What Is Wegovy (Semaglutide)?

Wegovy is a brand-name prescription medicine containing semaglutide 2.4mg, manufactured by Novo Nordisk. It is licensed in the UK by the MHRA as a long-term weight management treatment for adults with obesity or overweight and at least one weight-related comorbidity such as type 2 diabetes, high blood pressure, or high cholesterol. Semaglutide belongs to the glucagon-like peptide-1 (GLP-1) receptor agonist class of medicines, the same drug class as Ozempic, though Wegovy is specifically formulated and dosed for weight management rather than blood sugar control. You may also find our weight loss helpful for targeting related symptoms.

Wegovy vs Ozempic: What Is the Difference?

Both Wegovy and Ozempic contain semaglutide, but they are not interchangeable. Ozempic (semaglutide 0.5mg–1mg) is licensed for type 2 diabetes management, while Wegovy (semaglutide 2.4mg) is licensed specifically for chronic weight management. Wegovy is dosed at a higher maintenance level and is the appropriate choice when a GP or pharmacist is prescribing semaglutide for weight loss rather than glycaemic control. Many customers also benefit from products in our cystitis bladder infection alongside this treatment.

Who Is Wegovy Licensed For in the UK?

In the UK, Wegovy is licensed for adults with a body mass index (BMI) of 30 kg/m² or more, or a BMI of 27 kg/m² or more in the presence of at least one weight-related condition. It is intended to be used alongside a calorie-reduced diet and increased physical activity as part of a comprehensive weight management programme.

What Causes Obesity and Why Can Weight Loss Be Difficult?

Obesity is a complex, chronic condition influenced by a combination of biological, environmental, psychological, and behavioural factors. It is not simply a result of willpower or lifestyle choices alone. Understanding these contributing factors is important when considering a medically supervised weight management approach such as a semaglutide weight loss injection.

  • Hormonal imbalances: Hormones such as leptin and ghrelin regulate hunger and satiety; disruptions can make appetite control significantly harder.
  • Genetics: A family history of obesity can increase an individual's susceptibility to weight gain.
  • Diet and environment: Easy access to high-calorie, ultra-processed foods alongside sedentary lifestyles contributes significantly to excess weight.
  • Mental health: Stress, anxiety, and depression can drive emotional eating behaviours and disrupt sleep, both of which affect weight.
  • Medical conditions: Conditions such as hypothyroidism and polycystic ovary syndrome (PCOS) can make weight loss more difficult.
  • Medications: Certain medicines, including some antidepressants and corticosteroids, are associated with weight gain as a side effect.

How Does Wegovy (Semaglutide) Work?

Wegovy works by mimicking the action of a naturally occurring gut hormone called GLP-1 (glucagon-like peptide-1). This hormone is released after eating and plays a key role in regulating appetite and food intake. By activating GLP-1 receptors in the brain, semaglutide helps to reduce hunger, increase feelings of fullness, and slow gastric emptying, meaning you feel satisfied after smaller portions. This mechanism makes Wegovy a clinically meaningful tool when used as part of a structured weight management plan overseen by a healthcare professional.

Dosing Schedule for Wegovy

Wegovy is initiated at a low dose of 0.25mg once weekly and gradually escalated over approximately 16 to 20 weeks to the maintenance dose of 2.4mg once weekly. This slow titration schedule is designed to help the body adjust to the medicine and to minimise gastrointestinal side effects. The injection is administered subcutaneously (under the skin) into the abdomen, thigh, or upper arm using a pre-filled pen device.

Are There Any Side Effects of Wegovy?

Like all medicines, Wegovy can cause side effects. The most commonly reported side effects are gastrointestinal in nature, including nausea, vomiting, diarrhoea, constipation, and stomach discomfort. These effects are typically mild to moderate and often improve as the body adjusts during the dose escalation phase. More serious but less common side effects include pancreatitis and gallbladder problems. You should always read the patient information leaflet supplied with your medicine and consult your prescribing pharmacist or GP if you experience any concerning symptoms or if side effects persist.

Who Can Use Wegovy Weight Loss Injections?

Wegovy is suitable for adults aged 18 and over who meet the licensed BMI criteria described above and have been assessed as appropriate candidates by a qualified prescriber. It is not suitable for everyone. Wegovy should not be used during pregnancy or breastfeeding, by individuals with a personal or family history of medullary thyroid carcinoma, or by those with multiple endocrine neoplasia syndrome type 2 (MEN2). People with a history of pancreatitis, serious kidney disease, or certain gastrointestinal conditions should discuss their suitability carefully with a GP or pharmacist before starting treatment.

  1. Adults with a BMI of 30 kg/m² or above.
  2. Adults with a BMI of 27 kg/m² or above with a weight-related comorbidity.
  3. Individuals committed to dietary changes and increased physical activity alongside treatment.
  4. Those who have been assessed as suitable by a registered prescriber.

If you are unsure whether Wegovy is right for you, speak to a pharmacist or your GP before purchasing.

How does the semaglutide weight loss injection work?

Semaglutide mimics the GLP-1 hormone, which helps regulate appetite and feelings of fullness. It slows gastric emptying and reduces hunger signals in the brain. When used alongside a reduced-calorie diet and exercise, the Wegovy semaglutide weight loss injection can support significant and sustained weight reduction.

How long does it take for Wegovy to work?

Most people begin to notice appetite reduction within the first few weeks of starting Wegovy. Meaningful weight loss is typically observed after 12 weeks of treatment. The full effect becomes more apparent once the maintenance dose of 2.4mg is reached, usually after around 16 to 20 weeks of gradual dose escalation.

What are the most common side effects of Wegovy?

The most commonly reported side effects include nausea, vomiting, diarrhoea, constipation, and stomach discomfort. These are usually mild and tend to improve as treatment continues. If you experience persistent or severe symptoms, speak to your prescribing pharmacist or GP promptly.

Is Wegovy the same as Ozempic?

Both contain semaglutide but are not the same. Ozempic is licensed for type 2 diabetes management at lower doses, while Wegovy is licensed specifically for chronic weight management at a higher 2.4mg maintenance dose. They should not be used interchangeably without guidance from a qualified prescriber.

How is the Wegovy pen administered?

The Wegovy pen is a pre-filled, single-use injection device used once weekly. It is injected subcutaneously — under the skin — into the abdomen, thigh, or upper arm. Full instructions are included with your medicine, and your pharmacist can provide guidance on correct injection technique if needed.

Is Wegovy available on the NHS?

Wegovy has received NICE approval for use within specialist NHS weight management services in England. However, NHS availability remains limited and is subject to local commissioning decisions. Many patients choose to purchase through a registered private online pharmacy while NHS provision is rolled out more widely.
