What Mellozzan is and what it is used for

The active substance in Mellozzan, melatonin, belongs to a group of natural hormones produced by the body. The hormone helps to regulate the body’s day and night rhythm.

  • insomnia in children and adolescents 6 – 17 years with ADHD where other sleep support measures are not sufficient.

Melatonin contained in Mellozzan may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.
