Mounjaro Price Increases September 2025

Have you heard Mounjaro prices are going up in September? If you’re using it now, or planning to start soon, changes like this can cause real worry. Unfortunately, the increase will affect every pharmacy in the UK, and the timing means it could impact your next dose sooner than you expect.

Why is Mounjaro going up in price in September 2025?

From 1st September 2025, the price of Mounjaro will be increasing across the UK. The manufacturer, Eli Lilly, has said this change is part of a wider review to bring UK prices more in line with what patients pay in other countries.

It’s not a decision made by individual pharmacies, which means the new price will apply everywhere, whether you use a local chemist or order online. The increase comes at a time when demand for Mounjaro is higher than ever and supply chains are under ongoing pressure to keep up.

We know how important it is to keep your treatment on track. We will always do everything we can to keep our prices competitive and affordable for our patients.

What the Timing Means for Your Dosing Schedule

Because the increase takes effect from 1st September, the point at which you place your next order could make a big difference. If your next pen is due before the end of August, you’ll still pay the current price. But if you need to order in September or later, your treatment will be charged at the new, higher rate.

For some patients, this timing could mean switching to a higher price partway through their treatment plan. That can be frustrating, especially if you’ve already mapped out your dose increases over the coming months and budgeted accordingly. 

Planning ahead now could help you avoid an unexpected jump in cost and keep your schedule on track.

Risks of Pausing or Stopping Mounjaro

With a price increase on the way, it’s natural to worry about the financial impact, and you may be considering stopping taking Mounjaro altogether, or pausing your treatment plan until you work out what you want to do.

Stopping Mounjaro suddenly (“going cold turkey”) isn’t dangerous in the sense of withdrawal, but it can cause a quick return of appetite and cravings. 

Without the appetite control and slower digestion the medication provides, it’s much easier to eat more than your body needs, which can lead to rapid weight regain. Other benefits, like improved blood sugar control and reduced cravings, can also fade quickly.

If you stop and later decide to restart, there’s another risk: your weight might have dropped below the eligibility threshold for starting treatment again. This could mean you’re no longer able to get Mounjaro, even if you want to continue. And if you are eligible, you may still need to restart at a lower dose and work your way back up.

If you are sure you want to stop, it’s helpful to step down through lower Mounjaro maintenance doses to give your body and appetite more time to adjust. While it’s not medically required, it can make the transition off Mounjaro feel more manageable.

What weight loss medications can I use if Mounjaro becomes too expensive?

If the September price rise means you can’t afford to carry on using Mounjaro, it doesn’t necessarily mean your weight loss journey has to stop. Other options may work for you, depending on your health needs and eligibility.

One of the main alternatives is Wegovy. Like Mounjaro, it works by slowing digestion and reducing appetite, helping you feel fuller for longer. It’s also a once-weekly injection available through our online weight loss clinic. A lot of Mounjaro users will meet the Wegovy BMI requirements, so it can be a good choice for those looking for continued progress.

Wegovy works similarly to Mounjaro, but it targets one hormone receptor instead of two. Many people still experience impressive results, and the benefits can go beyond weight loss. Patients report improvements in areas like blood sugar control and heart health. However, you’ll usually need to wait around four weeks after stopping one before starting the other, to reduce side effects and allow your body to adjust.

Some people may also be eligible for other weight loss medications, like Saxenda (liraglutide) or Orlistat, though these work in different ways and may have different dosing schedules. If cost is your main concern, we can help you compare options so you can continue treatment in a way that suits your goals and budget.
