Patient Education

Hydrocortisone


Hydrocortisone, a corticosteroid, is similar to a natural hormone produced by your adrenal glands. It is often used to replace this chemical when your body does not make enough of it. It relieves inflammation (swelling, heat, redness, and pain) and is used to treat certain forms of arthritis; skin, blood, kidney, eye, thyroid, and intestinal disorders (e.g., colitis); severe allergies; and asthma. Hydrocortisone is also used to treat certain types of cancer. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
