Insights
Melatonin effectively treats sleep disturbances in children with neurodevelopmental disorders. Lower doses (2.5-6 mg) benefit most children, with higher doses offering marginal additional sleep improvement.
Area of Science:
- Pediatric Neurology
- Sleep Medicine
- Pharmacology
Background:
- Limited evidence exists on optimal melatonin dosage for pediatric sleep disturbances.
- Neurodevelopmental disorders often co-occur with significant sleep issues.
Purpose of the Study:
- To evaluate the efficacy and safety of melatonin in children with neurodevelopmental disorders and sleep disturbances.
- To determine effective melatonin doses for improving specific sleep parameters.
Main Methods:
- A cohort of 45 children with neurodevelopmental disorders received melatonin with dose adjustments based on response.
- Sleep diaries were used to track sleep onset delay, total sleep hours, and nighttime awakenings.
Main Results:
- Melatonin significantly improved total sleep hours, reduced sleep onset delay, and decreased nighttime awakenings (p=0.001).
- Low (2.5-3 mg) and medium (5-6 mg) doses were effective for 38% and 31% of children, respectively.
- No serious adverse events were reported during treatment.
Conclusions:
- Melatonin is a safe and effective treatment for sleep disturbances in children with neurodevelopmental conditions.
- Doses exceeding 6 mg/night provided additional benefits for only a small subset of patients.
Background:
Although melatonin is increasingly used for sleep disturbances in children with neurodevelopmental disorders, evidence on effective dose and impact on specific types of sleep disturbance is limited.
Method:
We assessed 45 children (35 males, mean age: 6.3 ± 1.7 years) with neurodevelopmental disorders (n = 29: intellectual disability; n = 9: autism spectrum disorder; n = 7: attention-deficit/hyperactivity disorder) and sleep disturbances, treated with melatonin (mean duration: 326 days) with doses increased according to response.
Results:
Thirty-eight percent of children responded to low (2.5-3 mg), 31% to medium (5-6 mg) and 9% to high doses (9-10 mg) of melatonin, with a significant increase in total hours of sleep/night, decreased sleep onset delay and decreased number of awakenings/night (all: p = 0.001), as measured with sleep diaries. No serious adverse events were reported.
Conclusions:
Melatonin is generally effective and safe in children with neurodevelopmental conditions. Increasing above 6 mg/night adds further benefit only in a small percentage of children.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
