What is Mounjaro
Mounjaro is a prescription medication formulated for weight loss and long-term weight management.
Active ingredient
Mounjaro contains tirzepatide, which helps regulate your appetite and blood sugar levels.
How it works
It makes you feel fuller sooner, reducing hunger and helping you eat less. It also lowers your blood sugar levels by improving your response to insulin.
Administration
Mounjaro is taken as a convenient once-weekly injection.
Suitability
Mounjaro is suitable for adults with obesity (BMI over 30) or those overweight (BMI over 27) with certain weight-related health conditions.
Effectiveness
Clinical studies have shown significant weight loss, with patients losing around 26% of their body weight in 84 weeks.
Side effects
Possible side effects include nausea, diarrhoea, vomiting, constipation, abdominal pain, reduced appetite, and indigestion.
Mounjaro can help you to manage weight effectively and achieve significant weight loss alongside a diet and exercise programme.
Mounjaro dosing schedule
Mounjaro is taken once a week. Aberdeen Weight Loss Clinic experts suggest following a schedule to gradually increase the dosage to help you get the most from your treatment.
Weeks 1–4
Start with a dose of 2.5mg once a week. This initial dose is designed to help your body gradually adjust to the medication.
Weeks 5–8
Increase the dose to 5mg, taken once weekly. This increase helps to enhance the medication's efficacy while monitoring your tolerance.
Weeks 9–12
Increase the dose again to 7.5mg once weekly. This step depends on how well you've tolerated the previous doses.
Weeks 13-16
Increase the dose to 10mg once weekly. This dose is part of the standard progression aiming for optimal weight loss.
Weeks 17+
Depending on your doctor's advice and how well you've tolerated the 10mg dose, you may increase to a maximum of 15mg once weekly.
This structured dosing schedule helps to minimise side effects and allows your body to adapt to each new dose level gradually. Always follow your healthcare provider's instructions and discuss any concerns with them to ensure the best outcomes from your treatment plan. Not all patients will need to reach the highest dose. Your dose is tailored based on your response and how you tolerate the medication. It may be that you need to increase the dose more slowly than every 4 weeks, but you must not increase the dose more quickly than that.
How to use your Mounjaro pen
Watch our step-by-step video to see how your Mounjaro pen works.
In the first week of taking Mounjaro, you may experience mild gastrointestinal side effects such as nausea, diarrhoea, vomiting, constipation, abdominal pain, indigestion, or decreased appetite. These symptoms are common as your body adjusts to the medication and often lessen over time.
Your doctor might prescribe Mounjaro for weight loss if you have a BMI of 30 or over or a BMI of 27 or over in patients with certain weight-related health conditions such as hypertension or type 2 diabetes and have not achieved adequate results from diet and exercise alone.
Mounjaro can be prescribed by a private GP for those patients who have a weight-related condition and a body mass index (BMI) of 30 or more, but in December 2024 the National Institute for Health and Care Excellence (NICE) restricted use in the NHS for patients with a BMI of at least 35.
Yes. Eligible patients across Aberdeen can be prescribed Mounjaro following an online assessment and prescriber review, with delivery to your Aberdeen address.
You administer Mounjaro as a subcutaneous injection once a week. You should use it according to the dosing schedule prescribed by your doctor.
Yes, Mounjaro pens should be stored in the refrigerator between 2°C and 8°C. However, they can be kept at room temperature for a limited period if needed, typically not exceeding 21 days. Dispose of your pen if it is frozen or kept at a temperature that exceeds 30°C.
Weight loss with Mounjaro can vary, but clinical trials have shown significant results, with some patients losing around 26% of their body weight over a treatment period, especially when combined with diet and exercise.
You may begin to see weight loss effects within a few weeks of starting Mounjaro, with more significant results occurring over several months of regular use.
Mounjaro is designed for long-term weight management. The duration of treatment will depend on your specific health goals, how well you respond to the medication, and your doctor's guidance.
Each Mounjaro pen contains four doses, enough for 28 days of weekly injections.
Mounjaro and Zepbound are both brand names for the drug tirzepatide, a GLP-1 medication. They are practically considered the same drug. Mounjaro is the brand name used and licensed for weight loss in the UK, whereas Zepbound is the brand name used in the US.
Yes, Mounjaro is available in the UK, primarily through private healthcare providers like Aberdeen Weight Loss Clinic.
Zepbound is sold under the brand name Mounjaro in the UK, primarily through private healthcare providers like Aberdeen Weight Loss Clinic.
Mounjaro can be purchased at pharmacies with a prescription from a healthcare provider. You may also find it through some online health services that offer delivery after an online consultation, such as Aberdeen Weight Loss Clinic.
Starting Mounjaro directly at higher doses, like 5mg or 10mg, is not recommended. It's started at a lower dose to minimise side effects and is gradually increased based on your tolerance. The minimum time between increases of doses for weight loss is 4 weeks.
Mounjaro has been tested and approved for use and is considered safe when used as directed under the supervision of a healthcare professional. As with any medication, there are potential side effects, so it is important to discuss these with your doctor.
Mounjaro is manufactured by Eli Lilly, a global pharmaceutical company.
Whether Mounjaro is better than Saxenda depends on your individual response to the medication, specific health needs, and other factors. Both are effective for weight loss, but the way they work and are prescribed differs. With Mounjaro, you can expect to lose around 26% of your body weight, whereas with Saxenda, you can expect to lose around 10%.
Comparing Mounjaro and Wegovy depends on your health goals, medical history, and tolerance to these medications. Both are used for weight management, but Mounjaro combines actions on GLP-1 and GIP receptors, potentially offering broader metabolic benefits. In December 2024, research by the manufacturers of tirzepatide (the active ingredient in Mounjaro) demonstrated 47% greater relative weight loss compared to Wegovy.
Yes, you can, but switching from Saxenda to Mounjaro should be done under the guidance of a healthcare provider to ensure safety and effectiveness.
