DOSAGE AND ADMINISTRATION Dexamethasone sodium phosphate injection, 10 mg/mL– For intravenous and intramuscular injection only. Dexamethasone sodium phosphate injection can be given directly from the vial, or it can be added to Sodium Chloride Injection or Dextrose Injection and administered by intravenous drip. Solutions used for intravenous administration or further dilution of this product should be preservative free when used in the neonate, especially the premature infant. When it is mixed with an infusion solution, sterile precautions should be observed. Since infusion solutions generally do not contain preservatives, mixtures should be used within 24 hours. DOSAGE REQUIREMENTS ARE VARIABLE AND MUST BE INDIVIDUALIZED ON THE BASIS OF THE DISEASE AND THE RESPONSE OF THE PATIENT. Intravenous and Intramuscular Injection The initial dosage of dexamethasone sodium phosphate injection varies from 0.5 to 9 mg a day depending on the disease being treated. In less severe diseases doses lower than 0.5 mg may suffice, while in severe diseases doses higher than 9 mg may be required. The initial dosage should be maintained or adjusted until the patient’s response is satisfactory. If a satisfactory clinical response does not occur after a reasonable period of time, discontinue dexamethasone sodium phosphate injection and transfer the patient to other therapy. After a favorable initial response, the proper maintenance dosage should be determined by decreasing the initial dosage in small amounts to the lowest dosage that maintains an adequate clinical response. Patients should be observed closely for signs that might require dosage adjustment, including changes in clinical status resulting from remissions or exacerbations of the disease, individual drug responsiveness, and the effect of stress (e.g., surgery, infection, trauma). During stress it may be necessary to increase dosage temporarily. If the drug is to be stopped after more than a few days of treatment, it usually should be withdrawn gradually. When the intravenous route of administration is used, dosage usually should be the same as the oral dosage. In certain overwhelming, acute, life-threatening situations, however, administration in dosages exceeding the usual dosages may be justified and may be in multiples of the oral dosages. The slower rate of absorption by intramuscular administration should be recognized. Shock There is a tendency in current medical practice to use high (pharmacologic) doses of corticosteroids for the treatment of unresponsive shock. The following dosages of dexamethasone sodium phosphate injection have been suggested by various authors: Author Dosage Cavanagh 1 3 mg/kg of body weight per 24 hours by constant intravenous infusion after an initial intravenous injection of 20 mg Dietzman 2 2 to 6 mg/kg of body weight as a single intravenous injection Frank 3 40 mg initially followed by repeat intravenous injection every 4 to 6 hours while shock persists Oaks 4 40 mg initially followed by repeat intravenous injection every 2 to 6 hours while shock persists Schumer 5 1 mg/kg of body weight as a single intravenous injection Administration of high dose corticosteroid therapy should be continued only until the patient’s condition has stabilized and usually not longer than 48 to 72 hours. Although adverse reactions associated with high dose, short-term corticosteroid therapy are uncommon, peptic ulceration may occur. Cerebral Edema Dexamethasone sodium phosphate injection is generally administered initially in a dosage of 10 mg intravenously followed by four mg every six hours intramuscularly until the symptoms of cerebral edema subside. Response is usually noted within 12 to 24 hours and dosage may be reduced after two to four days and gradually discontinued over a period of five to seven days. For palliative management of patients with recurrent or inoperable brain tumors, maintenance therapy with 2 mg two or three times a day may be effective. Acute Allergic Disorders In acute, self-limited allergic disorders or acute exacerbations of chronic allergic disorders, the following dosage schedule combining parenteral and oral therapy is suggested: Dexamethasone sodium phosphate injection, first day , 4 or 8 mg intramuscularly. Dexamethasone tablets, 0.75 mg: second and third days, 4 tablets in two divided doses each day; fourth day , 2 tablets in two divided doses; fifth and sixth days, 1 tablet each day; seventh day, no treatment; eighth day, follow-up visit. This schedule is designed to ensure adequate therapy during acute episodes, while minimizing the risk of overdosage in chronic cases. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever the solution and container permit. Intravenous and Intramuscular Injection The initial dosage of dexamethasone sodium phosphate injection varies from 0.5 to 9 mg a day depending on the disease being treated. In less severe diseases doses lower than 0.5 mg may suffice, while in severe diseases doses higher than 9 mg may be required. The initial dosage should be maintained or adjusted until the patient’s response is satisfactory. If a satisfactory clinical response does not occur after a reasonable period of time, discontinue dexamethasone sodium phosphate injection and transfer the patient to other therapy. After a favorable initial response, the proper maintenance dosage should be determined by decreasing the initial dosage in small amounts to the lowest dosage that maintains an adequate clinical response. Patients should be observed closely for signs that might require dosage adjustment, including changes in clinical status resulting from remissions or exacerbations of the disease, individual drug responsiveness, and the effect of stress (e.g., surgery, infection, trauma). During stress it may be necessary to increase dosage temporarily. If the drug is to be stopped after more than a few days of treatment, it usually should be withdrawn gradually. When the intravenous route of administration is used, dosage usually should be the same as the oral dosage. In certain overwhelming, acute, life-threatening situations, however, administration in dosages exceeding the usual dosages may be justified and may be in multiples of the oral dosages. The slower rate of absorption by intramuscular administration should be recognized. Shock There is a tendency in current medical practice to use high (pharmacologic) doses of corticosteroids for the treatment of unresponsive shock.

For palliative management of patients with recurrent or inoperable brain tumors, maintenance therapy with 2 mg two or three times a day may be effective.

WARNINGS AND PRECAUTIONS • Alterations in Endocrine Function: Hypothalamic-pituitary adrenal (HPA) axis suppression, Cushing’s syndrome, and hyperglycemia can occur. Monitor patients for these conditions with chronic use. ( ‎5.1 ) • Immunosuppression and Increased Risk of Infections: Increased risk of new, exacerbation, dissemination, or reactivation of latent infections. (‎ 5.2 ) • Alteration in Cardiovascular/Renal Function: Monitor for elevated blood pressure and sodium, and for decreased potassium levels. (‎ 5.3 ) • Venous and Arterial Thromboembolism: Risk increased; consider anticoagulant prophylaxis and monitor for evidence of thromboembolism. (‎ 5.4 ) • Vaccination: Avoid the administration of live or live attenuated vaccines in patients receiving immunosuppressive doses of corticosteroids. ( ‎5.5 ) • Ophthalmic Effects: May include cataracts, infections, and glaucoma. (‎ 5.6 ) • Gastrointestinal Perforation: Avoid use in active or latent peptic ulcers, diverticulitis, fresh intestinal anastomoses, and nonspecific ulcerative colitis, since they may increase the risk of a perforation. (‎ 5.7 ) • Osteoporosis: Increased risk; monitor for changes in bone density with chronic use. (‎ 5.8 ) • Behavioral and Mood Disturbances: May include euphoria, insomnia, mood swings, personality changes, severe depression, and psychosis. Monitor for signs and symptoms and manage promptly. ( ‎5.10 ) • Kaposi’s Sarcoma: Kaposi’s sarcoma has been reported to occur in patients receiving corticosteroid therapy, most often for chronic conditions. (‎ 5.11 ) • Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus. (‎ 5.13 , ‎8.1 ) 5.1 Alterations in Endocrine Function Corticosteroids, such as HEMADY, can cause serious and life-threatening alterations in endocrine function, especially with chronic use. Monitor patients receiving HEMADY for adrenal insufficiency after corticosteroid withdrawal and Cushing’s syndrome and hyperglycemia while receiving corticosteroids. In addition, patients with hypopituitarism, primary adrenal insufficiency, or congenital adrenal hyperplasia, altered thyroid function, or pheochromocytoma may be at risk for adverse endocrine events. Risk of Adrenal Insufficiency Following Corticosteroid Withdrawal Corticosteroids can produce reversible hypothalamic-pituitary adrenal (HPA) axis suppression, with the potential for the development of secondary adrenal insufficiency after withdrawal of corticosteroid treatment. Acute adrenal insufficiency can occur if glucocorticoids are withdrawn abruptly and can be fatal. The degree and duration of adrenocortical insufficiently produced is variable among patients and depends on the dose, frequency, and duration of glucocorticoid therapy. The risk may be reduced by gradually tapering the corticosteroid dose when withdrawing treatment. This insufficiency may persist for months after discontinuation of therapy; therefore, in any situation of stress occurring during that period, corticosteroid therapy should be reinstituted. For patients already taking corticosteroids during times of stress, the dosage may have to be increased. A steroid “withdrawal syndrome”, seemingly unrelated to adrenocortical insufficiency, may also occur following abrupt discontinuance of corticosteroids. This syndrome includes symptoms such as: anorexia, nausea, vomiting, lethargy, headache, fever, joint pain, desquamation, myalgia, and/or weight loss. These effects are thought to be due to the sudden change in glucocorticoid concentration rather than to low corticosteroid levels. Cushing’s Syndrome Cushing’s syndrome (hypercortisolism) may occur with prolonged exposure to exogenous corticosteroids, including HEMADY. Symptoms include hypertension, truncal obesity and thinning of the limbs, purple striae, facial rounding, facial plethora, muscle weakness, easy and frequent bruising with thin fragile skin, posterior neck fat deposition, osteopenia, acne, amenorrhea, hirsutism and psychiatric abnormalities. Using the lowest dose of corticosteroid for the shortest duration possible may reduce the risk. Hyperglycemia Corticosteroids can increase blood glucose, worsen pre-existing diabetes, and predispose those on long-term therapy to diabetes mellitus, and may reduce the effect of the antidiabetic drugs. Monitor blood glucose at regular intervals. For patients with hyperglycemia, anti-diabetic treatment should be initiated or adjusted accordingly. Considerations for Use in Patients with Altered Thyroid Function Metabolic clearance of corticosteroids is decreased in hypothyroid patients and increased in hyperthyroid patients. Changes in thyroid status of the patient may necessitate a dose adjustment of the corticosteroid. When concomitant administration of corticosteroids and levothyroxine is required, administration of corticosteroid should precede the initiation of levothyroxine therapy to avoid adrenal crisis. Pheochromocytoma Crisis There have been reports of pheochromocytoma crisis, which can be fatal, after administration of systemic corticosteroids. In patients with suspected or identified pheochromocytoma, consider the risk of pheochromocytoma crisis prior to administering HEMADY. 5.2 Immunosuppression and Increased Risk of Infection Corticosteroids, including HEMADY, suppress the immune system and increase the risk of infection with any pathogen, including viral, bacterial, fungal, protozoan, or helminthic pathogens. Corticosteroids can: Reduce resistance to new infections Exacerbate existing infections Increase the risk of disseminated infections Increase the risk of reactivation or exacerbation of latent infections Mask some signs of infection Corticosteroid-associated infections can be mild but can be severe and at times fatal. The rate of infectious complications increases with increasing corticosteroid dosages. Monitor for the development of infection and consider HEMADY withdrawal or dosage reduction as needed. Tuberculosis If HEMADY is used to treat a condition in patients with latent tuberculosis or tuberculin reactivity, reactivation of tuberculosis may occur. Closely monitor such patients for reactivation. During prolonged HEMADY therapy, patients with latent tuberculosis or tuberculin reactivity should receive chemoprophylaxis. Varicella Zoster and Measles Viral Infections Varicella and measles can have a serious or even fatal course in non-immune pediatric and adult patients taking corticosteroids, including HEMADY. In corticosteroid-treated patients who have not had these diseases or are non-immune, particular care should be taken to avoid exposure to varicella and measles: If a HEMADY-treated patient is exposed to varicella, prophylaxis with varicella zoster immune globulin may be indicated. If varicella develops, treatment with antiviral agents may be considered. If a HEMADY-treated patient is exposed to measles, prophylaxis with immunoglobulin may be indicated. Hepatitis B Virus Reactivation Hepatitis B virus reactivation can occur in patients who are hepatitis B carriers treated with immunosuppressive dosages of corticosteroids, including HEMADY. Reactivation can also occur infrequently in corticosteroid-treated patients who appear to have resolved hepatitis B infection. Screen patients for hepatitis B infection before initiating immunosuppressive (e.g., prolonged) treatment with HEMADY. For patients who show evidence of hepatitis B infection, recommend consultation with physicians with expertise in managing hepatitis B regarding monitoring and consideration for hepatitis B antiviral therapy. Fungal Infections Corticosteroids, including HEMADY, may exacerbate systemic fungal infections; therefore, avoid HEMADY use in the presence of such infections unless HEMADY is needed to control drug reactions. For patients on chronic HEMADY therapy who develop systemic fungal infections, HEMADY withdrawal or dosage reduction is recommended. Amebiasis Corticosteroids

CONTRAINDICATIONS Ocular or periocular infections ( 4.1 ) Glaucoma ( 4.2 ) Torn or ruptured posterior lens capsule ( 4.3 ) Hypersensitivity ( 4.4 ) 4.1 Ocular or Periocular Infections OZURDEX (dexamethasone intravitreal implant) is contraindicated in patients with active or suspected ocular or periocular infections including most viral diseases of the cornea and conjunctiva, including active epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, varicella, mycobacterial infections, and fungal diseases. 4.2 Glaucoma OZURDEX is contraindicated in patients with glaucoma, who have cup to disc ratios of greater than 0.8. 4.3 Torn or Ruptured Posterior Lens Capsule OZURDEX is contraindicated in patients whose posterior lens capsule is torn or ruptured because of the risk of migration into the anterior chamber. Laser posterior capsulotomy in pseudophakic patients is not a contraindication for OZURDEX use. 4. 4 Hypersensitivity OZURDEX is contraindicated in patients with known hypersensitivity to any components of this product [see Adverse Reactions ( 6 )] .

DRUG INTERACTIONS • Avoid concomitant use of strong CYP3A4 inhibitors or inducers. (‎ 7.1 ) • Concomitant therapies such as erythropoietin stimulating agents or estrogen containing therapies may have an increased risk of thromboembolism. ( ‎7.2 ) 7.1 Effect of Other Drugs on HEMADY Strong CYP3A4 inhibitors Coadministration of strong and moderate CYP3A4 inhibitors increased dexamethasone exposure [see Clinical Pharmacology (‎ 12.3 )] , which may increase the risk of adverse reactions [see Warnings and Precautions (‎ 5 ) and Adverse Reactions (‎ 6 )] . Avoid coadministration of strong CYP3A4 inhibitors or consider alternative medication that are not strong CYP3A4 inhibitors. If concomitant use of strong CYP3A4 inhibitors cannot be avoided, closely monitor for adverse drug reactions. Strong CYP3A4 inducers Coadministration of strong CYP3A4 inducers may decrease dexamethasone exposure [see Clinical Pharmacology (‎ 12.3 )] , which may result in loss of efficacy. Avoid coadministration of strong CYP3A4 inducers or consider alternative medication that are not CYP3A4 inducers. If concomitant use strong CYP3A4 inducers cannot be avoided, consider increasing the dose of HEMADY. Cholestyramine Cholestyramine may increase the clearance of corticosteroids and potentially decrease corticosteroid exposure. Avoid coadministration of cholestyramine and HEMADY and consider alternative agents. Anticholinesterases Concomitant use of anticholinesterase agents and corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, anticholinesterase agents should be withdrawn at least 24 hours before initiating corticosteroid therapy. Ephedrine Ephedrine may decrease dexamethasone exposure. Decreased exposure may result in loss of efficacy. Consider increasing the dose of HEMADY when used concomitantly with ephedrine. Estrogens, Including Oral Contraceptives Estrogens may decrease the hepatic metabolism of certain corticosteroids and increase exposures, which may increase the risk of adverse reactions [see Warnings and Precautions ( ‎5 ) and Adverse Reactions (‎ 6 )] . 7.2 Effect of HEMADY on Other Drugs CYP3A4 Substrates Coadministration of dexamethasone with drugs that are CYP3A4 substrates may decrease the concentration of these drugs. This may result in loss of efficacy of these drugs. Oral Anticoagulants Coadministration of anticoagulants with corticosteroids may reduce the response to anticoagulants [see Adverse Reactions (‎ 6 )] . Frequently monitor coagulation indices to maintain the desired anticoagulant effect when administered with HEMADY. Amphotericin B Injection and Potassium-Depleting Agents Sodium retention with resultant edema and potassium loss may occur in patients receiving corticosteroids [see Warnings and Precautions ( ‎5.3 ), and Adverse Reactions (‎ 6 )] . Closely monitor potassium levels when potassium-depleting agents are coadministered with HEMADY. In addition, there have been cases reported in which concomitant use of amphotericin B and hydrocortisone was followed by cardiac enlargement and congestive heart failure. Antidiabetics Corticosteroids, including HEMADY, may increase blood glucose concentrations [see Warnings and Precautions (‎ 5.1 ) and Adverse Reactions (‎ 6 )] . Consider adjusting the dose of antidiabetic agents, as necessary, when coadministered with HEMADY. Isoniazid Serum concentrations of isoniazid may be decreased with corticosteroids. Cyclosporine Increased activity of both cyclosporine and corticosteroids may occur when the two are used concurrently. Convulsions have been reported with this concurrent use. Digitalis Glycosides Patients on digitalis glycosides may be at increased risk of arrhythmias due to hypokalemia [ see Warnings and Precautions (‎ 5.3 ) and Adverse Reactions (‎ 6 )] . Nonsteroidal Anti-Inflammatory Agents (NSAIDS) Concomitant use of aspirin (or other nonsteroidal anti-inflammatory agents) and corticosteroids increases the risk of gastrointestinal side effects [see Warnings and Precautions (‎ 5.7 ) and Adverse Reactions (‎ 6 )] . The clearance of salicylates may be increased with concurrent use of corticosteroids. Monitor for toxicity when aspirin is used in conjunction with HEMADY in hypoprothrombinemia. Phenytoin In post-marketing experience, there have been reports of both increases and decreases in phenytoin levels with dexamethasone coadministration, leading to alterations in seizure control. Vaccines Patients on corticosteroid therapy may exhibit a diminished response to toxoids and live or inactivated vaccines due to inhibition of antibody response. Corticosteroids may also potentiate the replication of some organisms contained in live attenuated vaccines. If possible, defer routine administration of vaccines or toxoids until HEMADY therapy is discontinued [see Warnings and Precautions (‎ 5.5 )] . Concomitant Therapies that May Increase the Risk of Thromboembolism Erythropoietic agents, or other agents that may increase the risk of thromboembolism, such as estrogen containing therapies, coadministered with HEMADY may increase the risk of thromboembolism. Monitor for risk of thromboembolism in patients with MM receiving anti-myeloma products with HEMADY [see Warnings and Precautions (‎ 5.4 )] . Thalidomide Toxic epidermal necrolysis has been reported with concomitant use of thalidomide. Closely monitor for toxicity when thalidomide is coadministered with HEMADY. 7.3 Laboratory Test Interference Skin Tests Corticosteroids may suppress reactions to skin tests.

ADVERSE REACTIONS In controlled studies, the most common adverse reactions reported by 20–70% of patients were cataract, increased intraocular pressure and conjunctival hemorrhage. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact AbbVie at 1-800-633-9110 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. Figure 1: Mean IOP during the study 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Adverse reactions associated with ophthalmic steroids including OZURDEX include elevated intraocular pressure, which may be associated with optic nerve damage, visual acuity and field defects, posterior subcapsular cataract formation, secondary ocular infection from pathogens including herpes simplex, and perforation of the globe where there is thinning of the cornea or sclera. Retinal Vein Occlusion and Posterior Segment Uveitis The following information is based on the combined clinical trial results from 3 initial, randomized, 6-month, sham-controlled studies (2 for retinal vein occlusion and 1 for posterior segment uveitis): Table 1: Adverse Reactions Reported by Greater than 2% of Patients MedDRA Term OZURDEX N=497 (%) Sham N=498 (%) Intraocular pressure increased 125 (25%) 10 (2%) Conjunctival hemorrhage 108 (22%) 79 (16%) Eye pain 40 (8%) 26 (5%) Conjunctival hyperemia 33 (7%) 27 (5%) Ocular hypertension 23 (5%) 3 (1%) Cataract 24 (5%) 10 (2%) Vitreous detachment 12 (2%) 8 (2%) Headache 19 (4%) 12 (2%) Increased IOP with OZURDEX peaked at approximately week 8. During the initial treatment period, 1% (3/421) of the patients who received OZURDEX required surgical procedures for management of elevated IOP. Following a second injection of OZURDEX in cases where a second injection was indicated, the overall incidence of cataracts was higher after 1 year. In a 2 year observational study, among patients who received >2 injections, the most frequent adverse reaction was cataract 54% (n= 96 out of 178 phakic eyes at baseline). Other frequent adverse reactions from the 283 treated eyes, regardless of lens status at baseline, were increased IOP 24% (n = 68) and vitreous hemorrhage 6.0% (n = 17). Diabetic Macular Edema The following information is based on the combined clinical trial results from 2 randomized, 3-year, sham-controlled studies in patients with diabetic macular edema. Discontinuation rates due to the adverse reactions listed in Table 2 were 3% in the OZURDEX group and 1% in the Sham group. The most common ocular (study eye) and non-ocular adverse reactions are shown in Tables 2 and 3: Table 2: Ocular Adverse Reactions Reported by ≥ 1% of Patients and Non-ocular Adverse Reactions Reported by ≥ 5% of Patients MedDRA Term OZURDEX N=324 (%) Sham N=328 (%) Ocular Cataract 1 166/243 2 (68%) 49/230 (21%) Conjunctival hemorrhage 73 (23%) 44 (13%) Visual acuity reduced 28 (9%) 13 (4%) Conjunctivitis 19 (6%) 8 (2%) Vitreous floaters 16 (5%) 6 (2%) Conjunctival edema 15 (5%) 4 (1%) Dry eye 15 (5%) 7 (2%) Vitreous detachment 14 (4%) 8 (2%) Vitreous opacities 11 (3%) 3 (1%) Retinal aneurysm 10 (3%) 5 (2%) Foreign body sensation 7 (2%) 4 (1%) Corneal erosion 7 (2%) 3 (1%) Keratitis 6 (2%) 3 (1%) Anterior Chamber Inflammation 6 (2%) 0 (0%) Retinal tear 5 (2%) 2 (1%) Eyelid ptosis 5 (2%) 2 (1%) Non-ocular Hypertension 41 (13%) 21 (6%) Bronchitis 15 (5%) 8 (2%) 1 Includes cataract, cataract nuclear, cataract subcapsular, lenticular opacities in patients who were phakic at baseline. Among these patients, 61% of OZURDEX subjects vs. 8% of sham-controlled subjects underwent cataract surgery. 2 243 of the 324 OZURDEX subjects were phakic at baseline; 230 of 328 sham-controlled subjects were phakic at baseline. Increased Intraocular Pressure Table 3: Summary of Elevated Intraocular Pressure (IOP) Related Adverse Reactions IOP Treatment: N (%) OZURDEX N=324 Sham N=328 IOP elevation ≥10 mm Hg from Baseline at any visit 91 (28%) 13 (4%) ≥30 mm Hg IOP at any visit 50 (15%) 5 (2%) Any IOP lowering medication 136 (42%) 32 (10%) Any surgical intervention for elevated IOP * 4 (1.2%) 1 (0.3%) * OZURDEX: 1 surgical trabeculectomy for steroid-induced IOP increase, 1 surgical trabeculectomy for iris neovascularization, 1 laser iridotomy, 1 surgical iridectomy Sham: 1 laser iridotomy The increase in mean IOP was seen with each treatment cycle, and the mean IOP generally returned to baseline between treatment cycles (at the end of the 6 month period) shown below: Figure 1: Mean IOP during the study Cataracts and Cataract Surgery At baseline, 243 of the 324 OZURDEX subjects were phakic; 230 of 328 sham-controlled subjects were phakic. The incidence of cataract development in patients who had a phakic study eye was higher in the OZURDEX group (68%) compared with Sham (21%). The median time of cataract being reported as an adverse event was approximately 15 months in the OZURDEX group and 12 months in the Sham group. Among these patients, 61% of OZURDEX subjects vs. 8% of sham-controlled subjects underwent cataract surgery, generally between Month 18 and Month 39 (Median Month 21 for OZURDEX group and 20 for Sham) of the studies. 6.2 Postmarketing Experience The following reactions have been identified during post-approval use of OZURDEX in clinical practice. Because they are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The reactions, which have been chosen for inclusion due to either their seriousness, frequency of reporting, possible causal connection to OZURDEX, or a combination of these factors, include: complication of device insertion resulting in ocular tissue injury including sclera, subconjunctiva, lens and retina (implant misplacement), device dislocation with or without corneal edema/corneal decompensation, endophthalmitis, hypotony of the eye (associated with vitreous leakage due to injection), and retinal detachment.

CLINICAL PHARMACOLOGY Dexamethasone sodium phosphate injection has a rapid onset but short duration of action when compared with less soluble preparations. Because of this, it is suitable for the treatment of acute disorders responsive to adrenocortical steroid therapy. Naturally occurring glucocorticoids (hydrocortisone and cortisone), which also have salt-retaining properties, are used as replacement therapy in adrenocortical deficiency states. Their synthetic analogs, including dexamethasone, are primarily used for their potent anti-inflammatory effects in disorders of many organ systems. Glucocorticoids cause profound and varied metabolic effects. In addition, they modify the body's immune responses to diverse stimuli. At equipotent anti-inflammatory doses, dexamethasone almost completely lacks the sodium-retaining property of hydrocortisone and closely related derivatives of hydrocortisone.
