Treatment generally consists of corticosteroid medications. You know them simply as steroids. Your doctor will also prescribe low doses of chemotherapy drugs. The goal of this type of therapy is to suppress the abnormal immune response that has led to blood vessel damage.
Other medications may include methotrexate or cyclophosphamide (Cytoxin) and a biologic drug called tocilizumab (Actemra). You'll get tocilizumab as an injection under the skin to lower the dose of steroids you'd otherwise need. You may also get it along with steroids.
