You can buy Ozempic for weight loss online, known as Wegovy in the UK, from Simple Online Pharmacy. Ozempic itself is not licensed for use in the UK for weight loss, but is instead licensed for use for Diabetes. Both Ozempic and Wegovy contain the active ingredient Semaglutide, but Wegovy is formulated specifically for weight loss, and so is more effective.
While Ozempic only titrates to 2mg of Semaglutide, it's sister brand, Wegovy, is licensed to be used for weight loss all the way to 2.4mg. This results in more meaningful weight loss than Ozempic. Wegovy was released in mid-2023, and is exactly the same active ingredient as Ozempic. It is licensed for weight loss, and is easier to administer the recommended dosages for maximum benefit.
Saxenda is another drug from this class of medicines, and also is a GLP-1 agonist. All three drugs, contain similar active ingredients and are injected under the skin (subcutaneously) daily to help suppress appetite.
The latest and most effective of the class of drugs is Mounjaro, which helps patients achieve an average of around 20% body weight loss, vs ~14% with Ozempic.
Ozempic is an injectable medicine used to treat type 2 diabetes. It helps the body to reduce high blood sugar levels. By controlling blood sugar levels it reduces the risk of diabetic complications like heart disease and heart attacks.
It contains the active ingredient semaglutide, which is known as a GLP-1 analogue. It 's a weekly injection and the dose is gradually increased over 4 - 8 weeks until a maintenance dose is reached.
Examining how Ozempic works for weight loss leads us to the active ingredient, semaglutide. It is very similar to a natural hormone in the body called GLP-1. This hormone plays an important role in appetite control and regulation. By mimicking this hormone, semaglutide helps to regulate your appetite and make you feel fuller and less hungry. This can lead to people eating less and losing weight.
The Ozempic dosage for weight loss is typically titrated up to a maximum dose of 2mg weekly, as tolerated by each individual patient. A month should be taken at each strength, to make sure your body adjusts well to the medication. You can read more in our full guide on ozempic dosage for weight loss.
If you are already taking Ozempic for weight loss, you can make a direct dosage switch to Wegovy. For example, if you are taking 1mg of Ozempic, you can instead order Wegovy 1mg. If you are taking 2mg of Ozempic, you can move up to the 2.4mg Wegovy dose. Just complete our online assessment, and provide our prescribers with all information of your Ozempic history. Our GPs can then help you switch over to Wegovy safely. As it's the same drug, you shouldn't notice any new side effects, unless you are increasing your dose.
Ozempic is a fully approved and licensed medicine in the UK. However, it 's only been approved as a treatment for type 2 diabetes and isn 't currently licensed as a weight-loss treatment. You may find certain private weight loss clinics prescribing it and this is legal but it's known as 'off-label' prescribing. This is when a medicine is prescribed outside the scope of its licence.
If you do buy Ozempic online, you should make sure that the website you are buying from is a UK registered and regulated online pharmacy.

The side effects below are taken from the Ozempic patient information leaflet. This leaflet has been produced for people taking Ozempic for type 2 diabetes treatment. The information may not be correct for people using Ozempic for weight loss through a private clinic because the doses used may differ.
Two very common side effects are nausea and diarrhoea. These are thought to affect more than 1 in 10 people using this medicine. These side effects usually improve after using this medicine for some time.
An uncommon but serious side effect is an inflamed pancreas (acute pancreatitis). This can cause severe pain in the stomach and back which doesn 't go away. Anyone with signs of this side effect should seek medical attention.
Other side effects include vomiting, stomach bloating, tiredness, reduced appetite, and acid reflux. There is also much discussion about "Ozempic Face", and how you can avoid the gaunt appearance of rapid weight loss.
You can read more in our guide on how to manage ozempic side effects.
Ozempic is available on the NHS for the treatment of type 2 diabetes. It is not currently offered by the NHS as a weight loss medication. Ozempic is only available for weight loss on private prescriptions from private weight loss clinics. Each private clinic will set its own Ozempic cost to their patients. Buying Ozempic from a UK registered online clinic is legal, however costs can vary dramatically. You should also be satisfied that the care and advice you are receiving will allow you to get the full benefit of the treatment.
The weight-loss treatment orlistat is available on the NHS and it can also be bought from your local pharmacy.

Ozempic is not suitable for everyone. It should not be taken by anyone who’s allergic to semaglutide or any of the other ingredients. Pregnant and breastfeeding women should not take this medicine.
Studies have shown that the family of medicines that semaglutide belongs to (GLP-1 analogues) can cause thyroid tumors in rats. There is very little data about this effect on humans, but the risk cannot be excluded.
For more information on the warnings associated with this medicine, see section 2 of the patient information leaflet.
