[The importance of a DLMO-measurement when starting and stopping melatonin in minors]

Melatonin is used as a chronobiotic in the treatment of sleeping disorders to correct disturbances in the circadian rhythm, including in children and adolescents. dim light melatonin onset (DLMO) and the peak in plasma concentration of melatonin contribute to this circadian rhythm. International research shows that the number of prescriptions for melatonin among children and adolescents is increasing significantly. However, there appears to be little empirical research on the best way to taper and/or discontinue melatonin in this population.

To assess the available literature regarding the best way to taper and/or discontinue melatonin in minors with sleep problems, with or without autism spectrum disorder (ASD) or attention-deficit/hyperactivity disorder (ADHD).

A systematic review of the literature in the PubMed (Medline) and Embase databases.

Several effects of the melatonin therapy on sleep onset, sleep latency, sleep duration, sleep efficiency, and nocturnal activity disappear after discontinuation of the treatment. However, we cannot formulate evidence-based guidelines regarding treatment duration, timing of administration, dosage, or the method of discontinuation. DLMO prior to treatment does, however, have predictive value for the effect of discontinuing melatonin therapy.

A DLMO-measurement prior to starting melatonin treatment provides clinicians with insight into the expected effects of melatonin during therapy. This allows for an estimation of whether melatonin will have not only a soporific but also a chronobiotic effect during treatment. Based on this information, clinicians can consider whether initiating or discontinuing melatonin therapy is appropriate. Consequently, our literature review provides a strong argument for reimbursement of DLMO-measurements by health insurance funds.
