Oseltamivir
Oseltamivir, used in influenza, causes rare hypersensitivity reactions although close monitoring of patients is important as 2 cases with Stevens-Johnson syndrome (SJS)/Toxic epidermal necrolysis (TEN) have been reported (46,47), with only one being confirmed by LTT (47). Another case report revealed anaphylaxis due to oseltamivir confirmed by a skin prick test (SPT) (65).
