Tobradex ophthalmic suspension

Tobramycin and Dexamethasone Ophthalmic Suspension: Triple-Action Eye Drops

This ophthalmic suspension (commonly known by the brand name Tobradex) is a combination of a potent aminoglycoside Antibiotic (Tobramycin) and a strong Corticosteroid (Dexamethasone). While originally approved for human use, it is frequently used by veterinarians on an extra-label basis for dogs, cats, and horses. The suspension form is often preferred for its ease of application and its ability to distribute the medication evenly across the surface of the eye to combat both bacterial infection and significant inflammation simultaneously.

Prescription Required

Tobramycin and Dexamethasone Ophthalmic Suspension is a prescription-only medication. A valid prescription from a licensed veterinarian is required for purchase.

Critical Safety Warning: Because this medication contains a corticosteroid, it must never be used in an eye that has a corneal ulcer or scratch. Dexamethasone prevents the cornea from healing and can lead to rapid "melting" of the cornea or eye rupture. A veterinarian must confirm the eye surface is intact using a fluorescein stain test before this medication is prescribed or refilled. It should also be used with caution in cats, as they are more susceptible to certain viral flare-ups (like Feline Herpesvirus) when using topical steroids.
