As with all antibacterial preparations, prolonged use may lead to overgrowth of non-susceptible bacterial strains or fungi. If superinfection occurs, appropriate therapy should be initiated.

Serious adverse reactions including neurotoxicity, ototoxicity and nephrotoxicity have occurred in patients receiving systemic neomycin or when applide topically to open wounds or damaged skin nephrotoxic and neurotoxic reaction have also occurred with systemic polymyxin B although these effects have not been reported following topical ocular use of this product caution is advised when used concomitantly with systemic aminoglycosid or polymyxin B therapy . Prolonged use of ophthalmic steroids may result In ocular hypertension and/or glaucoma with damage to the optic nerve reduced visual ocuity and visual field defects and posterior subcapsular cataract formation in patients receiving prolonged ophthalmic corticosteroid therapy intraocular pressure should be checked routinely and frequently in those diseases causing thinning of the cornea or sclera perforations have been known to occur with the use of topical corncosteroids.
Corticosteroids may reduce resistance to and aid in the establishment of bacterial, viral, or fungal infections and mask the clinical signs of infection, preventing recognition of ineffectiveness of the antibiotic. or may suppress hypersensitivity reactions to substances in the product. Fungal infection should be suspected in patients with persistent corneal ulceration who have been or are receiving these drugs and corticosteroid therapy should be discontinued if fungal infection occurs to avoid the risk of enhancement of herpetic corneal disease frequent slit lamp examination is essential.
Contact lens wear is not recommended during treatment of an ocular infection. Therefore patient should be advised not to wear contact lenses during treatment with dexatrol cause eye irritation and is known to discolour soft contact lenses. Avoid contact with soft Contact lenses. Remove contact lenses prior to application and wait at least 15 minutes before reinsertion.

Topical ophthalmic steroid use may result in Increased intraocular pressure with damage to the optic nerve, reduced visual acuity and visual field defects. Also it may lead to posterior subcapsular cataract formation (See Section Special Warnings and Precautions for use). Sensitivity to topically-administered aminoglycosides may occur in some patients (See Section Special Warnings and Precautions for use). Systemic side effects may occur with extensive use.

Dexamethasone, like other corticosteroids, is absorbed rapidly after oral administration and has a biological half-life of about 190 minutes. Sufficient absorption may occur after topical application to the skin and eye to produce systemic effects. Intraocular penetration of dexamethasone occurs in significant amounts and contributes to the effectiveness or dexamethasone in anterior segment polymyxin B sulphate is not absorbed from the gastrointestinal tract or through intact skin, although the intact corneal epithelium prevents penetration into the corneal stroma, therapeutic concentrations do enter the stroma after epithelial damage. Good stromal penetration occurs after epithelial abrasion following topical instillation. subconjunctival Injection, or corneal bath. No significant polymyxin B penetration into the vitreous is demonstrable after parenteral or local administration af the drug neomycin is poorly absorbed from the gastrointestinal trac and after topical administration an insufficient amount is absorbed to produce systemic effects. Absorption has been reported to occur from wounds and inflamed skin. After absorption neomycin is rapidly excreted by the kidneys in active form.
