What is Saxenda?
Saxenda is an injection used for weight loss. It contains the medicine liraglutide. It can be used alongside diet and exercise to help aid weight loss. Saxenda is a registered trademark of Novo Nordisk.

The weight loss injection can be prescribed for people with a body mass index (BMI) over 30. It can also be used for people with a BMI over 27 who have also been diagnosed with weight-related medical problems. These include:

  • Pre-diabetes and diabetes type 2
  • Hypertension (high blood pressure)
  • High cholesterol
  • Obstructive sleep apnoea

How does Saxenda work?

Saxenda contains the active ingredient liraglutide. Liraglutide is similar to a hormone in the body called glucagon-like peptide-1 (GLP-1). This is an appetite hormone that helps regulate hunger and is released by the intestines after a meal. 

Due to being similar to GLP-1, Saxenda regulates appetite causing you to feel fuller and less hungry. This can lead to eating fewer calories and losing weight.


  • How is Saxenda used?

    Saxenda comes as an injectable pen. The Saxenda pen is injected once daily subcutaneously. The usual injection sites will be the upper arm, upper thigh or abdomen. 

    The starting dose is a daily injection of 0.6mg. This dose is increased at intervals of usually 1 week until a dose of 3.0mg once daily is reached. An example schedule is shown below:

    Week 1 - 0.6mg dose once daily
    Week 2 - 1.2mg dose once daily
    Week 3 - 1.8mg dose once daily
    Week 4 - 2.4mg dose once daily
    Week 5 - 3.0mg dose once daily continuing

    The dose of Saxenda is gradually increased in 1-week intervals to reduce the chances of stomach side effects like nausea, vomiting and diarrhoea.

    If you increase the dose and find the side effects problematic for two weeks or more you should discuss this with your doctor or pharmacist.

  • How does Saxenda work?

    Saxenda contains the ingredient Liraglutide. This works in the same way as a natural substance found in the body called GLP-1, which helps to regulate blood sugar after eating. By mimicking this hormone, Saxenda helps the brain to acknowledge that the body is full after we’ve eaten less food (consuming less calories) than we normally would. Essentially, Saxenda can help you to reduce the number of calories you eat which reduces your body weight as a result.

  • How much weight can you lose on Saxenda?

    Saxenda has been tested for promotion of weight loss and showed that 3,731 participants lost an average of 8% of their body weight over a 56-week trial. The same study also showed that 92% of participants lost weight when Saxenda was used in conjunction with diet and exercise.

  • How long can you stay on Saxenda injections?

    The duration of Saxenda treatment should be regularly reviewed by your doctor. It should be stopped if, after 12 weeks on the 3.0mg daily dose, you have not lost at least 5% of your body weight.

  • How do I use the Saxenda pen?

    Saxenda is injected under the skin (subcutaneous injection). The best places to inject are the front of the waist or the front of the thighs. It is important not to inject Saxenda into a vein or a muscle.
