Decadron (Dexamethasone Pill; Oral)

(dex a meth' a sone)

Dexamethasone injection is used to treat severe allergic reactions. It is used in the management of certain types of edema (fluid retention and swelling; excess fluid held in body tissues,) gastrointestinal disease, and certain types of arthritis. Dexamethasone injection is also used for diagnostic testing. Dexamethasone injection is also used to treat certain conditions that affect the blood, skin, eyes, thyroid, kidneys, lungs, and nervous system. It is sometimes used in combination with other medications to treat symptoms of low corticosteroid levels (lack of certain substances that are usually produced by the body and are needed for normal body functioning) and in the management of certain types of shock. Dexamethasone injection is in a class of medications called corticosteroids. It works to treat people with low levels of corticosteroids by replacing steroids that are normally produced naturally by the body. It also works to treat other conditions by reducing swelling and redness and by changing the way the immune system works.

Dexamethasone injection comes as powder to be mixed with liquid to be injected intramuscularly (into a muscle) or intravenously (into a vein). Your personal dosing schedule will depend on your condition and on how you respond to treatment. You may receive dexamethasone injection in a hospital or medical facility, or you may be given the medication to use at home. If you will be using dexamethasone injection at home, your healthcare provider will show you how to inject the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions. Ask your healthcare provider what to do if you have any problems using dexamethasone injection. Your doctor may change your dose of dexamethasone injection during your treatment to be sure that you are always using the lowest dose that works for you. Your doctor may also need to change your dose if you experience unusual stress on your body such as surgery, illness, or infection. Tell your doctor if your symptoms improve or get worse or if you get sick or have any changes in your health during your treatment.
