In a child with difficulty initiating and maintaining sleep, which medication is most commonly prescribed when pharmacologic therapy is considered?

• A. Melatonin
• B. Diphenhydramine
• C. Lorazepam
• D. Zolpidem

Answer: (A)

When considering pharmacologic therapy for a child with trouble starting and staying asleep, melatonin is the most commonly prescribed option. It acts on melatonin receptors in the brain to help adjust the sleep-wake cycle, making it easier for a child to fall asleep and often to maintain more consistent sleep across the night. This approach targets the circadian rhythm rather than simply sedating the child, which is why it’s favored in pediatric sleep difficulties and typically has a more favorable safety profile. Melatonin is generally used at the lowest effective dose and titrated as needed, with emphasis on good sleep hygiene and consistent routines to support lasting benefit. Other medications listed are less ideal in children: diphenhydramine can cause next-day drowsiness and anticholinergic effects; benzodiazepines like lorazepam carry risks of dependence and respiratory issues; zolpidem has safety concerns in pediatric populations and is not routinely recommended.
