Carrying excess weight can affect your blood pressure, your joints, your sleep and your risk of type 2 diabetes. For some people, medication prescribed alongside changes to diet and activity can help. It is not right for everyone, and our prescribers will tell you honestly if it is not.
A free online assessment, reviewed by a UK-registered prescriber.
Treatment is supplied only where a prescriber judges it safe and suitable for you.
Discreet plain packaging, with free tracked delivery on qualifying orders.
GPhC-registered pharmacy No. 9011198.
Every prescription follows an assessment by a registered prescriber, and treatment is one part of a plan that also involves changes to eating and activity. As a general guide, treatment may be considered if your BMI is 30 or above, or if your BMI is 27 or above and you have a weight-related condition such as type 2 diabetes, high blood pressure, raised cholesterol or obstructive sleep apnoea.
Lower BMI thresholds apply if your family background is South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean, because health risks linked to weight begin at a lower BMI in these groups.
We cannot supply treatment if you are under 18, pregnant, breastfeeding or trying to conceive. If you have a current eating disorder we will not supply treatment, and we will point you towards the right support instead.
Weight management medicines are licensed as an aid to a reduced-calorie diet and increased physical activity, not as a replacement for them. How much difference they make varies between individuals. Weight is commonly regained after treatment stops unless the changes to eating and activity carry on, which is why your prescriber will talk to you about the longer term and not only the first few weeks.
Your prescriber will also screen for the conditions that make treatment unsafe, including a personal or family history of medullary thyroid cancer, previous pancreatitis, and a number of others. If treatment is not suitable, we will tell you why and where to go next.
Not sure whether this applies to you? Start the free online assessment and a UK-registered prescriber will review your answers and tell you either way. It takes a few minutes, and there is no charge if treatment is not suitable.
Our clinicians may recommend one of the treatment options below, depending on your symptoms, medical history, and whether the treatment is appropriate for you.
Seek prompt medical attention if you experience:
Weight loss medication is surrounded by misconceptions — both overly optimistic and unnecessarily fearful. Here is what the clinical evidence shows.
No. Obesity is a long-term condition, and treatment works while it is being taken. Weight is commonly regained once treatment stops unless the changes to eating and activity are kept up, so your prescriber will discuss what happens after treatment as well as during it.
Obesity involves hormonal and neurological systems that actively resist weight loss, independent of motivation. Ghrelin, leptin resistance, and metabolic adaptation are physiological phenomena — not character flaws. Treating obesity with medication is medically equivalent to treating hypertension or diabetes with medication.
Side effects are common and are usually digestive, such as nausea or changes to bowel habit, and they often settle as the body adjusts. Serious effects are uncommon but they do happen, which is why the warning signs are listed on this page and why treatment is only supplied after a prescriber has reviewed your medical history.
For significant obesity, diet and exercise alone have a poor long-term success rate — 5-year data shows fewer than 5% of people maintain substantial weight loss through lifestyle changes alone. This is not due to failure of effort but to physiological adaptation. Medication can support sustained results that lifestyle changes alone cannot achieve.
Focus on protein and fibre at every meal
Protein is the most satiating macronutrient and preserves lean muscle mass during weight loss. Aim for 25-30g of protein per meal. Fibre-rich vegetables, legumes and wholegrains slow gastric emptying and stabilise blood sugar. Both help you feel fuller for longer, whether or not you are taking medication.
Incorporate resistance training to preserve muscle
Sleep deprivation raises ghrelin (hunger hormone) and lowers leptin (fullness hormone), directly increasing appetite and calorie intake. Poor sleep also impairs insulin sensitivity. Improving sleep quality is one of the most effective but underutilised weight management tools.
The assessment is free and takes a few minutes. A UK-registered prescriber reviews your answers and tells you whether treatment is suitable for you, and what to do next if it is not. Start your free online assessment.
You answer a set of medical questions covering your height and weight, your medical history, any medicines you take and relevant family history. A UK-registered prescriber reviews your answers and decides whether treatment is safe and suitable for you. Completing the assessment does not guarantee a prescription.
You can complete the assessment without a GP appointment, but we ask for your GP practice details and, with your consent, write to them about what has been prescribed. Keeping your GP informed is part of safe care rather than an optional extra.
With your consent, yes. We write to your GP practice so your records stay complete. If you would rather we did not, say so during the assessment and the prescriber will consider whether it is still safe to treat you.
Yes. Access Doctor is registered with the General Pharmaceutical Council (GPhC pharmacy registration #9011198). You can verify this at pharmacyregulation.org. All prescriptions are issued by GPhC-registered pharmacist independent prescribers. Medications are MHRA-approved UK-licensed products from licensed wholesalers — identical to those dispensed by NHS pharmacies.
Consultations approved before 3pm Monday–Friday are dispatched the same day via Royal Mail Tracked 24, arriving the following working day. Medication is sent in plain, unmarked packaging with no indication of contents on the exterior. Full tracking is provided from dispatch.
That is the prescriber's decision, based on your assessment, your medical history and what is clinically suitable for you. UK rules do not allow us to name or promote prescription medicines to the public, so the suitable options and their prices are shown to you once your assessment has been reviewed.
NICE criteria: BMI ≥30 kg/m² (obesity, no comorbidity required), or BMI ≥27 kg/m² with at least one weight-related condition (type 2 diabetes, high blood pressure, high cholesterol, or obstructive sleep apnoea). People of South Asian, Chinese, or other Asian heritage may qualify at BMI ≥27.5. A full clinical assessment is required before any prescription can be issued.
The prescriber will explain why and point you towards more appropriate care, which may mean speaking to your GP. If we cannot supply treatment, you are not charged for it.
The most common effects are digestive: nausea, diarrhoea, constipation and stomach discomfort. They are usually strongest when treatment starts or the dose goes up, and often ease with time. Less common but serious problems include inflammation of the pancreas and gallbladder problems, and the warning signs to act on are listed on this page. Always read the patient information leaflet that comes with your medicine.
Appetite usually returns to what it was before, and weight is commonly regained unless the changes to eating and activity continue. This is why treatment is planned alongside longer-term changes rather than as a short course.
In some cases, yes. NHS specialist weight management services and some GP practices can provide treatment, and it is free. Availability varies a lot by area and waiting times can be long, so your GP is the best person to tell you what is offered locally.
Treatments are taken in different ways, and what suits you matters, so tell the prescriber your preference during the assessment. The final decision is clinical, based on your medical history and what is safe and workable for you day to day.
Tell us during the assessment. The prescriber needs to know what you are taking, the dose, and when you last took it, so that you carry on safely at the right point instead of starting again. Be accurate about this, because a wrong dose can be harmful.
Most people notice a change in appetite within the first few weeks, while a change in weight is usually slower and builds over months. Progress varies between individuals, and treatment is reviewed as you go: if it is not working for you, continuing is not the right answer.
