Compare Tobrex vs. Tobradex

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Tobrex (tobramycin) and Tobradex (tobramycin/dexamethasone) are both used to treat bacterial eye infections, but they have some key differences. Tobrex is an aminoglycoside antibiotic that fights bacterial infections by blocking protein production and damaging the bacteria's protective covering. It comes in both eye drops and ointment forms and is available as a generic. Tobradex, on the other hand, combines tobramycin with dexamethasone, a corticosteroid that reduces inflammation. This combination makes Tobradex effective not only for bacterial infections but also for reducing eye inflammation. However, Tobradex requires careful monitoring if used for more than 10 days due to the risk of increased eye pressure and other side effects. Unlike Tobrex, Tobradex must be shaken before use. Both medications require a prescription and should be used as directed by your healthcare provider.
