How Does Tobradex Work?

Tobradex contains two active ingredients -- tobramycin and dexamethasone. Tobramycin belongs to a class of antibiotics known as aminoglycosides. Dexamethasone is a corticosteroid (often known simply as a "steroid") that works by decreasing inflammation.
Because dexamethasone also interferes with the body's defense mechanisms that fight off infections, it is often a good idea to use dexamethasone in combination with an antibiotic (such as tobramycin), especially if there is already an infection present or if there is a risk for infection.
