Saxenda is a drug injected every day to help aid weight loss. It contains the active ingredient liraglutide. Saxenda is prescribed to those with a high BMI, and is administered as a daily injection from Saxenda injection pens.

It was first approved in the UK in 2017; initially only available via private prescription. Since then, Saxenda has been made available on the NHS under certain strict criteria. In this post, we explain who can be offered Saxenda by the NHS.


How Does Saxenda Work?

Saxenda contains the active ingredient liraglutide. Liraglutide mimics a hormone called GLP-1, which is released by the body after eating. Liraglutide works by acting on receptors in the brain that control appetite. This helps to make you feel fuller and less hungry, which, in turn, can lead to eating less during meals and in turn lead to weight loss.

Saxenda is available from private weight-loss clinics for people above the age of 18 who have a:

    • body mass index (BMI) of 30 or higher

    • BMI of 27 or higher and weight-related conditions such as high blood pressure or type 2 diabetes


It should be used alongside a reduced calorie diet and exercise to maximise Saxenda’s effects and help you lose body weight.

Saxenda is delivered by an injection in the upper arm, torso or thigh.


Is Saxenda Free on the NHS?

When Saxenda’s UK launch was first authorised, it was not available via the NHS. However, in December 2020 this was updated to allow Saxenda on the NHS in certain circumstances. This made it the first weight-loss medicine approved by the NHS in 10 years. Another weight-loss treatment, Orlistat, was first approved by the NHS in 2010.

It can only be offered to patients through NHS weight management services in specialist centres, called tier 3 weight management services. Only patients who meet certain criteria can be prescribed Saxenda on the NHS.

What are the Criteria to Get Saxenda on the NHS?

Guidelines recommend that liraglutide (Saxenda) can be prescribed alongside a reduced-calorie diet and increased physical activity. It can only be prescribed in patients with all of the following:

  • A BMI of at least 35, or 32.5 for some minority ethnic groups*
  • Non-diabetic high blood sugar (sometimes known as pre-diabetes)
  • A high risk of developing heart problems like strokes or heart attacks, for example, because they have high cholesterol or high blood pressure

*The BMI threshold is 32.5 for people of black African, African-Caribbean, Chinese or South Asian origin. This is because people from these ethnic groups are thought to be at an increased risk of obesity-related illnesses at a lower BMI than the white population.

Your doctor may recommend Saxenda if:

  • Weight loss cannot be achieved by diet and exercise on its own
  • Other weight loss treatments have not worked or if you cannot take them

The reason for the Saxenda NHS criteria is that people who meet the above factors are at a high risk of experiencing the negative consequences of obesity. This means they are likely to gain the most benefit from using Saxenda. The NHS guidelines stated it can be prescribed for up to two years; however, Saxenda can only be continued after 12 weeks if weight loss is adequate. You should lose at least 5% of your beginning body weight. Discuss your Saxenda progress with your doctor before you continue.

You should speak to your GP for further advice if you fit the criteria and want to learn more about Saxenda on the NHS.


Where Can I Buy Saxenda Privately?

The NHS looks at the cost-effectiveness of medicines when deciding whether they should be available on the NHS. The criteria for prescribing Saxenda to patients privately is different. Patients in the following categories can be prescribed Saxenda privately:

  • A BMI of 30 or higher
  • A BMI of 27 or higher and weight-related conditions such as Type 2 diabetes, high blood pressure, high cholesterol, and sleep apnea.

Another weight loss injection called Wegovy has been recently approved in the UK. This has been created by Novo Nordisk, the same company behind Saxenda. It works in a similar way, but most patients will find it easier to use because it’s only injected once a week, rather than daily.
