Mounjaro Overview

Mounjaro (Tirzepatide) is a next-generation breakthrough in medical weight loss. Unlike older treatments that target just one pathway, Mounjaro works on two powerful hormones (GLP-1 and GIP) to reduce appetite, slow digestion, and stabilise blood sugar. The result? This dual approach can lead to greater weight loss than older GLP‑1‑only injections such as Wegovy in many patients.

By helping you feel fuller on smaller portions and reducing food cravings, Mounjaro supports steady, long‑term weight loss rather than quick fixes. In clinical studies, patients in clinical trials achieved around 15–22% average body weight loss over 72–88 weeks when treatment was combined with diet and lifestyle changes.

Mounjaro is about more than numbers on the scale. It helps you take back control of eating habits, it can boost energy levels, improve health markers, and restore confidence. 

Available through SwiftMedi following a secure online consultation with a UK-registered prescriber, your treatment will be dispensed from our UK-regulated pharmacy and delivered quickly and discreetly to your door.

Most adults start on 2.5 mg once weekly for four weeks. The dose is then gradually increased every 4 weeks (for example 5 mg, 7.5 mg, 10 mg, 12.5 mg, up to 15 mg) if tolerated and clinically appropriate.


Ease of use: 

The pre‑filled injection pens are designed for at‑home use, with clear, step‑by‑step instructions. Your prescriber will explain how to use the pen safely and answer any questions during your consultation

Frequently Asked Questions

Below are some of the more common questions we hear from customers about shopping with Swiftmedi.

  • Can I use Mounjaro if I don’t have diabetes?

    Yes. Mounjaro is licensed for weight loss in people without diabetes if they meet the BMI and health-risk criteria. Your prescriber will check that it is the right option and ensure it is safe alongside any other medicines.

  • How does Mounjaro help with weight loss?

    Mounjaro works by mimicking two natural hormones that reduce appetite and help control how your body handles food. This supports smaller meals and fewer cravings, making it easier to maintain a calorie deficit. Most people find it works best alongside healthy lifestyle changes.

  • Who can use Mounjaro for weight loss?

    Mounjaro is usually offered to adults with a BMI over 30, or above 27 if they have a weight-related condition such as high blood pressure or type 2 diabetes. A prescriber assesses your health, medicines and safety factors before recommending it.

  • How do I take Mounjaro and where do I inject it?

    You inject Mounjaro once a week into the skin of your tummy, thigh or upper arm. Choose a new site each week and take your dose on the same day for consistency. Consider setting a reminder on your phone where possible. Your prescriber will show you how to use the pen safely.

  • What is the starting dose of Mounjaro?

    Most people start with 2.5 mg once weekly for four weeks. The dose then increases gradually through 5 mg, 7.5 mg, 10 mg, 12.5 mg and up to 15 mg. This slow increase helps reduce side effects and allows your body to adjust.

  • Is there a cheaper alternative to Mounjaro?

    Some patients may be suitable for other GLP‑1 injections such as Wegovy or Ozempic, which also help reduce appetite and support weight loss.

  • Who should not use Mounjaro?

    Mounjaro is not suitable if you are pregnant, breastfeeding, under 18, or have certain medical conditions such as severe stomach disease or a personal or family history of thyroid cancer. A prescriber will review your medical background carefully.

  • How long does Mounjaro take to work?

    Many people notice changes in appetite within a few weeks, with weight loss building steadily over several months. Studies show significant benefit when the injections are combined with balanced meals, regular activity and good routines.

  • Can I use Mounjaro if I don’t have diabetes?

    Yes. Mounjaro is licensed for weight loss in people without diabetes if they meet the BMI and health-risk criteria. Your prescriber will check that it is the right option and ensure it is safe alongside any other medicines.

  • Do I need a specific diet while taking Mounjaro?

    You don’t need a strict diet, but eating smaller, balanced meals helps manage nausea and supports better results. Protein-rich foods and higher-fibre meals can improve comfort and keep your appetite steady during treatment.

  • Is Mounjaro safe for long-term use?

    Current evidence suggests Mounjaro is safe when used long term with proper monitoring. Your clinician reviews your progress, side effects and dose changes regularly to ensure the treatment continues to be suitable.

  • Can I drink alcohol while taking Mounjaro?

    Yes, you can drink alcohol, but it may worsen nausea or digestive symptoms, especially in the early weeks. If you have diabetes, alcohol can also increase the risk of low blood sugar, so moderation is advised.

  • What should I do if I miss a Mounjaro dose?

    If you are within four days of your usual dosing day, take the missed dose when you remember. If more than four days have passed, skip it and take your next dose on your normal day.

  • Can I use Mounjaro during pregnancy or breastfeeding?

    No. Mounjaro should not be used during pregnancy or breastfeeding, and you should stop it before trying to conceive. Your clinician can discuss safer alternatives if you are planning pregnancy.
