Abstract: Objective To analyze benzodiazepines-related signals based on the data (1Mar2004-30Sep2020) from the Food and Drug Administration Adverse Event Reporting System (FAERS), and to screen lorazepam a second time in order to contribute to rational use of the drug. Methods Using the frequency method, benzodiazepines-related signals were mined via the Chi-Squared test with Yates’ correction ( χ2Yates ), proportional reporting ratio (PRR) and the lower limit of the 95% confidence interval of the reporting odds ratio (ROR025). Results The number of signals related to alprazolam, clobazam, clonazepam, clorazepate, diazepam, estazolam, flurazepam, lorazepam, oxazepam, quazepam, temazepam and triazolam was 1 345, 582, 1 532, 430, 1 430, 216, 312, 1 699, 618, 98, 1 027 and 330, respectively. Fifty-eight signals were obtained by the second analysis of lorazepam. Conclusion Most of the top 10 benzodiazepine-related signals have been described in drug labels, but most of the lorazepam-related signals mined in the second analysis have not been described in drug labels, so more attention should be paid to such signals in the subsequent use of lorazepam to reduce the side effects of the drug.
