“…In patients sensitized to neomycin, the percentage of cross-reactions to other aminoglycoside antibiotics is high: to paromomycin and butirosin 106 approximately 90%, to framycetin 70%, to ribostamycin 70%, 107 to tobramycin and kanamycin 60%, to gentamicin 50%, to amikacin 30%, 108 and to sisomicin 109 20% 2 . However, streptomycin cross-reacts (or coreacts more likely) in only approximately 4% of the patients 2,107,109 .…”
