Antidepressant Medication Use and Development of Hyperglycemia and Diabetes Mellitus: A Japanese Adverse Drug Event Report Database Study

Few studies have examined the relationship between the use of antidepressants and the onset of hyperglycemia and diabetes mellitus in Japan. We herein explored the possibility of this relationship using the Japanese Adverse Drug Event Report database (JADER). The present study included 20 individual antidepressants, consisting of 6 subclasses, which have been approved for use in Japan. We used Standardized MedDRA Queries 20000041 to extract patients who developed hyperglycemia/new onset diabetes mellitus (NODM) in JADER between April 2004 and September 2016. We calculated reporting odds ratios (RORs) with 95 % confidence intervals (CI). We also calculated odds ratios defined as the ratio of odds of hyperglycemia/NODM to all other adverse drug events (ADEs) by the age cut-off group or sex in the cases of antidepressants. The lower limit of 95% CI of RORs for 13 antidepressants (imipramine, clomipramine, nortriptyline, amitriptyline, amoxapine, maprotiline, mianserin, sertraline, paroxetine, escitalopram, duloxetine, mirtazapine, and trazodone), which included all subclasses, exceeded 1. Younger age group was associated with hyperglycemia/NODM for 5 antidepressants (imipramine, amitriptyline, maprotiline, duloxetine, and trazodone), and female was associated with the ADEs for trazodone, although these results should be interpreted cautiously. Healthcare personnel need to be aware that the use of antidepressants may lead to hyperglycemia/NODM.
