About this treatment
Active ingredient: Semaglutide.
The active ingredient in Wegovy is semaglutide. It helps regulate your appetite, which can mean you eat less.
It is used alongside a reduced-calorie diet and more physical activity.
How it's taken
Wegovy is injected once a week with a pen, into your stomach, upper arm or thigh.
Strengths: 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, 2.4 mg, 7.2 mg.
If you are new to Wegovy, you usually start on 0.25 mg once a week, and the dose is increased gradually. The clinician decides your dose.
If you are already taking it and want a higher or lower dose, you will need to provide evidence of your prescription.
