Key takeaways
TobraDex (tobramycin/dexamethasone) and Gentak (gentamicin) are both prescription medications used to treat bacterial eye infections, but they have some key differences. TobraDex is a combination of an aminoglycoside antibiotic (tobramycin) and a corticosteroid (dexamethasone), which means it not only fights bacteria but also reduces inflammation. In contrast, Gentak contains only gentamicin, an aminoglycoside antibiotic, and does not have anti-inflammatory properties. TobraDex is available in both eye drop and ointment forms, while Gentak also comes in these forms but is noted for being more affordable. TobraDex requires more frequent dosing and shaking of the bottle before use, whereas Gentak's ointment form requires fewer doses per day but can be messier to apply. Additionally, TobraDex can raise eye pressure if used for more than 10 days, while Gentak may cause eye irritation or allergic reactions. Both medications should be used as directed by your healthcare provider to avoid complications and ensure effectiveness.
