What Is Tobradex?
Tobradex® (tobramycin and dexamethasone) is a prescription eye medication. It contains both an antibiotic and a steroid. It is approved for treating certain eye conditions that involve both inflammation and an infection (or a risk for an infection).
Tobradex is manufactured by Alcon Laboratories, Inc.
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.
