MAXIDEX

INDICATIONS AND USAGE Steroid responsive inflammatory conditions of the palpebral and bulbar conjunctiva, cornea, and anterior segment of the globe, such as allergic conjunctivitis, acne rosacea, superficial punctate keratitis, herpes zoster keratitis, iritis, cyclitis, selected infective conjunctivitides when the inherent hazard of steroid use is accepted to obtain an advisable diminution in edema and inflammation; corneal injury from chemical, radiation, or thermal burns, or penetration of foreign bodies.

DOSAGE AND ADMINISTRATION SHAKE WELL BEFORE USING. One or two drops topically in the conjunctival sac(s). In severe disease, drops may be used hourly, being tapered to discontinuation as the inflammation subsides. In mild disease, drops may be used up to four to six times daily. Not more than one bottle should be prescribed initially, and the prescription should not be refilled without further evaluation as outlined in PRECAUTIONS above.

CONTRAINDICATIONS Contraindicated in acute, untreated bacterial infections; mycobacterial ocular infections; epithelial herpes simplex (dendritic keratitis); vaccinia, varicella, and most other viral diseases of the cornea and conjunctiva; fungal disease of ocular structures; and in those persons who have shown hypersensitivity to any component of this preparation.

WARNINGS Prolonged use may result in ocular hypertension and/or glaucoma, with damage to the optic nerve, defects in visual acuity and fields of vision, and posterior subcapsular cataract formation. Prolonged use may suppress the host response and thus increase the hazard of secondary ocular infections. In acute purulent conditions or parasitic infections of the eye, corticosteroids may mask infection or enhance existing infection. In those diseases causing thinning of the cornea or sclera, perforations have been known to occur with the use of topical corticosteroids. If these products are used for 10 days or longer, intraocular pressure (IOP) should be routinely monitored even though it may be difficult in children and uncooperative patients. Employment of corticosteroid medication in the treatment of herpes simplex other than epithelial herpes simplex keratitis, in which it is contraindicated, requires great caution; periodic slit-lamp microscopy is essential.

ADVERSE REACTIONS Glaucoma with optic nerve damage, visual acuity and field defects; cataract formation; secondary ocular infection following suppression of host response; and perforation of the globe may occur. Clinical Studies Experience In clinical studies with MAXIDEX, the most frequently reports adverse reactions were ocular discomfort occurring in approximately 10% of the patients and eye irritation occurring in approximately 1% of the patients. All other adverse reactions from these studies occurred with a frequency less than 1%, including keratitis, conjunctivitis, dry eye, photophobia, blurred vision, eye pruritis, foreign body sensation, increased lacrimation, abnormal ocular sensation, eyelid margin crusting, and ocular hyperemia. Postmarketing Experience Additional adverse reactions identified from post-marketing use include corneal erosion, dizziness, eye pain, eyelid ptosis, headache, hypersensitivity reactions, and mydriasis. Frequencies cannot be estimated from the available data. The following additional adverse reactions have been reported with dexamethasone use: Cushing's syndrome and adrenal suppression may occur after use of dexamethasone in excess of the listed dosing instructions in predisposed patients, including children and patients treated with CYP3A4 inhibitors.

Pregnancy Dexamethasone has been shown to be teratogenic in mice and rabbits following topical ophthalmic application in multiples of the therapeutic dose. In the mouse, corticosteroids produce fetal resorptions and a specific abnormality, cleft palate. In the rabbit, corticosteroids have produced fetal resorptions and multiple abnormalities involving the head, ears, limbs, palate, etc. MAXIDEX (dexamethasone ophthalmic suspension) 0.1% should be used during pregnancy only if the potential benefit to the mother justifies the potential risk to the embryo or fetus. There are no adequate or well-controlled studies in pregnant women. However, prolonged or repeated corticoid use during pregnancy has been associated with an increased risk of intra-uterine growth retardation. Infants born of mothers who have received substantial doses of corticosteroids during pregnancy should be observed carefully for signs of hypoadrenalism.
