Contraindications
Hypersensitivity to any components of the product
Ocular or periocular infection
Patients with glaucoma, who have cup to disc ratios of greater than 0.8
Aphakic eyes with rupture of the posterior lens capsule

Cautions
Intravitreal injections have been associated with endophthalmitis, eye inflammation, increased IOP, and retinal detachments; monitor patients following the injection
Use of corticosteroids may produce posterior subcapsular cataracts, increased IOP, and glaucoma, and may enhance the establishment of secondary ocular infections caused by bacteria, fungi, or viruses
Use cautiously in patients with a history of ocular herpes simplex; reactivation of viral infection possible; Not for use in presence of active ocular herpes simplex
May mask infections or enhance existing infections
Pregnancy and lactation
Pregnancy category: C
Lactation: Unknown whether ocular administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in breast milk, caution advised
Pregnancy categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA: Information not available.
Pharmacology of Ozurdex (dexamethasone intravitreal implant)
Mechanism of action
Dexamethasone, a potent corticosteroid, suppresses inflammation by inhibiting multiple inflammatory cytokines, resulting in decreased edema, fibrin deposition, capillary leakage, and migration of inflammatory cells
Absorption
Negligible systemic absorption
