Key Points at a Glance
-
The price increase applies to all Mounjaro doses.
-
This affects all UK providers: no clinic or pharmacy is exempt.
-
The medication itself is not changing: same active ingredient, same results.
-
The decision is made by the manufacturer Eli Lilly, not individual providers.
-
There is no shortage of supply: only the price is changing.
- This will impact the private patients; if you receive an NHS prescription, the price change will NOT affect you
Why is Mounjaro Increasing in Price?
Eli Lilly has confirmed the increase is part of their strategy to match UK prices with those in other developed countries.
When Mounjaro launched in the UK, it was priced lower to improve early access. Now, with more clinical data and a growing patient base, they are adjusting the cost.
As Eli Lilly is the sole supplier, any price change affects all pharmacies and clinics nationwide.

👉 Start your order now – avoid the September price jump.
When Will the Price Change Happen?
The new prices come into effect from 1st September 2025. If you buy Mounjaro privately, you will likely notice the increase on your next order after this date.
📅 Act now before August ends – avoid paying up to £40 more per month.
👉 Lock in today’s price before the rise.
Predicted Post-September Pricing
While individual providers will set final retail prices, early indications suggest:
-
A significant increase of up to 100% per pen is likely
-
Monthly treatment could cost £20–£40 more
-
Higher doses will see the largest total increase
Your Options Before the Price Increase
If you’re concerned about the cost, there are a few ways to plan:
1. Continue Your Current Treatment
If budget isn’t a concern, you can carry on as usual. There are no changes to Mounjaro’s formula, safety, or supply.
2. Purchase in Advance
You may be able to buy multiple months’ supply at the current price before the increase takes effect. Many patients are choosing to secure up to 3 months in advance (if clinically safe and appropriate).
3. Consider an Alternative
Medications like Wegovy (semaglutide) work similarly to Mounjaro and may remain more affordable.
Will the Price Increase Affect Availability?
While the medication will remain in stock, some providers may temporarily sell out in late August due to higher demand from patients buying early.

Can I Get Mounjaro on the NHS?
Currently, Mounjaro is only available on the NHS for patients who meet strict criteria, such as:
-
BMI ≥ 40 (or ≥ 37.5 for certain ethnic groups)
-
At least four obesity-related conditions (e.g., Type 2 diabetes, hypertension)
If you don’t meet these requirements, private treatment is your only option.
Will This Affect NHS Prescriptions?
Mounjaro is available on the NHS, but only for particular patients:
-
BMI ≥ 40, or BMI ≥ 37.5 for certain ethnic backgrounds
-
Must have at least four obesity related conditions (e.g., Type 2 diabetes, hypertension, sleep apnoea)
-
Must meet NICE criteria and be prescribed by a specialist service
If you’re already paying privately, you’re unlikely to meet the NHS requirements for continued supply, meaning the price rise will affect you.
