Most Common Inpatient Sleep Medication for Children and Adolescents
Melatonin is the most commonly prescribed medication for sleep in hospitalized children and adolescents, accounting for approximately 70% of new sleep medication prescriptions in the inpatient setting.
Evidence from Inpatient Practice
The strongest real-world evidence comes from a 2023 retrospective study of hospitalized patients, which found that melatonin was administered in 70.5% of cases when new sleep medications were prescribed, far exceeding benzodiazepines (9.6%) and other agents 1. This aligns with recent prescription pattern data showing melatonin comprises 33.9% of first-time hypnotic prescriptions overall in pediatric populations, with even higher utilization in younger age groups 2.
Why Melatonin Dominates Inpatient Use
Several factors explain melatonin's predominance:
- Safety profile: Lacks the adverse reactions and drug interactions associated with benzodiazepines and Z-drugs 1
- Age appropriateness: Particularly favored for children aged 0-11 years 2
- Guideline support: American Academy of Sleep Medicine guidelines recommend melatonin for children and adolescents with delayed sleep-wake phase disorder, with moderate-quality evidence 3
- Efficacy in special populations: Proven effective in children with autism spectrum disorders and ADHD, common comorbidities in hospitalized children 4
Dosing Patterns in Clinical Practice
For children without comorbidities: 0.15 mg/kg administered 1.5-2 hours before bedtime shows optimal results 3
For children with psychiatric comorbidities (ADHD, autism): 3-5 mg based on weight (3 mg if <40 kg; 5 mg if >40 kg) 3
For sedative effect: Higher doses (1 mg in infants, 2.5-3 mg in older children, 5 mg in adolescents) given 30 minutes before bed 5
Alternative Agents (Less Common)
While melatonin dominates, other medications are occasionally used:
- Antihistamines (diphenhydramine, hydroxyzine): Often first-line historically but limited efficacy data and tolerance development 5. Recent data shows hydroxyzine accounts for only a small fraction of prescriptions 6
- Benzodiazepines and Z-drugs: Used in <10% of cases due to concerns about reduced clearance in children, compounded sedative effects, and potential for sleep architecture disruption 1
- Melatonin receptor agonists: Emerging use (30.9% of prescriptions) particularly across all age groups 2
Critical Caveats
Important limitations: Long-term safety data for melatonin in children remain lacking, and the benefits/harms assessment is uncertain 3. Informed consent from patients and caregivers is essential.
Avoid in specific contexts: Benzodiazepines and Z-drugs should be used cautiously given their reduced clearance in pediatric populations and potential for adverse effects that may outweigh sleep benefits in the hospital setting 1.
Post-pandemic surge: Prescription rates have increased dramatically since 2020, with melatonin prescriptions exceeding expected rates by 344% 6, reflecting both increased sleep disturbances and changing prescribing patterns.
