Patient Education

Methylprednisolone Injection


Methylprednisolone injection is used to treat severe allergic reactions. Methylprednisolone injection is used in the management of multiple sclerosis (a disease in which the nerves do not function properly), lupus (a disease in which the body attacks many of its own organs), gastrointestinal disease, and certain types of arthritis. Methylprednisolone injection is also used to treat certain conditions that affect the blood, skin, eyes, nervous system, thyroid, kidneys, and lungs. It is sometimes used in combination with other medications to treat symptoms of low corticosteroid levels (lack of certain substances that are usually produced by the body and are needed for normal body functioning). Methylprednisolone injection is in a class of medications called corticosteroids. It works to treat people with low levels of corticosteroids by replacing steroids that are normally produced naturally by the body. It also works to treat other conditions by reducing swelling and redness and by changing the way the immune system works.

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.
