Most of the suspected DHRs were of non\u2010immediate (<jats:italic>n<\/jats:italic>\u00a0=\u00a016, 66.6%) type, and the offending drugs were amoxicillin\u2010clavulanic acid (<jats:italic>n<\/jats:italic>\u00a0=\u00a07), macrolides (<jats:italic>n<\/jats:italic>\u00a0=\u00a04), trimethoprim\u2010sulfamethoxazole (TMP\/SMX) (<jats:italic>n<\/jats:italic>\u00a0=\u00a02), piperacillin\u2010tazobactam (<jats:italic>n<\/jats:italic>\u00a0=\u00a01), pancrelipase (<jats:italic>n<\/jats:italic>\u00a0=\u00a01), and ursodeoxycholic acid (<jats:italic>n<\/jats:italic>\u00a0=\u00a01).
