What is Mounjaro?

Mounjaro is a dual-action treatment that mimics both the GIP and GLP-1 hormones, leading to increased feelings of satiation and fewer side effects than Wegovy.

How does Mounjaro work?

Mounjaro is the first approved dual-acting GLP-1/GIP once-weekly weight loss treatment. Mounjaro acts on glucagon-like peptide-1 (GLP-1) and another hormone pathway called glucose-dependent insulinotropic polypeptide (GIP), which promotes fat loss and blocks fat gain. By combining the effects of GLP-1 and GIP agonists together, this treatment is more effective at promoting weight loss by controlling appetite, promoting fat loss and preventing fat gain.

Is Mounjaro more effective than other weight loss medications?

While there are no published head-to-head trials at this stage, comparing the respective clinical trials of Mounjaro and Wegovy, Mounjaro patients reached 20.9% at 72 weeks weight-loss vs. 14.9% at 68 weeks for Wegovy patients.

How effective is Mounjaro for weight loss?

According to clinical trials, Mounjaro is the most effective medication for weight loss available right now. 



One study1 of over 2,500 patients from July 2022 found up to 90.9% of patients were able to achieve at least 5% weight loss, Up to 83.5% were able to achieve at least 10% weight loss and 56.7% were able to achieve at least 20% weight loss in 72 weeks of treatment.

FAQs

What is Mounjaro?

Mounjaro (tirzepatide) is a once-weekly injection for weight loss.

By combining the effects of GIP and GLP-1 receptor agonists together, tirzepatide is more effective at promoting weight loss through decreased appetite, as well as directly impacting the pathways that lead to fat loss. This helps to make you feel fuller far more quickly, assists with turning down cravings and stimulates the breakdown of fat.

How does Mounjaro work?

Other injectable weight loss medications only act on GLP-1 receptors. Mounjaro acts on GLP-1 and another hormone pathway called glucose-dependent insulinotropic polypeptide (GIP), that together promote fat loss and blocks fat gain. By combining the effects of GLP-1 and GIP together, this medication can be more effective at promoting weight loss through reduced appetite, as well as directly on the pathways that lead to fat loss while retaining lean muscle mass.

Is Mounjaro more effective than other weight loss medications?

According to clinical trials, Mounjaro (tirzepatide) is the most effective treatment for weight loss that is available right now. There have been several studies on the results of this treatment and it outperforms other GLP-1 treatments like Wegovy for weight loss results.

One study of over 2,500 patients from July 2022 found an average of up to 20.9% body weight loss in patients on tirzepatide after 72 weeks, compared to Wegovy where the average weight loss was up to 14.9% after 68 weeks.

What are the side effects for Mounjaro?'

Medication affects everyone differently and you may experience no side effects when taking Mounjaro. The most common side effects experienced by patients on Mounjaro are similar to those experienced with other GLP-1 medications. These can include nausea, vomiting, diarrhoea, constipation and indigestion.

These symptoms usually subside after your body adjusts to the medication over the first few weeks. You can reach out to Juniper’s Care Team of nurses, pharmacists at any time if you need assistance with side effect prevention and management.

What happens if I forget to take my dose?

Although you can take your dose whenever you want on your scheduled day, try to take it at a similar time to prevent accidentally missing a dose.

If you miss or forget your dose, it should be administered as soon as possible, provided it's within 4 days of your usual injection day.

If your next dose is more than 4 days have passed, skip the missed dose and administer the next dose on your normal scheduled day, do not take the missed dose. Instead, wait for your regular scheduled dose day to administer it.

If it's longer than 10 days since your last dose, you may need to recommence Mounjaro at a reduced dose to prevent severe side effects from occurring once you restart.

Please get in touch with our Care Team at hello@myjuniper.co.uk so they can advise you accordingly.

How do I increase my dose?

Start with a low dosage of 2.5mg once a week and increase gradually to 5mg and then 10mg every 4 weeks.

Most will follow the dosage schedule below, but be sure to follow your individual treatment plan as it may be different:

  1. Week 1-4: Inject 2.5mg weekly (1 dose per week)
  2. Week 5-8: Inject 5mg weekly (1 dose per week)
  3. Weeks 9-12: Inject 7.5mg weekly (1 dose per week)
  4. Week 13+: Inject 10mg weekly (1 dose per week)

Our Care Team will maintain regular contact with you during the initial months of treatment to monitor your progress, address any side effects, and place you in touch with your prescriber to make necessary dose adjustments.

Please reach out to our Care Team at hello@myjuniper.co.uk if you wish to remain on a lower dose and we can place you in touch with your prescriber.

Higher doses of medication may be available from the manufacturer, but are not suitable for everyone. Your prescriber will determine if it is appropriate to move to a higher dose.

Do not increase your dose early as this will not improve your results and will most likely lead to increased side effects.

These dosage increases are not compulsory and you should only increase your dose if you are tolerating the medication.

Can I switch from another GLP-1 medication to Mounjaro?

Yes. Our Care Team advises that Mounjaro can be started 7 days after your last dose of another weight loss medication.

Your prescriber will agree a suitable starting dose depending on your current treatment medication and dose.

I want to pause taking Mounjaro and then resume later. How can I do this?

If you are tolerating the medication well, you can miss up to 2 doses of Mounjaro without restarting the dosing schedule.

However, if you are planning to miss more than 2 doses of your medication, you will need to recommence Mounjaro at a reduced dose to prevent severe side effects from occurring once you restart. In this case, please get in touch with our care team at hello@myjuniper.co.uk so they can arrange a review with your prescriber to amend your treatment plan.

What is the dosing schedule for Mounjaro?

The clinical recommendation of Mounjaro’s titration path is 2.5mg to 10mg and is as follows:

  1. Week 1-4 = 2.5mg weekly
  2. Week 5-8 = 5mg weekly
  3. Weeks 9-12 = 7.5mg weekly
  4. Week 13+= 10mg weekly

Higher doses are available where needed. Your Juniper prescriber will work with you to agree the appropriate higher dose for you.

How much does Mounjaro cost?

The Weight Reset Programme price will vary depending on which is your preferred medication and what your prescriber sees as safest and most effective based on your medical history.

Based on the standard titration schedule, Mounjaro through Juniper will cost:

  1. 2.5 mg = £209
  2. 5mg = £209
  3. 7.5mg = £229
  4. 10mg = £229

The clinical recommendation of Mounjaro’s titration path is 2.5mg to 10mg. Titrating higher to 12.5mg & 15mg will be an active prescriber decision in consult once a patient is stable on 10mg.

How effective is Mounjaro for weight loss?

There have been several studies on the results of Mounjaro (tirzepatide) and it outperforms other GLP-1 medications for weight loss results. According to clinical trials, tirzepatide is the most effective medication for weight loss that is available right now.

One study of over 2,500 patients from July 2022 found an average of up to 20.9% body weight loss in patients on tirzepatide after 72 weeks, compared to semaglutide (Wegovy) where average weight loss was up to 14.9% over 68 weeks.

In the same tirzepatide study, up to 90.9% of patients were able to achieve at least 5% weight loss, up to 83.5% were able to achieve at least 10% weight loss and 56.7% were able to achieve at least 20% weight loss in 72 weeks of treatment.

Do I need a prescription for Mounjaro?

Yes, Mounjaro is a prescription-only medication. This means you can't get it over the counter and instead, have to get it prescribed by an authorised healthcare professional.

Can I switch from Ozempic to Mounjaro?

While Ozempic is licensed for diabetes management, Wegovy is licensed for weight loss. Both use the same active ingredient semaglutide, which is a glucagon-like peptide-1. If you are switching from Ozempic to Mounjaro, Juniper’s Care Team Advises that Mounjaro should be started 7 days after your last dose of Ozempic, and then continued once weekly.

Can I switch from Wegovy to Mounjaro?

If you are switching from Wegovy to Mounjaro, Juniper’s Care Team advises that Mounjaro should be started 7 days after your last dose of Wegovy, and then continued once weekly.

Can I switch from Saxenda to Mounjaro?

If you are switching from Saxenda to Mounjaro, Juniper’s Care Team advises that Mounjaro can be started 7 days after your last dose of Saxenda, and then continued once weekly.

What happens if I stop taking Mounjaro?

While longer-term trials for tirzepatide are currently in progress, the SURMOUNT-4 trial found that those who switched to placebo found they experienced a 14% weight regain in 1 year. The behavioural and lifestyle changes you gain through Juniper's programme are designed to support your weight loss beyond medication alone. If you have any further questions on the use of this medicine, speak to your prescriber.

Where can I buy Mounjaro in the UK?

Mounjaro is not currently available on the NHS for weight loss. Since these are prescription-only medicines, they aren't available over the counter. Instead, a doctor or pharmacist can prescribe GLP-1/GIP treatments, which are available through private telehealth clinics, pharmacies, and GPs across the UK.
