The dogma of gentamicin ototoxicity theorizes that (1) the toxic effects of the drug are cumulative and dose dependent, despite clinical observations of ototoxicity after a single dose, and (2) gentamicin's ototoxic effects are irreversible, although clinicians have observed improvement in hearing over time. Across all the included studies, 24 107 participants received a single one‐off dose of gentamicin (doses ranged from 1 mg kg –1 to 480 mg per dose).
