300-EUR475/month | EUR220+/month |
| Injection schedule | Weekly | Weekly |
| Dose escalation | 2.5mg up to 15mg | 0.25mg up to 2.4mg |
| Best fit | Maximum average results, higher budget | Lower monthly cost, semaglutide-specific option |
When Mounjaro may make sense
- You are aiming for the highest average weight-loss outcome and can afford the higher monthly cost.
- You have discussed the dual GIP + GLP-1 mechanism with a prescriber and it is appropriate for your history.
- You have tried a semaglutide option before and the result was not enough, subject to medical review.
When Wegovy may make sense
- You want a weekly semaglutide option that is usually cheaper than Mounjaro.
- You are starting GLP-1 treatment for the first time and want a well-established weight-management pathway.
- You prefer a lower monthly medication budget, with the tradeoff that average results may be lower than Mounjaro.
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.
