Patient Education

Prednisolone


Prednisolone is used alone or with other medications to treat the symptoms of low corticosteroid levels (lack of certain substances that are usually produced by the body and are needed for normal body functioning). Prednisolone is also used to treat certain conditions that affect the blood, skin, eyes, central nervous system, kidneys, lungs, stomach, and intestines. It is also used to treat allergic reactions; and certain types of arthritis; multiple sclerosis (a disease in which the nerves do not function properly); and to help prevent transplant rejection (attack of the transplanted organ by the body) in certain adults who have received a transplant. Prednisolone is also sometimes used to treat symptoms from certain types of cancer. Prednisolone is in a class of medications called corticosteroids. It works by reducing swelling and redness and by changing the way the immune system works.

Prednisolone Ophthalmic


Ophthalmic prednisolone reduces the irritation, redness, burning, and swelling of eye inflammation caused by chemicals, heat, radiation, infection, allergy, or foreign bodies in the eye. It sometimes is used after eye surgery. Prednisolone is in a class of medications called steroids. It prevents swelling and redness 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.
