Mounjaro in the UK: Everything You Need to Know (Q&A)
With rising interest in GLP-1 medications for weight loss and type 2 diabetes, Mounjaro (tirzepatide) is rapidly becoming one of the most talked-about treatments in the UK. In this comprehensive Q&A, we answer the most common questions people have about Mounjaro, including how it works, who it’s for, and how you can access it safely through a trusted UK pharmacy.
What is Mounjaro?
Mounjaro is a prescription-only injectable medication containing tirzepatide, a dual GIP and GLP-1 receptor agonist. It was developed by Eli Lilly and is primarily licensed for type 2 diabetes, but has also shown significant weight loss benefits.
How does Mounjaro work?
Tirzepatide mimics two hormones — GLP-1 and GIP — that:
- Reduce appetite and food cravings
- Slow stomach emptying
- Help regulate blood sugar levels
This dual-action approach makes it more effective than older GLP-1 medications like Ozempic or Saxenda in clinical trials.
Is It approved for weight loss in the UK?
As of now, Mounjaro is approved for type 2 diabetes in the UK via prescription.
Its use for weight loss is considered off-label, but many UK doctors and online clinics prescribe it for patients with:
- A BMI over 30 (obesity), or
- A BMI over 27 with weight-related health risks (e.g., high blood pressure, PCOS)
Is Mounjaro better than Ozempic?
Clinical trials (like SURPASS and SURMOUNT) suggest that Mounjaro leads to greater average weight loss than Ozempic or Wegovy.
For example:
- Mounjaro: up to 22.5% body weight loss
- Ozempic: around 15%
But results can vary by individual.
How do you take it?
- Once-weekly injection under the skin (abdomen, thigh, or upper arm)
- Usually starts at 2.5 mg and can increase over time to 15 mg, depending on how well you tolerate it
What are the side effects of Mounjaro?
Most common side effects:
- Nausea
- Vomiting
- Diarrhoea
- Constipation
- Fatigue
Serious side effects are rare but may include pancreatitis or gallbladder issues. Always speak to a pharmacist or GP if symptoms are severe.
Is it safe for everyone?
No. Mounjaro is not suitable for:
- People with a history of pancreatitis
- Pregnant or breastfeeding women
- Those with certain thyroid conditions
Always consult a UK-registered prescriber before use.
Do I need a prescription for it in the UK?
Yes. Mounjaro is a prescription-only medicine (POM) in the UK.
You can’t legally or safely buy it over-the-counter or from unregulated sources.
How much does Mounjaro cost in the UK?
