Weight Loss at Curate
Mounjaro vs Wegovy, compared properly.
Both are once-weekly injections licensed in the UK for weight management. They work in related but different ways, and the right one for you is a clinical decision — here's what actually differs.
The short version
Mounjaro's active ingredient is tirzepatide, which mimics two of the body's own hormones — GLP-1 and GIP — to act on appetite and metabolism. Wegovy's active ingredient is semaglutide, which mimics GLP-1 alone. Both are taken as a weekly injection with a dose that steps up gradually, and both are prescription-only medicines: a UK clinician decides whether either is suitable for you.

Questions
Mounjaro vs Wegovy, answered.
Which is more effective, Mounjaro or Wegovy?
Individual response varies widely with either medicine, and the right comparison is against your own health profile, not an average. Your clinician weighs your history, goals and any previous GLP-1 experience before recommending one — outcomes depend as much on the wrap-around care and dose management as the molecule.
Can I switch from Wegovy to Mounjaro, or the other way?
Sometimes, yes — but never on your own. Switching involves a clinical decision about equivalent dosing and timing, so it always goes through a clinician review at Curate.
Are the side effects the same?
The common side effects of both are gastrointestinal — nausea, constipation or diarrhoea, most noticeable in the first weeks and after dose increases (SmPC, 2025). The full profiles differ in detail; your clinician talks these through before you start.
Why is Wegovy cheaper than Mounjaro?
They're different medicines from different manufacturers, each with its own UK list price. Price alone isn't a reason to pick one — suitability comes first, and your clinician will explain the trade-offs for your situation.
