Dexamethasone - injection
Dexamethasone - injection
This medication is used to treat various conditions such as severe allergic reactions, arthritis, blood diseases, breathing problems, certain cancers, eye diseases, intestinal disorders, and skin diseases. It is also used to test for an adrenal gland disorder (Cushing's syndrome). It decreases your body's natural defensive response and reduces symptoms such as swelling and allergic-type reactions. Dexamethasone is a corticosteroid hormone (glucocorticoid). This injectable form of dexamethasone is used when a similar drug cannot be taken by mouth or when a very fast response is needed, especially in patients with severe medical conditions. Talk to your doctor about the risks and benefits of dexamethasone, especially if it is to be injected near your spine (epidural). Rare but serious side effects may occur with epidural use.
This drug may also be used with other medications as a replacement for certain hormones.
