      About Mounjaro®

      On this page

      What is Mounjaro®?

      Mounjaro® is a weekly injection to help people with high BMIs (body mass indexes) lose weight. It contains the active ingredient tirzepatide.

      Is Mounjaro® available in the UK?

      Mounjaro® has recently been approved as a weight loss treatment in the UK. It will be available at some point in 2024 on prescription. Please check the LloydsPharmacy Online Doctor website for updates.

      How does Mounjaro® work?

      The active ingredient, tirzepatide, activates two hormonal receptors (GIP and GLP-1). When these naturally occurring hormones are mimicked, your appetite is suppressed, blood sugar is better regulated and the rate at which food leaves the stomach is reduced. All of these actions result in weight loss. 

      How effective is Mounjaro®?

      Clinical trials have shown that  on average, patients lost up to 21% of their original weight on the highest dose of Mounjaro® (15mg). Most adults (96%) can also expect to lose at least 5% of their body weight when using Mounjaro®.

      Who can take Mounjaro®?

      • Adults with a BMI of 30 or above
      • Adults with a BMI of 27 or above with weight related health problems, such as a history of heart attack, stroke, or breathing problems during sleep 

      Is Wegovy® the same as Mounjaro®?

      Wegovy® and Mounjaro® are both approved weight loss treatments for adults with a BMI of 30 or above, or 27 and above with a weight related condition.

      They work in a similar way, but Mounjaro® is reported to be more effective; on the highest dose.

      Mounjaro® mimics GLP-1 and GIP. Wegovy® mimics only GLP-1. 

      Taking Mounjaro® 

      You inject Mounjaro® once a week into your tummy, thigh or upper arm. Mounjaro® comes in several doses. Depending on where you are in your treatment journey, you will need to take a different dose.

      The starting dose is 2.5mg. This increases in increments of 2.5mg until you reach 15mg. The dose is gradually increased to make sure you can cope with any side effects. You will need to stay on each dose for four weeks before you increase it.

      If all goes to plan and you can tolerate the treatment, your dosing schedule will look like this:

      • Weeks 1-4: 2.5mg weekly
      • Weeks 5-8: 5mg weekly
      • Weeks 9-12: 7.5mg weekly
      • Weeks 13-16: 10mg weekly
      • Weeks 17 onwards: 15mg 

      Mounjaro® potential side effects

      Like with all medications, some people will experience side effects. Very common side effects include:

      • Feeling sick (nausea) and being sick (vomiting)
      • Diarrhoea
      • Constipation

      Using our Mounjaro® service  

      If you’d like to request Mounjaro® for weight loss, please complete our weight loss consultation. The consultation will ask you a series of questions to assess if the treatment is right for you.

      If it’s your first-time ordering Mounjaro® from us, you’ll need to upload a video showing your ID and weight, so we can verify your identity and BMI. If you’re prescribed, you can have your treatment delivered the next day.

      We will not be able to deliver Mounjaro® to Northern Ireland, and other exception postcodes in the UK, as the treatment requires cold storage (2-8 degress Celsius) during transportation. We cannot guarantee no disruption to cold storage when delivering to these areas. 

      How will Online Doctor support you while taking Mounjaro®

      If you’re taking Mounjaro®, our clinicians will support you through your journey in a variety of different ways:

      1. As part of your ongoing support from our clinical team, we’ll send you a follow up questionnaire after you’ve been taking the treatment for around one week, to see how you’re getting on.
      2. We have a range of healthy lifestyle advice and wellbeing resources to support you on your weight loss journey. The included nutritional assessment offers information on national dietary guidelines and main food groups to help you improve your overall health.
      3. We’ll remind you when it’s time to reorder, so you don’t miss out on treatment.    

      At certain intervals, you’ll be asked to update our clinicians on your weight to make sure the treatment is still suitable.

      If you have any questions or queries you can send our team a message in your Patient Record.   

      Storing and throwing away your Mounjaro® pens

      Cold storage during delivery

      • We use packaging that keeps your treatment at the right temperature for up to 36 hours during transit.
      • If cold storage is disrupted during the delivery process, the medication will be able to be used for up to 30 days.
      • Once you have received your medication it is important you keep it stored in the fridge.

      How to store

      • Any Mounjaro® pens that haven’t been opened should be kept in the fridge. 
      • During use, you can keep the pens for 30 days in the fridge or at room temperature (below 30°C).

      How to throw away

      • Pens need to be disposed of in the sharps bin you’re given when you start your treatment.
      • When you're prescribed Mounjaro® we’ll let you know how to get rid of the sharps bin and its contents. 

      Alternative weight loss treatments

      There are weight loss treatments available in the UK, other than Wegovy®. We recommend that you speak to a clinician to find out what is right for you.

      Other weight loss treatments include:

      The NHS has helpful weight loss diets and exercise routines which can support you on your weight loss journey alongside a medicated treatment.
