1. What Wegovy is and what it is used for
What Wegovy is
Wegovy is a medicine for weight loss and maintenance that contains the active substance semaglutide. It is similar to a natural hormone called glucagon-like peptide-1 (GLP-1), which is released from the gut after meals. It works by affecting targets (receptors) in the brain that control your appetite, making you feel fuller and less hungry and having fewer food cravings. This will help you eat less food and reduce your weight. Wegovy may also help prevent heart disease.
What Wegovy is used for
Wegovy is used together with diet and exercise to reduce weight and to help keep your weight under control. It is used in adults who have a BMI of 30 kg/m2 or more (obese) or a BMI of at least 27 kg/m2 but less than 30 kg/m2 (overweight) who have health problems related to their weight (such as diabetes, high blood pressure, abnormal levels of fat in the blood, a problem with breathing during sleep called ‘obstructive sleep apnoea’, or have ever had a heart attack, stroke or problems with blood vessels). BMI (body mass index) is a measure of your weight in relation to your height. Wegovy is used together with diet and exercise to control weight in adolescents aged 12 years and over who are obese and weigh >60 kg. As an adolescent, you should only continue using Wegovy if you have reduced your BMI by at least 5% after 12 weeks on 2.4 mg or the maximum tolerated dose (see section 3). Talk to your doctor before continuing.
2. What you need to know before you use Wegovy
Do not use Wegovy
if you are allergic to semaglutide or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor, pharmacist or nurse before using Wegovy.
The use of Wegovy is not recommended if:
you are using other weight loss products,
you have type 1 diabetes,
you have severely reduced kidney function,
you have severely reduced liver function,
you have severe heart failure,
you have an eye disease related to diabetes (retinopathy).
There is limited experience with Wegovy in patients:
85 years of age and older,
with liver problems,
with a serious stomach or intestinal problem that causes delayed emptying of the stomach (called gastroparesis), or if you have inflammatory bowel disease.
Please consult your doctor if any of the above apply to you.
If you know that you are going to have an operation where you will be under anesthesia (sleeping), you should tell your doctor that you are being treated with Wegovy.
Dehydration
You may experience nausea, vomiting or diarrhea during treatment with Wegovy. These side effects can lead to dehydration (loss of fluids). It is important to drink enough fluids to prevent dehydration. This is especially important if you have kidney problems. Talk to your doctor if you have any questions or concerns.
Inflammation of the pancreas
If you have severe and persistent pain in your stomach area (see section 4), see a doctor immediately, as this may be a sign of inflammation of the pancreas (acute pancreatitis).
People with type 2 diabetes
Wegovy cannot be used as a substitute for insulin. Do not use Wegovy in combination with other medicines that contain GLP-1 receptor agonists (such as liraglutide, dulaglutide, exenatide or lixisenatide).
Low blood sugar (hypoglycaemia)
Combining sulphonylureas or insulin with this medicine may increase the risk of low blood sugar (hypoglycaemia). Please see section 4 for warning signs of low blood sugar. Your doctor may want you to test your blood sugar levels. This will help your doctor
determine whether the dose of your sulphonylurea or insulin needs to be changed to reduce the risk of low blood sugar.
Diabetic eye disease (retinopathy)
If you have diabetic eye disease and are using insulin, this medicine may cause your vision to get worse and may require treatment. Rapid improvement in blood sugar control may cause temporary worsening of your eye disease. If you have diabetic eye disease and experience eye problems while taking this medicine, talk to your doctor.
Children and adolescents
The safety and efficacy of Wegovy in children under 12 years of age have not been studied and its use in this population is not recommended.
Other medicines and Wegovy
You should tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicines.
In particular, you should tell your doctor if you
Tell your pharmacist or nurse if you are using medicines containing the following:
Warfarin or other similar medicines taken by mouth to reduce blood clotting (oral anticoagulants). When you start treatment with e.g. warfarin or similar medicines, you may need frequent blood tests to determine your blood's ability to clot.
Pregnancy and breast-feeding
This medicine should not be used during pregnancy, as it is not known whether it may affect the unborn baby. It is therefore advisable to use contraception while using this medicine. If you want to become pregnant, you should stop using this medicine at least two months in advance. If you become pregnant, are pregnant, think you may be pregnant, or are planning to become pregnant while using this medicine, talk to your doctor immediately, as your treatment will need to be stopped.
Do not use this medicine if you are breast-feeding, as it is not known whether it passes into breast milk.
Driving and using machines
Wegovy is unlikely to affect your ability to drive or use machines. Some patients may feel dizzy when taking Wegovy, mainly during the first 4 months of treatment (see section 4). If you feel dizzy, be very careful when driving or using machines. If you need more information, talk to your doctor, pharmacist or nurse.
People with type 2 diabetes
If you use this medicine in combination with sulphonylureas or insulin, your blood sugar may become very low (hypoglycaemia), which may impair your ability to concentrate. Avoid driving or using machines if you get any signs of low blood sugar. See section 2, “Warnings and precautions” for information on the increased risk of low blood sugar, and section 4 for the warning signs of low blood sugar. Talk to your doctor for more information.
