Corticosteroids are different from anabolic steroids, which some athletes use to build bigger muscles. Examples of corticosteroid medications include triamcinolone, cortisone, prednisone, and methylprednisolone.
How Are Steroids Given?
Steroids can be given topically (cream or ointment), 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.
How Do Steroids Work?
Steroids decrease inflammation and reduce 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 organisms such as bacteria and viruses.
In certain diseases, however, the body's defense system (immune system) doesn't function properly and is overactive. This may cause inflammation to work against the body's own tissues and cause tissue 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, Sjögren's syndrome, or gout.
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 transplant.
Low doses of steroids may provide significant relief from pain and stiffness for people with conditions including rheumatoid arthritis. Temporary use of higher doses of steroids may help a person recover from a severe flare-up of arthritis.
