What is Wegovy?
Wegovy contains semaglutide, a GLP-1 receptor agonist that helps regulate appetite and food intake. It is prescribed alongside a reduced-calorie diet and increased physical activity for eligible adults in the UK.
Wegovy doses and timeline
Treatment normally starts at 0.25mg once a week and increases gradually over several months. Starting low gives your body time to adjust and can make nausea and other gastrointestinal side effects easier to manage. Your prescriber decides whether and when to increase the dose.
Wegovy in the UK
Wegovy may be available through NHS specialist weight-management services for people who meet local eligibility criteria. Private prescriptions are also available through regulated UK clinics, where the total cost depends on dose, consultation fees, delivery and ongoing support.
