Epithelial herpes simplex keratitis (dentritic keratitis), vaccinia, varicella, and many other viral diseases of the cornea and conjunctiva. Hypersensitivity to a component of the medication (Hypersensitivity to the antibiotic component occurs at a higher rate than other component).

The use of these combinations is always contraindicated after uncomplicated removal of a corneal foreign body.

Side effects:

Adverse reactions have occurred with steroid/anti-infective combination drugs which can be attributed to the steroid component, the anti-infective component, or the combination. Exact incidence figures are not available since no denominator of treated patients is available. Reactions occurring most often from the presence of the anti-infective ingredient are allergic sensitizations. The reactions due to the steroid component in decreasing order of frequency are: elevation of intraocular pressure (IOP) with possible development of glaucoma, and infrequent optic nerve damage, posterior sub-capsular cataract formation and delayed wound healing.
