Background
Dexamethasone is a synthetic glucocorticoid widely used for its potent anti-inflammatory and immunosuppressive effects. It treats a broad range of conditions, including autoimmune diseases, allergic reactions, certain cancers, and severe COVID-19 cases. Despite its effectiveness, dexamethasone is a double-edged sword: inappropriate or unsupervised use can lead to serious side effects and dangerous drug interactions. Understanding these risks is essential for both healthcare providers and patients to ensure safe and effective therapy.
