Mounjaro Price Changes Explained

As Eli Lilly, the manufacturer of Mounjaro (tirzepatide) injection, has decided to increase its price by September 2025, many people are confused and wondering which alternative they should opt for and whether switching makes financial sense.

  • Mounjaro price will increase by 170% for the highest maintenance dose of 15 mg.
  • Wegovy will be the best alternative as it is significantly less expensive
  • Our professional team will support your safe switch from Mounjaro to Wegovy

What is happening with Mounjaro prices in the UK?

Eli Lilly is increasing the private list price of Mounjaro in the UK by 170% for the highest maintenance dose. At launch, the price of Mounjaro was lower to ease access for both NHS and private patients. But now this move is designed to align UK prices with those in other developed countries.

Moreover, this move is seen as a strategic response to pressure from the US pricing policy, where lowering US prices depends on raising them elsewhere. However, NHS patients are unaffected, since NHS supply contracts remain in place under separate terms.

Can I switch to Wegovy?

Yes, you can switch to Wegovy, but it must be done under medical supervision to reduce side effects and ensure safe and effective weight management. Wegovy contains semaglutide and targets GLP-1 receptors, regulating your appetite and food intake. People in the UK are switching to Wegovy due to:

  • Mounjaro’s price hike

    The price of Mounjaro shot up dramatically, making it less accessible for many private users.

  • Wegovy is a more affordable alternative

    Although Wegovy is not cheap, it has become relatively more budget-friendly and has pushed many to consider Wegovy for their long-term weight management.

  • Effectiveness

    Wegovy’s manufacturer has submitted a new dose of 7.2 mg to the EMA (European Medicines Agency). This dose is still in Clinical Trials and will be available soon. Clinical trials have shown that patients who have taken this new strength have lost around 25% of their initial body weight within 72 weeks compared to 16.7% of those taking 2.4 mg.

  • Offer heart benefits

    Wegovy is approved in the UK for weight management and licensed for heart health. It reduces the risk of heart attack, stroke, or death by 20% in obese or overweight people with existing heart disease, even if they do not have diabetes.

  • Final things to consider

    Wegovy causes fewer injection site reactions

    You will need a wash-out period of 1–2 weeks after your last dose of Mounjaro before starting your first dose of Wegovy.

    Please consider the long-term cost implications of treatment.

    Patients need to titrate to the higher doses of Wegovy to achieve the average weight loss result of around 17%. In comparison, clinical trials show about 16% weight loss on 5mg of Mounjaro.

    0.25mg Wegovy may not provide the same level of hunger suppression as your current Mounjaro dose, which could affect your progress. We are not able to prescribe a higher starting dose when switching. You could increase the dose after 4 weeks.

    If you decide to switch back to Mounjaro in the future, you would need to restart at 2.5mg.

  • When is the price of Mounjaro increasing?

    Eli Lilly has announced that the price of Mounjaro will increase by up to 170%, effective from 1 September 2025. The price change will only affect those who purchase Mounjaro privately, whether through a private pharmacy, clinic, or online provider such as Ashcroft Pharmacy.

  • I am a weight loss patient on Mounjaro. What does this mean for me?

    If Mounjaro price increases, it could mean higher monthly costs for your weight loss journey, especially if treatment is long-term. You may need to reassess your budget, check if insurance or the NHS covers part of it, or explore alternatives such as Wegovy. However, if you are ok with price increases, stick with Mounjaro.

  • What does Mounjaro do?

    Mounjaro is a prescription medication that regulates your blood sugar level and supports weight management. It mimics two natural hormones, i.e., GLP-1 and GIP, slowing digestion, reducing appetite, and managing type 2 diabetes.

  • Why are you recommending switching from Mounjaro to Wegovy?

    People are switching from Mounjaro to Wegovy due to the recent Mounjaro price hike in the UK, making it less affordable for many patients. Wegovy is a more affordable option with proven heart benefits and a well-established option for weight management with clear guidance for safe use.

  • What is better for long-term results, Mounjaro or Wegovy?

    Mounjaro and Wegovy are highly effective for long-term weight management; the selection depends on your budget, medical history, health goals, and tolerance to side effects. So, the doctor’s guidance is key.

  • Will switching from Mounjaro to Wegovy affect my weight loss progress?

    Switching from Mounjaro to Wegovy does not affect or halt your weight loss progress. With medical guidance, the right dosage, and consistent lifestyle changes, most people continue losing weight smoothly after the switch.

  • Does the price increase only affect Mounjaro?

    The price increase will only affect Mounjaro; the other weight loss medications will remain unaffected as no other manufacturers have stated that they are increasing the prices. However, it does not mean that providers would not choose to raise prices on other treatments.

  • Will I get the same side effects on Wegovy as Mounjaro?

    Mounjaro and Wegovy cause the same side effects, such as vomiting, diarrhea, nausea, constipation, etc. Some people may tolerate one better than the other; however, individual response varies. Always monitor side effects and consult your healthcare provider.

  • How will the stocks of Mounjaro be affected?

    If Mounjaro's price increases, Eli Lilly’s profit margin and revenue will increase in the short term, boosting investor confidence and stock performance. However, higher costs will limit patient access and drive switches to alternatives such as Wegovy, creating long-term pressure.

  • Could my weight plateau or increase when I switch?

    While switching from Mounjaro to Wegovy, you may experience a temporary weight plateau or gain. It is normal and occurs as your body adjusts to the new medicine and dosage. With consistent lifestyle changes and medical guidance, progress usually resumes.

  • Will I still get support with Wegovy?

    Yes, you will get professional support with Wegovy. Ashcroft Pharmacy offers regular check-in, guidance on dosing, and lifestyle advice, helping you manage side effects and track progress.

  • Can I buy multiple Mounjaro pens early?

    You can order up to three Mounjaro pens before 1 September 2025, depending on your insurance, pharmacy, and prescribing doctor. Consult your pharmacy and prescriber to determine what is allowed under your plan.

  • Can I buy Mounjaro doses I do not need yet?

    You can buy Mounjaro doses in advance, but it depends on your pharmacy’s stock, prescription limit, and insurance rules. Some pharmacies may restrict advance purchase to prevent stockpiling, while others may allow it if you pay out of pocket.

  • Can I switch to Ashcroft Pharmacy from another provider?
