Saxenda | Weight Loss Injection

What are Saxenda Pens?

Saxenda is a daily injectable medicine designed for weight loss in people who are overweight or obese (with a BMI that is over 30). They are also known as weight loss pens, weight loss injections, and the skinny jab. You can check your BMI here:

Visit the BMI calculator tab to work out your BMI

If your BMI is above 27, but less than 30, then you can use these injections if you have the following weight-related medical conditions:

  • Type 2 diabetes (including pre-diabetes)
  • High blood pressure (hypertension)
  • High cholesterol
  • Obstructive sleep apnoea

Who can use the “skinny jab”?

This medicine is licensed for people aged 18 years and above.

DO NOT use if you are allergic to liraglutide or any of the other ingredients of this medicine.

It is NOT recommended for people:

  • Aged over 75 years
  • With heart failure
  • With severe stomach or gut problems (e.g. gastroparesis or inflammatory bowel disease)
  • Who are pregnant or breastfeeding

How do weight loss injections work?

Saxenda is designed to suppress your appetite. It contains the active ingredient liraglutide, which mimics the hormone glucagon-like peptide-1 (GLP-1). Liraglutide helps regulate blood sugar by decreasing the production of insulin-opposing glucagon. This slows down the emptying of the stomach, meaning you feel fuller for longer.

Is Saxenda Effective?

The weight loss injections are shown to be very effective alongside a calorie-controlled diet.

Trials carried out by the manufacturer showed that 6 in 10 people lost 5% or more of their body weight, and 1 in 3 people lost more than 10% of their body weight.

How to use these Injections

Saxenda is injected daily into the upper arm, abdomen, or upper thigh. You can use it at any time of the day, and with or without food.  The starting dose is 0.6mg, which is gradually increased at 1 week intervals until you reach 3.0mg, usually around week 5.  Once you reach this dose, you can carry on using Saxenda until your treatment period ends.

Treatment should be discontinued after 12 weeks if you have not lost at least 5% of your body weight on the highest dose of 3.0mg.
