Prescription weight loss treatments are typically designed for: 

• Adults aged 18-75 
• Those with a BMI above 30 (or a BMI above 27 and a weight-related condition such as high blood pressure or cholesterol, etc.) 
• Individuals who don’t have diabetes or pre-diabetes requiring treatment 

This list is only intended as in indicator for who might be suitable for treatment. The doctors will complete a full medical review of your consultation to determine your individual suitability for treatment.

How do weight loss treatments work? 

Understanding the science  

Our range of weight loss treatments are scientifically proven to help you lose weight, but what does that really mean? Let’s look at the main ways weight loss medications work alongside your body and not against it. 

Appetite suppression 

The active ingredients in some medications can suppress your appetite and the result is that you’ll start to feel less hungry. Those annoying food cravings? Gone! 

Feeling fuller for longer 

By slowing down how long it can take food to pass through your system, the active ingredients in some medications can help you feel fuller for longer. You’ll feel more satisfied after eating. 

Reducing fat absorption 

When food passes through your digestive system, some medications act by reducing the amount of fat that is then absorbed into the body, by as much as 25-30%. 

It’s important to remember that adopting a healthier diet & lifestyle will also play a key role in the success of your weight loss journey. Our expert team are with you at each step.  

What can you expect? 

Lose up to 22.5% of your body weight  

Clinical studies focusing on the active ingredients used in the Mounjaro (Tirzepatide) and Wegovy (Semaglutide) weight loss injections have shown consistent weight loss results of up to 22.5% and 15% respectively. These results were achieved when the medications were combined with adjustments in diet & lifestyle. 

Reduce the typical weight loss frustrations  

Weight loss medications are designed for the long-term, but you should notice changes throughout your journey and in the early stages. 

0-3 months 

The medication will start working inside your body once you take it, even if you don’t notice a difference straight away. 

• Feeling less hungry 
• Increased energy levels 
• Viewing food differently 

3-6 months 

Notice changes in your weight and lifestyle as your body works with the medication. 

• Seeing a change in your body weight 
• Feeling better in the clothes you love 
• Being more energised and active

FAQs

Explore our most-asked weight loss questions. 

What are injectable weight loss treatments? 

They are breakthrough weight loss options that have been scientifically designed to support long-term weight loss. Depending on the treatment you choose, they use a range of active ingredients (sometimes referred to Tirzepatide and Semaglutide) that stimulate naturally occurring hormonal receptors. This can help you feel fuller for longer, slow gastric emptying (how fast food travels through your system) and reduce cravings. It’s these action that can help you lose weight.  

What are oral weight loss treatments? 

They are science-backed weight loss options that have been designed to support long-term weight loss. They’re an alternative option for people who don’t want to self-inject. Depending on the treatment you choose, they can work by inhibiting enzymes in your digestive tract. This reduces the amount of fat your body can absorb from your food. It’s this action that can help you lose weight. 

Can I use weight loss treatments at the same time as other medications? 

Our range of treatments are generally considered safe to take alongside other medications, however interactions can happen and there are specific conditions and medications where weight loss treatments aren’t suitable to take. That’s why it’s important to give a full and honest answers in your online consultation.  

Will I be suitable for treatment? 

We offer a range of weight loss treatments, some of which are prescription-only medications. Each treatment has its own eligibility options. As a guide, we’d ask you to check initial eligibility against the criteria below. Meeting this is not an indicator of treatment suitability and our doctors will fully review your completed online consultation.  

• Adults aged 18-75 
• Those with a BMI above 30 (or a BMI above 27 and a weight-related condition such as high blood pressure or cholesterol, etc.) 
• Individuals who don’t have diabetes or pre-diabetes requiring treatment 

Who checks my online consultation? 

All online consultations are clinically reviewed by the doctor team. They review your answers to determine your suitability for your selected treatment. They are fully regulated in the UK and are approved to prescribe and dispense your treatment. Read more about our team. 

Will I experience any side effects from treatment? 

Each treatment comes with its own risk of side effects. Most of these are mild, and if you do experience any, most ease off in a short period of time. However, you should always explore the full list of potential side effects in the Patient Information Leaflet which comes with your selected treatment.  

How much weight could I lose? 

Weight loss varies with each person and contributing factors can include their lifestyle, their mobility and which treatment they’ve selected.  

Typical weight loss examples: 

• Mounjaro – up to 22.5% of your starting body weight 
• Wegovy – up to 15% of your starting body weight 
• Orlistat (Xenical) – more than 5% of your starting body weight 
• Mysimba – more than 5% of your starting body weight 

Should I take any supplements during treatment? 

The latest clinical guidance recommends taking a daily multivitamin to ensure you’re getting all that you need. There is a risk you might not be getting all the vitamins you need through food if you’re eating less or have changed your diet. 

Is there an ideal diet to follow during treatment? 

Whilst there isn’t a specific diet to follow, it’s recommended that you follow a healthy & balanced diet. Focus on creating balanced meals that contain adequate protein and fibre. Make sure to drink plenty of fluids too. 

Aim for 3 meals a day, with snacks in between if needed, to provide your body with steady energy throughout the day. A balanced meal should look like: 

• Filling half your plate with non-starchy vegetables, salad or fruit.  
• Filling the other half evenly between wholegrain carbohydrates and lean protein 
• Include a small serving of healthy fats within your meal 

How do I reorder my next dose? 

When it’s time to reorder, simply log in to your secure online Oxford Online Pharmacy account and select the treatment you’d like to reorder. You might need to complete a new online consultation, so we can make sure your treatment is still right for you.
