Abstract
Gentamicin is one of the aminoglycosides that is used mainly to treat Gram-negative infections. It is important to know trends in outpatient gentamicin prescriptions and to know the difference in prescribing of it according to age and gender. The goal of this study is to describe the patterns of topical gentamicin prescribing and to describe the age and gender differences in its prescribing. This is a retrospective study conducted in a public hospital in Alkharj, Saudi Arabia. The study includes electronic files and outpatient prescriptions review for the patients who received topical gentamicin. It can be concluded that gentamicin was prescribed equally for males and females mainly for younger patients. Most of the prescriptions were written by residents of the emergency department. It is important to prescribe and dispense gentamicin appropriately to increase its efficacy and to instruct patients on proper instillation technique.
