Tobramycin + Dexamethasone Tobradex is a combination eye drop of the aminoglycoside tobramycin with the corticosteroid dexamethasone, used for eye inflammation where bacterial infection is present or likely.
- Antibiotic and steroid in one eye drop
- Unusually good Pseudomonas coverage for a topical
- Dexamethasone suppresses inflammation that threatens vision
- In the right eye it saves vision
- Covers bacterial infection while calming the eye
Mechanism
Tobramycin binds the bacterial 30S ribosome and blocks protein synthesis, with unusually good Pseudomonas coverage for a topical agent, while dexamethasone suppresses the response that causes swelling and corneal scarring. Steroid antibiotic pairs are reserved for cases where the inflammation itself threatens vision, which is also why a missed herpetic keratitis becomes serious so fast.
Safetyrisks and cautions, not medical advice
a corticosteroid plus an aminoglycoside; the steroid raises intraocular pressure with prolonged use and makes herpetic or fungal keratitis considerably worse
Subjective profileweighing the evidence above
This is the one eye drop that should never sit in a household cabinet waiting for the next red eye. Dexamethasone suppresses inflammation and the warning symptoms along with it, so a herpetic keratitis can quietly eat through the cornea while the eye feels better by the day; that scenario, not the antibiotic, is why the combination is prescription only. Prolonged use also raises intraocular pressure in steroid responders, who have no way of knowing they are one without a pressure check. In the right eye it saves vision, which is exactly why it needs someone who has put that cornea under a slit lamp first.
