Why Mounjaro prices differ between pharmacies
At every dose, the gap between the cheapest and dearest pharmacy is between £120 and £132 a month. The medicine is the same Lilly pen wherever you buy it, so the difference comes from the pharmacy's pricing:
- Introductory prices. Some pharmacies discount the first month only. Check what you will pay from month two.
- Discount codes. 15 of the 73 pharmacies currently offer a code, and many work on your first order only. See today's Mounjaro discount codes.
- What's included. Most prices include the online consultation, prescription and standard delivery. A few charge for these separately, or for needles and a sharps bin.
- Bundles. Some pharmacies charge less per month when you buy two or three months at once.
- Lilly's list price. In September 2025 Lilly raised the UK list price of Mounjaro, with the highest dose going from £122 to £330 a month. Today the cheapest 15mg price is £229.
How to pay less for Mounjaro, safely
- Compare the dose you will be on next month, not only the starting dose. Prices rise with each step.
- Check the price after month one, not only the introductory offer.
- Use the discount code shown next to the pharmacy.
- Only buy from a pharmacy on the GPhC register. Every pharmacy on MedEazy has been checked.
- You can change pharmacy to get a better price. The new pharmacy will carry out its own consultation and may ask for proof of your current prescription. See Can I change pharmacy?
- Never buy Mounjaro from social media sellers or websites that don't ask for a consultation.
How we verify UK pharmacies
Every pharmacy listed on MedEazy is checked against the General Pharmaceutical Council (GPhC) public register before it's included. We check it holds a valid registration, is authorised to dispense prescription medicines online and is in good standing. Listings are reviewed regularly, and no pharmacy pays for placement.
About these prices
Prices come straight from each pharmacy and are checked daily. Where a pharmacy offers a discount code, the discounted price is shown. Some pharmacies add a consultation fee, so always confirm the final price at checkout. See today's Mounjaro discount codes.
About the treatment
What is Mounjaro (tirzepatide)?
Mounjaro is a prescription-only injectable medicine containing tirzepatide, approved in the UK for weight management in adults. It mimics two gut hormones, GIP and GLP-1, which help regulate appetite and blood sugar, so you feel fuller and eat less.
Who is it for?
Usually prescribed to adults with a BMI of 30 or above, or 27 or above with at least one weight-related condition such as high blood pressure or type 2 diabetes. A clinical assessment and valid prescription are required; it can't be bought over the counter.
This information is for general guidance only and isn't medical advice. A prescription and clinical assessment are needed before any prescription medicine can be supplied.
Dose steps
Each step usually lasts at least 4 weeks, and your prescriber decides when to move up.
Dosing
Treatment starts at 2.5mg once a week and can be increased in steps up to 15mg, depending on how well you tolerate it and how you respond. Prices vary a lot by dose, so check the table for your current dose.
