Saxenda® (liraglutide injection 3mg) Patient Information Leaflet

What is a Patient Information Leaflet?

The Patient Information Leaflet (PIL) is the leaflet included in the pack with a medicine. It is written for patients and gives information about taking or using a medicine. It is possible that the leaflet in your medicine pack may differ from this version because it may have been updated since your medicine was packaged.

1. What Saxenda® is and what it is used for

What Saxenda® is
Saxenda® is a weight loss medicine that contains the active substance liraglutide. It is similar to a natural occurring hormone called glucagon-like peptide-1 (GLP-1) that is released from the intestine after a meal. Saxenda® works by acting on receptors in the brain that control your appetite, causing you to feel fuller and less hungry. This may help you eat less food and reduce your body weight.

What Saxenda® is used for
Saxenda® is used for weight loss in addition to diet and exercise in adults aged 18 and above who have:

  • a BMI of 30 kg/m² or greater (obese) or
  • a BMI of 27 kg/m² and less than 30 kg/m² (overweight) and weight-related health problems (such as diabetes, high blood pressure, abnormal levels of fats in the blood or breathing problems during sleep called ‘obstructive sleep apnoea’). BMI (Body Mass Index) is a measure of your weight in relation to your height.

You should only continue using Saxenda® if you have lost at least 5% of your initial body weight after 12 weeks on the 3 mg/day dose (see section 3). Consult your doctor before you continue.

Diet and exercise
Your doctor will start you on a diet and exercise programme. Stay on this programme while you are using Saxenda®.

Loss of fluid and dehydration

It is important to avoid dehydration by drinking plenty of fluids. Talk to your doctor, pharmacist or nurse if you have any questions or concerns. See section 4.

Children and adolescents
Saxenda® should not be used in children and adolescents under 18 years of age. This is because the effects and safety of this medicine have not been studied in this age group.

Other medicines and Saxenda®

  • you are taking medicines for diabetes called ‘sulfonylurea’ (such as glimepiride or glibenclamide) or if you are taking insulin – you may get low blood sugar (hypoglycaemia) when you use these medicines with Saxenda®.

If you adjust your insulin dose your doctor may recommend you to monitor your blood sugar more frequently.
