Steroids to Treat Arthritis
Steroids (short for corticosteroids) are synthetic drugs that closely resemble cortisol, a hormone that your body produces naturally. Steroids work by decreasing inflammation and reducing the activity of the immune system. They are used to treat a variety of inflammatory diseases and conditions.
Corticosteroids are different from anabolic steroids, which some athletes use to build bigger muscles. Examples of corticosteroid medications include cortisone, prednisone and methylprednisolone.
How Are Steroids Given?
Steroids can be given topically, by mouth (orally) or by injection. When injected, they can be given into a vein or muscle, directly into a joint or bursa (lubricating sac between certain tendons and the bones beneath them) or around tendons and other soft tissue areas. When only a specific area of the body is affected, steroids can be given as eye drops, eardrops and skin creams.
How Do Steroids Work?
Steroids work by decreasing inflammation and reducing the activity of the immune system. Inflammation is a process by which the body's white blood cells and chemicals protect the body against infection and foreign substances such as bacteria and viruses.
In certain diseases, however, the body's defense system (immune system) doesn't function properly. This may cause inflammation to work against the body's own tissues and cause damage. Inflammation is characterized by redness, warmth, swelling and pain.
Steroids reduce the production of inflammatory chemicals in order to minimize tissue damage. Steroids also reduce the activity of the immune system by affecting the function of white blood cells.
What Conditions Are Treated With Steroids?
Steroids are used to treat a variety of conditions in which the body's defense system malfunctions and causes tissue damage. Steroids are used as the main treatment for certain inflammatory conditions, such as systemic vasculitis (inflammation of blood vessels) and myositis (inflammation of muscle). They may also be used selectively to treat inflammatory conditions such as rheumatoid arthritis, lupus or Sjogren's syndrome.
What Are the Benefits of Steroids?
When inflammation threatens to damage critical body organs, steroids can be organ saving and, in many instances, life-saving. For example, they may help prevent the progression of kidney inflammation, which can lead to kidney failure in people who have lupus or vasculitis. For these people, steroid therapy may eliminate the need for kidney dialysis or transplantation.
Low doses of steroids may provide significant relief from pain and stiffness for people with rheumatoid arthritis. Temporary use of higher doses of steroids may help a person recover from a severe flare-up of arthritis.
Why Are Steroids Injected?
Injecting steroids into one or two areas of inflammation allows doctors to deliver a high dose of medication directly to the problem area. When doctors give steroids by mouth or in a vein, they cannot be sure an adequate amount will eventually reach the problem area.
