Description
Dexamethasone Injection is a potent corticosteroid used to treat severe inflammation, allergic reactions, certain cancers, and immune-related disorders. It works by suppressing the immune system and reducing inflammation. This injection is commonly used in hospitals for conditions such as severe asthma, rheumatoid arthritis, cerebral edema, septic shock, and COVID-19 management (as adjunct therapy).
