 OTC drugs play an important role in self-medication. OTC analgesic and antipyretic drugs are widely used in Japan. The present study aimed to survey the components of OTC drug package inserts for analgesic and antipyretic drugs and to evaluate the adverse event profiles using the Japanese Adverse Drug Event Report database (JADER). The JADER contains 430587 reports from between April 2004 and November 2016; a total of 750 reports of adverse events resulted from the use of OTC analgesic and antipyretic drugs. The safety signals were detected by the reporting odds ratio (ROR). The ROR values for “Skin & subcutaneous tissue disorders”, “Immune system disorders”, and “Hepatobiliary disorders” stratified by system organ class of the Medical Dictionary for Regulatory Activities (MedDRA) were 7.58 (6.56-8.76), 4.25 (3.51-5.14), and 2.35 (1.93-2.85), respectively. OTC analgesic and antipyretic drugs containing allylisopropylacetylurea (AIAU) exhibited a significantly high reporting ratio of “Skin & subcutaneous tissue disorders” compared with the drugs without AIAU. No difference in the reported incidence of “Hepatobiliary disorders” was found between the drugs with or without acetaminophen. Our results suggested that it was important to monitor patients who use OTC analgesic and antipyretic drug containing AIAU; in particular, careful attention should be paid to skin and subcutaneous tissue disorders.
