EN TERMES SIMPLES
Le liraglutide est un médicament injecté sous la peau une fois par jour. Comme le sémaglutide, il imite l’hormone intestinale naturelle GLP-1, qui indique au cerveau que vous avez assez mangé. La faim et les envies de nourriture diminuent ainsi. Dans l’UE, il est vendu sous le nom Saxenda pour la gestion du poids et s’utilise avec une alimentation moins calorique et davantage d’activité physique. Il est autorisé dans l’UE pour la gestion du poids depuis mars 2015.
Victoza est autorisé dans l’UE depuis le 23 mars 2015. Un médecin habilité peut donc vous le prescrire si ce traitement est adapté à votre situation médicale.

DE QUOI S’AGIT-IL
It copies the gut hormone GLP-1, which increases the feeling of fullness and reduces hunger and food cravings.

INFOS SUR LA MARQUE
À propos du traitement
Victoza contient la substance active liraglutide.
Principe actif: Liraglutide · Dosages: 0.6 – 3 mg / day
Liraglutide is a GLP-1 receptor agonist given as a daily subcutaneous injection. It was one of the first in its class approved in Europe for weight management in adults with obesity, or overweight with comorbidities.
Compared with weekly GLP-1s, its daily dosing can be useful when flexibility of adjustment matters or when a semaglutide hasn't been tolerated. The doctor weighs this up in your consultation — two GLP-1 agonists are never combined.
MODE D'ACTION
Like other GLP-1 analogues, liraglutide mimics a natural gut hormone: it eases hunger signals and produces earlier fullness, so you tend to eat less. Being shorter-acting, its dose is adjusted day by day.
Liraglutide is a copy of a natural gut hormone called GLP-1, which the body releases after eating. The EU product information describes it as an acylated human GLP-1 analogue with 97% amino acid sequence homology to the human hormone, and it binds to and activates the GLP-1 receptor.
GLP-1 receptors also sit in brain regions that regulate appetite. The product information reports that liraglutide increases feelings of fullness and satiety while lowering hunger and prospective food consumption, so people eat less. It does not increase energy expenditure compared with placebo.
Liraglutide has an elimination half-life of roughly 13 hours, which is why it is injected once every day rather than once a week like semaglutide or tirzepatide. It also raises insulin and lowers glucagon in a glucose-dependent way, and weight is lost mainly as fat mass.
Comment il aide
Earlier fullness and calmer hunger signals through the day.
Daily titration lets the doctor fine-tune the dose to your tolerance.
Among the first weight-management GLP-1s approved in Europe.
À quoi s'attendre
Treatment starts at a low daily dose and steps up through the intermediate doses as tolerated. Your doctor sets the pace and adjusts if side effects appear.
Typical escalation
AU QUOTIDIEN
Liraglutide is injected once daily, at any time of day, with or without food. Unlike weekly injections it needs a dose every 24 hours, so it is easiest to pick a convenient time and keep to it.
Treatment starts at 0.6 mg once daily and rises by 0.6 mg at intervals of at least a week, reaching the 3.0 mg maintenance dose in week 5. The slow climb is there to improve stomach and bowel tolerance.
The injection goes under the skin of the abdomen, the thigh or the upper arm. It must never be given into a vein or a muscle. Rotate the site each day to reduce the risk of amyloid deposits building up under the skin.
Look at the liquid before you inject. It should be clear and colourless, or almost colourless. With a new pen, do the flow check described in the instructions so you can see a drop appear at the needle tip before setting your dose.
If you remember within 12 hours of your usual time, take the dose as soon as you can. If there is less than 12 hours until the next one, skip it and carry on as normal. Never take an extra dose.
Unused pens are kept in a refrigerator between 2 and 8 degrees Celsius, away from the freezer compartment, and must not be frozen. A pen in use can be stored below 30 degrees Celsius or refrigerated, and is discarded one month after first use.
Nausea, vomiting and diarrhoea are common at the start and can leave you short of fluid. Dehydration has been linked to kidney impairment and acute kidney failure on GLP-1 medicines, so drink plenty and tell your doctor if you cannot keep fluids down.
Liraglutide is licensed as an addition to a reduced-calorie diet and increased physical activity, not as a replacement for them. Every trial result quoted on this page comes from people doing both alongside the daily injection.

QUI NE DOIT PAS LE PRENDRE ET QUI DOIT REDOUBLER DE PRUDENCE
| MÉDICAMENT OU SUBSTANCE | CE QUI PEUT ARRIVER | CE QUE FAIT LE MÉDECIN |
|---|---|---|
| Insulin and sulfonylureas (for example gliclazide) | Combined use in type 2 diabetes raises the risk of low blood sugar, sometimes severe. | The prescriber may lower the insulin or sulfonylurea dose and asks for blood glucose self-monitoring. |
| Other GLP-1 receptor agonists | Two medicines acting on the same receptor add side effects without an established extra benefit. | Liraglutide for weight management must not be combined with another GLP-1 receptor agonist. |
| Warfarin and other coumarin blood thinners | No interaction study was done, and a clinically relevant effect on warfarin cannot be excluded. | The prescriber arranges more frequent INR checks when liraglutide is started. |
| Oral medicines in general | Liraglutide slightly delays stomach emptying, which can slow how fast a tablet is absorbed. | Interaction studies showed no clinically relevant delay, so no dose change is required. |
| Paracetamol | Peak paracetamol level fell by 31% and was reached up to 15 minutes later; total exposure was unchanged. | No dose adjustment is needed for paracetamol taken alongside liraglutide. |
| Combined oral contraceptives | Peak ethinylestradiol and levonorgestrel levels fell by 12% and 13%, with no relevant change in total exposure. | The contraceptive effect is expected to be unaffected, so no change is required. |
| Atorvastatin, digoxin and lisinopril | Peak levels fell by 38%, 31% and 27% respectively, with only small changes in total exposure. | No dose adjustment of any of these three is required based on those results. |
| General anaesthesia or deep sedation | Delayed stomach emptying can leave food in the stomach, and pulmonary aspiration has been reported. | Tell the anaesthetic team you take liraglutide before any procedure needing anaesthesia or sedation. |
DONNÉES CLINIQUES
The SCALE phase 3 programme tested liraglutide 3.0 mg once daily against placebo in 5,358 adults, and reported a mean body-weight change of -8.0% at 56 weeks compared with -2.6% on placebo.
3,731 adults with BMI >= 30, or >= 27 with dyslipidaemia or hypertension · 56 weeks
SCALE Obesity and Prediabetes. Placebo changed -2.6%. In kilograms the change was -8.4 kg versus -2.8 kg from a mean baseline of 106.3 kg.

SCALE Maintenance. Placebo changed -0.2%. 81.4% on liraglutide kept at least 5% of the run-in loss, versus 48.9% on placebo.
Source: SCALE Maintenance: weight maintenance and additional weight loss with liraglutide after low-calorie-diet-induced weight lossThese figures are group averages from randomised trials, not a prediction for any one person. Some participants lost far more than the average and some lost very little, and everyone in these trials was also following an energy-restricted diet with exercise counselling alongside the daily injection. The product information also notes that of the people who had lost less than 5% after 12 weeks on the full dose, 93.4% did not go on to reach a 10% loss at one year, which is why the prescriber reviews progress at that point.
