How will the Mounjaro price increase affect your cost? What have companies like Juniper, MedExpress and Asda Online Doctor said about it? Here's everything we know so far.

Mounjaro price increases have hit headlines after it was announced by Eli Lilly (the manufacturer of the weight loss medication) that the cost of the GLP-1 will spike by 170%.

This means the highest dose cost of £122 will go up to £330 per month, with these new figures coming into effect by September 1, 2025.

But why is the price of Mounjaro going up? Well, the company have explained that the increase in pricing has been put in place to align the UK with other European markets as well as maintain NHS patients access to the drug. There is also pressure from the US drug pricing policy.

While those on Mounjaro who have had the weight loss drug prescribed to them via the NHS will not be affected, many users who have decided to go private and pay for the medication have been left questioning how much they will see their Mounjaro bill raise by.

While many suppliers in the UK are yet to comment on how this price increase will affect their customers, here's a breakdown of everything we know from the biggest suppliers of Mounjaro in the UK.

Juniper Mounjaro Price Increase

Juniper is one of the only companies offering Mounjaro which has released a statement about the upcoming increase in the price of the medication.

While Mounjaro is facing a potential 170% price increase, depending on where you get it from, Juniper have previous said they are currently working to make those increases closer to 10%-50%.

In a statement, Juniper wrote: "We know sudden medication price rises can be stressful, especially when you've worked hard to build momentum on your weight loss journey. From 1 September 2025, Eli Lilly, the manufacturer of Mounjaro (tirzepatide), will increase its UK list price to align with other developed countries."

They added: "At Juniper, we expect the impact on our patients to be significantly smaller than some reports suggest."

They are also offering a different weight loss medication, Wegovy, which is priced lower than Mounjaro: "To keep treatment affordable, we're launching a lower-priced Wegovy (semaglutide) offering, as well as making it easier for patients to switch, without starting over, so that effective treatment remains within reach for as many people as possible."
