Ophthalmic ointment [Canadian product]: Gently pull down under eye to form pocket between eyeball and lower eyelid, then apply ointment into pocket; patient should look down prior to closing eye. Do not touch tip of dropper to eye(s) or any other surface.
Ophthalmic solution, suspension: Remove soft contact lenses prior to using solutions containing benzalkonium chloride. Do not touch tip of container to eye. Shake suspension well prior to use.
Ophthalmic solution may also be administered otically. Prior to use, clean the aural canal thoroughly and sponge dry.
Ophthalmic implant (intravitreal injection): Administer under controlled aseptic conditions (eg, sterile gloves, sterile drape, sterile eyelid speculum). Administer adequate anesthesia and a broad-spectrum bactericidal to the periocular skin, eyelid, and ocular surfaces prior to injection. Refer to manufacturer’s prescribing information for administration technique. If administration is required in the second eye, a new applicator should be used and the sterile field, syringe, gloves, drapes, and eyelid speculum should be changed.
Ocular implant, ophthalmic solution: Store at 15°C to 30°C (59°F to 86°F).
Ophthalmic ointment [Canadian product]: Store at room temperature.
Ophthalmic suspension: Store at 8°C to 27°C (46°F to 80°F).
Ceritinib: Corticosteroids may enhance the hyperglycemic effect of Ceritinib. Monitor therapy
NSAID (Ophthalmic): May enhance the adverse/toxic effect of Corticosteroids (Ophthalmic). Healing of ophthalmic tissue during concomitant administration of ophthalmic products may be delayed. Monitor therapy
Intravitreal implant (Ozurdex):
Cardiovascular: Hypertension (13%)
Ophthalmic: Cataract (5% to 68%; incidence increases in patients requiring a second injection), increased intraocular pressure (25%; ≥10 mm Hg: 28%; ≥30 mm Hg: 15%), conjunctival hemorrhage (22% to 23%)
1% to 10%:
Cardiovascular: Aneurysm (3%; retinal)
Central nervous system: Headache (4%), foreign body sensation of eye (2%)
Ophthalmic: Decreased visual acuity (9%), eye pain (8%), conjunctival hyperemia (7%), conjunctivitis (6%), conjunctival edema (5%), dry eye syndrome (5%), ocular hypertension (5%), vitreous opacity (3% to 5%), vitreous detachment (4%), anterior chamber inflammation (2%), blepharoptosis (2%), corneal erosion (2%), keratitis (2%), retinal hole without detachment (2%)
Respiratory: Bronchitis (5%)
Postmarketing and/or case reports (Limited to important or life-threatening): Corneal edema, decreased intraocular pressure, endophthalmitis, retinal detachment
Ophthalmic solution/suspension: Frequency not defined: Ophthalmic: Burning sensation of eyes, cataract, decreased visual acuity, eye perforation, filtering blebs, glaucoma (with optic nerve damage), secondary ocular infection, stinging of eyes, visual field defect
Concerns related to adverse effects:
• Immunosuppression: Prolonged use may increase the hazard of secondary ocular infections. May mask infection or enhance existing infection. The possibility of persistent corneal fungal infection should be considered after prolonged use. Corticosteroids should not be used to treat ocular herpes simplex; use caution in patients with a history of ocular herpes simplex; reactivation of viral infection may occur.
• Ocular effects: Avoid prolonged use, which 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. Hypotony of the eyes have also been reported with the implant, some of which were serious. Monitor intraocular pressure if topical ophthalmic products are used for 10 days or longer.
• Ocular disease: Perforations may occur in diseases which cause thinning of the cornea or sclera.
• Contact lens wearers: Ophthalmic solution and suspension contain benzalkonium chloride which may be absorbed by contact lenses; contact lens should not be worn during treatment of ophthalmic infections.
Dosage form specific issues:
• Intravitreal implant: Endophthalmitis, ocular inflammation, intraocular pressure elevations and retinal detachments may occur with intravitreal injection. Intraocular pressure elevations peak ~8 weeks following injection; prolonged monitoring of intraocular pressure may be required. A risk of implant migration into the anterior chamber may be present if the posterior capsule of the lens is absent or torn. Temporary blurring may occur following intravitreal injections; patients should not drive until this resolves. Administer adequate anesthesia and a broad-spectrum microbicide prior to procedure.
• Intravitreal implant (Canadian labeling): For macular edema following CRVO, no more than two consecutive injections should be used, and an interval of ~6 months should be allowed between the two injections. In patients with posterior segment uveitis, the use of a second injection is not recommended. Caution should be exercised if a second injection is considered in cases where the possible benefits are believed to outweigh the risk to the patient; ~6 months should be allowed between the two injections. Patients who experience and retain improved vision and patients who experience a deterioration in vision, which is not slowed by dexamethasone implant, should not be re-treated. Repeat doses should only be considered when a patient experiences a response to treatment followed subsequently by a loss in visual acuity and may benefit from re-treatment. Not recommended in patients with macular edema secondary to RVO with significant retinal ischemia. Administration to both eyes is not recommended. Use with caution in aphakic patients.
Ophthalmic solution/suspension: Intraocular pressure (with use >10 days)
Ophthalmic implant (intravitreal injection): Following injection, monitor for increased intraocular pressure and endophthalmitis; check for perfusion of optic nerve head immediately after injection, tonometry within 30 minutes, biomicroscopy between 2-7 days after injection.
Pregnancy Risk Factor
Adverse events were observed in animal reproduction studies following use of ophthalmic dexamethasone.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience foreign body sensation, dry eyes, or blurred vision. Have patient report immediately to prescriber vision changes, eye pain, severe ear irritation, eye redness, sensitivity to light, vitreous floaters, cough that does not go away, severe dizziness, severe headache, or severe eye irritation (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
