1. What Byesilor is and what it is used for
What Byesilor is
Byesilor is a weight-loss medicine containing the active substance liraglutide. This substance mimics a naturally occurring hormone, glucagon-like peptide-1 (GLP-1), which is released from the intestines after a meal. Byesilor works by acting on receptors in the brain that regulate appetite, causing a feeling of fullness and reducing hunger. This may help reduce the amount of food consumed and lead to weight loss.
What Byesilor is used for
Byesilor is a medicine used to support weight loss, in combination with diet and exercise, in adults aged 18 years and older who have:
- a body mass index (BMI) of 30 kg/m² or higher (obesity), or
- a BMI of 27 kg/m² to less than 30 kg/m² (overweight) and have weight-related medical conditions (such as diabetes, high blood pressure, abnormal blood lipid levels, or sleep apnoea). Body Mass Index (BMI) is a measure of body weight relative to height.
Treatment with Byesilor should only be continued if body weight has decreased by at least 5% after 12 weeks of treatment at a dose of 3.0 mg/day (see section 3). To continue treatment, consult your doctor.
Byesilor may also be used as an adjunct to a healthy diet and increased physical activity for weight management in adolescents aged 12 years and older who have:
- obesity (diagnosed by a doctor)
- body weight above 60 kg
Treatment with Byesilor should only be continued if body mass index has decreased by at least 4% after 12 weeks of treatment at a dose of 3.0 mg/day or at the maximum tolerated dose (see section 3). To continue treatment, consult your doctor.
Diet and exercise
Your doctor will start you on a diet and exercise programme. You must follow these recommendations throughout your treatment with Byesilor.
2. Important information before using Byesilor

Diabetes patients
Patients with diabetes should not use Byesilor as a substitute for insulin.
Pancreatitis
If the patient has or has had a disease of the pancreas, they should consult their doctor.
Gallbladder inflammation and gallstones
During significant weight loss, patients are at risk of developing gallstones and, consequently, gallbladder inflammation. Treatment with Byesilor should be discontinued and medical advice sought immediately if sudden pain occurs in the upper part of the abdomen, usually stronger on the right side under the ribs. The pain may radiate to the back or right shoulder. See section 4.
Thyroid disease
In case of thyroid disease, including nodules and goitre, consult your doctor.
Heart rate
If palpitations (awareness of heartbeat) or a sensation of increased heart rate at rest occur during treatment with Byesilor, consult your doctor.
Fluid loss and dehydration
After starting treatment with Byesilor, loss of body fluids or dehydration may occur. This may be caused by nausea, vomiting, and diarrhoea. Patients should drink plenty of fluids to avoid dehydration. If in doubt or if you have any questions, consult your doctor, pharmacist, or nurse. See section 4.
Children and adolescents
The safety and efficacy of liraglutide in children under 12 years of age have not been studied.
Byesilor and other medicines
Tell your doctor, pharmacist, or nurse about all medicines the patient is currently taking, has recently taken, or plans to take.
In particular, inform your doctor, pharmacist, or nurse if:
- the patient is taking antidiabetic medicines of the sulfonylurea class (such as glimepiride or glibenclamide) or insulin – low blood sugar (hypoglycaemia) may occur when Byesilor is used together with these antidiabetic medicines. To prevent low blood sugar, the doctor may adjust the dose of the antidiabetic medicine. See section 4 – warning symptoms of low blood sugar. If insulin dose adjustment is needed, the doctor may recommend more frequent blood sugar monitoring.
- the patient is taking warfarin or other oral medicines that reduce blood clotting (anticoagulants). More frequent blood clotting tests may be necessary.
Pregnancy and breastfeeding
If the patient is pregnant, suspects she may be pregnant, or is planning a pregnancy, she should not use Byesilor. There are no data on the effects of liraglutide on the health of the unborn child.
Breastfeeding should not be undertaken during treatment with Byesilor. There is no information on whether liraglutide passes into human milk.
Driving and using machines
Liraglutide probably has no influence on the ability to drive and use machines.
However, dizziness may occur in some patients treated with liraglutide, mainly during the first 3 months of treatment (see section "Possible side effects"). If dizziness occurs, particular caution should be exercised when driving or operating machinery. For further information, consult your doctor.

Before first use of a new injector, always ensure a drop of solution appears at the needle tip. This confirms that the solution flow is not blocked. If no drop appears, the medicine will not be delivered, even though the dose counter may move. This may indicate that the needle is blocked or damaged. Using a new injector without performing the flow check before first injection may result in not receiving the prescribed dose and lack of intended effect of Byesilor. | |
3 Setting the dose
| Warning: Turning the dose selector knob forward causes it to extend automatically, as shown in the illustration, which is a normal phenomenon.![]() |
How much solution remains?
| ![]() |
| If 3.0 is visible, at least 3.0 mg of medicine remains in the injector. If the dose counter stops before 3.0 mg, this means the injector does not contain enough solution to deliver a full 3.0 mg dose. If more medicine is needed than remains in the current injector The dose may be divided between the current and a new injector only if trained by a doctor or nurse. Use a calculator to determine doses according to instructions provided by the doctor or nurse. Calculations must be performed very carefully. If in doubt about how to divide the dose between two injectors, select and inject the required dose using a new injector. | ![]() |
