Melatonin capsules are sometimes used as a sleep aid in children, although its safety and effectiveness in this age group have not been fully established. Melatonin is not approved by the Food and Drug Administration (FDA) for use in children, and the American Academy of Pediatrics (AAP) does not currently recommend the use of melatonin for children.
There is some evidence that melatonin may be effective in helping children with certain sleep disorders, such as insomnia and restless leg syndrome. However, more research is needed to determine the long-term effects of melatonin in children, and the appropriate dosage for different age groups.
