Uses of Dexamethasone + Neomycin
Dexamethasone + Neomycin is a combination medicine used to treat steroid-responsive inflammatory eye conditions where bacterial infection is present or there is a risk of bacterial infection.
This combination is commonly used for:
• Bacterial eye infections: Treats steroid-responsive inflammatory eye conditions associated with bacterial infection or a risk of bacterial infection.

Side effects of Dexamethasone + Neomycin
Stinging or burning sensation in the eye
Temporary blurred vision
Itching, redness, or swelling of the eyelids
Delays in wound healing with prolonged use
How Dexamethasone + Neomycin works
Dexamethasone + Neomycin works through two separate actions that reduce inflammation while controlling bacterial infection.
Dexamethasone is a corticosteroid. It reduces inflammation by blocking the production of substances that trigger an inflammatory response, easing redness and swelling.
Neomycin is an antibiotic. It attaches to bacterial ribosomes, disrupting protein production, which stops susceptible bacteria from growing and multiplying.
Together, Dexamethasone reduces inflammation while Neomycin controls bacterial growth, managing conditions where both infection and inflammation are present.
