The active ingredient, semaglutide, mimics a natural hormone called GLP-1, which is involved in appetite and calorie intake.Who can take Wegovy?A healthcare professional will assess whether Wegovy is appropriate for you based on factors such as your body mass index (BMI), medical history and overall health.In the UK, this assessment typically includes whether your BMI meets the criteria for treatment. This is usually:You have a BMI of 30 or aboveYou have a BMI of 27 or above and have at least one weight-related complication, such as sleep apnoea or hypertensionThis will be considered alongside your overall health and individual circumstances.Wegovy is not suitable for anyone who is allergic to its ingredients, has severe digestive problems, is pregnant, trying to become pregnant or breastfeeding.Before starting treatment, please let your healthcare provider know if:You have ever had pancreatitisYou are taking diabetes medication such as insulin or a sulfonylureaYou have diabetic eye diseaseYou are taking warfarin or other medicines to reduce blood clottingHow do you use Wegovy?Wegovy should be stored in the fridge and injected once weekly into an area such as your abdomen or upper arm. This should be done on the same day each week.New patients usually start on the lowest dose, 0.25mg, then increase the dose every four weeks to 0.5mg, 1mg and 1.7mg, until they reach 2.4mg in month 5. This may be adjusted based on tolerability. This gradual increase helps the body get used to semaglutide while reducing the likelihood of potential side effects.After at least 4 weeks on 2.4mg, some adult patients with obesity, defined as a BMI of 30 or above, may be considered for a higher weekly dose of 7.2mg if clinically appropriate and well tolerated. This decision is made by the prescriber.Wegovy side effectsSide effects from Wegovy are most common when starting treatment or increasing your dose.
