The effectiveness of diphenhydramine HCI in pediatric sleep disorders.

Fifty children with a variety of sleep disorders were studied in a placebo-controlled, double-blind clinical trial of diphenydramine elixir given in a dosage of 1.0 mg/kg at bedtime. Sleep records measuring latency time, number of awakenings, and duration of sleep were compiled by the patient's parent. A global assessment as to the severity of sleep disturbance and the therapeutic effect of the medication and placebo was made on a weekly basis. Diphenhydramine was significantly better than placebo in reducing sleep latency time and the number of awakenings per night, while sleep duration was marginally increased. There were no essential differences between diphenhydramine and placebo in the other study parameters, i.e., restlessness, nightmares, and difficulty awakening. Diphenhydramine was judged to be more effective than placebo on the weekly global assessment. The results indicate that diphenhydramine is a safe, effective bedtime sleep aid for pediatric patients.
