Patient Education

Fludrocortisone Acetate


Fludrocortisone, a corticosteroid, is used to help control the amount of sodium and fluids in your body. It is used to treat Addison's disease and syndromes where excessive amounts of sodium are lost in the urine. It works by decreasing the amount of sodium that is lost (excreted) in your urine. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Steroids


You may have heard of anabolic steroids, which can have harmful effects. But there's another type of steroid - sometimes called a corticosteroid - that treats a variety of problems. These steroids are similar to hormones that your adrenal glands make to fight stress associated with illnesses and injuries. They reduce inflammation and affect the immune system.

You may need to take corticosteroids to treat

  • Arthritis
  • Asthma
  • Autoimmune diseases such as lupus and multiple sclerosis
  • Skin conditions such as eczema and rashes
  • Some kinds of cancer

Steroids are strong medicines, and they can have side effects, including weakened bones and cataracts. Because of this, you usually take them for as short a time as possible.
