"Almost all of the 41 million estimated contact lens wearers in the United States may be engaging in at least one behavior known to increase their risk of eye infections, according to a report published today by the Centers for Disease Control and"...
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Adverse event data were collected from 300 published articles containing data from controlled and uncontrolled clinical trials which evaluated over 14,000 eyes treated with different concentrations of triamcinolone acetonide.
The most common dose administered within these trials was triamcinolone acetonide 4 mg administered as primary or adjunctive therapy primarily as a single injection. The most common reported adverse events following administration of triamcinolone acetonide were elevated intraocular pressure and cataract progression. These events have been reported to occur in 20-60% of patients.
Less common reactions occurring in up to 2% include endophthalmitis (infectious and non-infectious), hypopyon, injection site reactions (described as blurring and transient discomfort), glaucoma, vitreous floaters, and detachment of retinal pigment epithelium, optic disc vascular disorder, eye inflammation, conjunctival hemorrhage and visual acuity reduced. Cases of exophthalmos have also been reported.
Common adverse reactions for systemically administered corticosteroids include fluid retention, alteration in glucose tolerance, elevation in blood pressure, behavioral and mood changes, increased appetite and weight gain.
Other reactions reported to have occurred with the administration of corticosteroids include:
Allergic Reactions: Anaphylactoid reaction, anaphylaxis, angioedema
Cardiovascular: Bradycardia, cardiac arrest, cardiac arrhythmias, cardiac enlargement, circulatory collapse, congestive heart failure, fat embolism, hypertrophic cardiomyopathy in premature infants, myocardial rupture following recent myocardial infarction, pulmonary edema, syncope, tachycardia, thromboembolism, thrombophlebitis, vasculitis
Dermatologic: Acne, allergic dermatitis, cutaneous and subcutaneous atrophy, dry scalp, edema, facial erythema, hyper or hypo-pigmentation, impaired wound healing, increased sweating, petechiae and ecchymoses, rash, sterile abscess, striae, suppressed reactions to skin tests, thin fragile skin, thinning scalp hair, urticaria
Endocrine: Abnormal fat deposits, decreased carbohydrate tolerance, development of Cushingoid state, hirsutism, manifestations of latent diabetes mellitus and increased requirements for insulin or oral hypoglycemic agents in diabetics, menstrual irregularities, moon facies, secondary adrenocortical and pituitary unresponsiveness (particularly in times of stress, as in trauma, surgery or illness), suppression of growth in children
Fluid and Electrolyte Disturbances: Potassium loss, hypokalemic alkalosis, sodium retention
Gastrointestinal: Abdominal distention, elevation in serum liver enzymes levels (usually reversible upon discontinuation), hepatomegaly, hiccups, malaise, nausea, pancreatitis, peptic ulcer with possible perforation and hemorrhage, ulcerative esophagitis
Metabolic: Negative nitrogen balance due to protein catabolism
Musculoskeletal: Aseptic necrosis of femoral and humeral heads, charcot-like arthropathy, loss of muscle mass, muscle weakness, osteoporosis, pathologic fracture of long bones, steroid myopathy, tendon rupture, vertebral compression fractures
Neurological: Arachnoiditis, convulsions, depression, emotional instability, euphoria, headache, increased intracranial pressure with papilledema (pseudo-tumor cerebri) usually following discontinuation of treatment, insomnia, meningitis, neuritis, neuropathy, paraparesis/paraplegia, paresthesia, sensory disturbances, vertigo
Reproductive: Alteration in motility and number of spermatozoa.

- Amphotericin B: There have been cases reported in which concomitant use of Amphotericin B and hydrocortisone was followed by cardiac enlargement and congestive heart failure. See Potassium depleting agents.
- Anticholinesterase agents: 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.
- Anticoagulant agents: Co-administration of corticosteroids and warfarin usually results in inhibition of response to warfarin, although there have been some conflicting reports. Therefore, coagulation indices should be monitored frequently to maintain the desired anticoagulant effect.
- Antidiabetic agents: Because corticosteroids may increase blood glucose concentrations, dosage adjustments of antidiabetic agents may be required.
- Antitubercular drugs: Serum concentrations of isoniazid may be decreased.
- CYP 3A4 inducers (e.g., barbiturates, phenytoin, carbamazepine, and rifampin): Drugs such as barbiturates, phenytoin, ephedrine, and rifampin, which induce hepatic microsomal drug metabolizing enzyme activity may enhance metabolism of corticosteroid and require that the dosage of corticosteroid be increased.
- CYP 3A4 inhibitors (e.g., ketoconazole, macrolide antibiotics): Ketoconazole has been reported to decrease the metabolism of certain corticosteroids by up to 60% leading to an increased risk of corticosteroid side effects.
- Cholestyramine: Cholestyramine may increase the clearance of corticosteroids.
- Cyclosporine: Increased activity of both cyclosporine and corticosteroids may occur when the two are used concurrently Convulsions have been reported with concurrent use.
- Digitalis: Patients on digitalis glycosides may be at increased risk of arrhythmias due to hypokalemia.
- Estrogens, including oral contraceptives: Estrogens may decrease the hepatic metabolism of certain corticosteroids thereby increasing their effect.
- NSAIDS including aspirin and salicylates: Concomitant use of aspirin or other non-steroidal antiinflammatory agents and corticosteroids increases the risk of gastrointestinal side effects. Aspirin should be used cautiously in conjunction with corticosteroids in hypoprothrombinemia. The clearance of salicylates may be increased with concurrent use of corticosteroids.
- Potassium depleting agents (e.g., diuretics, Amphotericin B): When corticosteroids are administered concomitantly with potassium-depleting agents, patients should be observed closely for development of hypokalemia.
- Skin tests: Corticosteroids may suppress reactions to skin tests.
- Toxoids and live or inactivated vaccines: Due to inhibition of antibody response, patients on prolonged corticosteroid therapy may exhibit a diminished response to toxoids and live or inactivated vaccines. Corticosteroids may also potentiate the replication of some organisms contained in live attenuated vaccines.
