Mounjaro is a prescription-only weight loss injection containing the active ingredient tirzepatide. It is licensed in the UK for eligible adults with obesity or overweight alongside certain weight-related health conditions.
Supplied as a once-weekly, pre-filled injection pen, Mounjaro is prescribed alongside a reduced-calorie diet and
increased physical activity to support long-term weight management.
Tirzepatide is the first weight loss medicine to
activate both GLP-1 and GIP receptors, helping support appetite regulation
and sustainable weight loss.
Mounjaro works by mimicking two naturally occurring gut hormones, GLP-1 and GIP, which are released after eating to help regulate appetite, digestion and blood sugar levels. By activating these receptors, Mounjaro helps:
Together, these effects help reduce overall calorie intake, making it easier to maintain a calorie deficit and achieve sustainable weight loss alongside healthy lifestyle changes.
Mounjaro injection in the UK may be prescribed after assessing eligibility, which you can complete through our free online consultation form. It is generally prescribed for adults who meet at least one of the following criteria:
A Body Mass Index (BMI) of 30 or above, or
A BMI of 27 or above with at least one weight-related health condition, such as:
Eligibility is determined only after completion of a medical consultation and review by a UK-licensed prescriber. Always read the patient information leaflet before use.
Mounjaro begins working in the body after your first injection, but the time it takes to notice results varies from person to person. Some people experience reduced appetite and fewer food cravings within the first week, while noticeable weight loss often develops over the following weeks as the dose is gradually increased and healthy lifestyle changes are maintained.
As treatment starts with a low dose to help minimise side effects, it may take several weeks to reach the dose that is most effective for supporting your weight loss goals. Your progress will be reviewed regularly by our clinician to ensure the treatment remains appropriate for you.

Mounjaro in the UK is prescribed using a gradual dose-escalation approach, with six available strengths designed to help your body adjust over time. Treatment typically begins at a lower dose and increases every four weeks until the final maintenance dose of 15 mg is reached. Below, you’ll find the recommended Mounjaro dosing schedule, along with an overview of Mounjaro prices in the UK, which vary depending on dosages.

Mounjaro’s starting dose is 2.5 mg that gradually increases every 4 weeks until the highest dose 15mg is reached. The steady dose increase ensures that the body adjusts to the medicine well.
We provide a step-by-step video guide to walk you through the process of using the Mounjaro pen. This video covers everything you need to know, from preparing the pen to administering the dose. It’s designed to ensure you feel confident and comfortable using the pen at home.
In addition to the video guide, our clinicians will provide ongoing support to monitor any side effects or complications as you begin medication.
For optimal results and comfort, Mounjaro can be injected into either the abdomen, thigh, or upper arm. Here are some key tips for choosing the appropriate sites:
Do Not Use Mounjaro for weight loss if:
You should also speak to our clinician if you have any of the following conditions, as additional support or monitoring may be required:
Please complete our free online consultation form so our UK-licensed clinician can review your suitability for weight loss shot Mounjaro and ensure it’s the right medication for you.
Before starting Mounjaro, tell our healthcare professional about any prescription medicines, over-the-counter treatments, or supplements you use. Mounjaro may affect how some medicines are absorbed because it slows stomach emptying.
If you take oral medicines or diabetes treatments, your UK-licensed clinician can advise whether any monitoring, precautions, or adjustments are needed. Always inform our healthcare team if you start, stop, or change any medication during Mounjaro treatment.
Do not use Mounjaro during pregnancy, if you think you may be pregnant, or if you are planning to conceive, as the effects on an unborn baby are not currently known. If you are considering pregnancy, speak with our healthcare provider before starting or continuing treatment. Effective contraception is recommended while using Mounjaro to help prevent pregnancy during treatment.
Do not use Mounjaro during breastfeeding because it is not known whether tirzepatide passes into breast milk or how it may affect a breastfed baby. If you are breastfeeding or planning to breastfeed, speak with a healthcare professional before starting Mounjaro to discuss suitable options.
If you use an oral contraceptive pill and are overweight or obese, additional contraception such as condoms may be recommended. This is advised for 4 weeks after starting Mounjaro and for 4 weeks after each dose increase, as Mounjaro may affect the absorption of oral contraceptives by slowing stomach emptying.
Mounjaro is not expected to affect your ability to drive or operate machinery. However, taking it with insulin or sulfonylureas may increase the risk of low blood sugar (hypoglycaemia), which can affect concentration and reaction times.
If you experience symptoms such as dizziness, sweating, weakness, confusion, drowsiness, or increased hunger, avoid driving until they improve. Speak with a UK-licensed clinician if you need advice about using Mounjaro safely.
There is no specific Mounjaro diet you need to follow, but eating a balanced diet can help support your weight loss goals and improve treatment tolerance. Choose meals that include lean protein, high-fibre vegetables, wholegrains, fruit and healthy fats, while limiting ultra-processed foods, sugary snacks and foods high in saturated fat. Eating smaller portions and staying well hydrated may also help reduce digestive side effects.
After starting Mounjaro weight loss injection, you may notice some side effects as your body adjusts to the medication. These side effects are usually mild and go away after a short period. The most common side effects are gastrointestinal in nature and are often experienced when you first start the medication or increase the dose.
These common side effects typically occur in the early stages of treatment and usually improve as your body adjusts. If symptoms persist or worsen, consult a healthcare provider.
Pancreatitis: Severe abdominal pain with or without vomiting. If you experience this, seek emergency medical help immediately.
Gallbladder problems (cholecystitis): Sudden, sharp pain in the upper right side of your abdomen radiating to your shoulder. Seek immediate medical attention.
Anaphylaxis: Difficulty breathing, swelling of the face, lips, or tongue, and trouble swallowing. Get medical help immediately.
Diarrhoea can occur while taking Mounjaro, particularly when starting treatment or following a dose increase. Eating smaller meals, staying hydrated and avoiding foods that worsen digestive symptoms may help. Read our guide on Mounjaro and diarrhoea for possible causes and practical ways to manage it.
Mounjaro may be associated with temporary blurry vision in some people, particularly when changes in blood sugar or hydration affect eyesight during treatment. Although blurry vision is not among the most commonly reported side effects, it should not be ignored if it persists or worsens. Read our guide on Mounjaro and blurry vision for possible causes and when to seek medical advice.
Urinary changes are not generally recognised as a common side effect of Mounjaro and may have several possible causes, including changes in hydration. If you notice changes during treatment, read our guide on urinary changes while using Mounjaro for possible explanations and guidance on when to speak with a healthcare professional.
Mild stomach pain can occur as your body adjusts to Mounjaro, particularly during the first few weeks or after a dose increase. Eating smaller meals, staying well hydrated and avoiding greasy, spicy or heavy foods may help reduce digestive discomfort.
For more practical relief tips, read our guide on managing stomach pain on Mounjaro. Seek medical advice if the pain becomes severe, persistent or worsens over time.
Refer to the Patient Information Leaflet for the complete list of side effects
Mounjaro has some important safety considerations and should not be used if you are allergic to tirzepatide or any of its other ingredients.
Mounjaro Serious side effects may include:
If you have a history of gallbladder problems or have had your gallbladder removed, discuss this with our clinician before treatment. Our guide on Mounjaro after gallbladder removal explains the key safety considerations.
Swollen lymph nodes are not a commonly recognised side effect of Mounjaro and can have other causes. If you notice unusual swelling around your neck, jaw or underarms, read our guide on Mounjaro and swollen lymph nodes for possible causes and when to seek medical advice.
Mounjaro may affect how some medicines are absorbed because it slows stomach emptying. Before starting Mounjaro for weight loss, tell our healthcare professional about all medicines you take, including:
Our prescriber can advise whether any dose changes, additional monitoring, or precautions are needed.
If you take oral HRT, discuss this with our healthcare professional before starting Mounjaro. As the treatment can delay stomach emptying, it may affect the absorption of some oral medicines. Our clinician can review your HRT and advise if any changes are needed when starting Mounjaro UK treatment or adjusting your dose.
Berberine is a herbal supplement that may affect blood sugar levels. If you are taking it alongside Mounjaro, speak with our healthcare professional before combining them. Read our guide on berberine and Mounjaro for more information about potential interactions, safety considerations and using them together.
Cortisone injections can affect blood sugar levels, so tell our healthcare professional if you need one while using Mounjaro. For more information on using these treatments together, read our guide on Mounjaro and cortisone injections and the precautions to consider.
The use of Mounjaro for weight loss can vary depending on your individual health needs, weight loss goals, and how well your body responds to the treatment. For some people, long-term use of a weight loss pen may be necessary to maintain weight loss or continue managing blood sugar levels.
Long-term use may be recommended if you need continued support to maintain a healthy weight.
Discontinuing Mounjaro without maintaining a healthy lifestyle may result in weight regain. It's important to consult our clinician before stopping treatment, as they can help guide you on the ideal approach for maintaining your results.
It’s important to have regular check-ins with your UK-licensed prescriber to ensure Mounjaro is still the appropriate choice for your weight management and health goals.
Mounjaro is a once-weekly prescription weight loss treatment that can be taken at any time of the day, with or without food. To get the optimal results, it's essential to take it on a consistent schedule.
Avoid changing the day often, as doing so can affect how well the medication works.
Yes, you can move your Mounjaro injection one day earlier if at least 72 hours (three days) have passed since your previous dose. After changing your injection day, continue taking Mounjaro once weekly on the new scheduled day.
Do not take two doses within 72 hours of each other, as this may increase the risk of side effects. If you are unsure about changing your schedule, speak with our prescriber or healthcare team for guidance.
Mounjaro can be taken at any time of the day and does not need to be taken with food. The most important factor is maintaining a consistent weekly schedule by using your Mounjaro injection on the same day each week.
Choose a day that works well with your routine and consider setting a reminder. For more guidance, read about the best time to take Mounjaro. If you need to change your injection day, make sure there is at least 72 hours (3 days) between doses before starting your new schedule.
Mounjaro is increased in stages so your body can adapt gradually to tirzepatide. Starting at a lower dose and stepping up over time can help limit side effects such as nausea, vomiting or diarrhoea. Dose increases also allow your prescriber to assess how well you are responding and find the lowest suitable dose that gives effective appetite control and supports weight loss.
A small air bubble inside your Mounjaro pen is normal and does not affect the dose or effectiveness of the medication. These pens may naturally contain small amounts of air, which should not prevent the injection from working correctly.
Continue using your pen as instructed and take the full prescribed dose. If the air bubble appears unusually large or you have concerns about using your pen, speak with a UK-licensed healthcare professional for advice.
If you accidentally take more Mounjaro than your prescribed dose, contact our healthcare professional as soon as possible for advice. Using too much Mounjaro may increase the risk of side effects, including low blood sugar (hypoglycaemia), nausea, vomiting, and other digestive symptoms.
Do not take your next dose until you have received medical guidance. Our healthcare professional can advise on the correct next steps and help ensure your Mounjaro treatment continues safely.
Rapid weight loss while using Mounjaro may increase the risk of certain health concerns. Losing weight at a faster rate than recommended can affect your body in several ways, including:
Your weight loss progress should be monitored regularly. If you are losing weight faster than expected or experiencing concerns, speak with our healthcare professional for guidance.
If you miss a dose of Mounjaro UK, take it as soon as possible within 96 hours (4 days) of the missed dose. If more than 4 days have passed, skip the missed dose and resume your regular schedule with your next dose on the scheduled day.
Important:
If you need to change the day of the week you take Mounjaro, ensure you leave at least 72 hours (3 days) between your last dose and the new schedule. After that, continue taking it once a week on a new day.
A Mounjaro maintenance dose is the regular dose used after the initial dose escalation period to support continued treatment and help maintain weight management results. Common maintenance doses include 5mg, 10mg, and 15mg.
The most suitable dose depends on your response, treatment goals, and how well you tolerate the medication. Our healthcare professional will decide the appropriate dose based on your individual needs.
When you stop taking weight loss injection Mounjaro, its effects gradually wear off, and you may experience increased hunger and a return of appetite. This can lead to overeating and potential weight gain, especially if you don’t continue with healthy habits. Clinical trials show an average weight gain of 14% after discontinuing Mounjaro, highlighting the risk of regaining lost weight.
It typically takes up to 25 days for the medication to leave your system, and within 1 week, your hormones will return to their natural rhythm. While there are no typical withdrawal symptoms, some users may notice psychological changes, such as cravings or emotional impacts due to the loss of appetite control.
To avoid weight gain, it's essential to maintain balanced nutrition and regular physical activity. Consulting your healthcare provider when stopping Mounjaro will help manage these changes effectively, ensuring you can continue to maintain a healthy weight after treatment.
For most people, the common side effects of weight loss shot Mounjaro will improve or disappear within a few days or weeks as your body adjusts to the medication. However, everyone’s experience is unique, and some may find that side effects persist or return, especially when adjusting the dose.
If side effects don’t subside or worsen, it’s important to consult our prescriber to evaluate the situation.
As of now, there are no confirmed long-term side effects directly associated with taking Mounjaro, though more research is needed to fully understand its long-term impact.
To help prevent or reduce Mounjaro side effects, consider the following tips:
If side effects do occur, don’t feel the need to increase your dose immediately. Over-the-counter remedies, such as antacids or laxatives, may also provide relief.
Mounjaro injection should be stored in a refrigerator between 2°C and 8°C and kept in its original packaging to protect it from light. Do not freeze the pen or use it if it has been exposed to unsuitable temperatures. If refrigeration is unavailable, the pen can be stored at room temperature up to 30°C for a maximum of 30 days.
When travelling with Mounjaro UK treatment, protect your pens from heat, direct sunlight, and temperature changes. An insulated travel pouch can help maintain suitable conditions during journeys. Keep your medication in its original packaging with the patient information leaflet, and if travelling by air, carrying a prescription or healthcare provider letter may support smoother airport security checks.
A Mounjaro pen can be kept outside the refrigerator for up to 30 days if it is stored below 30°C and protected from direct sunlight and excessive heat. After 30 days, the pen should not be used and must be disposed of safely, even if some medication remains.
Each Mounjaro KwikPen contains four weekly doses, providing four weeks of treatment when used as prescribed. Once first used, the pen must be discarded after 30 days, even if some medicine remains. Correct storage and handling are also important for keeping the medicine suitable for use.
Read our guide to Mounjaro pen storage, expiry and safety for further guidance.
Incorrect storage may impact the quality and effectiveness of your Mounjaro injection. Do not use the pen if it has been frozen, exposed to high temperatures for a prolonged period, or left in direct sunlight or excessive heat.
If you are unsure whether your pen is still safe to use, contact your prescribing healthcare professional before taking your next dose.
| Storage situation | Recommended action |
|---|---|
| Mounjaro left unrefrigerated | It may still be suitable if stored below 30°C and within the recommended 30-day period. Seek advice if you are unsure. |
| Mounjaro exposed above 30°C | Do not use the pen if it has been exposed to excessive heat for an extended period. Speak with our healthcare provider for guidance. |
| Mounjaro accidentally frozen | Do not use the pen, as freezing may damage the medication. Contact a healthcare professional for advice. |
| Mounjaro exposed to direct sunlight or high heat | Do not use it until you have received guidance from a healthcare professional. |
After taking your Mounjaro injection, remove the used needle and place it in a sharps container. Always use a new needle for each dose to support safe and hygienic injection practices. Once the Mounjaro pen is empty, dispose of it according to local disposal guidance. This may involve placing it in a sharps container or following another approved method recommended in your area.
It is normal to feel unsure about giving yourself an injection, particularly if you have never used an injectable treatment before. Mounjaro injection comes in an easy-to-use pen device designed to make administration simple compared with traditional syringes.
The pen contains a small needle and delivers the medication automatically, making the process quick and convenient for many people. Our healthcare provider can also explain how to use the pen correctly and provide guidance when starting treatment.
A small raised area, slight redness, mild swelling, or a tiny drop of fluid on the skin after an injection can occur and is usually temporary. You may also experience mild tenderness, itching or discomfort around the injection site.
Rotating the injection area each week may help reduce irritation. For more information about local reactions, read our guide on lumps after Mounjaro injections. Seek medical advice if swelling becomes severe, pain increases or the reaction appears unusual.
Mounjaro pens include instructions on preparing and using the injection safely, including guidance on cleaning the injection area. However, alcohol swabs are not always supplied with the pen, so you may need to purchase them separately if needed.
Always follow the instructions provided with your Mounjaro injection and the advice of our healthcare professional.
Mounjaro can cause hypoglycemia (low blood sugar) when used alongside insulin, sulfonylureas, or other diabetes medications.
Before starting Mounjaro for weight loss, it’s essential to inform our clinician about all medications you’re taking, including prescribed, over-the-counter, or herbal supplements. This ensures the treatment is safe and appropriate for your health.
Wegovy: A weekly weight loss injection containing semaglutide, a GLP-1 receptor agonist. It helps regulate appetite, reduce cravings, and increase feelings of fullness.

Wegovy Pill: An oral semaglutide treatment for those who prefer a tablet option instead of an injection. It works through the GLP-1 pathway to support appetite control and weight management. Clinical trials have shown an average weight loss of around 16.6% of starting body weight after 64 weeks.

Access is generally through specialist weight management services, and eligibility depends on factors such as your BMI, weight-related health conditions and local NHS commissioning policies. Availability can vary across different areas of the UK, so speak to your GP or local NHS service to find out what options are available.
If you're looking to start treatment sooner, Mounjaro is also available through private UK clinics following a clinical assessment by a qualified prescriber.
Yes, you may be able to restart Mounjaro if you still meet the eligibility criteria and our healthcare professional considers it appropriate. The dose you restart on depends on how long you've been off treatment. If it's been more than 2 weeks since your last dose, our clinician may recommend restarting at the 2.5 mg dose to help reduce the risk of side effects. Always speak to the healthcare professional before restarting treatment to ensure it's safe and suitable for you.
Mounjaro can be taken alongside many medicines, but some medications may affect how it works or increase the risk of side effects. Because Mounjaro slows stomach emptying, it may alter how quickly certain oral medicines are absorbed. Before starting treatment, tell our clinician about all prescription medicines, over-the-counter medicines and supplements you take so they can assess whether Mounjaro is suitable for you.
Yes. Regular physical activity is encouraged while taking Mounjaro, as it can help improve weight loss results, maintain muscle mass and support your overall health. Aim for a combination of aerobic exercise and strength training alongside a balanced diet. If you're new to exercise or experience dizziness, fatigue or low blood sugar symptoms, start gradually and speak to our clinician if you have any concerns.
Mounjaro prices vary depending on the prescribed dose and provider. At London Slimming Clinic, treatment starts from £210 for a four-week supply, with higher doses priced accordingly. A clinical assessment is required before treatment can be prescribed.
Mounjaro can be stored unrefrigerated for up to 30 days, provided it is kept below 30°C and protected from direct heat and sunlight. Once stored at room temperature, it should not be returned to the refrigerator.
Weight loss may be slower if you're on a starting dose, not maintaining a calorie deficit or have only recently begun treatment. Following your prescribed dose, eating a balanced diet and staying physically active can help improve results over time.
Yes, but extra precautions are recommended. Mounjaro can reduce the effectiveness of oral contraceptives by slowing stomach emptying. Use a barrier method or a non-oral contraceptive for 4 weeks after starting treatment and after each dose increase, or speak to our clinician for advice.
No. Mounjaro is a prescription-only medicine in the UK and cannot be bought over the counter. A UK-licensed prescriber must assess your medical history and confirm that treatment is safe and appropriate before issuing a prescription.
Yes, but it should be consumed in moderation. Alcohol may worsen side effects such as nausea, vomiting and dehydration, and can increase the risk of low blood sugar, particularly in people with diabetes or those taking certain diabetes medicines.
The "golden dose" or "5th dose" refers to the small amount of liquid remaining in a Mounjaro KwikPen after the four prescribed weekly doses have been used. This residual liquid is an unmeasured buffer intended for pen priming, not an additional dose. Extracting or injecting it is not recommended, as it may result in inaccurate dosing and increase the risk of adverse effects.
Yes. Mounjaro is administered as a once-weekly injection under the skin using a pre-filled KwikPen. The needle is very short and fine, and many people report little or no discomfort during the injection.
A KwikPen is a pre-filled, multi-dose injection pen that allows you to self-administer Mounjaro. Designed for once-weekly use, it delivers accurate doses and is intended for convenient home treatment when used according to your clinician's instructions.
Not necessarily. Many people continue Mounjaro at a maintenance dose after reaching their target weight. Our clinician will decide whether to continue, reduce or stop treatment based on your progress and long-term weight management goals.
No. Although Mounjaro is effective for many people, individual results vary. Some people may experience limited weight loss or blood sugar improvements despite treatment. Factors such as genetics, underlying health conditions, medication adherence and lifestyle habits can all influence how well Mounjaro works. Regular clinical reviews help determine whether treatment remains suitable and effective.
No, Mounjaro tablets are not currently available. Mounjaro is only supplied as an injection containing tirzepatide. Foundayo is a separate oral GLP-1 treatment containing orforglipron, taken as a daily tablet, which may suit people who prefer an alternative to injections.
Mounjaro may affect the absorption of some oral medicines, including certain emergency contraception options. If you need emergency contraception while taking Mounjaro UK treatment, speak with a healthcare professional for advice on suitable options.
Mounjaro (tirzepatide) usually begins with a low weekly starting dose to help your body adjust and reduce potential digestive side effects. Our healthcare professional will gradually increase the dose based on your response, tolerance, and treatment goals.
No, weight loss medicine is not limited to women. Treatments such as Mounjaro for weight loss may be prescribed to eligible adults of any gender who meet the required health and BMI criteria. Treatment suitability is based on personal health factors, not gender.
Food noise refers to persistent thoughts, cravings, or urges around food, even when you are not physically hungry. Some people using GLP-1 treatments such as Mounjaro may experience reduced cravings and improved appetite control during their weight management journey.
Yes, maintaining good hydration is important when using GLP-1 medications such as Mounjaro and Wegovy. Drinking enough fluids supports overall health and may help with effects such as constipation or reduced appetite during treatment.
No, Ozempic and Mounjaro are different medicines. Mounjaro contains tirzepatide and is a weekly injection used for weight management. Ozempic contains semaglutide and is mainly licensed for type 2 diabetes, while semaglutide is also used for weight loss in treatments such as Wegovy.
Yes, a missed Mounjaro dose can usually be taken within 4 days of your scheduled day. If more than 4 days have passed, skip the missed dose and continue with your next injection as planned. Avoid taking two doses close together.
Most people using Mounjaro for weight loss can meet their nutritional needs through a balanced diet. If your food intake decreases, a healthcare professional may recommend supplements such as a multivitamin, vitamin B complex, or other nutrients based on your needs.
A combination of cardiovascular exercise and strength training can support weight loss while using Mounjaro. Activities such as walking, cycling, and resistance exercises can improve fitness and help maintain muscle during treatment. Choose activities suitable for your ability.
Weight loss on 10 mg Mounjaro varies between individuals and can depend on factors such as starting weight, treatment duration, diet, physical activity and your response to tirzepatide. For a closer look at dose-specific results, read our guide on 10 mg Mounjaro weight loss.
A break between Mounjaro and Wegovy may be recommended when changing treatments. The timing depends on your current dose, treatment history, and individual health factors. Our healthcare professional will advise on the safest transition approach.
Mounjaro prices may change due to factors including manufacturer updates, pharmacy costs, and supply conditions. Prices can vary between providers and doses. When comparing Mounjaro price options, consider what is included, such as consultations, prescriptions, and ongoing support.
Yes, Mounjaro treatment usually starts with the lowest dose of 2.5mg. This allows your body to adjust gradually and may help reduce side effects. Our healthcare professional will monitor your progress and increase your dose at suitable intervals based on your response and weight loss goals.
It is best to arrange your next Mounjaro supply before your current dose runs out. Ordering around two weeks in advance can help prevent treatment gaps and maintain your regular weekly dosing schedule for consistent weight management.
Some people notice reduced appetite within a few days of starting Mounjaro, while others may experience changes over several weeks. Appetite control often becomes more noticeable as your dose increases according to your treatment plan.
Mounjaro does not directly cause muscle loss, but weight loss can reduce both fat and muscle mass. Eating enough protein and including resistance exercises can help preserve muscle while supporting healthy weight loss during treatment.
There is no fixed treatment duration. Mounjaro can be used long-term if it remains safe and effective. Our clinician will regularly review your progress and decide whether to continue, adjust or stop treatment.
Many people notice a reduced appetite within 24 to 72 hours of their first Mounjaro injection. Appetite control often becomes more noticeable 3 to 5 days after each dose and typically becomes more consistent as treatment progresses.
Mounjaro does not appear to reduce fertility directly, and weight loss may improve fertility in some people. However, it can reduce the effectiveness of oral contraceptives and should not be used during pregnancy. Speak to our clinician if you're planning to conceive.
Mounjaro does not directly affect reproductive hormones, but rapid weight loss may temporarily change your menstrual cycle. Some people experience missed periods, spotting or heavier bleeding as the body adjusts to weight loss and hormonal changes.
There is no best time of day to take Mounjaro. Choose a day and time you can follow consistently each week, as regular dosing helps maintain the medicine's effectiveness and reduces the chance of missing a dose.
Weight regain is common after stopping Mounjaro because appetite and food cravings often return. Maintaining healthy eating habits, regular physical activity and ongoing clinical support can help reduce the risk of regaining lost weight.
Mounjaro is generally prescribed for adults with a BMI of 30 or above, or 27 or above with at least one weight-related health condition. A clinician will assess your eligibility based on your overall health and medical history.
The most suitable treatment depends on your medical history, weight management goals and clinical assessment. While both medicines support weight loss, our clinician will recommend the option that best matches your individual health needs.
Yes. Mental health support may be available alongside weight management, as factors such as stress, emotional eating and low mood can affect long-term success. If needed, our clinician may recommend additional psychological support as part of your personalised treatment plan.
Mounjaro is injected once a week under the skin of the abdomen, thigh or upper arm. Rotate injection sites each week and follow the instructions provided with your pen. Our clinician will explain the correct injection technique before treatment begins.
A Mounjaro KwikPen contains 4 weekly doses and typically lasts 4 weeks. Once first used or removed from refrigeration, it should be discarded after 30 days, even if some medication remains.

Yes. Effective contraception is recommended while taking Mounjaro. The medicine is not recommended during pregnancy and may reduce the effectiveness of oral contraceptives, particularly when starting treatment or after dose increases.
Breastfeeding while taking Mounjaro is not generally recommended due to limited safety data. If you are breastfeeding or planning to breastfeed, speak to our clinician about the most suitable treatment options.

Yes. Mounjaro is generally considered safe when prescribed and monitored by a qualified healthcare professional. As with any medicine, it may cause side effects and is not suitable for everyone.
After using your Mounjaro injection, remove the needle and place it in a sharps container. Use a new needle for every dose. Once the pen is empty, dispose of it safely according to local guidance, either through a sharps container or another approved disposal method where available.
Only switch weight loss medications under the guidance of a qualified healthcare professional. Our clinician will determine the safest approach, which may involve a treatment break, dose adjustment or a gradual transition depending on your current medication.
To request Mounjaro from us, follow these simple steps:
Mounjaro and Zepbound both contain tirzepatide and are manufactured by Eli Lilly, so they work through the same dual GIP and GLP-1 mechanism. The distinction lies in where they are licensed and marketed. Mounjaro is the brand available in the UK for type 2 diabetes and weight management in eligible adults, while Zepbound is the US brand approved for chronic weight management and obstructive sleep apnoea.
No, Mounjaro is not considered addictive. It works by influencing appetite-regulating hormones to help reduce cravings and increase feelings of fullness, rather than causing dependence. If you have concerns about starting or continuing Mounjaro for weight loss, speak with our healthcare provider.
Some people may still experience hunger while using Mounjaro injection. This can happen if appetite control changes over time or your current dose is no longer providing the same effect. Our healthcare professional can review your progress and advise if a dose adjustment may be appropriate.
Mounjaro can be taken with or without food, as meals do not affect how the treatment works. The key is to take your weekly Mounjaro injection on your scheduled day and follow our prescriber’s instructions.
Mounjaro does not directly burn fat. It supports weight management by targeting hormones linked to appetite control, helping reduce cravings and improve fullness. Combined with healthy lifestyle changes, Mounjaro weight loss treatment can support long-term weight management.
There is currently no generic or cheaper version of Mounjaro available. Mounjaro contains tirzepatide, while other weight loss treatments may use different active ingredients and work differently. If you are looking for more affordable options, treatments such as Wegovy may be considered after a healthcare assessment.
Non-medication approaches can support weight management through healthy lifestyle changes, including personalised nutrition, regular activity, and behaviour support. NHS or private weight management programmes and professional coaching can also help develop sustainable habits without using weight loss medication.
Your treatment includes a medical assessment, review by a UK-registered clinician, prescription approval when suitable, discreet temperature-controlled delivery, and ongoing clinical guidance. This ensures your Mounjaro injection treatment is reviewed, prescribed, and supplied safely.
No, you do not usually need to purchase needles separately. Needles and sharps bins can be included with your order if required during your assessment.
A clinical review is completed before your first prescription. Follow-up consultations are then arranged regularly to monitor your progress, review your response, and adjust your Mounjaro dose when needed.
Delivery is arranged after your consultation and approval from a UK-registered clinician. Your Mounjaro prescription is sent through a regulated pharmacy using discreet tracked packaging, and you may need to be available to receive and sign for your medication.
Yes, Mounjaro prescriptions are delivered in plain, unbranded packaging to help protect your privacy. Your medication is sent directly to your chosen address through a regulated delivery process.
The cost of Mounjaro for weight loss depends on your prescribed dose, treatment duration, and provider. Higher doses typically cost more, while private services may include consultations, prescriptions, and clinical support within the overall price.
Understanding the Mounjaro cost can help you plan your treatment budget. Some people may manage costs by remaining on a suitable lower dose when it continues to provide the desired results. Always discuss dose changes with our healthcare professional before making adjustments.
Future Mounjaro prices cannot be guaranteed. Costs depend on factors such as manufacturer pricing, pharmacy charges, and supply expenses. Any changes would depend on wider pricing decisions rather than individual clinics alone.
If Mounjaro is not affordable, speak with our healthcare provider about alternative weight loss treatments, compare available prices, or discuss whether a different suitable dose may be more manageable. Do not change your treatment without professional advice.
There is no specific Mounjaro diet required, but a balanced, reduced-calorie diet with protein, fibre-rich foods, and whole grains can support your results. Healthy eating and regular activity can also help manage side effects and improve weight management.
Most people do not need supplements if they follow a balanced diet. Supplements may be considered if a healthcare professional identifies a deficiency or reduced food intake makes it difficult to meet nutritional needs. Always seek advice before starting supplements.
Some people may qualify for Mounjaro treatment through the NHS, depending on the eligibility requirements that apply. Factors such as BMI, weight-related health conditions and NHS prescribing guidance can influence access. Those who are not eligible through the NHS can consider private treatment, subject to an assessment by an appropriate healthcare professional.
Many patients have previously relied on London Slimming Clinic for clinically reviewed, weight loss treatments. All of them consistently reported satisfaction with timely clinical support and safe delivery of their medications.
