Avoid ophthalmic use if corneal ulceration is present.

약물 상호작용

• NSAIDs (e.g., carprofen, meloxicam): Significantly increased risk of severe gastrointestinal ulceration and bleeding.
• Insulin: Dexamethasone induces insulin resistance, antagonizing the hypoglycemic effect of insulin and increasing requirements in diabetic patients.
• Phenobarbital: May induce hepatic enzymes, increasing the metabolism and clearance of dexamethasone.
• Diuretics (potassium-depleting): Increased risk of hypokalemia.
