What Experts Say

Tobramycin is an aminoglycoside antibiotic that works by binding to bacterial ribosomes and blocking protein synthesis. This action makes it bactericidal against many gram negative organisms and several gram positive species that commonly cause external eye infections. Its broad coverage explains why it is paired with a steroid in combination ointments for infected, inflamed eyes.

Dexamethasone is a potent corticosteroid that suppresses the inflammatory response by reducing capillary dilation, cellular infiltration, and fibrin deposition in ocular tissue. This calms redness, swelling, and discomfort faster than an antibiotic alone. Steroids should only be added once bacterial infection is confirmed or strongly suspected, since they can mask worsening infection if used inappropriately.

Combination therapy is appropriate for short, defined courses under medical supervision. Prolonged steroid use in the eye can raise intraocular pressure and increase cataract risk, so follow up is advised if treatment extends beyond the prescribed duration. Screening for viral or fungal eye infections before starting is essential, since steroids can worsen these conditions significantly.

• Avoid touching the tube tip to the eye or any surface
• Close the eye gently for one to two minutes after applying
• Continue for the full prescribed duration even if symptoms improve

Drug Interactions

• Other Topical Eye Medications: Space other eye drops or ointments five to ten minutes apart to avoid a diluting effect
• Other Corticosteroid Eye Products: Avoid combining with additional steroid ophthalmic products unless directed, due to added pressure risk
• Contact Lenses: Avoid wearing soft contact lenses during active infection and steroid treatment
• Live Vaccines: The steroid component may reduce immune response if meaningful systemic absorption occurs, though ocular absorption is normally minimal

Risks and warnings

• Prolonged Use: Extended use can raise intraocular pressure and increase cataract risk
• Infection Masking: The steroid component can mask signs of worsening bacterial, fungal, or viral infection
• Viral Eye Infections: Avoid use in active herpes simplex keratitis and other viral corneal infections
• Fungal Infections: Not suitable for fungal eye infections since steroids can worsen fungal growth
