How We Verify UK Pharmacies
Every pharmacy listed on MedEazy is independently verified against the General Pharmaceutical Council (GPhC) public register before being included in our price comparison tool. We check that each provider holds a valid GPhC registration number, is authorised to dispense prescription medicines online, and is in good standing at the time of listing. Listings are reviewed regularly to ensure continued compliance. We do not accept payment for placement — every pharmacy is listed on the same independent basis.
What is Mounjaro (Tirzepatide)?
Mounjaro is a prescription-only injectable medicine containing tirzepatide, approved in the UK for chronic weight management in adults. It works by mimicking two gut hormones (GIP and GLP-1) that regulate appetite and blood sugar, helping to reduce hunger and calorie intake over time.
Who is it for?
Mounjaro is typically prescribed to adults with a BMI of 30 or above, or a BMI of 27 or above with at least one weight-related health condition such as high blood pressure or type 2 diabetes. A clinical assessment and valid prescription are required — it cannot be purchased over the counter.

Treatment starts at 2.5mg weekly and can be increased in steps up to 15mg, depending on tolerability and clinical response. Prices vary significantly by dose — use our comparison tool above to find the best price for your current dose.
