Side Effects

Hypersensitivity reactions may occur leading to irritation, burning, stinging, itching and dermatitis. Topical corticosteroid use may result in corneal ulceration, increased intraocular pressure leading to optic nerve damage, reduced visual acuity.Intensive or prolonged use of topical corticosteroids may lead to formation of posterior subcapsular cataracts. In those diseases causing thinning of the cornea or sclera, corticosteroid therapy may result in thinning of the globe leading to perforation. Mydriasis, ptosis and epithelial punctate keratitis have also been reported following ophthalmic use of corticosteroids


Topical corticosteroids should never be given for an undiagnosed red eye. Ophthalmic treatment with corticosteroid preparations should not be repeated or prolonged without regular review to exclude raised intraocular pressure, cataract formation or unsuspected infections

Pregnancy & Breastfeeding use

Viral, fungal, tuberculous or purulent conditions. Use in the eye is contra-indicated if glaucoma is present or where herpetic keratitis (e.g. dendritic ulcer) is considered a possibility. Inadvertent use of topical steroids in the latter condition can lead to extension of the ulcer and marked visual deterioration. Preparations containing neomycin should not be used for treating otitis externa when the ear drum is perforated, because of the risk of ototoxicity.
