Buy Ozempic Online | What is Ozempic (Semaglutide) Injection?
Buy Ozempic Online – Semaglutide injections are prescribed to patients who suffer from Type 2 Diabetes to help them treat and manage their condition. A side effect of Semaglutide appears to be weight loss, with many users of this medication experiencing reduced appetite and a significant reduction in baseline weight since starting their treatment. Semaglutide’s effectiveness as a weight-loss drug is still being tested, however, we expect to see it being released as a new form of weight loss medication within the next 5 years.

Who is Semaglutide (Ozempic) for?
At the moment, Semaglutide is only licensed for use in patients with Type 2 Diabetes who haven’t been able to manage their blood glucose levels with diet and exercise alone. The first choice of medicine to treat Diabetes would usually be Metformin, however, some people are unable to take this. If oral Antidiabetics or Insulin are not enough to control your condition, then Semaglutide (Ozempic) is suitable, as it can be in conjunction with other treatments. It’s important to be aware that Semaglutide isn’t currently licensed for weight loss, although it’s likely to be in the near future. This medication could be prescribed off-label, however only in cases where a doctor thinks you would be a suitable candidate. This is up to the discretion of each individual doctor. Currently, the Semaglutide patient information leaflet states that if you have any of the following conditions, you should either avoid the medication or speak to your own GP before using the weekly injection:
Ozempic Weight Loss Injection
- Allergic to any of the ingredients in the semaglutide injection
- Type 1 diabetes
- Diabetic ketoacidosis
- Kidney problems
- Dehydration
- Pancreatitis
- Hypoglycaemia
- Diabetic eye disease
- Pregnant
- Breast feeding
In addition to these, you should also speak to your GP if you’re using any other medicines which can be used to treat diabetes such as Metformin or Insulin, and if you’re using blood thinners such as Warfarin.

What is the Difference Between Semaglutide and Ozempic?
Semaglutide is a pharmaceutical drug developed by the Danish company Novo Nordisk. It is used to treat and help manage Type 2 Diabetes by improving the body’s ability to lower blood sugar. Chemically, Semaglutide is similar to the naturally occurring hormone glucagon-like peptide-1 (GLP-1) which has the ability to decrease blood sugar levels in a glucose-dependent manner by enhancing the secretion of insulin. This medication is primarily prescribed to sufferers of Type 2 Diabetes when the use of Metformin is unsuitable. Ozempic is simply the trade or brand name for the Type 2 Diabetes drug Semaglutide. There are no significant differences between Ozempic and Semaglutide (other than their names), as they are essentially the same drug. Both Ozempic and Semaglutide contain the same active ingredient, Semaglutide, which is a GLP-1 receptor agonist. This medication (under the name of both Semaglutide and Ozempic) has been proven to be an effective treatment for Type 2 Diabetes and has also recently been shown to be an effective weight loss treatment for people with high BMIs. However, trials are still being carried out on the drug, meaning it has not yet been approved as a form of weight loss medication.

How does Semaglutide (Ozempic) Help with Weight Loss?
Whilst the drug has been manufactured for Diabetes, the active ingredient (Semaglutide) appears to suppress patients’ appetites and help them to feel more satisfied after a meal. This means that those using Semaglutide are more likely to consume fewer calories as they feel more satisfied after a meal and are therefore less likely to snack as much between meals. This reduction in appetite may also contribute to patients eating smaller portions than what they’re used to. As a result, those using Semaglutide are more likely to consume fewer calories than they usually would (before taking the medication). This tends to result in patients beginning to lose weight rather than maintaining their current weight when they start taking Semaglutide.

How Effective is Semaglutide (Ozempic) for Weight Loss?
957 participants with a BMI of 30 kg/m2 or more took part in a clinical trial to test the efficacy of Semaglutide as weight loss drug. Eligible participants were adults over the age of 18 years, who did not have diabetes. The results found that in 37-65% of participants receiving Semaglutide injections, their weight was reduced by an estimated loss of 10% or more. However, in those taking the placebo, only 10% of participants had an estimated weight loss of 10% or more. This study, therefore, concluded that Semaglutide (at all doses) results in clinically relevant weight loss compared to that of the placebo.
Can I use Semaglutide (Ozempic) for Weight Loss Now?
Semaglutide is not currently licensed for weight loss. It is only currently recommended for use by people with Type 2 Diabetes. However, the drug is likely to be approved as a weight loss drug in the near future and tends to be well-tolerated by people who do not have Type 2 Diabetes, with no new safety concerns arising in recent trials. It has been known for this medication to be prescribed off-label, however only in cases where the doctor believes that the patient is a suitable candidate for the drug and no contradictions is present. This decision is entirely up to the discretion of each individual doctor.
Ozempic Weight Loss Injection

Wegovy is available in 5 different doses. It is self-injected once a week, and everyone needs to begin Wegovy treatment on the starting dose of 0.25 mg once a week for four weeks.
Can I switch from Ozempic to Wegovy?
If you have already been taking Ozempic, then you should be able to switch to Wegovy by taking the equivalent dose. That’s because Ozempic and Wegovy contain the same active ingredients.
For example, if you are currently taking 1 mg of Ozempic per week, you can switch to a weekly 1 mg dose of Wegovy. However, you must do this under the guidance of a clinician.
If you want to switch from Ozempic to Wegovy, complete a short online health consultation, providing our clinicians with all the relevant information about your Ozempic history. Our clinicians can then help you safely switch from Ozempic to Wegovy.
If you are switching to an equivalent dose, you should not experience any new side effects.

Is Ozempic legal in the UK?
Yes, Ozempic is legal in the UK; however, it is not licensed for weight loss, but rather for the treatment of type 2 diabetes. Some private weight loss clinics may prescribe Ozempic ‘off label’, where medication is prescribed outside the scope of its licence. Although this is legal, it can lead to shortages of the medication for those who need it. Instead, Wegovy is a licensed semaglutide-containing weight loss medication administered as an injection.

Where can I buy Ozempic?
Can I buy Ozempic online for weight loss?
No, but Wegovy is available online for weight loss. Ozempic may be available from some online services for weight loss, but it will be prescribed ‘off-label’. The Wegovy dose, however, has been specifically formulated for weight loss, so you can expect to achieve better weight loss results with Wegovy.
Can you buy Ozempic over the counter?
No, Ozempic is not available over-the-counter. Alli is an over-the-counter weight loss tablet that’s available from most UK pharmacies and online without a prescription.
Is Ozempic available on the NHS?
Ozempic is available on the NHS for the treatment of type 2 diabetes; however, it is not approved for weight loss. Ozempic may be available on private prescription from some weight loss clinics. However, Wegovy is an alternative weight loss injection that has been approved for weight loss in the UK and is available on the NHS, containing the same active ingredient as Ozempic. Orlistat is also available on the NHS for weight loss.
Ozempic side effects
Ozempic side effects are similar to Wegovy’s because they contain the same active ingredient.
Very common Ozempic side effects include:
- feeling sick
- diarrhoea
- low blood sugar
Common Ozempic side effects are: being sick,
- low blood sugar
- indigestion
- gastritis
- stomach pain
- bloating
- burping
- gallstones
- dizziness
- tiredness
- gas
Ozempic side effects are usually worse when you first start the medication or when you increase the dose, but they should subside as your body gets used to semaglutide. However, severe side effects like an inflamed pancreas or an allergic reaction will require immediate medical attention.
Ozempic alternatives
Although Ozempic is not licensed for weight loss in the UK, there are several weight loss injections that are.
Wegovy is the closest weight loss injection to Ozempic because it contains the same active ingredient, semaglutide. That means Ozempic and Wegovy work in exactly the same way, except Wegovy contains a different dose, formulated to support weight loss. At Prescription Doctor, Wegovy prices start from £139.99.
Mounjaro is another weight loss injection which contains the active ingredient, tirzepatide. It is a dual-action medication because it acts as both a GLP-1 receptor agonist and a GIP receptor agonist, thereby mimicking two hormones that play a crucial role in regulating appetite. Research shows that at the highest maintenance dose of 15 mg per week, Mounjaro can help people lose up to 22.5% of their body weight over 72 weeks. Mounjaro prices start from £159.99 at Prescription Doctor.
Weight loss pills are also available as an alternative to weight loss injections, such as Wegovy and Mounjaro, if they are not suitable for you. Currently, orlistat (Xenical) is available to buy online and may be available from the NHS. It works by binding to the fat you eat and stopping it from being absorbed by your body. An over-the-counter version, Alli, is also available without a prescription. We also offer MySimba, which works by regulating your appetite.
Summary
Semaglutide is a GLP-1 receptor agonist that is licensed for weight loss in the UK under the brand name Wegovy. Ozempic is licensed for treating type 2 diabetes and lowering high blood sugar levels, not weight loss. However, some private weight loss clinics and other online services may offer Ozempic ‘off-label’. Although this is perfectly legal, it can lead to Ozempic shortages, and because Ozempic is available at a lower dose than Wegovy, it may result in less meaningful weight loss.
