Like all medicines, Wegovy (semaglutide) can cause side effects, although not everyone experiences them. These are often more noticeable when starting treatment or increasing the dose.
Common side effects include:
- Nausea, vomiting, diarrhoea and constipation
- Stomach pain, bloating and indigestion
- Headache, dizziness and tiredness
How can I manage side effects?
Eating smaller meals, avoiding rich or fatty foods and staying hydrated may help. If side effects persist or become difficult to manage, speak to your prescriber, as your dose may need reviewing.
When should I seek medical help?
Seek urgent medical assessment for severe, persistent abdominal pain, particularly if it spreads to your back, or sudden loss of vision. Seek emergency help for breathing difficulties or swelling of the face, lips or throat.
Persistent vomiting or diarrhoea can cause dehydration. Contact a healthcare professional promptly if you cannot keep fluids down.
For a complete list of side effects and precautions, read the patient information leaflet supplied with your medication.
