Abstract: Objective To mine and analyze signals of adverse reactions due to the combined use of immunosuppressive agents tacrolimus and voriconazole by using the FDA ( Food and Drug Administration) adverse event reporting system (FAERS) and to provide reference for clinical combined medication. Methods Adverse event reports related to tacrolimus and voriconazole collected in the FAERS database between January 1, 2010 and December 31, 2019 were retrieved using measures of disproportionality. The reporting odds ratio (ROR) and proportional reporting ratio (PRR) were used to compare the suspected adverse reaction signals of tacrolimus and voriconazole used alone or in combination. Adverse reactions that arose from the combination of the two drugs were compared with those specified in the instructions of the two drugs in order to screen out new adverse reactions. Results A total of 52 572 adverse reaction reports of tacrolimus, 8 789 adverse reaction reports of voriconazole, and 1 229 adverse reaction reports of tacrolimus combined with voriconazole were retrieved. When the combined use of the two drugs was compared to tacrolimus used alone, it was found that there were 84 adverse reactions, both ROR and PRR of which were greater than 2, compared with 56 adverse reactions for voriconazole. Compared with the adverse reactions specified in instructions of tacrolimus and voriconazole, there were 6 new adverse reactions involved. Conclusion The combination of tacrolimus and voriconazole may induce far more adverse reactions than single use, which deserves clinical attention.
