Mounjaro mythbusting: The top five myths about the latest UK weight loss drug

Mounjaro is the latest drug to enter the UK's weight loss scene. It’s a game-changer for many struggling with weight management, promising a new approach to those seeking assistance beyond traditional methods.

However, myths have already started circulating about its effectiveness and use. This blog is here to clear away the fog, diving into what makes it stand out from other options, and tackling the questions everyone's asking.

What exactly is Mounjaro?

Known scientifically as Tirzepatide, Mounjaro has been making waves for its dual-action approach to tackling type 2 diabetes and aiding in weight loss. Approved by the FDA in the US, its clinical trials have shown impressive results, with participants seeing significant weight reductions when used alongside diet and lifestyle measures. Unlike other medications that focus on a single mechanism, Mounjaro works on two fronts, offering hope for those who've found themselves stuck or who are looking for maintenance solutions post-weight loss.


Now, let's tackle some common myths surrounding this drug and set the record straight.

1 - It offers instant results

It's important to understand that Mounjaro, like any weight loss medication, works best over time and with consistent use. It's not an instant fix but a part of a long-term health plan. It's designed to work alongside lifestyle changes, like exercise and a healthier diet, not replace them.

2 - It is a standalone solution

Mounjaro (tirzepatide), is a once-weekly non-insulin injection for adults. Patients begin with a weekly injection of 2.5 mg, gradually increasing to a maximum of 15 mg every four weeks in 2.5mg increments. This tailored approach is not a one-time solution, but rather a sustainable plan designed to adapt to each patient's unique weight loss journey in conjunction with the necessary lifestyle adjustments.

3 - It has severe side effects

hile all medications have potential side effects, Mounjaro's side effect profile is generally well-tolerated when used correctly. Additionally, Mounjaro provides the option to change the dosage if you do experience side effects so you have a lot more control over this than with other weight loss medications.

The choice of a weight-loss medication involves a nuanced decision-making process considering individual circumstances, preferences, and medical conditions. Patients are encouraged to discuss any concerns with their healthcare provider to ensure they are making the right decision.

4 - It’s a one-size-fits-all drug

The truth is, Mounjaro's effectiveness can vary from person to person. It's part of a personalised approach to weight management, considering individual health goals and conditions. The traditional dosage begins at 2.5mg and goes up to 15mg, with each dose also provided in individual pens. This allows for a broader dosing range to tailor treatment more closely to the individual's needs.

5 - It encourages dependency

The key feature that differentiates Mounjaro from other weight loss drugs is that it can be used as a tool for sustainable weight management, akin to how other chronic conditions are managed with ongoing medication, but that doesn’t encourage dependency.

For example, if someone has high blood pressure, they are put on high blood pressure medicines. When they stop taking the treatment, their blood pressure will go back up. Some individuals will have changed their diet, lost weight and started to exercise, so for a few, coming of the medication is an option, but many will need to remain on the medication. The same often happens with weight loss medication, you will have choices once you reach your target weight and Mounjaro offers a solution to this.


Mounjaro is a revolutionary product that has achieved great success internationally and is one of the safest, breakthrough weight loss medications available on the market. It stands out as a promising option in weight management, offering a new approach for those seeking support beyond traditional methods.
