The number, drawn
Specialists may prescribe melatonin when other sleep methods have not worked
Why it matters
A four-week placebo-controlled trial in children aged 6 to 12 with ADHD and chronic sleep-onset insomnia found melatonin brought sleep onset earlier. Sleep onset moved 26.9 minutes earlier with melatonin and 10.5 minutes later with placebo, while behaviour, cognition and quality of life did not significantly improve. This is short-term sleep evidence, not evidence of an ADHD cure, and longer-term decisions need specialist review.
How to do it
- Bring a description of your child's sleep timing and the approaches already tried.
- Ask the clinician to work out what's behind the trouble getting to sleep.
- If melatonin comes up, ask about the expected benefit, side effects and follow-up.
For children, melatonin is a decision led by a clinician. Discuss side effects, interactions and follow-up. This item gives no dosing or self-treatment advice.
Putting it into practice
In real life
- Ask whether your child's difficulty is delayed sleep timing or another sleep problem.
- Ask what would count as a useful improvement and when it would be reviewed.
Watch out for
- Common mistakeNatural doesn't mean risk-free. Talk melatonin through with the specialist instead of picking a product yourself.
- Common mistakeBetter sleep doesn't guarantee better ADHD symptoms. Agree which sleep outcome you're checking.
