Avoid prolonged treatment as it may lead to systemic corticosteroid effects even withour occlusion. Avoid prolonged excessive application to the facial areas. Withdraw treatment if there is spread of the infection. Risk of glaucoma development if preparation enters eye(s). Regular monitoring is recommended when used in psoriasis due to treatment tolerance, rebound relapses, generalised pustular psoriasis or systemic toxicity. Increased risk of contact sensitisation when used for extended period or recurrently. Pregnancy and lactation. Ophthalmic preparation: Monitor intraocular pressure, cataract formation of unsuspected infections; evaluate treatment if there is no clinical improvement after 7 days. Not to be used for undiagnosed red eye.
