If you’ve been researching weight loss support in the UK, you’ve likely come across three standout names: Mounjaro, Wegovy, and Ozempic. These prescription medications, originally developed to treat type 2 diabetes, have rapidly gained attention for their impressive weight loss benefits. But with multiple options available, how do you know which one is right for your weight loss journey?

At Eltham Pharmacy, we specialise in providing safe, clinically supervised weight management solutions—including Mounjaro weight loss injections. In this guide, we’ll compare Mounjaro, Wegovy and Ozempic in terms of how they work, how much weight you can lose, side effects, availability, and cost—so you can make an informed decision about your treatment.

What Are These Weight Loss Injections?

All three medications belong to a class of drugs known as GLP-1 receptor agonists, which help regulate blood sugar and appetite. However, there are key differences between them:

Ozempic (semaglutide): Initially approved for managing type 2 diabetes, it mimics the GLP-1 hormone to increase insulin production and slow digestion.

Wegovy (semaglutide): Contains a higher dose of semaglutide than Ozempic and is licensed specifically for weight loss in people with obesity or weight-related conditions.

Mounjaro (tirzepatide): A newer medication that mimics both GLP-1 and GIP (another gut hormone), providing a dual-action effect that leads to even greater appetite suppression and weight loss.

How Effective Are They for Weight Loss?

All three treatments have been shown to support substantial weight loss when used alongside a healthy diet and lifestyle. Here’s how they compare:

Ozempic: Patients may lose around 5–10% of their body weight after several months of use.

Wegovy: Clinical trials show an average weight loss of 15% or more, with some patients achieving 20%.

Mounjaro: Early studies are promising. Patients in trials have reported losing up to 22% of their body weight, making mounjaro weight loss injections potentially the most effective option currently available.

The more advanced mechanism in Mounjaro means it could offer superior results, especially for those who have struggled with other medications.

Availability in the UK

Ozempic is widely available in the UK, though demand for weight loss purposes has led to some shortages.

Wegovy was launched in the UK in 2023 and is now available through specialist clinics and pharmacies, including through NHS weight management services for eligible patients.

Mounjaro received approval for use in type 2 diabetes in the UK in 2023. While it’s still being rolled out for weight loss, private clinics like Eltham Pharmacy are beginning to offer mounjaro weight loss injections under medical supervision.

If you’re seeking access Mounjaro, Eltham Pharmacy can assess your eligibility and guide you through a tailored weight loss plan that prioritises both safety and results.

Side Effects: What to Expect

As with any prescription medication, these injections may cause side effects. The most common include:

• –> Nausea

• –> Vomiting

• –> Diarrhoea or constipation

• –> Appetite changes

• –> Fatigue

Most side effects are mild and temporary, often improving as your body adjusts to the treatment. Because Mounjaro affects two gut hormones, some patients may initially notice more intense appetite suppression or gastrointestinal symptoms. However, our clinical team monitors your progress closely and adjusts your dose as needed to ensure comfort and safety.

Cost of Treatment

The cost of each treatment varies depending on where you access it and whether it’s prescribed privately or via the NHS.

Ozempic: Approx. £150–£250 per month

Wegovy: Approx. £200–£300 per month

Mounjaro: Approx. £250–£350 per month

Which Option Is Right for You?

Choosing between Mounjaro, Wegovy, and Ozempic depends on several factors, including:

• –> Your current weight and health status

• –> Medical history and risk factors

• –> Your weight loss goals

• –> Response to previous treatments

If you’re looking for the most advanced and effective option, mounjaro weight loss injections could be ideal. However, Wegovy and Ozempic remain excellent alternatives, particularly for those new to GLP-1-based therapies or with specific clinical requirements.
