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.
