tThis product is subject to additional monitoring. ESC = European Society of Cardiology. CCS = Chronic Coronary Syndrome. GLP-1 RA = Glucagon Like Peptide 1 Receptor Agonist. Wegovy®t(semaglutide). Please refer to the full Summary of Product Characteristics (SmPC) before prescribing. Wegovy® 0.25 mg FlexTouch® solution for injection in pre-filled pen. Wegovy® 0.5 mg FlexTouch® solution for injection in pre-filled pen. Wegovy® 1 mg FlexTouch® solution for injection in pre-filled pen. Wegovy® 1.7 mg FlexTouch® solution for injection in pre-filled pen. Wegovy® 2.4 mg FlexTouch® solution for injection in pre-filled pen. Indication(s): Adults: Wegovy® is indicated as an adjunct to a reduced-calorie diet and increased physical activity for weight management, including weight loss and weight maintenance, in adults with an initial Body Mass Index (BMI) of ≥30 kg/m2 (Obesity) or ≥27 kg/m2 to <30 kg/m2 (overweight) in the presence of at least one weight-related comorbidity e.g. dysglycaemia (prediabetes or type 2 diabetes mellitus), hypertension, dyslipidaemia, obstructive sleep apnoea or cardiovascular disease. For trial results with respect to cardiovascular risk reduction, obesity-related heart failure, and populations studied, see section 5.1. of the Wegovy® SmPC. Adolescents: Wegovy® is indicated as an adjunct to a reduced-calorie diet and increased physical activity for weight management in adolescents ages 12 years and above with obesity* and body weight above 60 kg. Treatment with Wegovy® should be discontinued and re-evaluated if adolescent patients have not reduced their BMI by at least 5% after 12 weeks on the 2.4 mg or maximum tolerated dose. *See table 1 in the Wegovy® SmPC for BMI cut-off points for obesity by sex and age. Posology and administration: Administered once weekly at any time of the day, with or without meals. Injected subcutaneously in the abdomen, in the thigh or in the upper arm. The injection site can be changed. It should not be administered intravenously or intramuscularly. For the 7.2 mg dose, inject three doses of 2.4 mg one after each other. The injections can be administered in the same body area but should be at least 5 cm apart. Injection sites should always be rotated to reduce the risk of injection site amyloid deposits. The day of weekly administration can be changed if necessary, as long as the time between doses is at least 3 days (>72 hours). After selecting a new dosing day, once-weekly dosing should be continued. Adults: The maintenance dose of semaglutide 2.4 mg once-weekly is reached by starting with a dose of 0.25 mg. To reduce the likelihood of gastrointestinal symptoms, the dose should be escalated over a 16-week period to the maintenance dose. If needed, the dose can be increased to 7.2 mg once weekly after a minimum of 4 weeks on the 2.4 mg dose in adults with BMI ≥ 30 kg/m2 at treatment initiation. If no additional clinical improvement in body weight is observed with 7.2 mg, lower the dose to 2.4 mg once weekly. In case of significant gastrointestinal symptoms, consider delaying dose escalation or lowering to the previous dose until symptoms have improved. Adolescents: For adolescents ages 12 years and above, the same dose escalation schedule as for adults should be applied. The dose should be increased until 2.4 mg (maintenance dose) or maximum tolerated dose has been reached. Weekly doses higher than 2.4 mg are not recommended in the adolescent population. Patients with type 2 diabetes: When initiating Wegovy®, consider reducing the dose of concomitantly administered insulin or insulin secretagogues (such as sulfonylureas) to reduce the risk of hypoglycaemia. Missed dose: If a dose is missed, it should be administered as soon as possible and within 5 days after the missed dose. If more than 5 days have passed, the missed dose should be skipped, and the next dose should be administered on the regularly scheduled day. If more doses are missed, reducing the starting dose for re-initiation should be considered. Elderly: No dose adjustment is required based on age. Renal impairment: No dose adjustment is required for patients with mild or moderate renal impairment. Experience in patients with severe renal impairment is limited. Semaglutide is not recommended for use in patients with severe renal impairment (eGFR <30 mL/min/1.73m2) including patients with end-stage renal disease. Hepatic impairment: No dose adjustment is required for patients with mild or moderate hepatic impairment. Experience in patients with severe hepatic impairment is limited. Semaglutide is not recommended for use in patients with severe hepatic impairment and should be used cautiously in patients with mild or moderate hepatic impairment. Paediatrics: The safety and efficacy of semaglutide in children below 12 years of age have not been established. Contraindications: Hypersensitivity to the active substance or to any of the excipients. Special warnings and precautions for use: Cases of pulmonary aspiration have been reported in patients receiving GLP-1 receptor agonists undergoing general anaesthesia or deep sedation. Therefore, the increased risk of residual gastric content due to delayed gastric emptying should be considered prior to performing procedures with general anaesthesia or deep sedation. Use of GLP-1 receptor agonists may be associated with gastrointestinal adverse reactions. This should be considered when treating patients with impaired renal function, as nausea, vomiting, and diarrhoea may cause dehydration, which in rare cases can lead to a deterioration of renal function. Patients treated with semaglutide should be advised of the potential risk of dehydration in relation to gastrointestinal side effects and take precautions to avoid fluid depletion. Acute pancreatitis has been observed with the use
of GLP-1 receptor agonists. Patients should be informed of the characteristic symptoms of acute pancreatitis. If pancreatitis is suspected, Wegovy® should be discontinued; if confirmed, Wegovy® should not be restarted. Caution should be exercised in patients with a history of pancreatitis. In the absence of other signs and symptoms of acute pancreatitis, elevations in pancreatic enzymes alone are not predictive of acute pancreatitis. Data from epidemiological studies indicates an increased risk for nonarteritic anterior ischaemic optic neuropathy (NAION) during treatment with semaglutide. There is no identified time interval for when NAION may develop following treatment start. A sudden loss of vision should lead to ophthalmological examination and treatment with semaglutide should be discontinued if NAION is confirmed. Wegovy® should not be used as a substitute for insulin in patients with type 2 diabetes. Wegovy® should not be used in combination with other GLP-1 receptor agonist products. Patients treated with Wegovy® in combination with a sulfonylurea or insulin may have an increased risk of hypoglycaemia. The risk of hypoglycaemia can be lowered by reducing the dose of sulfonylurea or insulin when initiating treatment with a GLP-1 receptor agonist. In patients with diabetic retinopathy treated with semaglutide, an increased risk of developing diabetic retinopathy complications has been observed. Patients with diabetic retinopathy using semaglutide should be monitored closely and treated according to clinical guidelines. There is no experience with Wegovy® in patients with type 2 diabetes with uncontrolled or potentially unstable diabetic retinopathy. In these patients, treatment with Wegovy® is not recommended. Semaglutide treated patients with gastroparesis may experience more serious or severe gastrointestinal adverse events. Semaglutide should be used with caution in these patients, and semaglutide is not recommended if gastroparesis is severe. The safety and efficacy of Wegovy® has not been investigated in patients treated with other products for weight management, with type 1 diabetes, with severe renal or hepatic impairment or with congestive heart failure New York Heart Association (NYHA) class IV. Use in these patients is not recommended. There is limited experience with Wegovy® in patients aged 85 years or more, with mild or moderate hepatic impairment, with inflammatory bowel disease. Use with caution in these patients. If semaglutide is used in combination with a sulfonylurea or insulin, patients should be advised to take precautions to avoid hypoglycaemia while driving and using machines. Fertility, pregnancy and lactation: Women of childbearing potential are recommended to use contraception when treated with semaglutide. There are limited data from the use of semaglutide in pregnant women. Therefore, semaglutide should not be used during pregnancy. If a patient wishes to become pregnant, or pregnancy occurs, semaglutide should be discontinued. Semaglutide should be discontinued at least 2 months before a planned pregnancy due to the long half-life. In lactating rats, semaglutide was excreted in milk. A risk to a breast-fed child cannot be excluded. Semaglutide should not be used during breast-feeding. Effect on fertility unknown.
