Some patients may use it as a topical medication for eczema or other skin conditions. Ultimately, however, patients must understand how this medication works before determining if it is the best treatment for their needs.
How It Works
Dexamethasone is part of a group of medicines called glucocorticosteroids. These medicines weaken the immune system and decrease inflammation. The medication reduces inflammation by stopping polymorphonuclear leukocytes (white blood cells) from reaching the inflamed area. White blood cells combat infection. Since dexamethasone blocks their normal action, patients are more susceptible to infection while taking this medication. It helps patients with adrenal insufficiency too. Patients with this condition have lower levels of the hormones released by the adrenal gland, and dexamethasone replaces them. Scientists believe that this medication may also work by causing certain cells to die.
