What is Mounjaro?
Mounjaro is the brand name for tirzepatide, a medication developed by Eli Lilly. It was originally approved for type 2 diabetes management and subsequently approved for chronic weight management in adults with obesity or overweight with at least one weight-related health condition.
Unlike older GLP-1 medications such as Wegovy (semaglutide) or Saxenda (liraglutide), Mounjaro works on two hormonal pathways simultaneously: it activates both the GLP-1 (glucagon-like peptide-1) receptor and the GIP (glucose-dependent insulinotropic polypeptide) receptor. This dual mechanism is believed to be the reason it produces greater weight loss than single-receptor GLP-1 drugs.
Why many patients compare Mounjaro first
In the SURMOUNT-1 clinical trial — the largest weight loss trial of any GLP-1 medication — participants taking the highest dose of Mounjaro (15mg weekly) lost an average of 22.5% of their body weight over 72 weeks. That is roughly equivalent to losing 22kg if you start at 100kg.
By comparison, Wegovy (semaglutide 2.4mg) produced an average weight loss of around 15% in its pivotal trial (STEP-1). Trial averages are useful for comparison, but individual results vary and tolerability, contraindications, cost and provider support all matter.
Mounjaro Cost Breakdown by Dose — Ireland 2026

|---|---|---|---|
| 2.5mg | Starter (Month 1–2) | ~€300/mo | Lowest dose. Tolerance-building phase. |
| 5mg | Month 3–4 | ~€330/mo | First maintenance step for most patients. |
| 7.5mg | Month 5–6 | ~€370/mo | Significant weight loss typically begins here. |
| 10mg | Month 7–8 | ~€400/mo | Common long-term maintenance dose. |
| 12.5mg | Month 9–10 | ~€440/mo | Higher escalation for greater results. |

Mounjaro vs Wegovy — Which Should You Choose?
Choose Mounjaro if: You want maximum weight loss results and can afford the higher monthly cost (€300–475 vs €220+ for Wegovy). Mounjaro also tends to work well for people who have previously tried semaglutide without sufficient results.
Choose Wegovy if: Cost is a key factor, or if you prefer to start with a well-established, slightly cheaper option. Wegovy still produces excellent results (~15% body weight loss) and has a longer track record.
