Wegovy vs Mounjaro in Spain
Both Wegovy and Mounjaro are once-weekly prescription treatments used as part of a medically supervised weight loss plan. The key question is not simply which one is more popular, but which one is more likely to suit you best.
In broad terms, Mounjaro is often seen as the stronger option for average weight loss results, while Wegovy remains a very established and widely requested treatment. The right choice depends on your BMI, medical history, side effects, previous treatment response, availability and price.

A quick summary for patients deciding which route to ask about first.
Quick verdict
If you are asking which one tends to look stronger in direct comparisons, the answer is often Mounjaro. If you are asking which one is the better fit for you personally, that needs a doctor-led review.
What matters most?
Strength is only one factor. Cost, tolerability, long-term sustainability and your own medical background matter just as much.
Understanding the real differences
Most people searching for “Wegovy vs Mounjaro” want a proper comparison, not just a sales pitch. They usually want to know which one tends to work better, what the side effects are like, which one may be cheaper, and whether they are even suitable for treatment.
That is why this page is structured as a genuine comparison guide first, with the booking option built in naturally.
Which one is better?
For many patients, Mounjaro may offer greater average weight loss. But “better” does not only mean stronger. It can also mean easier to tolerate, more affordable, easier to access, or simply more appropriate for your own medical situation.
In real practice, the best medication is the one that is both appropriate and sustainable.

Wegovy
Wegovy contains semaglutide. It is designed to reduce appetite, help you feel fuller and support weight loss when combined with a lower-calorie diet and lifestyle change.
Mounjaro
Mounjaro contains tirzepatide. Because it works on both the GLP-1 and GIP pathways, it is often viewed as the stronger option when patients compare average weight loss results.
Which one tends to win in direct comparisons?
If you focus on the question most patients care about — which one tends to produce greater average weight loss — Mounjaro usually comes out ahead. That is why it gets so much attention in online comparison searches.
But in real prescribing practice, stronger does not automatically mean better for every patient. Cost, tolerability, availability and your own medical background still matter.
- You want to ask about the stronger average weight loss option.
- You are comparing both from scratch and want to discuss the most effective route first.
- You understand that stronger does not mean guaranteed or side-effect free.
- You want a well-established semaglutide-based option.
- Price matters and you are looking at the slightly cheaper route.
- Your doctor feels Wegovy is the more suitable or more sustainable treatment for your situation.
What about a tablet version of Wegovy?
A tablet form of semaglutide for weight loss is a major development to watch. For patients who do not like injecting themselves, this could become a very attractive option when it becomes more widely available.
For now, the practical message for patients in Spain is simple: the tablet route is one to watch, but not one we would currently present as available in Spain yet.
Our current position
As soon as a tablet form for obesity is properly available on the Spanish market, it is something we would expect strong patient interest in, especially from those who prefer not to self-inject.
Until then, the current comparison remains mainly between the injectable forms of Wegovy and Mounjaro.
Are the side effects very different?
In practical terms, the side effect conversation is often quite similar with both medicines, especially during dose increases.
- Nausea
- Constipation
- Diarrhoea
- Reduced appetite
- Digestive discomfort
This is why follow-up matters. Starting treatment is only part of the process. Monitoring tolerance and adjusting the dose properly is just as important.
Important before you ask for either treatment
These medicines are not suitable for everyone. A proper prescribing review is needed before any recommendation is made.
- Your medical history matters.
- Your current medications matter.
- Your BMI and any obesity-related conditions matter.
- Previous side effects or intolerance matter.
