What is Mounjaro?

Mounjaro, a medication available only on prescription, has been developed to help adults in managing their weight and address issues of obesity. The main ingredient in Mounjaro is Tirzepatide, which acts as a glucagon-like peptide-1 (GLP-1) receptor agonist. This substance works by mimicking a natural hormone in our bodies that is responsible for regulating our appetite and food intake, resulting in a reduction in calorie consumption and subsequent weight loss. It is important to note that Mounjaro is not a standalone solution, but should be used in conjunction with a lower-calorie diet and increased physical activity for optimal results.

Understanding Wegovy

Similar to Mounjaro, Wegovy also harnesses the potency of GLP1s, with Semaglutide as its active ingredient. It has received approval in the US, EU and the UK, becoming one of the newest drugs in the sphere of chronic weight management solutions for adults.

Complementing a balanced diet and regular exercise, Wegovy operates by managing the individual’s appetite and food intake. This function mirrors that of Mounjaro, underpinning the similar roles both medications play in weight management. It’s critical to note that whilst both drugs share similarities in composition and function, their impacts may differ from person to person, and should not replace lifestyle changes but support them.

Comparing Efficacy

Mounjaro vs Wegovy vs Lifestyle changes

As we take a look at the effectiveness of Mounjaro and Wegovy, it’s important to remember that despite being the same class of drug, and serving the same function, the impact can differ from person to person. Research has indicated that these medications can contribute to significant weight loss over a period. The effectiveness was gauged by noting the percentage of participants who achieved a minimum of 5% weight reduction.

While Wegovy has been shown to achieve around ~15% body weight loss on average for patients, Mounjaro has shown to help its users achieve ~20% body weight loss.

However, it’s pivotal to bear in mind that the results are greatly dependent on lifestyle modifications, with diet and exercise playing a crucial role. Therefore, the maximum benefit from these medications can be achieved when they are used as part of a holistic approach to weight management that includes a healthy diet and regular physical activity. In essence, while both Mounjaro and Wegovy exhibit promising results, individual responses may vary, underlining the importance of personalised medical advice.

Dosage Differences

With Mounjaro’s active ingredient being Tirzepatide and Wegovy’s being Semaglutide, they each differ in their dosing recommendations. The commencement dose for Mounjaro is suggested at 2.5 mg administered once per week, whereas Wegovy is advised to start at a dose of 0.25 mg weekly.

Over time, the dosage of both these medications is progressively increased based on individual response and tolerance. It is of utmost importance to adhere strictly to the dosage plan outlined by your healthcare professional and avoid any self-adjustments without prior medical guidance.

This titrated dose helps avoid side effects while using the treatment.

The titration of Wegovy is from 0.25mg > 0.5mg > 1mg > 1.7mg > 2.4mg.

The tiration of Mounjaro is from 2.5mg > 5mg > 7.5mg > 10mg > 12.5mg > 15mg.

Side Effects

Just like any other medication, Mounjaro and Wegovy, whilst generally well-tolerated, do come with their own set of potential side effects. These could range from minor issues such as nausea, vomiting, diarrhoea, constipation, and discomfort in the abdominal region. Though these are common, they should not be disregarded and it’s advisable to keep your healthcare provider informed about any discomfort you may experience.

On rare occasions, patients could encounter more severe side effects. These could include pancreatitis, gallbladder disease, and even kidney injury. Whilst these side effects are not commonplace, their potential occurrence reinforces the need for close monitoring and regular check-ups with your healthcare provider throughout your weight loss journey.
