Overview

Buy Mounjaro Weight Loss Injections UK

You can buy Mounjaro weight loss injections from our UK registered online prescribing service. Mounjaro is the latest GLP1 weight loss injection available in the UK.

You will be able to order Mounjaro after completing an online assessment with our GP's. If a prescription is approved, this is passed to our pharmacy team, who prepare and post your treatment.

Wegovy is from the same family of drug, and is licensed for weight loss use in the UK. You can read our guide on how patients can switch from Wegovy to Mounjaro, if you are looking to change treatment.

What is Mounjaro?

Mounjaro is a highly effective, UK licenced weight loss treatment, shown in clinical trials to help achieve ~20% body weight loss. It is the latest GLP1 weight loss injection, and is used for people with a body mass index (BMI) over 30, or those with a BMI of 28 and a weight-related medical condition.

It contains the drug tirzepatide and is a registered trademark of Eli Lilly.

It is known as Zepbound in the US, but is launching in the UK under the brand name Mounjaro.

It is used ONCE weekly, as a subcutaneous (under the skin) injection. More information on how to inject Wegovy can be found in the Patient Information Leaflet.

Mounjaro Info Hub

How does it work?

Mounjaro contains the active ingredient tirzepatide. Tirzepatide belongs to the class of drugs called GLP-1 agonists. These drugs mimic the action of the natural GLP-1 hormone in your gut, responsible for regulating hunger and is released after a meal.

By acting similarly to GLP-1, Mounjaro helps regulate appetite, making you feel fuller and less hungry. This can lead to eating fewer calories which results in weight loss. Focusing on a reduced-calorie diet can amplify the benefits of Mounjaro.

Mounjaro also aids in preventing excess sugar from being converted into fat, thereby reducing fat storage in the body.

A full account of how Mounjaro works can be found in our guide.

Is it for me?

Mounjaro should only be used to help with weight loss if you have already tried and failed to lose weight through exercise and diet alone. Mounjaro is now available in the UK, however there are other GLP-1 drugs which are also available. These include Saxenda, Wegovy and Ozempic.

Mounjaro can be used for patients who have a BMI of over 30, or in patients with a BMI over 27, and other risk factors such as;

  • Diabetes type 2
  • High cholesterol
  • Obstructive sleep apnoea
  • High blood pressure

To read more about our UK patients experience with this treatment, you can read some of our patients Mounjaro reviews.

How effective is it?

When using Mounjaro pens to suppress appetite, you can expect to lose around 15-20% of your initial body weight after completing treatment. This is the most effective of all the released GLP-1 medications so far.

These figures have been achieved by patients who have maintained on the highest strength of Mounjaro, which is the 15mg strength.

Patients who maintain at 10mg, lose on average of 19%, while patients who maintain at 15mg, can lose around 15%.

The lower strengths of Mounjaro 2.5 and 5mg will not achieve best results. While some weight loss will be observed, the primary function of these doses is to help your body adjust to the drug without experiencing serious side effects.

Alternatives

The preferred and safest method of losing weight is via a healthy diet and increased physical exercise.

The NHS offers a 12-week weight loss plan for patients. Further information from the NHS is available for exercise and diets. Is it expected that Mounjaro will be available on the NHS, for certain patients, however this has yet to be confirmed.

Other GLP-1 drugs available in the UK as an alternative to Mounjaro include

For many people, the thought of injecting a treatment is not quite for them. There are more traditional weight loss pills available from our weight loss service, such as Orlistat. This contains 120mg of the drug, and  works by preventing 1/3rd of the fat from the food you eat from being absorbed.

You can also compare Ozempic and Mounjaro, as well as understand the differences between Wegovy and Mounjaro, by reading our helpful advice guides.
