Wegovy Injection UK – Semaglutide Weight Loss Pen

Wegovy is a prescription-only injectable medicine containing semaglutide, approved in the UK for chronic weight management in adults. It is administered once weekly using a pre-filled, disposable injection pen and is intended to be used alongside a reduced-calorie diet and increased physical activity. If you are looking for a clinically recognised option to support long-term weight management, Wegovy injection UK availability through a registered online pharmacy means you can access this treatment following a proper clinical assessment.

Wegovy is manufactured by Novo Nordisk and is licensed by the Medicines and Healthcare products Regulatory Agency (MHRA) for use in the UK. It is not an over-the-counter product and requires a valid prescription issued by a qualified prescriber.

How Semaglutide Works in the Body

Semaglutide belongs to a class of medicines known as GLP-1 receptor agonists. It works by mimicking a naturally occurring hormone called glucagon-like peptide-1, which is released in the gut after eating. By activating GLP-1 receptors in the brain, semaglutide helps to reduce appetite and increase feelings of fullness, which can lead to a reduction in calorie intake over time.

The medicine also slows gastric emptying, meaning food moves more slowly from your stomach into your small intestine. This contributes to a prolonged sense of satiety after meals. Wegovy injection UK is started at a low dose and gradually increased over several months to help your body adjust and to reduce the likelihood of side effects.

Who May Be Suitable for Wegovy Treatment

Wegovy is indicated for adults who meet specific clinical criteria. Your prescriber will assess whether this medicine is appropriate for you based on your individual health profile. You may be considered for Wegovy if you meet one or more of the following:

You have a body mass index (BMI) of 30 kg/m² or above
You have a BMI of 27-30 kg/m² or above alongside at least one weight-related health condition, such as type 2 diabetes, high blood pressure, or dyslipidaemia (high cholesterol)
You have not achieved adequate weight loss through diet and exercise alone
You do not have a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2

Wegovy is not suitable for use during pregnancy or breastfeeding. You can explore our weight loss collection for additional products that may complement a healthy lifestyle programme.

Dosing Schedule and How to Use the Injection Pen

Wegovy is injected subcutaneously — under the skin — once per week, on the same day each week. You can inject it into your abdomen, thigh, or upper arm. The injection site should be rotated each week to avoid skin reactions at the same location. The pre-filled pen is designed for single use and does not require you to draw up or measure a dose manually.

Treatment begins at a starting dose of 0.25 mg once weekly for the first four weeks. The dose is then escalated gradually over approximately 16 weeks until you reach the maintenance dose of 7.2 mg once weekly. This step-up approach is intended to minimise gastrointestinal side effects such as nausea, vomiting, and diarrhoea, which are among the most commonly reported effects during the early stages of treatment.

Storage, Clinical Monitoring, and Important Safety Information

Wegovy pens should be stored in a refrigerator between 2°C and 8°C before first use. Once in use, the pen can be kept at room temperature (below 30°C) or in the refrigerator for up to 6 weeks. The pen must not be frozen, and you should keep it away from direct heat and sunlight. Always check the expiry date before use and dispose of used pens safely in an approved sharps container.

You should attend regular follow-up appointments with your prescriber to monitor your progress, weight, and any side effects. If you have a history of pancreatitis, gallbladder disease, diabetic retinopathy, or kidney problems, you must inform your prescriber before starting treatment. Wegovy may interact with other medicines, particularly those used to manage blood glucose levels. You can also browse our diabetes monitoring collection if you are managing blood sugar alongside your weight loss treatment.
