Prednisone is a corticosteroid with potent anti-inflammatory effects. Corticosteroids are a cornerstone of treating most types of vasculitis, and are often used in combination with other immunosuppressive medications. Prednisone works very quickly, and is therefore used (often at high doses) at the time of initial diagnosis to bring vasculitis under control. Then, prednisone is gradually reduced (“tapered”) while another immunosuppressive drug is started for long term treatment. Over time, the “steroid-sparing” immunosuppressive drug is used to control vasculitis, and prednisone is eventually stopped. Side EffectsCorticosteroids cause a long list of side effects, making it dangerous to use these drugs at significant doses for long term treatment. The side effects of prednisone are related to: 1) the amount of steroid a patient takes in his/her daily dose, and 2) the length of time the patient remains on the medication. We emphasize that not all side effects occur in all patients. Despite the numerous potential side effects of corticosteroids listed below, their introduction into patient care more than 50 years ago revolutionized the treatment of many diseases, including vasculitis. When used properly, these drugs save lives and avert threats to the function of important organs.

The higher the steroid dose and the longer the duration of therapy, the greater the risk of infection. The risk is also increased when patients receive combinations of immunosuppressive medications, such as cyclophosphamide (cytoxan) and prednisone. The risk of some infections can be greatly reduced by taking specific types of antibiotics prophylactically (such as Bactrim).Pictured below is woman under treatment with prednisone and methotrexate for vasculitis and a concurrent neurologic condition (myasthenia gravis) developed painful vesicles in her mouth. The vesicles were confirmed by culture to be caused by reactivation of a Herpes simplex infection, and responded to treatment with acyclovir.Weight GainWeight gain is usually the most dreaded side–effects of steroids, incurred to some degree by nearly all patients who take them. The amount of weight gain varies from individual to individual. In addition to causing weight gain, prednisone leads to a redistribution of body fat to places that are undesirable, particularly the face, back of the neck, and abdomen. Pictured below is an example of redistribution of body fat to the back of the neck. Accumulation of fat in this area is sometimes referred to as a “buffalo hump”.Another example of this “redistribution” is pictured below. Supraclavical “fat pads” are collections of fat at the base of the
