Wegovy (Semaglutide) UK

Wegovy (semaglutide) is a prescription medicine used alongside a reduced-calorie diet and increased physical activity to support weight loss and long-term weight management. It belongs to a group of medicines called Wegovy (Semaglutide) UK | Weight Management Treatmentagonists and works by helping reduce appetite and increasing feelings of fullness.

What Is Wegovy (Semaglutide)?

Wegovy contains the active ingredient semaglutide, which is designed to act in a similar way to the naturally occurring hormone GLP-1.

GLP-1 plays an important role in appetite and food intake. Semaglutide acts on GLP-1 receptors involved in appetite regulation, helping people feel fuller and less hungry. This can support reduced food intake when combined with healthy lifestyle changes.

Who May Be Prescribed Wegovy?

Wegovy may be prescribed for adults with:

• A BMI of 30 kg/m² or above, which is within the obesity range; or
• A BMI of at least 27 kg/m² but below 30 kg/m² together with a weight-related health condition.

A healthcare professional should assess your medical history, current medicines, BMI and individual circumstances before prescribing Wegovy.

How Does Wegovy Work?

Semaglutide works by activating GLP-1 receptors involved in appetite control. It can help you feel fuller for longer, reduce hunger and reduce cravings for food.

Wegovy is intended to be used as part of a wider weight-management programme that includes appropriate nutrition and physical activity. It is not intended to replace a balanced diet or regular exercise.

How Is Wegovy Taken?

Wegovy is administered as a once-weekly injection under the skin. The injection may be given in areas such as the abdomen, thigh or upper arm.

Treatment is normally introduced at a lower dose and increased gradually according to the prescribing instructions. This gradual approach can help reduce gastrointestinal side effects. Always follow the dose and instructions provided by your prescriber or the medicine’s patient information leaflet.

Possible Side Effects

Like all medicines, Wegovy can cause side effects. Common effects can include digestive symptoms such as:

• Nausea
• Vomiting
• Diarrhoea
• Constipation
• Stomach or abdominal discomfort

More serious side effects can occur. UK safety guidance highlights a potential risk of acute pancreatitis with GLP-1 medicines, including semaglutide. Seek urgent medical attention if you develop severe or persistent abdominal pain, particularly if it spreads to your back or occurs with nausea or vomiting.

Always read the official patient information leaflet and speak with your prescriber or pharmacist if you are concerned about side effects.

Wegovy, Pregnancy and Breastfeeding

Wegovy should not be used during pregnancy. If you are planning a pregnancy, speak with your healthcare professional before using semaglutide. NHS guidance states that semaglutide should be stopped at least 2 months before trying to become pregnant. Semaglutide is also not used while breastfeeding.

Is Wegovy Prescription Only in the UK?

If obtaining Wegovy privately, use a legitimate, registered pharmacy and make sure an appropriate clinical consultation takes place.
