Everything You Need To Know About the UK Mounjaro Price Increase (August 2025 Edition)

Mounjaro has been a popular prescription option for weight loss and type 2 diabetes management in the UK, but recent news has hinted at price changes. For many people, this has raised concerns about affordability, access and whether they should consider switching to alternative treatments such as Wegovy.

This article will explain what is happening with Mounjaro prices, why the changes are taking place, what this could mean for patients and what other options may be available. It will also outline whether switching to Wegovy is possible and how to choose the correct dosage if you make the change.

Key Takeaways

Here are the five biggest takeaways from this article about Mounjaro price changes in the UK:

• Mounjaro prices in the UK could increase from September 2025, with higher costs affecting thousands of patients.

• The price changes are partly due to controversial US President Donald Trump making complaints about the cost of medications in the United States.

• Patients may face increased costs, which could influence whether they continue Mounjaro or move to alternative treatments.

• Wegovy is now expected to be a more affordable option for many patients, with similar results for weight loss and metabolic health.

• Switching from Mounjaro to Wegovy needs careful attention to dosage and should be done under the guidance of a healthcare professional.

Are Mounjaro prices changing?

Potentially. The cost of Mounjaro in the UK may rise significantly from September. The manufacturer of Mounjaro, Eli Lilly, has confirmed that prices will increase across all strengths of the medication. This will affect people receiving Mounjaro on private prescriptions.

For people using Mounjaro for weight loss or type 2 diabetes management, the price hike could mean higher monthly costs. For some, this may make continuing treatment less financially viable [1].

Why could Mounjaro prices change?

Several factors can lead to medication price changes. In this case, Eli Lilly has stated that they are raising the price of Mounjaro by as much as 170% due to: “Aligning prices more consistently to ensure fair global contributions to the cost of innovation”. 

This change comes after controversial US President Donald Trump made complaints about the high cost of drugs in the United States. In a response to Trump, Eli Lilly released the following statement:

“The UK was one of the first countries where Lilly launched Mounjaro and our priority was to bring it to patients as quickly as possible during a time of limited availability.

"At launch, Lilly agreed to a UK list price that is significantly below the European average to prevent delays in NHS availability.

"With changes in the environment and new clinical evidence supporting the value of Mounjaro, we are now aligning the list price more consistently to ensure fair global contributions to the cost of innovation."

What does this mean for Mounjaro users?

UK Meds’ Mounjaro prices will remain in place for as long as they can be maintained. Over the next few weeks, there may be some temporary stock issues as Eli Lilly has placed a cap on the amount we can order. Please rest assured, we are doing everything we can to keep disruption to a minimum.

This change could also make alternatives such as Wegovy more appealing. In many cases, Wegovy will now be the more affordable option for people who require ongoing weight management support.

What alternatives to Mounjaro are there?

The most direct alternative to Mounjaro is Wegovy, another GLP-1 receptor agonist that works in a similar way to help regulate appetite and support weight loss. Wegovy has been available in the UK for weight management since 2023 and has a proven track record in clinical studies.

While there are other weight loss treatments available, including Saxenda and oral medications such as Orlistat, these may not be as effective for every patient. For many, Wegovy will be the first choice alternative because it offers comparable weight loss results to Mounjaro, with the benefit of potentially lower costs following the price changes.

Can I switch to Wegovy if I have used Mounjaro?

Yes, it is possible to switch from Mounjaro to Wegovy. Although both medications belong to the same drug class, they have different active ingredients and dosing schedules.

You can buy Wegovy online from UK Meds in the same way as Mounjaro. You will need to complete our online consultation, complete your FitXpress body scan and then wait until your consultation is approved by an independent prescriber. If approved, your order will be delivered to you.

What Wegovy dosage should I use?

If you switch from Mounjaro to Wegovy, you will not usually start on the highest dose. Instead, the most common approach is to take a short break between medications, begin at the lowest strength and gradually increase over several weeks. This helps your body adjust to the medication and reduces the risk of side effects such as nausea or gastrointestinal discomfort.

Gradual dose increases (known as titration) are important to ensure both safety and effectiveness and skipping this process can increase the risk of complications. Consider reading our guide to Wegovy dosing and titration prior to making the switch to fully inform yourself.

Final Thoughts

Mounjaro price increases will affect many people in the UK who rely on the medication for weight loss or type 2 diabetes management. Understanding why prices are rising, what this means for ongoing treatment and what alternatives exist can help patients make informed decisions. For those considering switching to Wegovy, it is essential to follow medical guidance to ensure safe and effective results.
