Can liraglutide be used for weight loss?

Official answer


Yes, the Saxenda brand of liraglutide is approved to be used for weight loss. The Victoza brand of liraglutide is only approved to treat type 2 diabetes, but may also help you lose some weight and protect your heart. Both Saxenda and Victoza are used in addition to diet and exercise. Do not use Saxenda and Victoza at the same time.

Liraglutide is similar to a hormone that occurs naturally in the body and helps to control blood sugar, insulin levels, and digestion. Liraglutide is commonly associated with digestive tract side effects like nausea, vomiting and diarrhea. In general, these side effects decrease over time for most people as their body gets used to the medicine.


Saxenda injection is approved to be used with diet and exercise for weight loss in adults who are obese or overweight with certain health conditions such as high blood pressure, type 2 diabetes mellitus, or high cholesterol (lipid) levels.

Saxenda can also be used in children 12 to 17 years of age with a body weight above 60 kg (132 lb) and obesity (a body mass of 30 kg/m2 or greater), in addition to diet and exercise.

The Saxenda brand of liraglutide is not used for treating type 1 or type 2 diabetes.

In 56-week long clinical studies of Saxenda in over 3,700 adults, 85% of patients lost some weight.

  • 3 of out 5 people lost an average of 12 lb (5.5 kg), a 5% or more weight loss
  • 1 of 3 people lost an average of 23 lb. (10.5 kg), a 10% or more weight loss
  • 6% of patients lost an average of 47 lb. (21 kg), a 20% or more weight loss

Victoza is not specifically approved by the FDA to be used for weight loss, like Saxenda, but can help with weight loss when used to treat patients with type 2 diabetes.
