The prescribing of low doses of quetiapine for the treatment of sleeping disorders appears to be widespread. Recently, in a systematic literature review on low-dose quetiapine use for the treatment of sleeping disorders, it was concluded that evidence for its efficacy is currently lacking. Furthermore, quetiapine is probably associated with potentially severe adverse effects, also at low doses. In conclusion, sufficient scientific evidence that justifies the current practice of off-label prescribing of low-dose quetiapine for the treatment of sleeping disorders is insufficient; further research into its efficacy and safety is needed.
