How Supplied


For steroid-responsive inflammatory ocular conditions for which a corticosteroid is indicated and where bacterial infection or a risk of bacterial ocular infection exists.

Ocular steroids are indicated in inflammatory conditions of the palpebral and bulbar conjunctiva, cornea, and anterior segment of the globe where the inherent risk of steroid use in certain infective conjunctivitides is accepted to obtain a diminution in edema and inflammation. They are also indicated in chronic anterior uveitis and corneal injury from chemical, radiation, or thermal burns, or penetration of foreign bodies.

The use of a combination drug with an anti-infective component is indicated where the risk of infection is high or where there is an expectation that potentially dangerous numbers of bacteria will be present in the eye.

The particular anti-infective drug in this product is active against the following common bacterial eye pathogens:

Staphylococcus aureus
Escherichia coli

Haemophilus influenzae


The product does not provide adequate coverage against:

Pseudomonas aeruginosa
Serratia marcescens

Streptococci, including Streptococcus pneumoniae


The duration of treatment will vary with the type of lesion and may extend from a few days to several weeks, according to therapeutic response.

Instill one or two drops of Ophthalmic Solution NEODECADRON (neomycin and dexamethasone) into the conjunctival sac every hour during the day and every two hours during the night as initial therapy. When a favorable response is observed, reduce dosage to one drop every four hours. Later, further reduction in dosage to one drop three or four times daily may suffice to control symptoms.

Not more than 20 milliliters should be prescribed initially and the prescription should not be refilled without further evaluation as outlined in PRECAUTIONS above.
