Where can I buy semaglutide in the UK?

While weight loss medications have been around for years, semaglutide is a particularly exciting medical weight loss drugs thanks to its effectiveness.

So, what is there to know about semaglutide and where can you access this weight loss medication? This comprehensive guide will help you understand more about this drug, how it works and how to access a prescription. 

What is semaglutide?

Semaglutide is a weight loss and chronic weight management medication that can be used in conjunction with lifestyle interventions. This medication is the active ingredient in Ozempic, which is licensed to treat diabetes in the UK but has also previously been prescribed off-label for weight loss treatment, and Wegovy, which is used to treat obesity.

The advent of Wegovy, which was specifically developed for weight loss and weight management, means that it's no longer necessary to prescribe Ozempic for weight loss treatment.

Semaglutide is a glucagon-like peptide 1 (GLP-1) which mimics the naturally occurring hormone that works to increase insulin secretion, reduce blood sugar levels and slows down gastric emptying [1].

Where can I buy semaglutide in the UK?

Semaglutide in the form of Wegovy can be acquired through a prescription in the UK. The Juniper Programme uses Wegovy as its tool for weight management along with a carefully tailored support team to help you meet your goals. 

As of 1 September 2025, Eli Lilly, the manufacturer of Mounjaro (tirzepatide), has increased its UK list price to align with other developed countries. This nationwide change applies to providers including pharmacies, private clinics, and digital platforms.

In response, we’ve lowered the price of our Wegovy programme by 25%, and we’re making it easier for patients to switch without starting over, so that effective treatment remains within reach for as many people as possible.

So, if you've been wondering if you can switch from Mounjaro to Wegovy, the good news is that it's both safe and straightforward.

When making the switch, Juniper patients don’t need to restart at the lowest dose. If clinically appropriate, they can continue at a higher dose aligned with recent treatment history. We also only require a 7-day gap between your last Mounjaro dose and your first Wegovy dose — unlike most providers, who require 28 days.

At Juniper, we make that switch seamless and fully supported — so you can protect your progress without paying more than you need to. Our clinical switching protocol is is simple and safe:

• ‍Review — Your clinician assesses your treatment history and dose tolerance.‍
• Match — If eligible, you start on an equivalent high dose to avoid losing progress.‍
• Transition — Only a 7-day window is required between your last Mounjaro dose and your first Wegovy dose (most providers require 28 days).‍
• Support — Pharmacist check-ins, dose adjustments, and lifestyle guidance keep you on track.

Keep in mind that Wegovy isn't suitable for everyone and there are eligibility requirements for this medication.

How does it work for weight loss?

Wegovy is a once-weekly self-administered injection, which comes in a variety of strengths: 0.25mg, 0.5mg, 1.0mg, 1.7mg, and 2.4mg. Your prescriber will start you at the lowest dose of medication and you generally increase the strength over a period of weeks.

Semaglutide mimics a natural hormone produced in the body called glucagon-like peptide 1, which is produced by the digestive system after eating food and acts on the brain to regulate the feeling of fullness after meals [2]. It also helps to reduce the rate at which your stomach empties food after a meal (a.k.a gastric emptying).

The longer this process takes, the longer food remains in the stomach leaving the patient feeling fuller for longer. Therefore, they'll be consuming fewer calories during the day.

Plus, semaglutide and similar drugs have effects that extend beyond the stomach. This drug will also intervene with GLP-1 receptors that are found in the hypothalamus (an important part of the brain that regulates food intake in the central nervous system). 

Is semaglutide suitable for me?

GLP-1 medications like semaglutide (which is prescribed under the name Wegovy), is typically suitable for those who have a medical history of obesity and for those who are significantly overweight.

Typically, these medications will be prescribed if you have a BMI (body mass index) over 35 or in some cases, over 30. You can be assessed online or might need to go into a clinic face-to-face to have a conversation about starting your weight loss treatment. 

For those who might have struggled to lose weight in the past, support and medication can be the helping hand patients need to hit their weight loss goals.

What are the benefits of semaglutide?

If you think semaglutide or Wegovy only supports weight loss, you’d be surprised. This medication offers a stack of other great health benefits that aren’t only limited to losing weight. Some benefits include:

Assists the pancreas with blood sugar

Semaglutide helps the pancreas release more insulin when your blood sugar is high. This means when you eat something and your blood sugar levels rise, your pancreas responds quicker and releases more insulin to lower and improve blood sugar levels to their optimal state [3].

Helps your body regulate appetite

Semaglutide aka Wegovy works by regulating the part of the brain that controls hunger and appetite and acts in the body as a natural hormone would. If you have a dramatically reduced appetite, that will automatically put the body into a calorie deficit [4].

Helps prevent the liver from storing too much sugar and fat

When your blood sugar stays higher for longer, it causes your liver to turn it into glycogen and will store this form of sugar in the liver and the muscles. This can happen when your blood sugar falls too low or you engage in vigorous exercise.

Slows the process of food leaving the stomach

As gastric emptying slows, your digestive system breaks down food at a slower rate and your cells will be powered at a smoother and slower rate, rather than at large peaks and troughs. This also keeps you fuller for longer.

Reduces the risk of cardiovascular events

Particularly for those with type 2 diabetes, semaglutide helps lower your risk of having a stroke or a heart attack and assists with lowering your risk of suffering from conditions like sleep apnoea, heart disease and high blood pressure.

As your body weight decreases you'll generally become healthier.

Treatment for those who have exhausted all options

Semaglutide is a great option for those who feel they have exhausted all other weight loss options. When used alongside lifestyle changes, a weekly semaglutide injection can kick-start weight loss.

How do I administer semaglutide?

Many semaglutide medications, including Wegovy, are administered via an injection under the skin (subcutaneously) either around your stomach, thigh or upper arm once a week [8].

Never inject in the same site twice as you don't want to risk infection and always check the patient information leaflet that comes in the packaging with the GLP-1 pens. Try and stick to a usual injection day.

Once you start on the weekly weight loss injection, you'll be administering the lowest dose. This allows your body to adjust to the medication and lowers the chance of unwanted side effects.

Over time, you’ll increase your dose and eventually end up on a sustainable maintenance dose. The starting dose of Wegovy is 0.25mg once per week and you can move on to your next dose once your body gets used to the GLP-1 pen. Your prescriber will advise you when you can move to the next dose.

What if I miss a dose?

It is recommended you take your forgotten dose as soon as possible (within 5 days of the missed dose). However, if it's almost time for your next injection, disregard the missed shot and continue with the scheduled dosing.
