Loss of fluid and dehydration
When starting treatment with Saxenda®, you may lose body fluid or become dehydrated. This may be due to feeling sick (nausea), being sick (vomiting) and diarrhoea. It is important to avoid dehydration by drinking plenty of fluids. Talk to your doctor, pharmacist or nurse if you have any questions or concerns.

Children and adolescents
Saxenda® should not be used in children and adolescents under 18 years of age. This is because the effects and safety of this medicine have not been studied in this age group.

If you adjust your insulin dose your doctor may recommend you to monitor your blood sugar more frequently.
