If your child keeps struggling to fall asleep, ask a clinician whether melatonin is right for them.

**The number:** Specialists may prescribe melatonin when other sleep methods have not worked ([NHS, 2025](https://www.nhs.uk/conditions/adhd-children-teenagers/))

## The evidence

- How sure: Certainty of evidence: Not rated. Measured in people with ADHD.
- Evidence grade: B. Grade B: trials in ADHD with low certainty, or strong general health evidence with a sourced reason it matters more with ADHD.
- Basis: Small short-term placebo-controlled ADHD insomnia trial plus NHS guidance; no formal certainty rating.
- Benefit: 45/100. The benefit score is an editorial prioritization for the general list, weighted by certainty. It is not a prediction of what will happen for you.

## 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

1. Bring a description of your child's sleep timing and the approaches already tried.
2. Ask the clinician to work out what's behind the trouble getting to sleep.
3. If melatonin comes up, ask about the expected benefit, side effects and follow-up.

## Talk to a clinician first

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

### Start now

- 1 minute: Write down one sleep question you want answered before melatonin comes up.
- 5 minutes: List the sleep approaches already tried and whether they helped.
- 15 minutes: Prepare your sleep history, medicine list and questions for the specialist appointment.

### What it looks like

- 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.

### Common mistakes

- Natural doesn't mean risk-free. Talk melatonin through with the specialist instead of picking a product yourself.
- Better sleep doesn't guarantee better ADHD symptoms. Agree which sleep outcome you're checking.
