Losing weight is not always easy, especially when diet and exercise don’t give the results you want. For many people struggling with obesity or weight-related health issues, weight loss injections have become a modern solution. But with some of the best options now available in the UK, like Wegovy and Mounjaro, how do you know which is the best?
In this article, we’ll compare the best weight loss injections, how they work, who they’re for, and which one might be right for you.
What Are Weight Loss Injections?
Weight loss injections are prescription-only medicines designed to help people lose weight in a safe and controlled way. They work by mimicking certain hormones that regulate hunger, making you feel full sooner and eat less. These injections are usually given once a week and are meant to be used alongside a healthy diet, and regular exercise.
Two of the most talked-about names in the UK right now are Wegovy, and Mounjaro.
Wegovy Weight Loss Injection
Wegovy contains a medicine called semaglutide. It works by copying a natural hormone called GLP-1, which helps control appetite. It slows down how quickly food leaves your stomach, so you feel full for longer.
Wegovy is approved in the UK for people with a BMI of 30 or more or 27 and above if they have weight-related conditions like high blood pressure or type 2 diabetes.
Pros:
- Backed by strong clinical studies
- Easy weekly injection
- Helps reduce appetite and food cravings
Things to Know:
- Can cause side effects like nausea, bloating, or tiredness
- Should be prescribed by a qualified healthcare professional
- It may take several weeks to see full results.
Mounjaro Weight Loss Injection
Mounjaro, another name making headlines, contains tirzepatide. Unlike Wegovy, it mimics two hormones – GLP-1 and GIP. This double action may offer even greater weight loss benefits than Wegovy.
Mounjaro is currently approved for managing type 2 diabetes in the UK, but it’s also being used off-label for weight loss under medical supervision.
Pros:
- May lead to more weight loss compared to other injections
- Targets multiple appetite-controlling hormones
- Encouraging early results from users and studies
Things to Know:
- Not officially approved for weight loss yet (in the UK), so access may be limited.
- Side effects can include nausea, diarrhoea, or fatigue.

Are Weight Loss Injections Safe?
Yes, when prescribed by our pharmacist, weight loss injections are generally safe. However, like any medicine, they can have side effects and aren’t suitable for everyone. These injections should always be part of a full weight management plan, including healthy eating, exercise, and medical guidance.
