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 drug 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.

Dose

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 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.

Alternatives

The best way to lose weight is a healthy diet or meal plan and increased physical exercise. This is the safest and effective method of weight loss. The NHS offers a 12-week weight loss plan here. Further information is available for exercise and diets.

There are a number of reasons why people improving diet and exercise may fail to lose weight. For these people, medicines like Saxenda may prove useful. Another medication used for weight loss is Orlistat.

Orlistat capsules work by preventing around one third of the fat from the food you eat from being digested. By decreasing the amount of fat the body absorbs and improving your diet and exercise routine, it is possible to achieve significant weight loss. Orlistat is a prescription/over the counter medicine.

Another option is weight loss surgery. This is used for people who are very obese. You should discuss this with your GP, who will be best placed to decide if this is a suitable option for you.
