Tobracin D 3.5 gm is a topical eye ointment used to treat inflammatory ocular conditions where a bacterial infection is present or likely. It is indicated for conditions such as conjunctivitis, corneal injuries, and chronic anterior uveitis. The combination of tobramycin and dexamethasone provides both antibacterial and anti-inflammatory effects, making it effective in managing eye infections with associated inflammation. The typical dosage involves applying a small amount into the conjunctival sac 3–4 times per day, with the frequency potentially increased during the initial 24–48 hours. As with all medications, it is essential to follow the prescribed dosage and consult a healthcare provider before discontinuing or adjusting the medication
