The frequency of melatonin use for insomnia in hospitalized patients is unknown. This study assessed temporal trends of melatonin use in the hospital and compared them with those of use of zopiclone and lorazepam. We performed a retrospective observational study over 6 years from January 2013 to December 2018 at two academic urban hospitals in Toronto, Canada. We abstracted pharmacy dispensing data and standardized rates of medication use by inpatient days. Melatonin use increased from almost none to more than 70 doses per 1,000 inpatient days during 2013-2018, while zopiclone use decreased by 20 doses per 1,000 inpatient days. Melatonin use was twice as high at one hospital and was higher on internal medicine and critical care. Overall use of the three medications increased by 25.7%, which mainly reflects a marked increase in melatonin use. Melatonin is likely being used in a proportion of patients who would not otherwise have received a sleep medication.
