You could be eligible for our weight loss treatments if: 

• you are aged 18 to 75 and; 

• you have a BMI over 30 or; 

• you have a BMI over 27 and have been diagnosed with a condition that is made worse by weight gain, such as a heart condition 

However, full eligibility can only be reviewed during a full consultation with a clinician. 

Pharmacy2U offers the following weight management options: 

• weight loss injections such as Wegovy and Mounjaro 

• weight loss tablets such as Wegovy 

• non-prescription options such as alli, Orlos, and Formoline 

Every person is different, so your recommended weight loss treatment will be provided by the clinician based on your individual circumstances and clinical suitability.

Before considering any weight loss medication, it's essential to prioritise healthy lifestyle changes. Incorporating a balanced diet and regular physical activity into your routine can be effective in achieving weight loss goals. 

By adopting a balanced and nutrient-rich diet, you equip your body with the essential nutrients it needs to function optimally while curbing excess calorie intake. Think of incorporating colourful vegetables, lean proteins, whole grains, and healthy fats into your meals. 

Complementing your dietary adjustments, regular physical activity is a cornerstone in the journey towards reaching a healthy weight. Engaging in activities that elevate your heart rate, such as brisk walking, jogging, swimming, or cycling, not only burns calories but may also improves cardiovascular health. Finding enjoyable forms of exercise can make it easier to commit to a consistent routine. For instance, you might explore dance classes, yoga sessions, or even recreational sports that pique your interest, fostering a positive relationship with movement. 

However, for some individuals, additional support may be needed. There are alternative medicated treatments available (see above) that can help with weight loss, in some circumstances. These are only available after a full medical consultation with a clinician. 

A healthy weight can mean having more energy, which in turn provides motivation to incorporate regular exercise into your day-to-day routine. This helps you to maintain that healthy weight and can also support positive mental health and wellbeing. 

A BMI in the healthy range for your height, gender, and age, along with a healthy waist size, may be associated with a lower risk of conditions like high blood pressure, heart disease, and type 2 diabetes, plus day-to-day benefits like less tiredness and joint pain. 

Making positive lifestyle changes can be beneficial to prepare for side effects. You can start increasing your light activity, such as walking or stretching, and change your eating habits by consuming smaller, slower meals, foods higher in protein and fibre, and avoiding greasy or heavy meals. It’s also essential to stay well-hydrated, so be sure to have water readily available to sip throughout the day. 

The most important thing you can do is to speak to a clinician as they can help you understand if the side effects you’re experiencing are common and check over any potential severe symptoms.

Losing weight fast isn’t the goal, but reaching the targets set with your clinician in a healthy, manageable way should be. The best way to maximise the chances of achieving your goals while taking weight loss medication is to combine it with positive lifestyle changes, such as regular exercise and a healthy, well-balanced diet.

A reduced appetite doesn’t automatically mean you’ll miss out on nutrients, but it can happen if you’re eating less or choosing only very light foods. Your appetite may change, but not your body's nutritional needs, so the key is to ensure your diet includes nutrient-dense foods high in protein, fibre, and healthy fats, alongside a variety of fruits and vegetables. If you have concerns about your vitamin and nutrient intake speak to a clinician.

The NHS recommends using your Body Mass Index or BMI as one possible indicator of a healthy weight range. The BMI is a score that’s calculated based on your height, weight, and age. The score for a healthy weight, depending on these factors, sits between 18.5 and 24.9. BMI is one measure used to assess suitability, but it is not a complete assessment of health. Your clinician will consider your BMI alongside other relevant clinical information. 

To get a better picture of your weight health, the NHS advises that you should also measure your waist size. This is because excess fat in your tummy area can mean a higher risk of health conditions like heart disease, type 2 diabetes, and stroke. It’s recommended that you may need to lose weight if you’re female and your waist size is over 31.5 inches or if you’re male, 37 inches.

The prescription-only injectable medicines approved in the UK as a weight management aid are known by brand names like Wegovy (semaglutide) and Mounjaro (tirzepatide). 

Weight loss injections can aid with weight loss because they contain medicines that regulate appetite and help people feel fuller for longer. They work by mimicking naturally occurring hormones that play a role in appetite regulation. Semaglutide (Wegovy) mimics a hormone called GLP-1, while tirzepatide (Mounjaro) mimics two hormones, GLP-1 and GIP. Both slow the rate at which food moves through the gut, which can prolong feelings of fullness and reduce the urge to eat as much or as often, reducing calorie intake and encouraging weight loss.

If opting for a private treatment, the cost of weight loss injections will be set by the clinical provider who prescribes them. This cost will vary depending on the brand of weight loss injection prescribed, and the strength of the medication. 

To get an idea of costs for the prescription weight loss injections within the Pharmacy2U Online Doctor range and learn more about each treatment, you can visit our Wegovy and Mounjaro information pages. 

Some weight loss injections are available on the NHS as a weight management option for certain patients, and in these instances, the cost will be the standardised NHS prescription fee (currently £9.90 per item) unless you are exempt from paying for your NHS prescriptions.   

Whether you’re seeking treatment through the NHS or a private healthcare provider, each patient will be clinically assessed on an individual basis to determine their eligibility for weight loss injections as a treatment option. 

There is no single ‘best’ injection, or treatment of any kind, for weight loss. The most suitable weight loss treatment for you depends on your individual health profile, your BMI, and your clinician’s assessment of your consultation form.

To find the right type of weight loss support for you from Pharmacy2U, you first need to complete an online consultation at a time that suits you to let us know about you and your health profile. This will be reviewed by our expert clinicians who will consider any treatment preferences and recommend a suitable next step.  

When you stop taking your weight loss medication, the effect of the medication will gradually fade. Appetite and hunger may increase, and the feeling of fullness after eating may reduce. Gastric emptying returns to its previous rate, which can mean feeling less full after meals. 

This means the likelihood of putting the weight back on you have previously lost increases. One study from 2022 found that after 68 weeks of weight loss treatment, the average patient saw a drop of 15% in their body weight, but within one year from the end of their treatment, patients saw an average of two thirds of their prior weight loss returned. 

Some of the common and very common side effects of Mounjaro weight loss injections include: 

• Feeling sick (nausea) 

• Being sick (vomiting) 

• Diarrhoea 

• Constipation 

• Indigestion, heartburn, and reflux 

• Stomach pain 

• Low blood sugar in people with type 2 diabetes 

• Rash, itching, and eczema 

• Dizziness and tiredness 

• Bloating, burping, and excess gas 

• Hair loss 

• Injection site reactions such as itching and redness 

• Fast pulse 

• Low blood pressure 

• Gallstones 

These side effects are usually not severe. They are most common when first starting the medication but decrease over time in most patients. If you are experiencing prolonged side effects, speak to a clinician. Reducing fatty foods, eating bland food, eating smaller portions, and staying hydrated may help manage some of the side effects such as nausea, diarrhoea and vomiting. 

The rare and severe Mounjaro side effects include:  

• Allergic reaction or anaphylaxis - If you experience this, stop taking the medication and contact emergency services for immediate help 

• Pancreatitis - If you experience severe abdominal pain, with or without vomiting, stop taking the medication and contact emergency services for immediate help 

If you experience any of the serious side effects, stop using the medicine and call 999 or go to A&E immediately. 

The information provided in the side effects section is not a comprehensive list of all possible side effects associated with weight loss medication. For a complete list of side effects, please refer to the Patient Information Leaflet (PIL) provided with your medication or consult your healthcare professional.  

If you experience any side effects, including those not listed, you are encouraged to report them via the Yellow Card Scheme or contact your clinician, pharmacist, or nurse. Reporting a suspected side effect does not replace seeking medical advice or emergency help.

Mounjaro and Wegovy weight loss injections are prescription-only medicines that have been assessed by regulators for safety, quality, and effectiveness. They are not suitable for everyone and should only be used under clinical supervision. 

The safety of the medication depends on several factors, including having a consultation to ensure you're a suitable candidate, following the correct dosage schedule, and regular monitoring by a clinician. This gives you professional guidance and support should you need it, such as managing side effects or issues with your medication.  

However, the popularity of GLP-1 medications has increased, which has coincided with the increase of illegal and falsified versions of the medicine. These may be falsely advertised online and on social media. Taking unauthorised GLP-1 medication can cause serious or unexpected side effects and may interact dangerously with any other medication you’re taking.  

GLP-1 injections are only available on prescription and should only be taken under the supervision of a healthcare professional. Never buy them without a prescription or from unverified sources.  

You can take the maintenance dose agreed with your clinician for as long as it’s helping, as long as you’re not experiencing any side effects (or if any common side effects are being managed), and as long as it’s clinically safe. While using the medicine, it’s important that you keep in touch with your clinician or provider to stay on top of your progress or any issues you are having.    

If you experience an increase in weight, you should include this on your next consultation with a clinician for your repeat treatment so that they can review your dosage. If you wish to discuss stopping your maintenance dose, you should speak to your clinician, who will advise whether this is clinically appropriate for you. If so, they can work with you to develop a structured plan for stopping treatment and support you in maintaining your weight loss through longer-term lifestyle changes, including diet and physical activity.  

If you wish to restart treatment, you need to submit a consultation form. A clinician will review your full treatment and medical history to determine whether restarting medication is safe and appropriate. All prescriptions must align with current UK prescribing guidelines, which require a clinical need based on your present eligibility (e.g., BMI and health risks). Your clinician will ensure any decision prioritises your safety and long-term weight management goals.

Weight loss tablets work in different ways depending on their active ingredient.  

Semaglutide, also known as Wegovy, in tablet form is a GLP‑1 agonist, which means it mimics the GLP‑1 hormone that helps regulate appetite. Semaglutide supports weight loss by: 

• Reducing appetite 

• Helping you to feel fuller longer after meals 

There are other non-prescription weight loss tablets available that can support weight reduction, provided they are deemed suitable following a successful clinical assessment. Some of the most commonly recognised options include:  

• Orlistat 60mg (Orlos or Alli brands) - is a weight loss tablet that may be used in adults with a BMI ≥ 28kg/m2, in conjunction with a low-fat diet. Orlistat works by reducing the absorption of fat from your diet. 

• Formoline L112 – is a weight loss tablet that can bind to dietary fats in the gastrointestinal tract, effectively reducing the number of calories absorbed from fatty food. 

At Pharmacy2U, the standard cost of Wegovy tablets is as follows (pending a full and successful clinical consultation): 

• Dose level 1 – 1.5 mg - £109.99 

• Dose level 2 – 4 mg - £119.99* 

• Dose level 3 – 9 mg - £159.99* 

• Dose level 4 – 25 mg - £199.99* 

If Wegovy tablets become available on the NHS for weight loss, eligible patients may be able to access them for the standard NHS prescription charge, or free of charge for those who are exempt from prescription charges.  

The cost of non-prescription weight management aids can be found on their respective pages: Orlos, Alli, and Formoline L112. 

*Prices to be confirmed once stock is available 

The eligibility criteria for Wegovy tablets are as follows.  

Private prescribing (typical criteria):  

• A BMI of 27 or above with a weight‑related health condition (such as high blood pressure)  

• A BMI of 30 or above  

• The person is aged 18 or above 

For more information, please refer to the Patient Information Leaflet (PIL) provided with your medication or consult your healthcare professional.

Wegovy tablets may not be suitable, or may need additional clinical review, if you:  

• have kidney problems  

• are breastfeeding  

• have diabetic retinopathy  

• have low blood sugar levels (hypoglycaemia)  

• are pregnant or trying to get pregnant  

• have ever had a serious allergic reaction to semaglutide or any ingredient in Wegovy  

• have type 1 or type 2 diabetes  

• have a history of pancreatitis   

• have severe congestive heart failure  

• have gastroparesis 

• are undergoing anaesthesia or deep sedation 

You should speak to your clinician if any of the above apply to you, but also if you have any other conditions. 

For more information, please refer to the Patient Information Leaflet (PIL) provided with your medication or consult your healthcare professional.

Although Wegovy tablets and Wegovy injections contain the same active ingredient, they are taken and absorbed differently. This means dosing, instructions and suitability may differ. A clinician can advise which formulation, if any, may be appropriate for you. This can influence how well the treatment works for each person and their effects and clinical outcomes may vary. 

Wegovy tablets have been shown to be effective for weight loss when compared with a placebo (a tablet with no active medicine). In OASIS 4, the EMA reported average weight loss of 13.61% with Wegovy tablets compared with 2.18% with placebo over 64 weeks. Novo Nordisk has separately reported 16.6% mean weight loss when treatment was adhered to. Individual results vary.

Whether you’ve decided that you’d like to switch from Mounjaro to Wegovy, from Wegovy to Mounjaro, or from injections to tablets, you’ll want to know what happens next. You will need to schedule a consultation to speak with one of our clinicians, who will guide you through the process, review your medical history, and ensure that changing your weight loss medication is the right decision for you. If suitable, they will put together a transition plan for you.   

It is possible that you can switch between Mounjaro and Wegovy or injections and tablets, but it needs to be done under medical supervision. A clinician must assess current treatment, dose, timing, side effects, medical history and suitability. You should not stop, combine or switch treatments unless advised by a clinician. 

You can find our guide to switching weight loss treatments here.

A two‑month supply allows you to receive two months of your clinically approved weight loss plan from a single consultation with your clinician, subject to their review of your eligibility and suitability. 

Eligibility for a two‑month supply is based on a full clinical assessment, which includes verification of your weight and BMI, as well as ensuring you are already using a medicated weight loss service, whether with Pharmacy2U or another provider, for at least one month and are on (or due to be on) a maintenance dose. If you’ve used another provider previously, the clinician will need to verify your treatment history before approving a two‑month supply 

It is available on both Mounjaro and Wegovy, except the 7.2 mg dose of Wegovy. 

You get two of the same doses of your clinically approved weight loss plan, which equals two-month's supply, subject to a full consultation with your clinician.

The two-month supply service is only available to existing weight loss patients who have completed one full month of treatment, whether with Pharmacy2U or another provider, and are on or due to go on to a maintenance dose (as you can only request two of the same doses rather than two different doses). If you’ve used another provider previously, the clinician will need to verify your treatment history before approving a two‑month supply. 

Your clinician will solely determine whether a one or two‑month supply of your clinically approved weight loss plan is appropriate based on your treatment plan. 

Even if you are eligible and your clinician has agreed that you can order a two-month supply, if you still only wish to order one month’s supply at a time, you can continue to do so.

A two-month supply is not a clinical option for new Online Doctor patients who are not currently on a medicated weight loss plan. It may be an option for existing Pharmacy2U Online Doctor weight loss patients and patients joining Pharmacy2U directly from another medicated weight loss provider. However, if you have used another provider previously, the clinician will need to verify your treatment history before approving a two‑month supply and your eligibility is solely determined by them.
