Mounjaro is a new weight loss drug authorised for weight loss and management in the UK. Initially a type 2 diabetes treatment, it contains the active ingredient Tirzepatide. When taking Mounjaro for weight loss, patients use one Mounjaro pen per week and must follow a diet and exercise plan for best results.
Mounjaro is a weekly weight loss injection that contains the active ingredient Tirezepatide, which imitates two hormones: glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). These hormones slow digestion, so food takes longer to pass through your digestive system. They also reduce your appetite, so you feel fuller for longer and eat less.
Mounjaro weight loss injections are suitable for those who meet the following Mounjaro BMI requirements:
If you have any of the following conditions, talk to your GP or pharmacist before using Mounjaro:
If you use a sulphonylurea (diabetes medicine) or insulin, be aware low blood sugar (hypoglycaemia) can occur. Your doctor or pharmacist may need to change your dose of these other medicines to reduce this risk.
Mounjaro injections for weight loss come in different dose options. The starting dose of Mounjaro is 2.5mg, and if appropriate, you’ll move up to 5mg after 4 weeks. Once you have settled on 5mg, we will work with you to decide if you need to increase to a higher dose of 7.5mg, 10mg, 12.5mg or 15mg. Each time your dose increases, you need to remain on it for 4 weeks before increasing.
Mounjaro injection pens vary in price depending on where you purchase them. At Click2Pharmacy, we aim to make weight loss treatment as accessible as possible and are committed to fair pricing.

Clinical studies have shown that Mounjaro can lead to a 15% weight loss in patients after 9 months of taking it for weight loss.
When announcing the authorisation of Mounjaro pens for weight loss management in the UK, the MHRA shared clinical trial results over 16 months showing up to 22.5% weight loss in patients taking Tirzapatide.
Mounjaro starts working immediately, but initial weight loss in the first month is often small as your body adjusts to the medication. This is completely normal and part of the process.
Studies show that you may lose up to 4% of your body weight during the first 4 weeks, with further weight loss up to 72 weeks. For healthy weight loss, Mounjaro should be combined with a reduced-calorie diet and regular physical activity. As you continue treatment, you’ll likely see more consistent progress over time.
Mounjaro should be injected under the skin (subcutaneously) in your abdomen, thigh, or upper arm. Use a new injection site each week to avoid irritation. If you use the same limb or your abdomen, use a different spot within the same area.
If you’re unsure how to inject or need guidance, check the Mounjaro Instructions For Use included with your pen or reach out to your doctor or pharmacist for help.
Mounjaro weight loss injections should be injected under the skin of your stomach, upper leg or upper arm:
A completely stuck Mounjaro pen is quite rare, and what many people experience as “jamming” is actually the pen’s built-in safety mechanism doing its job.
If your pen feels resistant, this is often normal and part of the design that ensures safe, precise dosing. However, if you have problems with your pen, there are several simple checks you can perform yourself to fix a jammed Mounjaro pen and resolve the problem.
Like any other medication, you may experience side effects from taking Mounjaro, and everyone’s experience differs. If you are concerned about any side effects of Mounjaro weight loss injections, speak to your pharmacist or GP before starting treatment.
Mild stomach issues from taking Mounjaro injections for weight loss usually improve in time. If you experience nausea, users have found the following has helped:
If nausea continues after following these guidelines, speak to your doctor or pharmacist.
If you have a kidney-related health condition and experience diarrhoea, nausea or vomiting after using Mounjaro, ensure you increase your fluid intake to reduce the risk of dehydration and contact your GP, pharmacist or an out-of-hours doctor.
These are not all the possible side effects of Mounjaro. You should review the Patient Information Leaflet before starting the treatment so you are familiar with all potential side effects.
If you experience any side effects, even if they aren’t included in the patient information leaflet, report them to your doctor, pharmacist or nurse. You can also report side effects directly via the Yellow Card Scheme.
If you’re exploring treatment options for weight management or type 2 diabetes, there are several proven medications available instead of Mounjaro.
At our weight loss clinic, we understand that finding the right medication is a personal journey, which is why we offer trusted options like Wegovy and Saxenda.
If you’re wondering about the differences between these medications:
If you are looking for alternatives to using weight loss injections, you might be interested in weight loss pills such as Orlistat, Alli Weight Loss Capsules or Xenical Capsules.
Mounjaro is a prescription-only medication in the UK, but getting started is easy with our online weight loss clinic. Simply complete a quick consultation form to begin the process of buying Mounjaro online.
If needed, our pharmacist will then arrange a full consultation to ensure Mounjaro is the right weight loss medication for you. Once approved, your prescription will be delivered straight to your door.
As part of the consultation process, we’ll need a full-length, clothed photo to visually confirm that you meet the Mounjaro BMI requirements. This helps us ensure that Mounjaro is safe and appropriate for you.
No, you won’t need to upload photos for every reorder. Once your prescription is approved, you’ll only need to provide new photos if your medical details change or if we request them during a follow-up weight loss consultation.
If you’ve ordered Mounjaro from Click2Pharmacy before, we’ll send you a reminder email when it’s time to reorder. It’s a good idea to reorder your next dose at least one week before your current pen runs out. This ensures there’s enough time for processing and delivery so you don’t miss a dose.
Mounjaro can be used for weight loss even if you don’t have diabetes. The Mounjaro BMI requirements for adults are a BMI of 30 or higher, or 27 or higher if you have weight-related health conditions like high blood pressure or sleep apnea. Our online weight loss clinic makes checking your eligibility and getting started simple.
While Mounjaro isn’t officially approved to treat PCOS, it could help with some common symptoms like insulin resistance and weight management. By improving blood sugar levels and supporting weight loss, it might make managing PCOS a bit easier. If you’re thinking about trying Mounjaro for PCOS, it’s a good idea to chat with your doctor or pharmacist to see if it’s right for you.
You will start with 2.5 mg once a week for the first month and then, if appropriate, move up to 5 mg. Your provider may adjust your dose gradually to help you get the best results, with a maximum dose of 15 mg per week. The right dose of Mounjaro depends on what works best for your body.
Typically, you’ll start at the lowest dose (2.5 mg) for the first four weeks, then move to 5 mg. If needed, your dose may be increased gradually every four weeks, depending on how well your body responds and tolerates the treatment. When you reorder your prescription, we will run you through a short consultation form and work out the best next steps for your weight loss journey.
Weight loss can vary from person to person, and it’s normal for progress to slow down at times. This is known as a weight loss plateau.
Factors like diet, exercise, and how your body responds to Mounjaro all contribute to how much weight you will lose. Stay consistent with your treatment plan, and if you’re concerned, speak with your doctor or pharmacist so they can help adjust your plan to keep you on track.
Mounjaro pens contain four doses, so you will use the same pen for multiple weeks. However, you’ll need to attach a new needle for each injection to ensure safety and proper use. Once all four doses are used, the pen should be safely discarded as directed.
Mounjaro pens come with needles specifically designed for use with the pen. However, needles can sometimes become bent, broken, or blocked, so it’s always a good idea to have spare compatible needles. Remember to use a new needle for each injection for safety and to ensure the pen works properly.
Most people find Mounjaro injections to be relatively painless. You might feel a slight pinch or sting during the injection, but this usually goes away quickly. To make the experience more comfortable, choose a clean, soft injection site and follow the instructions provided.
If the pen isn’t held in place long enough after the injection, a small amount of leakage can occur at the injection site. To avoid this, hold the pen firmly in place for up to 5 seconds until see the 0 icon in the dosage window. If leakage continues or you’re unsure about proper injection technique, contact your doctor or pharmacist for guidance.
Mounjaro can be injected at any time of the day, whatever works best for you. The most important thing is to take it on the same day each week to keep your schedule consistent. If you need to change your dosing day, make sure there are at least three days between injections.
If you miss a dose, don’t worry; you can take it as long as it’s within 4 days of your scheduled injection. After that, just skip the missed dose and continue with your regular schedule. Never take two doses too close together. If you’re unsure what to do, your doctor or pharmacist can help guide you.
It’s normal for a little bit of medication to be left in the pen after you’ve used all four doses. This is part of the design to make sure each dose you take is accurate and complete. Don’t try to use what’s left – just follow the instructions to safely throw the pen away.
If you accidentally take an extra dose, contact your doctor or pharmacist right away. Taking too much Mounjaro can increase the risk of side effects like nausea or low blood sugar.
Switching medications should always be done with your doctor’s or pharmacist’s guidance. They’ll help you transition safely and choose the best alternative for your weight-loss goals.
Don’t stop taking Mounjaro or start a new medication without consulting your healthcare provider to avoid unwanted side effects or gaps in treatment.
Mounjaro may be available on the NHS for treating Type 2 diabetes in certain cases, but it is not widely offered for weight loss. If you’re not eligible through the NHS, Mounjaro is available to buy online through our weight loss clinic, subject to eligibility. Complete a quick consultation to see if it’s the right option for you.
Mounjaro works effectively as a long-term solution for managing Type 2 diabetes and achieving sustainable weight loss.
Once you reach a point where you no longer want to lose weight, it’s important to talk to your GP or pharmacist about the next steps. They can guide you on how to gradually adjust to a maintenance dose of Mounjaro or stop the medication altogether.
Yes, you can take your Mounjaro pen abroad, but it’s important to store it correctly. Mounjaro must stay refrigerated (2°C–8°C) until you take your first dose. After that, the pen can be stored at room temperature (below 30°C) for up to 30 days.
Always carry it in its original packaging along with a copy of your prescription, and check the rules for carrying medication in your destination country before you travel.
Mounjaro can make a real difference for you if you’re managing diabetes or working to lose weight. It helps balance your blood sugar and reduces those tough cravings that can get in the way of your goals. With just one injection a week, it’s designed to fit effortlessly into your life, so you can focus on feeling your best and achieving your health journey with confidence.
