It is used to reduce inflammation and suppress excessive immune-system activity in a wide range of medical conditions. It may be prescribed for certain **allergic, inflammatory, autoimmune and other steroid-responsive conditions**. Because dexamethasone can affect the immune system, metabolism and adrenal function, it should be used only under appropriate medical supervision. ## KEY BENEFITS * Helps reduce inflammation * Helps suppress excessive immune-system activity * Can relieve swelling and inflammatory symptoms * May help control severe allergic and inflammatory reactions * Useful in certain autoimmune and steroid-responsive conditions * Provides potent corticosteroid activity at relatively low doses ## USES / INDICATIONS Dexamethasone 0.5 mg may be prescribed for selected conditions, including: * Severe allergic or inflammatory conditions * Certain autoimmune disorders * Rheumatic and musculoskeletal inflammatory conditions * Certain skin disorders * Certain respiratory or inflammatory conditions * Cerebral edema associated with appropriate underlying conditions * Certain endocrine disorders requiring corticosteroid therapy * Some hematological disorders * Other steroid-responsive conditions as determined by a healthcare professional The indication depends on the patient's condition, severity and treatment plan. ## HOW IT WORKS Dexamethasone is a **synthetic glucocorticoid corticosteroid**. It enters cells and binds to glucocorticoid receptors, altering the expression of genes involved in inflammation and immune responses. This reduces the production and activity of various inflammatory substances. As a result, dexamethasone can reduce **inflammation, swelling and excessive immune-system activity**. ## DOSAGE & ADMINISTRATION The appropriate dose varies substantially depending on the condition being treated. * Take dexamethasone **exactly as prescribed**. * The dose may range from low doses to substantially higher doses depending on the medical indication. * Take it at the same time each day when possible. * It may be taken with food or milk to reduce stomach irritation. * Do not change the dose without medical advice. * **Do not stop long-term dexamethasone treatment suddenly**, as the body may need time to restore normal adrenal hormone production. * Your doctor may gradually reduce the dose when treatment is discontinued after prolonged use. ### Missed Dose Take the missed dose when remembered unless it is close to the next scheduled dose.
