Tobramycin/Dexamethasone is a combination used to treat which type of infections?

• A. Gram-negative infections such as Pseudomonas
• B. Viral conjunctivitis
• C. Fungal keratitis
• D. Allergic conjunctivitis

Answer: (A)

This combination pairs an antibiotic that is particularly active against Gram-negative bacteria with a corticosteroid to reduce inflammation. Tobramycin targets many Gram-negative organisms, including Pseudomonas, helping to eradicate the infection, while dexamethasone decreases the inflammatory response and associated symptoms. Viral conjunctivitis, fungal keratitis, and allergic conjunctivitis are not treated with this antibiotic/steroid mix; they require antivirals or antifungals, or anti-allergic therapies, respectively. Therefore, the best description is that it’s used for Gram-negative infections such as Pseudomonas.
