About Saxenda

Saxenda is manufactured by Novo Nordisk. It contains liraglutide as the active ingredient, a glucagon-like peptide-1 receptor agonist (GLP-1 receptor agonist). It is used for weight loss and to keep the weight off.

It is used for adults with obesity (BMI (body mass index) 30 kg/m2 or greater), or adults that are overweight (BMI 27 kg/m2 or greater) who also have weight-related medical problems such as hypertension (high blood pressure), type 2 diabetes mellitus, or dyslipidemia.

Saxenda may also be used in obese children aged 12 to 17 years of age, who have a bodyweight above 60 kg for weight management. Saxenda is used with a healthy diet and increased physical activity.

NowPatient offers Saxenda as a treatment for weight loss only, following an online consultation with a prescribing clinician.

At the end of the consultation, the clinician will decide if a treatment plan is suitable for you. If it is, the clinician will issue you with a prescription which can then be ordered, paid for and delivered directly to your chosen address by NowPatient.
