Key takeaways
Moxifloxacin (Vigamox) and Tobradex (tobramycin/dexamethasone) are both prescription eye medications, but they have different uses and components. Moxifloxacin (Vigamox) is a fluoroquinolone antibiotic used to treat bacterial conjunctivitis (pink eye) and is available in both brand-name and generic forms. It works by blocking proteins that bacteria need to grow and survive. You need to use it three times a day for seven days. Common side effects include dry eye, eye pain, and redness. On the other hand, Tobradex (tobramycin/dexamethasone) is a combination of an aminoglycoside antibiotic and a corticosteroid. It treats bacterial eye infections and reduces inflammation. Tobradex is available as eye drops and ointment, and you typically use it every 4 to 6 hours.Tobradex is also availible in a generic form. It can raise eye pressure if used for more than 10 days and may cause side effects like eye irritation and swollen eyelids. Unlike Moxifloxacin, Tobradex also helps with eye inflammation, making it useful for conditions where both infection and inflammation are present.
